How Installing Energy-Efficient Windows in Lower Merion Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, including:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 286 pounds per year on average.

Estimated Cost of Window Replacement in Lower Merion

Let’s take a look at the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Typically, Lower Merion homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. But costs vary 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 and replacements, which carry a higher price tag.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide 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?

There are generally two types of window installation services: 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 new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

If you’re still debating which kind of installation you need, you can talk to your installer and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Lower Merion

EcoWatch reviews differ from most reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Lower Merion area so you can find a quality window installation company near you.

Work Quality

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

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most 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 warranty, cost, professionalism, quality of parts, quality of installation and more.

Cost

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

Warranty

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

Years of Experience

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