How Installing Energy-Efficient Windows in Fort Washington Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:

  • Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
  • 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 fading of your furniture, carpet and other valuables.
  • Save money on energy bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save about $283 annually on your energy bills in Fort Washington.
  • Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 249 pounds.

Estimated Cost of Window Replacement in Fort Washington

When considering window installation, each company offers varying services and costs. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range from $200 to $1,200. These numbers are based on specific characteristics of your installation, such as type, the location of your home, material, size, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Fort Washington homeowners $283+ per year after replacing single-pane windows.

We recommend requesting free quotes from several window companies to find the one that works best for your budget.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler 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 installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Fort Washington

The EcoWatch Reviews team is different from other reviewers since we look at these companies through a sustainability lens. We've assessed the top window installation companies in Fort Washington mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve the Fort Washington area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

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

Fort Washington, MD Window Replacement FAQs

How much does a window install cost?

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

What are the most common types of replacement windows?

The most common kinds of windows for homes are casement windows, transom windows, slider windows, awning windows, bay windows, picture windows and double-hung and single-hung windows.

What services do window replacement companies provide?

Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How long does window installation take?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
