How Installing Energy-Efficient Windows in Overlea Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, 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.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Overlea, that’s about 249 pounds per year on average.
Estimated Cost of Window Replacement in Overlea
Windows come in different shapes, purposes and styles, so costs and services will vary greatly depending on your project. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, Overlea homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. But costs will vary considerably depending on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.
It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Overlea home translates to an average energy savings of $236 to $319 each 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from multiple window installation companies to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the frame that’s already there. So, instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to advise you on the best type for your project. In Overlea, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Overlea
EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave 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 be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Overlea’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Overlea window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Overlea, MD Window Replacement FAQs
How much should a window install cost?
The national average cost to install a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window’s energy efficiency is influenced by a variety 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?
Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to see if they need any repairs or replacements.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows at once is the only way to see a noticeable difference. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
