Why you can trust EcoWatch
Whether you're updating for aesthetics or have windows that need repairs, windows play a important role in conserving your home's energy. Drafty windows can reduce your home's energy efficiency by up to 30%, according to the Department of Energy. In Louisville, that's almost $457 per year that you could save on your electricity bills after making the switch.
That's also bad for the environment because the extra energy required by leaky windows increases your carbon footprint.
As windows have such a great impact on your home, picking the best company for you is a big choice to make. That's why the EcoWatch team has put together this list of the top window installation companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Louisville Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:
- Reduce your carbon footprint: In Louisville, you can lower your indirect greenhouse gas emissions by about 460 pounds per year once you switch to energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $457 annually on your energy bills in Louisville.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Louisville
Windows come in varying purposes, shapes and styles, so costs and services will differ remarkably based on several factors. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Although the national average to replace a single window is about $600, it can range from $200 to $1,200. These estimates vary based on specific characteristics of your installation, such as material, the location of your home, type, size, number of windows and more.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Louisville homeowners $457+ a year when replacing single-pane windows.
Costs will also vary depending on the material you want for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall 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 within the existing frame, which is usually cheaper than a full-frame installation.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Louisville, the decision will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Louisville
In our hunt to find the most reliable, eco-friendly window installers in Louisville, EcoWatch landed on the above companies as the top window installation companies in the city. We have assessed the best window installation companies in Louisville mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Louisville, we only included companies that cover the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Louisville.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to ensure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. Still, we want to ensure 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Louisville's climate, homeowners will want to mitigate low efficiency, water damage and rot. 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.
Louisville, CO Window Replacement FAQs
What is the average cost to install windows?
The national average cost of installing a window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the different types of windows?
There are various kinds of windows you can get for your house, including picture windows, casement windows, slider windows, bay windows, awning windows, transom windows and double-hung and single-hung windows.
What do window installation companies do?
Window installation professionals go to your home 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.
How long does window installation usually take?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How often do you need to replace your windows?
Windows have a typical 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 operate, they may be in need of replacement.
