Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. If you have traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means higher electric bills.
Installing new, efficient windows on your home can help you save money every month on your power bills — and you can help the environment as well.
We've put together a guide on the best installation companies to help you in your search, 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 Fulton Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 249 pounds per year on average.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $289 annually on your energy bills in Fulton.
Estimated Cost of Window Replacement in Fulton
Each window installer offers various services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. These amounts are based on specific characteristics of your installation, like size, type, number of windows, the location of your home, material and more.
It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Fulton home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When considering window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're not sure which window installation service you should get, your installer should be able to advise you. Typically, the decision depends 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 Fulton
The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. We've reviewed the top window installers in Fulton mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Fulton, we only included companies that cover the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Fulton.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the most quality service. Still, we want to make sure we're highlighting companies that offer a spectrum 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
Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Fulton, MD Window Replacement FAQs
How much should a window install cost?
The national average cost to install one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: double-hung and single-hung windows, bay windows, slider windows, awning windows, picture windows, casement windows and transom windows.
Can I replace my own windows?
Even though you can install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it typically take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
