#1 Lafayette Siding and Window Contractor

The Bellwether team provided excellent services throughout the process of developing and carrying out our fire-resistant (James Hardie) siding project. Teri on the sales side was very responsive and happily answered all of our questions. Dennis and the installation team communicated the requirement of our project well and did an impeccable job with the installation. We didn't even find anything to put on a punch list after they were done. Karen was patient and flexible -- a pleasure to work with on the payments. It was great to work with this team in making our mountain home a safer place to live.

Just had Bellwether install James Hardi siding on my son’s house. They did an excellent job . The communication was very good. Everyone we dealt with was friendly knowledgeable and very helpful. The crew that came out to do the work did an excellent job and cleaned up the work site very well. We have hired many contractors over the years and this was one of the best that we have worked with. Do not hesitate to have them for your project..

This was a huge project and I am so thankful we hired Bellwether! From the very beginning, my first phone call with Amy to schedule someone to come out to give us an estimate, which in itself was amazing because the house was all brick and no other company even wanted to come out and give us an estimate for siding until the brick was completely removed. I spoke with Amy and she said, no problem, we can come out right away...yea!! Then we met with Seth and he gave us an amazing estimate for the entire brick removal and the new siding....but wait, believe me with this big of a job there were many hurdles. Seth worked hand-in-hand with the company we hired to put up the deck, which was a huge help. We had to schedule this in two phases. Phase 1, brick removal, which then added to putting in all new insulation because the house was built in '68 and had blown-in insulation so thank goodness Bellwether took care of putting in all new insulation around the exterior of the entire house. Then, on to Phase 2, which I had to keep rescheduling with Katie at Bellwether because there were delays on a number of levels (none had to do with Bellwether) but Katie kept in contact with me and she kept moving the siding installation out until we were truly ready, we wanted to make sure we did this right so there were electrical delays and weather delays, you name it, but we kept in close communication with Bellwether, they were so patient with us, and finally 5 months after brick removal we were ready for siding. We had met with Dylan who was going to coordinate the application of the siding and Dylan was also amazing to work with, just like everyone else at Bellwether! I honestly can't say enough good things about these wonderful people and the company itself. You can see from the pictures what a big project it was and Bellwether stayed in contact with our deck contractor and us, and we all worked together to get it done. We are thrilled with the way it turned out!! If you need siding or windows call Bellwether first, don't even waste your time calling any other company. Bellwether Windows, Siding & Doors, is the BEST!!! We can't say enough good things about them. They took care of every concern or question we had and worked with us for 5 long months getting this project completed. Thank you all at Bellwether, we will always give you the best review and we will highly recommend you to everyone we come across!!!

We recently had new siding installed on our home by Bellwether, and the entire experience was outstanding from start to finish. Our sales rep, Seth Blue, did an excellent job understanding our goals and helping us choose the right siding to fit both our vision and budget. Dylan Harden, our Project Manager, made sure everything ran smoothly and kept us informed throughout the process. His crew lead, Julio, and the rest of the team worked with incredible attention to detail and took the time necessary to deliver a truly phenomenal result.

We couldn’t be happier with the finished product, and we’re very glad we made the right choice in going with Bellwether. I highly recommend them—you won’t regret it

Very talented crew with a impressive work ethic. Errors were caught early and quickly corrected. Very professional crew that worked together seamlessly. We ate happy with the new look. We would recommend Bellweather, in fact we are already telling our neighbors.

We are very happy with our new siding, front door and windows. A shout out to Laura, Cole and Angel for making our house look new again! All three were professional, knowledgeable and kind.

Everyone was so nice and personable. Dylan was a great project manager and communicated well. We love our new Hardie board siding and the look of our house.

Could not be happier with this company. Mike Sipes was incredibly patient and helpful, Cole did a fantastic job as managing everything, as did everyone in the office. And the windows and siding all look fantastic. We constantly get compliments from people passing by. Would 100% recommend.

We had a great experience with Bellwether from beginning to end. Dylan, Angel, and Amy were great to work with and ensured the project was completed on time and within budget! Would highly recommend them!

Bellwether did a fantastic job of replacing the side shingles that were original on our 130-year-old home. There were many extra steps to go through because it is on the historic registry, and they had to get as close as possible to like replace like with like and had to create renderings of what the new tiles would look like. Laura was the original project manager and she was knowledgeable and patient. Cole managed the crew and they were all respectful and left absolutely no mess. Katie was responsive with our questions and it was a delight to meet Amy, who came today to see the finished project. She was delightful and was most receptive to any input on improving their service. I highly recommend this company, especially if you have a historic home.

Working with this company has been wonderful - from the sales person Terri (amazing and delightful) - to the team that showed up and measured and communication on windows arriving to installation - Great job!

Great job! Huge thank you for the whole crew. Dave is a great and knowledgeable salesman, Cole our project manager was super responsive, Amy the designer came up with amazing colors and we are very satisfied, Karen the accountant is always in contact and never misses a message. Everything was very neat and organized. Everyone was very pleasant to work with. Thank you, Bellwether! I would recommend you to anyone who asks.

My experience with Bellwether was excellent. The staff was very professional and responsive to our requests. We worked with Dave Neuhausel, Cole Gulden, Angel (siding crew chief) and Amy Rust on this project. The project included replacement siding, soffits and fascia, and installation of new rain gutters. All work was done on schedule with excellent workmanship evident. A big thank you to all at Bellwether for a job well done.

Lauren, Karen, Cole and the entire gang worked with me from start to finish to make sure every detail came out just the way I wanted. I highly recommend Bellwether: they will take care of you and your project.

A few years ago we had siding put on and Bellwether was great so naturally when we needed to update some doors and put in a French door, we called on them again.
*Amy was great from start to finish making sure we were up to date on planning and getting everything we needed.
*Cole was great to work with throughout the whole process and really gave us a personal touch and made sure we got what we wanted.
*Luis and his crew made sure we knew about issues they ran into and worked hard to fix everything they found. They were respectful, professional, and did an amazing job.

I would suggest Bellwether to my family and friends, and we will use them again in the future.

From start to finish this company has its act together. We hired Bellwether after interviewing 3 other companies to replace vinyl siding which had been hail damaged. We are so glad that we picked Bellwether and James Hardie siding. Seth, came out to give an estimate and he brought all the color samples and gave a great presentation of the company, the product, and the process. He is meticulous, dedicated, informative, and not pushy at all. One of the other companies did not bring samples and another gave us an estimate that included work that we didn’t ask for, and another left out a lot of information that we had discussed. Seth was just right on and help guide us with color choice and materials. His estimate was meticulous and accurate to what we had talked about with him.
Dylan was the project manager and did a great job informing us of what was going to happen, when it was going to happen and to be a constant contact with company and its crew. We had a message number that we could contact him if something was happening at our home that we were concerned about. It was a convenient way to be heard right away.
Angel was the lead for the construction crew that came out to replace our siding and he was just fantastic! Don’t let how young he looks fool you because he is experienced, knowledgeable, sincere, kind & nice, and a hard worker along with all of his crew. They did a fantastic job and we are so happy with our house. It almost feels like we have a new home and we feel confident it can withstand some of the extreme weather we get here in Colorado.
We were having my husband’s 70th birthday party at our house in 3 weeks and they were able to work us in and get our whole house done within 3 days with a big crew. That was so helpful and relieved a lot of stress for us so that we could get everything back together before the party. Thank you so much for that part!
Just wanted to mention Katie, Karen, and Amy in the office, they were so nice and helpful going through the HOA process and the follow-up.
Thanks Bellwether - just love working with all of you and your company! Highly recommend this Bellwether for siding and gutters. Will definitely think about them for future work when we need it done right!

Bellwether did a James Hardie siding installation. From helping figure out design to communicating on pre-job walk through to getting the job done they did excellent. Their crews have a great eye and attention for detail. You can tell they install the siding to manufacturer specification and take pride in their work. Finally I found the project manager to really care about customer satisfaction - they made sure to take care of final little details to make sure the job was fully complete and done right. I woudl highly recommend. Thank you!

Bellwether was great about helping us evaluate options for a siding replacement and listening to our preferences on a desired product. Install went great and the project manager kept us updated with photos and texts throughout, and provided detailed answers to questions.

I was recommended to Bellwether from my family because I was impressed about the quality of Bellwether's work.

Fast forward 6 months later, and Bellwether did my house.. From start to finish, I wouldn't have it any other way. Travis Towers with Bellwether was so awesome, professional, and all around a friendly person. Karen in financing works with you financially from beginning to end.

Bellwether's prices are are so great, I ended up getting the fiber cement siding.

Project manager Dylan and Cole are so professional, prompted, and detailed oriented. Pretty cool guys too.

Overall, Bellwether's should be the 1st choice for ALL your home needs.

We were impressed with the Bellwether team. Seth was professional, understanding, and listened to our design questions and concerns. Dylan, Angel and the sixteen man crew met our goals and finished the siding in three days. The entire project schedule, from siding to gutter install, was executed as promised. We appreciate and believe the Bellwether process and highly recommend this family owned company!

Great experience beginning to end. Laura O., Dylan, Amy, and Angel really took care of us and got what we needed and wanted within a reasonable budget for the project. No complaints and would definitely recommend to friends and family.

We had our siding, soffits, fascia, and windows replaced by Bellwether and we could not be happier with the work or the customer service. The pricing was very comparable to other estimates we received, they outlined the process and even came out ahead of schedule. We were due to get a snowstorm when scheduled, and rather than cancel, they sent out two crews, over 15 people, to get the job done in a couple of days. I also very much appreciated the help with the design. Our house doesn't have much visual interest, and Bellwether made some suggestions that were awesome to take the look up a few notches (incorporating some cedar looking siding in with a darker tone). It turned out BEAUTIFULLY and we get compliments all the time. Neighbors liked the look so much that they had Bellwether come out to do their siding and windows a couple of months later. I can't recommend them enough!

We installed a new Sierra Pacific door and 3 Pelle windows in our Lennar house in the northend area. The process took around 3 months and we're super pleased with the quality and care towards making our vision into a beautiful reality. The design process was super smooth and gave us a lot of ideas to work with while considering the structural integrity and resell value. The actual work days where the house was in a mess was less than 6 days, but scheduling and holidays was a factor in making sure everything was fully addressed. We're 100% working with Josh and Tanisha (and their great contractors) again on future projects. I think their team enjoys unique projects like cutting wider openings for walls and solving harder problems than just replacing siding and installing windows. Extremely skilled professionals.

Our experience with Bellweather and having new windows installed has been awesome! From first contact with Seth our Project Guide who helped us determine what kind of windows and pricing would best fit our needs and budget; to then working with the Project Manager Dylan who prepped us on what to expect, scheduled all of the work, and walked with us through the entire process; to the installation team and their lead Angel, all of whom were extremely good at their work, very kind, respectful, and completely thorough; and to the folks behind the scenes, Katie who kept us in the loop with window and dumpster delivery, billing and more, and Karen who kept us square with permits and HOA approvals... everyone along the way was professional, kind, thorough, and communicative. Our new Pella windows make our home feel whole, and we can already feel the difference. My wife and I are very grateful to the good folks at Bellweather and whole heartedly recommend them for any siding or window project that you might be considering.

I had an excellent experience working with Bellwether! From the initial consultation with Seth to the final walkthrough with Dylan. The team was professional and efficient. The quality of their work exceeded my expectations, and they made sure to keep me informed throughout the entire process. The project was completed on time and within my budget, which I truly appreciated. I highly recommend Bellwether for anyone looking for reliable, high-quality window replacement, painting and construction services. Thank you to the entire team!

We were so impressed with Bellwether as they stood behind their work! Seth’s knowledge base on James Harding and siding install was evident after interviewing many companies. We did get off to a rocky start with a poor construction crew however Cole and Dylan listened to our concerns. They got in an amazing crew with Angel as the crew lead and the work was impeccable!!! Thank you Katie for following up. Again this is a great company who totally took care of us! We look forward to posting pics when we complete the landscaping!

Bellwether replaced the siding on my house. It was a complicated project but they did an excellent job. They were very responsive from beginning to end, with no drama and no surprises. I highly recommend them.

We had a great experience. We had our siding replaced. They had a huge crew and it was completed in 3 days! My wife and I were shocked how fast they went, they were working hard to get it done before a cold front came in.

The crew was great, cleaned up, and got the dumpster out quickly.

Having your siding replaced is very loud, so I would recommend planning to be out of the house for the first 2 days (or get some good ear plugs!)

Great experience, good pricing, great project manager and crews.

We recently got new windows and siding and absolutely love the outcome! The crew that came out was so fast and very nice/respectful!

My project was very unique. I only needed to replace my gables and side a shed to match. I had 5 different quotes and Bellwether was the only reasonable one that was eager to do the job. I couldn't be happier with how it came out. It was such a small 4-day project and they worked outside of their comfort zone on my unique shed situation (4 doors and swing-in window). Thank you so much for doing the great work at a reasonable price!

Josh and Tanisha run a tight ship. I’m pleased with their ability to get our project completed on budget and on schedule. We had a huge 18 unit siding replace of our townhomes and they were better than I could have expected. Trusting these guys was a great choice. Will do my work again and highly recommended!!

Bellwether Siding provided exceptional service. They replaced the siding on my home with impressive speed and maintained high-quality workmanship throughout the process. The team was courteous, and their follow-up was thorough, promptly addressing all minor concerns. I highly recommend them for any siding projects. Special thanks to David Dembiski for ensuring everything went smoothly.

The entire process, from proposal to completion, was a breeze. My home looks beautiful, and I am secure in knowing that the new siding installed by Bellwether is superior to the one it replaces.

Customer Service is Unbelievable. Let’s just say my job had challenges and Paul, Cole, and Karen didn’t give up until it was all done to my satisfaction. I just noticed, somehow one side of one window didn’t get caulked, I shared a picture with Cole (over a year after the initial completion) and he came out immediately and addressed the problem!

Over the top customer service is something most companies have forgot, but bellwether knows how to treat its customers!

I will plan to use bellwether again in the future, without any hesitation!

Thanks Again.

Bellwether did a great job of replacing the siding on our home with pre-primed Hardie board in Castle Pines. The siding looks perfect and the detailing was done with precision. We couldn't have been happier with the responsiveness of the company to any questions or concerns we might have and the crew worked well to complete the project in a timely fashion. It was a pleasure to work with the administrative staff, too. There was always a friendly and helpful voice on the other side of the line rather than a voice messaging or menu to scroll through . We highly recommend this family owned company to anyone looking for a siding replacement.

The most experienced and professional people in Colorado

Bellwether did a great job putting James Hardie siding on my cabin near Black Hawk. The crew worked quickly and took care of any issues. There were some issues with material delivery, but the PM took care of them and made sure a solution was figured out. Great work! I'm glad I chose to work with them.

Awesome staff super friendly helpful

We hired Bellwether to replace some old pine wood siding. They did an excellent job. Lee and Julio stood out as 2 employees that went above and beyond. They were very professional and a pleasure to work with.

Bellwether did an excellent job replacing the siding on our home with the James Hardie siding, from the beginning of the project to finish everyone was great.
Cash the salesperson was very polite and explained the how the process works,Lee came out prior to installation to let us know exactly what would be done during installation. Cole the project manager kept everything running smooth and kept me updated on the progress of the project. Angel the insallation crew leader was vey polite and made sure the job was done efficiently, the whole installation crew was very polite and kept things very neat.
All around Great customer service. I would highly recommend Bellwether.
If I could give 10 Stars I woud!!!

After going through the process of vetting several companies and receiving quotes for windows and siding, we decided to move forward with Bellwether. As you may have already figured out (if you're reading this you're likely shopping for a company), this process is not always the most pleasant as the companies vary greatly with the products they prefer, the prices can be drastically different even for the same products, and the overall feel of the representative that you're working with.

To begin with, getting an appointment with Bellwether was a breeze and speaking with them from the get go felt very professional and reassuring. I met with David from their sales team, and he got right to working with me to give me several iterations of what I wanted done, mostly based on different window choices. My one big ask of all the companies was to install new construction windows, rather than replacement type, since the siding would be coming off anyway. Much to my surprise Bellwether was one of maybe two companies that did not have an issue with this! Pricing was very competitive, and I really appreciated that they broke down all the costs in the quote, line by line. Whereas all the other companies gave you one number, not showing what cost what, Bellwether showed you all the minute details! Loved this, and made adjusting the work easier to meet budgets. Thanks, Dave.

Moving onto the work itself, I give much praise to Cole, Lee, Luis and his crew. Luis and his team did an amazing job with demolition, and installing the new construction windows, siding, and all the soffits and fascia boards. Their eye for details is the best; the caulking by the lady is some of the best I've ever seen and was highly admired by the neighbors! They showed up on time every morning and worked hard all day. The house wrap, siding, trim, etc. look amazing and the house already feels more efficient inside. The Pella windows are a huge change from the original 40yr windows and Bellwether was one of two that agreed to install them.

There were a couple of small hiccups that weren't the fault of Bellwether; the Pella rep mis-measured one of the windows so we had to wait on the replacement. However, they installed the too small window temporarily so that we had a window, and came back to finish the job once the window came in. Also had a mishap with the gutters but Tanisha was wonderful about it and fixed it right away.

Overall I am extremely pleased with how everything came out. It was a big job, but Bellwether came through and did a wonderful job with it. I am highly recommending them to my neighbors who are looking to have similar work done in the near future, and will surely use them again should the need arise

Thank you to everyone at Bellwether.

Great experience with Bellweather Windows and Siding. From start to finish everyone I worked with was super! I had James Hardie siding and 4 Pella replacement windows installed. Seth, the salesperson was friendly, informative and clearly explained the process. Cole, the project manager kept the operation running smoothly and kept me in the loop with the progress of the job. Julio, the head of the installation crew was incredibly diligent in making sure they all got the job done efficiently each day. Everyone was quick to respond with any questions I had throughout the installation. Highly recommend this company! Thrilled with the final outcome.

I've been thrilled with the service I've received from Bellwether. They did a beautiful job on my siding a couple years ago, and I've just now worked with them to replace my windows. Everyone involved with the company has been great to work with - polite, professional and thorough. One of the things that stood out to me is that I never had to remind anyone what color trim I had when I scheduled my window replacement, they knew what I had had done previously and ordered accordingly. They're very well organized and are good at staying in contact about the current state of projects.
