How Installing Energy-Efficient Windows in Orchard Park Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Save money on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In Orchard Park, you can lower your indirect greenhouse gas emissions by about 65 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in Orchard Park

When considering window installation, each company offers varying services and prices. Let's go over some typical costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Orchard Park can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. These estimates vary based on specific characteristics of your installation, such as type, number of windows, the location of your home, material, size and more.

It's important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Orchard Park homeowners $368+ a year when replacing single-pane windows.

Asking for free quotes from multiple companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations entail replacing the total window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. Full-frame installations are more involved and will raise the total cost. Pocket installations (or retrofits) involve installing a new window within the 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 should be able to help you figure out what's best for your needs. In Orchard Park, the decision will mostly depend on the age of your home 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 check on your frames and window sills.

How We Choose the Best Window Installers in Orchard Park

The EcoWatch Reviews team differs from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Orchard Park, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Orchard Park.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to ensure its contractors are well-qualified and that the company has received tons 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, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, warranty, cost, professionalism, quality of parts and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. 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 a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Orchard Park, NY Window Replacement FAQs

How much does window installation cost?

The average cost of installing a single window ranges between $450 and $650. There are several factors that affect the cost, such as how energy-efficient the windows are, the number of windows, the materials used in designing the windows, local labor costs, styles and sizes of windows and your property's location.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have 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 you replace your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or know-how, we don't recommend doing it on your own.

How do you know it's time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at the same time?

If your windows are more 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. Replacing your windows all at once will involve less paperwork and less stress.
