How Installing Energy-Efficient Windows in Clinton Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Save money on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $283 annually on your energy bills in Clinton.
- Decrease your carbon footprint: In Clinton, you can reduce your indirect greenhouse gas emissions by about 249 pounds per year after you upgrade to energy-efficient windows.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Clinton
Let’s go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, Clinton homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
It’s also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Clinton home translates to 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step of a window installation is to figure out whether you need a full-frame or pocket installation.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window 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 without taking out the entire frame, which tends to be less expensive than a full-frame installation.
Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Clinton
The EcoWatch Reviews team differs from other reviewers since we’re examining these companies through a sustainability lens. We’ve reviewed the best window installers in Clinton mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Clinton, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Clinton.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Clinton’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Clinton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Clinton, MD Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complex process that can be difficult and time-consuming, so it’s best handled by the professionals.
How often do you need to replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
