How Installing Energy-Efficient Windows in Slippery Rock Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Slippery Rock
Let's go over the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
On average, homeowners in Slippery Rock can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost you depends on several factors, like the location of your home, number of windows, material, type, size and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Slippery Rock homeowners $271+ per year after replacing single-pane windows.
Getting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because full-frame installations are more involved, they will raise the overall cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you decide what's best for your needs. In Slippery Rock, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Slippery Rock
In our hunt to find the most reliable, eco-friendly window installers in Slippery Rock, EcoWatch examined many companies before landing on these. Along with energy efficiency, we evaluated several window installers in Slippery Rock and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Slippery Rock, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Slippery Rock.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window 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
Customer feedback is another very important review factor. If the majority of customers don't have positive things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you 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 a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Slippery Rock, PA Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of replacing a single window can range from $450 to $650. There are a variety of factors that influence how much it costs, including local labor costs, how energy-efficient the windows are, the materials used in designing the windows, your property's location, the number of windows and styles and sizes of windows.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are transom windows, slider windows, double-hung and single-hung windows, awning windows, picture windows, bay windows and casement windows.
What do window installation companies do?
Window installation professionals go to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in an 8-hour work day.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
