How Installing Energy-Efficient Windows in Greenlawn Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
• Reduce your carbon footprint: In Greenlawn, you can cut your indirect greenhouse gas emissions by about 307 pounds per year after you switch to energy-efficient windows.
• Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.

Estimated Cost of Window Replacement in Greenlawn

Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the typical costs and services that you can find from window installers.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. Costs will vary considerably depending on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when you install 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 of your frame. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re not sure which window installation service you should get, your installer can assist you. In general, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

Work Quality

We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
