How Installing Energy-Efficient Windows in Frederick Saves You Money

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

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $294 a year on your bills.

Estimated Cost of Window Replacement in Frederick

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

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. These numbers vary depending on specific characteristics of your installation, like number of windows, type, size, material, the location of your home and more.

It's also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your Frederick home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step when considering a window installation is to figure out whether you need a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end 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 will be able to help you choose what's best for your needs. In Frederick, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Frederick

In our hunt to find the most reliable, eco-friendly window installers in Frederick, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

Because this is a guide for Frederick, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Frederick.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you opt for. 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 nice things to say about their service from a certain installer, it won't be featured on EcoWatch.

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 providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty
