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 Traditional, outdated windows can cost you in electric bills.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

By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:

  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $283 annually on your energy bills in Lanham.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Lanham

When considering window installation, each company provides varying services and prices. Let’s go over some typical costs and services.

How Much Do New Windows Cost?

Generally, Lanham homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost is based on several factors, like material, the location of your home, type, size, number of windows and more.

Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $283 a year on your energy bills in Lanham.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide 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 provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

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

In our hunt to find the most reliable, eco-friendly window installers in Lanham, the EcoWatch Reviews team assessed many companies before landing on these. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Lanham so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Lanham, MD Window Replacement FAQs

How much should window installation cost?

The average cost to replace a window can range between $450 and $650. There are many factors that influence how much it costs, including your property’s location, styles and sizes of windows, the materials used in designing the windows, the number of windows, how energy-efficient the windows are and local labor costs.

Which kind 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 that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

How often do you need to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
