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 doing home renovations or have old windows, windows play a key role in conserving electricity in your home. Traditional, outdated windows can cost you in electric bills. In fact, the Department of Energy estimates that about 30% of your house’s heat or cool air could be lost through your windows.

That’s not great for either your wallet or the environment, but one of the best window installation companies can help you with that.

Unlike other review sites, EcoWatch ranks window installation companies based on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Lanham Saves You Money

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

  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Lanham

Windows come in various styles, purposes and shapes, so costs and services will vary greatly based on several factors. Below, we describe the average cost and services that you’ll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs differ considerably 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 offer door replacements, which will make your project cost more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your installers will replace the entire window, including the sill, trim and frame. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Lanham

In our hunt to find the most reliable, eco-friendly window installers in Lanham, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have reviewed the best window replacement companies in Lanham primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Lanham, we only included companies that serve the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Lanham.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most 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 warranty, professionalism, cost, quality of installation, quality of parts and more.

Cost

This one is a give-and-take: as with other services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with 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 a good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Lanham, MD Window Replacement FAQs

What is the typical cost to replace windows?

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

What kind of window is the best for energy efficiency?

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 — this means they’re certified energy-efficient by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and know how to replace a window, it’s possible to install your own windows. However, if you don’t have the time or skills, we don’t recommend it.

How often do you need to replace windows?

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

How long does it generally take to install windows?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
