Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through outdated or drafty windows could be responsible for close to 30% of heating and cooling use. In Lower Merion, where the energy bills are an average of $36 per month, that's almost $$127 per year wasted.
That's not great for your bank account or the environment, but one of the best window installation companies can help you with that.
Efficient windows are especially important in Lower Merion, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $312 a year.

How Installing Energy-Efficient Windows in Lower Merion Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Save on electricity bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $312 annually on your energy bills in Lower Merion.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Reduce your carbon footprint: In Lower Merion, you can lower your indirect greenhouse gas emissions by about 286 pounds per year when you install energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Lower Merion
When considering window installation, each company provides varying services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
Although the national average to replace a single window is about $600, it can range anywhere from $200 to $1,200. How much it will cost you varies based on several factors, like size, material, the location of your home, number of windows, type and more.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $312 a year on your energy bills in Lower Merion.
Asking for free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still trying to decide which type of installation you should get, you can ask your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Lower Merion
In our search to make your home improvements easier and more eco-friendly in Lower Merion, EcoWatch assessed dozens of companies before landing on these. We've reviewed the best window replacement companies in Lower Merion mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Lower Merion, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Lower Merion.
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 on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends 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 nearly every category, including warranty, quality of installation, quality of parts, professionalism, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won't always provide the most quality service. Still, 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
As discussed, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Lower Merion's climate, homeowners need to be wary of water damage, rot 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
What is the typical cost to install windows in a home?
The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence the cost, which include your property's location, the materials used in designing the windows, local labor costs, styles and sizes of windows, the number of windows and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.
