20 Best Window Companies in Katy, TX (2025 Reviews)

How Installing Energy-Efficient Windows in Katy Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, including:

• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 465 pounds per year on average.
• 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.
• 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.

Estimated Cost of Window Replacement in Katy

Each window installation company offers varying services and has varying prices depending on several factors.

How Much Do New Windows Cost?

According to our research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which carry a higher price tag.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

Something else that influences the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. So, instead of taking out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you understand what’s best for your needs. In Katy, the decision will mostly be based on how old your home is and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Katy

EcoWatch reviews differ from most reviews, as we examine these companies through a sustainability lens. We’ve reviewed the best window installation companies in Katy mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy 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 Katy, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Katy.

Work Quality

We’re willing to bet that you’re looking for professionals who 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 gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, warranty, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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