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

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
  • Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Fort Washington, that’s about 249 pounds per year on average.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Fort Washington

Each window replacement company provides varying services and has different prices depending on a few factors.

How Much Do New Windows Cost?

On average, homeowners in Fort Washington can expect that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. But costs will vary significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

Whether or not you want 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 Fort Washington.

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

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the frame, trim and sill. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

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 Fort Washington

EcoWatch reviews are different from other reviews because we assess these companies through a sustainability lens. We have decided to evaluate the best window replacement companies in Fort Washington primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty 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 best window installation company near you.

Work Quality

When selecting new windows, the quality and variety 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 rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive things to say about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you 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 proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Fort Washington, MD Window Replacement FAQs

What is the average cost to replace windows?

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

What type of window is the most energy-efficient?

A window’s energy efficiency is influenced by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

Window installers will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation more difficult.

How long does window installation usually take?

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