How Installing Energy-Efficient Windows in Sterling Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in Sterling
Each window replacement company offers various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But costs will differ considerably based on the number of windows you need, the current condition of your home, your location and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. Additional services will increase overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Sterling home can mean 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 installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you're not sure which kind of window installation service you should get, your installer should be able to advise you. In general, 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 Sterling
In our search to find the most reliable, eco-friendly window installers in Sterling, EcoWatch chose the above companies as the top window installation companies in the city. We have assessed the best window installers in Sterling mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Sterling, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Sterling.
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 included in our guide to make sure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Sterling, VA Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window should I get?
A window's energy efficiency is affected by several factors, including 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 since they are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complicated 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 company is a faster, more efficient and safer option.
How do you know it's time to replace your 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. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
