How Installing Energy-Efficient Windows in Hyattsville Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:

  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
  • Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Hyattsville

When looking into window installation, each company provides different services and costs. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

According to our research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These estimates are based on the specifics of your installation, such as type, material, the location of your home, number of windows, size and more.

Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with 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?

There are typically two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

Your window installation company should be able to help you choose what’s best for your needs. In Hyattsville, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if not maintained properly 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 Hyattsville

EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Hyattsville and assigned rankings based on the following methodology:

Service Area

Because this is a guide for Hyattsville, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Hyattsville.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

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 points 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 protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Hyattsville’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Hyattsville window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Hyattsville, MD Window Replacement FAQs

How much should a window install cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually 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 should I get?

A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or know-how, we recommend hiring a professional.

How often do you need to replace windows?

Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.

Should I replace my windows all at once?

If you’re upgrading your windows to get more efficient windows, replacing all of the windows at once is the only way to gain that benefit. However, if you have only a few windows that are broken or leaky, you can replace just those.
