How Installing Energy-Efficient Windows in Tonawanda Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, such as:

• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Tonawanda, that’s about 65 pounds per year on average.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on power bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $368 annually on your energy bills in Tonawanda.

Estimated Cost of Window Replacement in Tonawanda

Let’s go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, Tonawanda homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs will differ significantly depending on the current condition of your home, the number of windows you need, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.

It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Tonawanda home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from several window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. These installations are more involved and will increase the overall cost. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

Your window installer can help you choose which type of installation you need.

How We Choose the Best Window Installers in Tonawanda

EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Tonawanda’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Tonawanda window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
