How Installing Energy-Efficient Windows in National Harbor Saves You Money

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

  • Save on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $283 annually on your energy bills in National Harbor.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In National Harbor, you can cut your indirect greenhouse gas emissions by about 249 pounds per year when you switch to energy-efficient windows.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in National Harbor

Let's take a look at the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which carry a higher price tag.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save National Harbor homeowners $283+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window without removing the whole frame, which is usually less expensive than a full-frame installation.

Your window installation company can recommend the best type for your project. In National Harbor, the decision will mostly depend on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in National Harbor

EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed 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 the National Harbor area so you can find the right window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to 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, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

National Harbor, MD Window Replacement FAQs

What is the typical cost to replace windows in a home?

The average cost to replace a window can range from $450 to $650. There are a variety of factors that influence the cost, which include the number of windows, your property's location, the materials used in designing the windows, local labor costs, how energy-efficient the windows are and styles and sizes of windows.

What are the kinds of windows?

There are various types of windows you can get for your home, including casement windows, bay windows, slider windows, picture windows, double-hung and single-hung windows, awning windows and transom windows.

When do I have to use a window installation company?

You should hire a window installation professional whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.

What time of year should I replace my windows?

While you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.

How often do you need to replace your windows?

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