Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for style or have old windows, windows play a crucial role in conserving electricity in your home. If your windows are outdated or drafty, you could be losing 25-30% of your home's heat or cool air right out of them.

That's also bad for the environment because the additional energy used by leaky windows increases your carbon footprint.

Efficient windows are particularly important in Severn, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $222 per year.

How Installing Energy-Efficient Windows in Severn Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could benefit you:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Severn

Windows come in various shapes, purposes and styles, so costs and services will differ considerably depending on your project. Below, we go over the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs differ remarkably depending 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 replacements, which will add extra costs to your project.

It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Severn homeowners $222+ a year when replacing single-pane windows.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with 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?

When it comes to window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. A pocket installation entails replacing a window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which type of window installation service you should get, your installer should be able to help you out. Generally, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Severn

EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. We've decided to assess the best window installation companies in Severn mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When it comes to new windows, the quality and variety 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 give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews 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 parts, cost, quality of installation, professionalism, warranty and more.

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 make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

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

Years of Experience

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

Severn, MD Window Replacement FAQs

How much does a window install cost?

The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind 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?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies provide?

Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.

Should I replace all my windows at once?

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