How Installing Energy-Efficient Windows in Frederick Saves You Money

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

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Frederick, that's about 460 pounds per year on average.
  • Save on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $457 annually on your energy bills in Frederick.
  • 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Frederick

Windows come in various shapes, purposes and styles, so costs and services will vary remarkably based on several factors. Below, we detail the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Even though the average of installing one window is about $600, it can range from $200 to $1,200. How much it will cost you varies based on several factors, like type, material, number of windows, size, the location of your home and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive 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 step of a window installation is to decide whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall 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. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.

Your window replacement company should be able to help you choose what's best for your needs. In Frederick, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess 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, EcoWatch evaluated many companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

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

Work Quality

When picking new windows, the quality and breadth 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

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, cost, warranty, quality of parts and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded 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 that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. 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.
