How Installing Energy-Efficient Windows in Loudoun Valley Estates Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $353 annually on your energy bills in Loudoun Valley Estates.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Decrease your carbon footprint: In Loudoun Valley Estates, you can cut your indirect greenhouse gas emissions by about 376 pounds per year when you switch to energy-efficient windows.
Estimated Cost of Window Replacement in Loudoun Valley Estates
When researching window installation, each company offers different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
Though the national average to replace one window is around $600, it can range from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.
It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Loudoun Valley Estates homeowners $353+ a year when replacing single-pane windows.
Requesting free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when planning an installation is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Loudoun Valley Estates
In our hunt to make your home improvements easier and more eco-friendly in Loudoun Valley Estates, EcoWatch chose the above companies as the best window installation companies in the city. We have evaluated the top window installation companies in Loudoun Valley Estates 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 cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers 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 best window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that offer a wide range 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 that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. 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.
Loudoun Valley Estates, VA Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
There are several different types of windows you can get for your house, such as bay windows, picture windows, double-hung and single-hung windows, slider windows, transom windows, casement windows and awning windows.
What do window installers do?
Window installers visit your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does window installation generally take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
