- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in King of Prussia
Windows come in varying shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you’ll find from window installers.
How Much Do New Windows Cost?
According to our market research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These figures are based on the specifics of your installation, including size, the location of your home, number of windows, material, type and more.
It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save King of Prussia homeowners $312+ a year when replacing single-pane windows.
Getting free quotes from multiple providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire 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 involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
Your window installation company will be able to help you understand what’s best for your needs. In King of Prussia, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in King of Prussia
In our search to make your home improvements easier and more eco-friendly in King of Prussia, the EcoWatch Reviews team evaluated many companies before deciding on these. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
Because this is a guide for King of Prussia, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in King of Prussia.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including warranty, cost, professionalism, quality of installation, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to King of Prussia’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of King of Prussia window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
King of Prussia, PA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost to replace a window can range from $450 to $650. There are a variety of factors that influence the cost, such as the materials used in designing the windows, styles and sizes of windows, local labor costs, your property’s location, how energy-efficient the windows are and the number of windows.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace my windows all at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
