How Installing Energy-Efficient Windows in Clay Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- More efficient energy usage in your household: Because the summers can get quite hot in Clay, homeowners often depend on their air conditioner during that time. Energy-efficient windows decrease the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 286 pounds.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Save on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save around $308 annually on your energy bills in Clay.
Estimated Cost of Window Replacement in Clay
Windows come in different styles, shapes and purposes, so costs and services will differ tremendously based on your project. Below, we detail the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Generally, Clay homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at around $600. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will make your project cost more.
Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $308 a year on your energy bills in Clay.
Requesting free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable deterioration. Full-frame installations are more involved and will raise overall costs. A pocket installation involves replacing a window within the existing frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation you need, you can talk to 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 Clay
The EcoWatch Reviews team differs from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Clay and assigned rankings using the following methodology:
Service Area
Because this is a guide for Clay, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Clay.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. 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 trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't 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 gave higher scores 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Clay, PA Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
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, slider windows, bay windows and casement windows.
Can I replace my own windows?
While it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How long does window installation generally take?
Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
