How Installing Energy-Efficient Windows in Katy Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Reduce your carbon footprint: In Katy, you can cut your indirect greenhouse gas emissions by about 465 pounds per year when you upgrade to energy-efficient windows.
- Save money on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way.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 home if you decide to sell.
Estimated Cost of Window Replacement in Katy
Each window installer offers various services and has different prices depending on several factors.
How Much Do New Windows Cost?
On average, homeowners in Katy can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. Costs will differ significantly depending on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using 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?
The first step when considering a window installation is to decide whether you want a full-frame or pocket installation.
Full-frame installations entail replacing the complete window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable damage or rot. Full-frame installations are more involved and will raise the total cost. A pocket installation involves installing a new window within the old frame. This means instead of tearing out the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation to get, you can ask your installer and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Katy
EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Katy and ranked them based on the following methodology:
Service Area
Since this is a guide for Katy, we gave more points to companies that serve 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 Katy.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to 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 range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, 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.
Katy, TX Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes are awning windows, transom windows, double-hung and single-hung windows, casement windows, picture windows, slider windows and bay windows.
Can I install my own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it typically take to install windows?
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 have a lot of windows that must be installed.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
