How Installing Energy-Efficient Windows in Colesville 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:

• Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• 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 about $294 annually on your energy bills in Colesville.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Colesville

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?

Generally, Colesville homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. These estimates are based on the specifics of your installation, such as number of windows, the location of your home, type, size, material and more.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Colesville homeowners $294+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because these installations are more involved, they will increase the total cost. 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 most likely need a full-frame installation instead.

Your window replacement company should be able to help you decide what’s best for your needs. In Colesville, the decision will mostly depend on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.
