How Installing Energy-Efficient Windows in Del Rio Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could help you:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
- Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on electricity bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $396 annually on your energy bills in Del Rio.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in Del Rio
Each window installation company offers varying services and has different price points depending on a few factors.
How Much Do New Windows Cost?
Typically, homeowners in Del Rio can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. These amounts are based on the specifics of your installation, including type, number of windows, size, material, the location of your home and more.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $396 a year on your energy bills in Del Rio.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window within the old frame. So, instead of taking out the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re still trying to decide which type of installation to get, you can consult with your provider and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Del Rio
EcoWatch reviews differ from most reviews because we assess these companies through a sustainability lens. We’ve decided to evaluate the best window replacement companies in Del Rio mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Del Rio, we only included companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Del Rio.
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 in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of installation, quality of parts 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Del Rio’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Del Rio window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
