How Installing Energy-Efficient Windows in Houston Saves You Money

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

• Reduce your carbon footprint: In Houston, you can cut your indirect greenhouse gas emissions by about 507 pounds per year when you install energy-efficient windows.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Houston

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

How Much Do New Windows Cost?

On average, Houston homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at approximately $600. Costs will vary considerably based on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.

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

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step of a window installation is to think about whether you want 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 can also involve other materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the old frame. So, instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Houston

EcoWatch reviews differ from other reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Houston area so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

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

Years of Experience

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