20 Best Window Companies in Louisville, KY (2025 Reviews)

How Installing Energy-Efficient Windows in Louisville Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:

• Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
• Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Louisville

Each window installation company offers varying services and has different prices depending on a few factors.

How Much Do New Windows Cost?

Though the typical cost of replacing one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, including number of windows, type, size, the location of your home, material and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Louisville homeowners $321+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like 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 around the window after a full-frame installation. A pocket installation means replacing a window without taking out the whole frame, which is usually less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Louisville, the choice will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Louisville

EcoWatch differs from other reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Louisville, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Louisville.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, warranty, professionalism, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that offer 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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