How Installing Energy-Efficient Windows in South Glens Falls Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to think about making the switch:
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 65 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in South Glens Falls
Each window installation company provides various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
Generally, homeowners in South Glens Falls can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. Costs will differ considerably based on your location, the current condition of your home, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your South Glens Falls home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, 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?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable rot. Because full-frame installations are more involved, they will increase overall costs. A pocket installation entails installing a new window within the old frame. So, instead of removing the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which window installation service you should get, your installer can help you out. Generally, the decision is influenced by 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 South Glens Falls
The EcoWatch Reviews team is different from most reviewers, as we evaluate these companies through a sustainability lens. We've assessed the top window replacement companies in South Glens Falls mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for South Glens Falls, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in South Glens Falls.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, warranty, quality of installation, cost, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to South Glens Falls' climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of South Glens Falls window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
South Glens Falls, NY Window Replacement FAQs
How much does a window install cost?
The typical cost of replacing one window can range from $450 to $650. There are several factors that influence the price, which include how energy-efficient the windows are, local labor costs, styles and sizes of windows, the number of windows, the materials used in designing the windows and your property's location.
What are the most common types of replacement windows?
There are several different types of windows you can get for your home, including slider windows, awning windows, casement windows, double-hung and single-hung windows, transom windows, picture windows and bay windows.
What do window installation companies do?
Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up after the installation. In addition, many companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
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. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
