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?

On average, National Harbor homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost you depends on several factors, like size, number of windows, type, the location of your home, material and more.

The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide 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?

The first step when considering a window installation is to clarify whether you want a full-frame or pocket installation.

Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in National Harbor

In our hunt to find the most reliable, eco-friendly window installers in National Harbor, EcoWatch examined dozens of companies before landing on these. Along with energy efficiency, we analyzed several window installers in National Harbor and assigned rankings based on the following methodology:

Service Area

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

Work Quality

When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.

Cost

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

Warranty

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

Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
