How Installing Energy-Efficient Windows in Lansdowne Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

• Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $316 annually on your energy bills in Lansdowne.
• Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Lansdowne

Windows come in different shapes, styles and purposes, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

According to our research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost is based on several factors, like material, the location of your home, type, size, number of windows and more.

It’s also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Lansdowne home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a 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.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails installing a new window within the frame that’s already there. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Lansdowne

The EcoWatch Reviews team differs from other reviewers, as we’re examining these companies through a sustainability lens. We’ve reviewed the best window installation companies in Lansdowne primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality 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 featured in our guide 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 Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Because of Lansdowne’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Lansdowne window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
