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.

Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's efficiency can also have a considerable impact on home energy conservation. If your house has old or damaged windows, your HVAC system could be working extra hard to heat or cool your home. This means higher electric bills.

That's also bad for the environment, as the additional energy used by outdated windows increases your carbon footprint.

Because windows have such a considerable impact on your home, picking the right company for you is a big decision to make. That's why the EcoWatch team has created this list of the best window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Havre de Grace Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:

  • 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 your furniture, carpet and other valuables from fading.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • More efficient energy usage in your home: Because the summers can get quite hot in Havre de Grace, homeowners usually depend on their air conditioner during that time. Energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your home cool.
  • Save money on energy bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.

Estimated Cost of Window Replacement in Havre de Grace

Windows come in varying shapes, styles and purposes, so costs and services will differ greatly based on your project. Below, we detail the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

Generally, homeowners in Havre de Grace can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs will differ significantly based on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

It's important to bear in mind that windows with the best 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 Havre de Grace homeowners $285+ a year when replacing single-pane windows.

We recommend requesting free quotes from several window installers to find the one that works best for you.

What Services do Window Installers Offer?

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

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you choose what's best for your needs. In Havre de Grace, the decision will mostly depend on the age of your windows 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 assess your frames and window sills.

How We Choose the Best Window Installers in Havre de Grace

EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. We've reviewed the best window replacement companies in Havre de Grace mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Havre de Grace, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Havre de Grace.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to ensure 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 trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

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 labor rank higher with EcoWatch.

Years of Experience

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

Havre de Grace, MD Window Replacement FAQs

How much should a window install cost?

The average cost of installing a window can range from $450 to $650. There are many factors that affect how much it costs, such as your property's location, local labor costs, the materials used in designing the windows, the number of windows, styles and sizes of windows and how energy-efficient the windows are.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

Do you really have to use a window installation company?

You should hire a window installation company whenever you need to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, as rain can make the installation more difficult.
