How Installing Energy-Efficient Windows in Langley Park Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- More efficient energy usage in your household: Because the winters can get very cold in Langley Park, homeowners usually depend on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your house warm.
Estimated Cost of Window Replacement in Langley Park
When considering window installation, each company offers different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
Typically, Langley Park homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. These estimates are based on specific characteristics of your installation, including size, number of windows, type, the location of your home, material and more.
Keep in mind that energy-efficient windows may cost more upfront, 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. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from several providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which kind of window installation service you should get, your installer can advise you. Typically, the choice is based 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 Langley Park
In our hunt to find the most reliable, eco-friendly window installers in Langley Park, the EcoWatch Reviews team assessed many companies before deciding on these. We've reviewed the top window installation companies in Langley Park mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) 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 will earn higher rankings by our standards. We like to see at least ten years of experience.
Langley Park, MD Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
There are various kinds of windows you can get for your home, such as slider windows, double-hung and single-hung windows, transom windows, awning windows, casement windows, bay windows and picture windows.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
What time of year should I replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. 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 isn't necessarily a big factor. Most importantly, the weather should be dry.
