Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a large impact on home energy conservation. Drafty, leaky windows can cost you in energy bills. In fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Unlike other review sites, EcoWatch ranks window companies on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Weslaco Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Reduce your carbon footprint: In Weslaco, you can cut your indirect greenhouse gas emissions by about 507 pounds per year after you upgrade to energy-efficient windows.
- More efficient energy use in your household: In Weslaco where the summers can be pretty hot, energy-efficient windows decrease how much cool air is lost through your windows, making it easier to keep your house cool.
Estimated Cost of Window Replacement in Weslaco
Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you can find from window installation companies.
How Much Do New Windows Cost?
Although the typical to replace a single window is around $600, it can range from $200 to $1,200. Costs will differ significantly based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
It's also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Weslaco home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid 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?
When considering window replacements, there are typically two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves replacing a window within the existing frame. This means instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation you need, you can ask your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Weslaco
EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Weslaco, we paid more attention to companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Weslaco.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included on this list to make sure 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 online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure 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 to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies 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.
Weslaco, TX Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of installing a single window ranges from $450 to $650. There are several factors that affect the cost, which include the number of windows, your property's location, local labor costs, styles and sizes of windows, the materials used in designing the windows and how energy-efficient the windows are.
Which kind of window should I get?
A window's energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should use a window installation professional whenever you need to replace your windows. Installing windows is a involved process that can take a lot of time, so it's best left to the professionals.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation harder.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
