How Installing Energy-Efficient Windows in Amherst Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: In Amherst, you can reduce your indirect greenhouse gas emissions by about 65 pounds per year after you switch to energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Amherst
Each window replacement company provides various services and has varying costs depending on several factors.
How Much Do New Windows Cost?
Typically, Amherst homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These numbers vary based on the specifics of your installation, such as number of windows, type, material, the location of your home, size and more.
Keep in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that influences the overall cost is the material of the frame you choose. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the total window, including the sill, frame and trim. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Amherst, the choice will mostly depend on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Amherst
In our search to find the most reliable, eco-friendly window installers in Amherst, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve decided to review the top window installers in Amherst mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Amherst, we only included companies that serve the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Amherst.
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 featured on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Amherst’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Amherst window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Amherst, NY Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: picture windows, casement windows, double-hung and single-hung windows, slider windows, awning windows, transom windows and bay windows.
Can you replace your own windows?
While you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.
