Why you can trust EcoWatch

How Installing Energy-Efficient Windows in Weslaco Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 507 pounds.
Estimated Cost of Window Replacement in Weslaco
Windows come in varying styles, shapes and purposes, so costs and services will differ tremendously based on your project. Below, we detail the typical cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
Although the average cost to install one window is about $600, it can range anywhere from $200 to $1,200. But costs will differ considerably based on the current condition of your home, your location, the number of windows you need and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
Bear 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 install single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
We recommend requesting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will raise the overall cost. A pocket installation involves installing a new window within the existing frame. This means instead of taking out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
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 Weslaco, the decision will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Weslaco
EcoWatch is different from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Weslaco area so you can find the right window installation company near you.
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 installer included in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their service from a certain company, you won’t see it featured on EcoWatch.
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. Still, we want to ensure we’re highlighting companies that provide 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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Weslaco’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Weslaco window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Weslaco, TX 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 between $200 and $1,200, depending on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and know how to replace a window, it’s possible to install your own windows. However, if you don’t have the time or know-how, we recommend hiring a professional.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
