How Installing Energy-Efficient Windows in Depew Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Reduce your carbon footprint: In Depew, you can lower your indirect greenhouse gas emissions by about 65 pounds per year after you switch to energy-efficient windows.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help lower that amount, which helps you save $368 a year on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Depew
Each window installer offers various services and has different costs depending on several factors.
How Much Do New Windows Cost?
On average, homeowners in Depew can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. But costs will vary considerably depending on the current condition of your home, the number of windows you need, the quality of your products and your location. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Depew homeowners $368+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the full window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable rot. These installations are more involved and will raise the overall cost. Pocket installations are simpler and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you’re still debating which type of installation to get, you can consult with your provider and get their advice. The choice mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Depew
EcoWatch reviews are different from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
Because this is a guide for Depew, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Depew.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Depew’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Depew window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Depew, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to install a window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common types of windows for homes are awning windows, double-hung and single-hung windows, casement windows, picture windows, transom windows, bay windows and slider windows.
Do I really have to use a window installation company?
Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring the pros. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. In addition, it shouldn’t be raining, because rain can make the installation more difficult.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
