How Installing Energy-Efficient Windows in Frederick Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could help you:

  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your home.
  • More efficient energy usage in your household: Because the winters can get very cold in Frederick, homeowners often rely on their heater during that time. Energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your house warm.

Estimated Cost of Window Replacement in Frederick

Each window replacement company offers varying services and has varying price points depending on a few factors.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. But costs differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Frederick homeowners $294+ a year when replacing single-pane windows.

Something else that influences the overall cost is the material you pick for your frame. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

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

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Frederick's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Frederick window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Frederick, MD Window Replacement FAQs

How much does a window install cost?

The typical cost of replacing one window ranges from $450 to $650. There are many factors that influence how much it costs, such as the number of windows, your property's location, local labor costs, how energy-efficient the windows are, styles and sizes of windows and the materials used in designing the windows.

What are the most common types of replacement windows?

There are various types of windows you can get for your house, including casement windows, slider windows, transom windows, picture windows, awning windows, double-hung and single-hung windows and bay windows.

Can I install my own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or experience, we don't recommend trying it.

How long does it usually take to install windows?

Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
