Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s energy efficiency can also have a large impact on home energy conservation. Drafty windows can make your AC or heater work extra hard in the summer or winter.

That’s also bad news for the environment because the additional energy used by outdated windows increases your carbon footprint.

Unlike other sites, EcoWatch ranks window installation companies on energy efficiency while also balancing cost, customer satisfaction and service area.

Lower Merion Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Lower Merion, PA using our customized window cost calculator.

Estimated Window Cost:

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

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

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
  • Save money on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $312 annually on your energy bills in Lower Merion.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Lower Merion, that’s about 286 pounds per year on average.

Estimated Cost of Window Replacement in Lower Merion

When looking into window installation, each company offers varying services and costs. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Although the typical cost to replace a single window is about $600, it can range anywhere from $200 to $1,200. These amounts vary based on specific characteristics of your installation, including number of windows, size, material, the location of your home, type and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lower Merion homeowners $312+ each year after replacing single-pane windows.

Getting free quotes from multiple companies is the best way to find out which one is right for you.

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 trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Because these installations are more involved, they will raise the overall cost. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Lower Merion, the choice will mostly depend on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Lower Merion

EcoWatch reviews differ from other reviews since we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

Because this is a guide for Lower Merion, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Lower Merion.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have nice feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Because of Lower Merion’s climate, homeowners need to be wary of 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.

Lower Merion, PA Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, based on several factors. The price is generally dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What type of window is the best for energy efficiency?

A window’s energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window installation companies do?

Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

How often should you replace windows?

Windows usually last about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.

Should I replace all my windows at once?

If your windows are more than 20 years old, it’s probably time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
