How Installing Energy-Efficient Windows in Lockport Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

  • Decrease your carbon footprint: In Lockport, you can lower your indirect greenhouse gas emissions by about 65 pounds per year when you switch to energy-efficient windows.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Lockport

Each window installer offers various services and has different prices based on several factors.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. These amounts are based on specific characteristics of your installation, such as number of windows, material, size, type, the location of your home and more.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $335 a year on your energy bills in Lockport.

Asking for free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which type of window installation service you should get, your installer can help you out. Typically, the choice is based on 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 Lockport

The EcoWatch Reviews team differs from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Lockport so you can find a quality window installation company near you.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured 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 determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Lockport’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lockport window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Lockport, NY Window Replacement FAQs

How much should a window install cost?

The average cost of replacing a window can range from $450 to $650. There are a variety of factors that influence the price, such as the number of windows, styles and sizes of windows, the materials used in designing the windows, your property’s location, how energy-efficient the windows are and local labor costs.

Which type of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

Although 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 guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace my windows all at once?

If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have only a few windows that are broken or leaky, you can replace just those.
