How Installing Energy-Efficient Windows in Olean Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Olean
Let’s go over the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, Olean homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $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 companies also offer door installations and replacements, which have a higher price tag.
It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Olean homeowners $414+ a year when replacing single-pane windows.
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?
The first thing to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable deterioration. Because these installations are more involved, they will raise overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re not sure which type of window installation service you need, your installer should be able to help you out. Generally, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Olean
EcoWatch reviews differ from other reviews, as we evaluate these companies through a sustainability lens. We have evaluated the top window installers in Olean mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, quality of installation, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, 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. That’s why window installation companies that provide 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 quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
