How Installing Energy-Efficient Windows in Suitland Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
- Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Suitland
Each window installation company provides varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will make your project cost more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Suitland homeowners $283+ a year after replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. These installations are more involved and will increase the overall cost. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you choose what’s best for your needs. In Suitland, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Suitland
EcoWatch differs from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Suitland, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Suitland.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of installation, professionalism, quality of parts, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. 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.
Suitland, MD Window Replacement FAQs
How much should window installation cost?
The typical cost of installing one window can range between $450 and $650. There are several factors that influence the price, which include local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows and your property’s location.
What are the most common types of replacement windows?
There are several different kinds of windows you can get for your home, including slider windows, awning windows, double-hung and single-hung windows, picture windows, transom windows, bay windows and casement windows.
Do I really have to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best handled by the professionals.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace all my windows at once?
If you’re upgrading your windows to get more efficient windows, replacing all the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
