How Installing Energy-Efficient Windows in Gaithersburg Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Gaithersburg
When considering window installation, each company offers varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Though the typical cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, like size, material, type, number of windows, the location of your home and more.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you’re not sure which window installation service you need, your installer should be able to help you out. Typically, the decision is influenced by 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 Gaithersburg
EcoWatch reviews differ from most reviews, as we’re examining these companies through a sustainability lens. We’ve decided to evaluate the best window installation companies in Gaithersburg primarily 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 electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have positive feedback about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies are not going to 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
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that have 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 good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Gaithersburg, MD Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually influenced by the size of the window, the location of your property and the type and material of the window. 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 type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can you install your 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 know-how, we don’t recommend it.
