How Installing Energy-Efficient Windows in Clarksburg Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 364 pounds per year on average.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Save on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $294 annually on your energy bills in Clarksburg.
- 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Clarksburg
When researching window installation, each company offers varying services and prices. Let’s go over some average costs and services.
How Much Do New Windows Cost?
According to our market research, the typical cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. But prices differ considerably depending 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 replacements, which have a higher price tag.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Clarksburg homeowners $294+ per year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, there are generally two types that your installer will have: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Clarksburg
In our search to make your home improvements easier and more eco-friendly in Clarksburg, EcoWatch assessed many companies before landing on these. We have evaluated the top window replacement companies in Clarksburg mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can 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 Clarksburg, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Clarksburg.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of 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 warranty, professionalism, cost, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, 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 been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Clarksburg, MD Window Replacement FAQs
How much should window installation cost?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window’s energy efficiency is influenced by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or experience, we recommend hiring a professional.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
Should I replace my windows all at the same time?
If you’re upgrading your windows to save on your energy bills, replacing all the windows at once is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
