Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. Traditional or damaged windows can cost you in electricity bills. In fact, the Department of Energy estimates that about 30% of your house's heat or cool air could be lost through your windows.
That's also bad news for the environment because the extra energy required by leaky windows increases your carbon footprint.
We've compiled a guide on the best installation companies to help you in your research, so you can not only take advantage of brand new windows, but also save money on your power bills.

How Installing Energy-Efficient Windows in Thurmont Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- More efficient energy usage in your home: In Thurmont where the winters can get very cold, energy-efficient windows cut back on how much heat is lost through your windows, which makes it easier to keep your home warm.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save money on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
Estimated Cost of Window Replacement in Thurmont
Windows come in varying shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But costs will vary significantly based on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $294 a year on your energy bills in Thurmont.
We advise requesting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the entire window, including the trim, sill and frame. Pocket installations are on the simpler end and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
If you're unsure which type of window installation service you need, your installer should be able to advise you. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Thurmont
EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. Along with energy efficiency, we analyzed 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 the Thurmont area so you can find the right window installation company near you.
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 company in our guide to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of installation, quality of parts, warranty, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Thurmont's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Thurmont window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Thurmont, MD Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your house, including casement windows, bay windows, slider windows, transom windows, double-hung and single-hung windows, picture windows and awning windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring a professional. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
How long does it typically take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
