Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's efficiency can also have a considerable impact on home energy conservation. According to the Department of Energy, heat or cool air lost through old or damaged windows could be responsible for 25-30% of household energy climate control use.

That's also bad news for the environment because the extra energy required by leaky windows increases your carbon footprint.

Efficient windows are especially important in Glassmanor, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $283 a year.

How Installing Energy-Efficient Windows in Glassmanor Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 249 pounds.
  • 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.
  • Save on electricity bills: Since energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $283 annually on your energy bills in Glassmanor.

Estimated Cost of Window Replacement in Glassmanor

Let's go over the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, homeowners in Glassmanor can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at about $600. These amounts vary depending on specific characteristics of your installation, including size, type, the location of your home, material, number of windows and more.

Bear 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 you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall 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) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Glassmanor, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Glassmanor

In our search to find the most reliable, eco-friendly window installers in Glassmanor, EcoWatch evaluated dozens of companies before settling on these. We have assessed the top window replacement companies in Glassmanor mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand 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

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain installer, it won't be featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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

As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Glassmanor, MD Window Replacement FAQs

What is the average cost to replace windows?

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

What are the types of windows?

The most common types of windows for homes are picture windows, casement windows, bay windows, transom windows, awning windows, slider windows and double-hung and single-hung windows.

Can I replace my own windows?

While you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
