What They Don’t Tell You

Most of your risk is in design & installation, not the product.

For example, James Hardie Fiber Cement Siding is the best siding product in the market. It’s beautiful, durable, moisture & pest resistant, and ideal for Colorado’s climate.

But if fiber cement siding is installed incorrectly, it will fail and is costly to fix. It takes experience and factory training to install siding, windows and doors correctly.

When it comes to exterior remodeling, the stakes are high – you need to partner with proven design and installation expert that can guide you to the best possible outcome for your project, and give you the best remodeling experience with customer service you deserve.

The best experience! I work in construction and I am sad to say that most folks these days do not take any ownership, pride or responsibility. You were the best part of our remodel and we will sing your praises to all. Thank you for rescuing our home! I wish everyone did business like Bellwether Homes.

Siding replacement was executed on time, on budget, and very professional work. Communication with the company was excellent. Any additional charges were properly discussed and documented, so no surprises. Installation crew was phenomenal. Detail-oriented and responsive, clean, organized and hardworking crew. Very happy with the results.

Maybe it’s true but maybe it isn’t.

One thing that sets Bellwether apart from other companies is that we do full and partial siding replacement.

Some companies claim that anything less than a spendy full replacement just isn’t worth their time. They think that’s just good, practical business sense.

But we’re more interested in building trust-based relationships with our customers than in cashing in on their misfortune.

If we can do a partial replacement for you if that would be sufficient to restore your home’s true beauty and value we’d be honored to have the opportunity.

Let’s say we only really need to replace one wall of siding. We’ll help you choose an outstanding product that will blend in with your remaining siding, fix any trim that needs repair, collaborate with roof, gutter, and window contractors to make the job seamless for you and paint everything so your home looks as fresh and beautiful as possible. And, if we can, even with a partial replacement we’ll make it look like that storm never happened.

One note: we keep our prices fair (and fairly low, in comparison with our competitors). Sometimes, even if you could “get by” with a partial replacement, at our prices it makes sense to do a full replacement – to increase your property value, to help you sell the home quickly, or just to go for the great new look you’ve always wanted.

But it’s rarely the “only” option.

Not with our values and commitment to helping people.

We do a lot of charity work but beyond that, we look to help the customers other companies can’t – or won’t – help.

We learned some valuable lessons from our previous experience, including our time serving our country in the U.S. military. One of those lessons is that there’s always room in the marketplace for a firm with great integrity and attention to detail. Service Before Self is a core value we picked up along the way, and we work hard to make that our firm’s central operating principle.

When you make the investment in full or partial siding replacement, you’re making the decision to enhance the value of your home and it will lead to a faster sale for a better price.

If your siding is damaged or worn, there’s a good chance you can get some help from your homeowner’s insurance. And if there’s a gap between what they’ll cover and what we’ll have to charge you for the project, we offer financing options at low interest rates to help with the difference.

We’re almost always able to come up with a plan that makes great sense and helps you pass the home you’ve loved to the next neighbors who’ll love it, complete with a fresh, warm new look and durable, long-lasting protection.

Not always.

First of all, it might be possible to make a dramatic improvement in your home’s look (and value) with a partial siding replacement, which could save you thousands of dollars. But some companies aren’t interested in doing partial replacements. We are, if it’s what serves the customer best and we do a lot of partial replacement projects.

Beyond that, not all companies in our industry have our dedication to truly helping people with their siding needs. We’ve heard a number of times from customers who told us other companies had quoted 30%, 40%, or even 50% more than we charged them for a similar (or better) siding installation project.

We make a good, honest living. We take care of our employees and our expert installation crews but we don’t need to put you in a hole to do that. We’re proud of one accomplishment above all others: our customers are thoroughly delighted with our work, and their five-star reviews on Google and GuildQuality to prove it.

Often, that is the case.

That’s why the professionals at Bellwether have worked hard to earn a coveted designation in our industry: we’re James Hardie Elite Preferred, which means we’ve proven we can do detail-oriented, thoroughly “done right” installations of the world’s finest fiber cement siding (manufactured by James Hardie).

And we do a lot of great projects with James Hardie fiber cement siding.

It’s quite common that our expert analysis of a customer’s situation will lead us to recommend James Hardie fiber cement siding. It really is a great option for Colorado homeowners. But for some projects, we’re happy to work with other high-quality products (such as LP SmartSide).

Whatever’s best for you. That’s what’s best for us.

We have various consumer refinancing options. Some of which will allow you to make no payments for the first 18-24 months! We understand that you may want to get a HELOC or find other ways to pay for this project. Talk to us about what you need and we can guide you through the best way to pay for this project.

We know how to help you pick the right windows and doors for your project. Our sales team is fresh off a trip to Pella, Iowa where we were able to tour the plant where Pella windows are manufactured! We can help you with the window manufacturers of your choice but we are very well versed in the Pella window lines. When it comes to doors, we can also talk with you about your options. We are a preferred ProVia dealer and help you design the door on the spot for you to see.

Our Bellwether team takes being from Colorado seriously. We were deeply affected when the Marshall Fires tore through a local Boulder community leaving nearly 1000 homes devastated. We have already helped dozens of families “harden” their homes from their selections of windows to choosing the fiber cement siding for their home. We have trained with industry’s leaders on safety, fire resistances, and burn rates to know how to guide you to the best home exterior to protect your family.

We’re always ready to help? Give us a call. We’d love to chat with you, and to help you learn everything you can in order to make the most informed decision for your home and situation.
