How Installing Energy-Efficient Windows in Glenmont Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Glenmont, that’s about 234 pounds per year on average.
Estimated Cost of Window Replacement in Glenmont
When researching window installation, each company offers different services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including type, size, material, number of windows, the location of your home and more.
It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that switching out the windows on your Glenmont home can mean 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. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from several window installation companies to find the one that works best for you.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
If you’re still debating which type of installation you need, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Glenmont
EcoWatch differs from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Glenmont, we only included companies that serve the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Glenmont.
Work Quality
When choosing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, cost, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, 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. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Glenmont, MD Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually influenced by 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.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your house, such as transom windows, bay windows, casement windows, slider windows, double-hung and single-hung windows, awning windows and picture windows.
Can you install your own windows?
If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don’t have the time or know-how, we recommend hiring a professional.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
How long does window installation take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
