How Installing Energy-Efficient Windows in Germantown Saves You Money

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

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if your home is on the older side.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Decrease your carbon footprint: In Germantown, you can lower your indirect greenhouse gas emissions by about 497 pounds per year once you upgrade to energy-efficient windows.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that amount, which helps you save some money on your bills.

Estimated Cost of Window Replacement in Germantown

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

How Much Do New Windows Cost?

Typically, Germantown homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost is based on several factors, such as size, type, the location of your home, number of windows, material and more.

Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $489 a year on your energy bills in Germantown.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.

Your window installation company should be able to help you decide which type of installation you need.

Service Area

Since this is a guide for Germantown, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Germantown.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. 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 online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of parts, professionalism, quality of installation, cost and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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