How Installing Energy-Efficient Windows in Mount Oliver Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could help you:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on energy bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $313 annually on your energy bills in Mount Oliver.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 467 pounds.
Estimated Cost of Window Replacement in Mount Oliver
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Even though the national average to install a single window is about $600, it can range anywhere from $200 to $1,200. These amounts are based on the specifics of your installation, like number of windows, material, size, the location of your home, type and more.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Mount Oliver homeowners $313+ a year when replacing single-pane windows.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the window installer 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 decide what's best for your needs. In Mount Oliver, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Mount Oliver
In our hunt to find the most reliable, eco-friendly window installers in Mount Oliver, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We've decided to evaluate the top window replacement companies in Mount Oliver mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Mount Oliver, we gave more points 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 Mount Oliver.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, cost, warranty and more.
Cost
Cheaper windows certainly don't 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. 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 Mount Oliver's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Mount Oliver window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Mount Oliver, PA Window Replacement FAQs
What is the average cost to install windows?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation companies cover the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.
How long does window installation typically take?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
What time of year is a good time to replace my windows?
Although you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, since rain can make the installation more difficult.
