How Installing Energy-Efficient Windows in Mclean Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Decrease your carbon footprint: In Mclean, you can reduce your indirect greenhouse gas emissions by about 376 pounds per year when you upgrade to energy-efficient windows.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Mclean

Each window installer provides varying services and has different costs based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Mclean can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. But costs vary 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, which carry a higher price tag.

It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Mclean homeowners $359+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company will be able to help you figure out what's best for your needs. In Mclean, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Mclean

In our search to find the most reliable, eco-friendly window installers in Mclean, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have reviewed the top window installation companies in Mclean primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower 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 Mclean, we gave more points to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Mclean.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

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 provide lengthy warranties for products, parts and installation (aka workmanship) 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 installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Mclean, VA Window Replacement FAQs

What is the average cost to install new windows in a home?

The average cost to install one window ranges between $450 and $650. There are many factors that influence the price, such as how energy-efficient the windows are, styles and sizes of windows, your property's location, local labor costs, the materials used in designing the windows and the number of windows.

What are the most common types of replacement windows?

The most common kinds of windows for homes are slider windows, casement windows, transom windows, bay windows, awning windows, double-hung and single-hung windows and picture windows.

Can you replace your own windows?

If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or skills, we don't recommend doing it on your own.

How long does it usually take to install windows?

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.

Should I replace all my windows at the same time?

If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
