How Installing Energy-Efficient Windows in Colonie Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save about $392 annually on your energy bills in Colonie.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Colonie
Windows come in various styles, shapes and purposes, so costs and services will vary considerably based on your project. Below, we go over the average cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Though the typical cost to install a single window is around $600, it can range from $200 to $1,200. These amounts are based on the specifics of your installation, including material, size, number of windows, type, the location of your home and more.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re not sure which kind of window installation service you should get, your installer should be able to advise you. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Colonie
In our hunt to make your home improvements easier and more eco-friendly in Colonie, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Colonie, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Colonie.
Work Quality
We’re willing to bet 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 technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Colonie’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Colonie window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Colonie, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window’s energy efficiency depends on several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should hire a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best left to the professionals.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
How long does window installation take?
Because a window takes about 30 minutes to install, about 16 windows can be installed in a typical 8-hour work day.
