How Installing Energy-Efficient Windows in Friendly Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Friendly, that's about 249 pounds per year on average.

Estimated Cost of Window Replacement in Friendly

Let's take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Though the typical to replace a single window is around $600, it can range from $200 to $1,200. But prices 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 make your project cost more.

It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Friendly home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are solid 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?

When considering window installations, there are generally two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you're still debating which kind of installation to get, you can consult with your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Friendly

EcoWatch is different from other reviewers since we assess these companies through a sustainability lens. We've assessed the top window installers in Friendly primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers more points 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 good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Friendly, MD Window Replacement FAQs

How much should a window install cost?

The average cost to install a single window can range from $450 to $650. There are several factors that influence the cost, which include how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, local labor costs, your property's location and the number of windows.

Which kind of window is the best?

A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Can I replace my own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or experience, we recommend getting a professional to do it for you.

What time of year should I replace my 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, because rain can make the installation harder.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
