How Installing Energy-Efficient Windows in Manassas Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Reduce your carbon footprint: In Manassas, you can cut your indirect greenhouse gas emissions by about 376 pounds per year once you switch to energy-efficient windows.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Installing energy-efficient windows can help reduce that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Manassas

When researching window installation, each company offers different services and prices. Let's look at some average costs and services.

How Much Do New Windows Cost?

Even though the national average to replace one window is about $600, it can range anywhere from $200 to $1,200. These amounts vary based on specific characteristics of your installation, such as number of windows, material, type, size, the location of your home 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 replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a window replacement is to clarify whether you need a full-frame or pocket installation.

Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the complete window, including the sill, trim and frame. A pocket installation means replacing a window without removing the entire frame, which tends to be cheaper than a full-frame installation.

If you're unsure which kind of window installation service you need, your installer can help you out. Generally, 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 Manassas

EcoWatch is different from other reviewers, as we examine these companies through a sustainability lens. We've evaluated the best window replacement companies in Manassas primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Manassas, we paid more attention to companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Manassas.

Work Quality

When it comes to new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that have 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 been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
