How Installing Energy-Efficient Windows in Langley Park Saves You Money

There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
• Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Langley Park

When researching window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Langley Park can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

Whether or not you choose 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 Langley Park.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer 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 cost the most 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 thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation entails replacing a window without replacing the frame. So, instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Langley Park

EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. We’ve evaluated the top window installation companies in Langley Park primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Langley Park, we only included companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Langley Park.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation 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

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that provide 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 been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
