How Installing Energy-Efficient Windows in King Of Prussia Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in King Of Prussia
Let's take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. But costs will differ significantly based on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
It's important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save King Of Prussia homeowners $308+ a year when replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step when planning a replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you decide what's best for your needs. In King Of Prussia, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in King Of Prussia
In our hunt to find the most reliable, eco-friendly window installers in King Of Prussia, the EcoWatch team landed on the above companies as the best window installation companies in the city. We've evaluated the best window installers in King Of Prussia mostly 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 energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for King Of Prussia, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in King Of Prussia.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide 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 patterns in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of parts, professionalism, quality of installation, warranty 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 variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of King Of Prussia's climate, homeowners need to be wary of water damage, rot and low efficiency. 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
How much does window installation cost?
The average cost to install a single window ranges from $450 to $650. There are many factors that affect how much it costs, such as local labor costs, the materials used in designing the windows, the number of windows, how energy-efficient the windows are, styles and sizes of windows and your property's location.
What are the types of windows?
The most common types of windows for homes are awning windows, transom windows, picture windows, double-hung and single-hung windows, casement windows, slider windows and bay windows.
What services do window replacement companies offer?
Window installation professionals visit your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does it generally take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
