How Installing Energy-Efficient Windows in South Glens Falls Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- More efficient energy usage in your home: In South Glens Falls where the winters can be cold, energy-efficient windows decrease the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Reduce your carbon footprint: In South Glens Falls, you can cut your indirect greenhouse gas emissions by about 65 pounds per year when you upgrade to energy-efficient windows.
- Better temperature control in your home: Living in a warm city like South Glens Falls often means depending on your AC to keep your house cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
Estimated Cost of Window Replacement in South Glens Falls
Windows come in different shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
According to our market research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace 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.
We recommend requesting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. 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 deterioration, you may need a full-frame installation instead.
If you're unsure which window installation service you should get, your installer should be able to advise you. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

South Glens Falls, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window's energy efficiency depends on a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you install your own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
