How Installing Energy-Efficient Windows in Dunn Loring Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 376 pounds.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Dunn Loring

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

How Much Do New Windows Cost?

Typically, Dunn Loring homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. These amounts are based on specific characteristics of your installation, such as size, type, number of windows, the location of your home, material and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates 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 you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

We advise requesting free quotes from several window installers to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation involves replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window installation company will be able to recommend the best type for your project. In Dunn Loring, the decision will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Dunn Loring

In our hunt to make your home improvements easier and more eco-friendly in Dunn Loring, EcoWatch landed on the above companies as the top window installation companies in the city. We've reviewed the top window installers in Dunn Loring 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 lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Dunn Loring area so you can find the best window installation company near you.

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 company included in our guide to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, warranty, professionalism, quality of installation and more.

Cost

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

Warranty

As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Dunn Loring's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Dunn Loring window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Dunn Loring, VA Window Replacement FAQs

How much does window installation cost?

The national average cost of installing one window is about $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. 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 is the best?

A window's energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

What services do window installation companies do?

Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers 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 often do you need to replace your windows?

Windows generally last around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.

Should I replace my windows all at once?
