How Installing Energy-Efficient Windows in South Portland Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could benefit you:

• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 163 pounds.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in South Portland

Windows come in varying shapes, styles and purposes, so costs and services will differ greatly depending on your project. Below, we describe the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Though the typical cost of installing one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including type, material, size, the location of your home, number of windows and more.

It’s also worth noting that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your South Portland home can mean an average energy savings of $236 to $319 each 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are solid 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?

When it comes to window replacements, there are generally two types that your provider will offer: full-frame and pocket installations.

Full-frame installations involve replacing the complete window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has significant rot or deterioration. These installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

If you’re unsure which window installation service you need, your installer should be able to help you out. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in South Portland

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the South Portland area so you can find the right window installation company near you.

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

This one is a give-and-take: as with other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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