How Installing Energy-Efficient Windows in Tonawanda Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Save money on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: In Tonawanda, you can lower your indirect greenhouse gas emissions by about 65 pounds per year after you install energy-efficient windows.
Estimated Cost of Window Replacement in Tonawanda
Windows come in varying purposes, styles and shapes, so costs and services will vary tremendously depending on several factors. Below, we describe the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Generally, Tonawanda homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at approximately $600. This is due to the fact that the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Tonawanda home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the frame, sill and trim. A pocket installation entails installing a new window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you need, you can talk to your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Tonawanda
EcoWatch is different from other reviewers because we evaluate 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
Since this is a guide for Tonawanda, we gave more points to companies that serve the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Tonawanda.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Tonawanda, NY Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
A window's energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installers cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
How often should you replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them looked at by an expert to see if they need any repairs or replacements.
