Calculate how much you can expect to pay for window installation and replacement in San Marcos, TX using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in San Marcos Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to make the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Better temperature control in your home: Residing in a very hot city like San Marcos can often mean depending on your air conditioner to keep your house cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In San Marcos, that's about 507 pounds per year on average.
Estimated Cost of Window Replacement in San Marcos
Windows come in varying shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, San Marcos homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But costs will vary significantly depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a replacement is to think about whether you should get a full-frame or pocket installation.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you choose what's best for your needs. In San Marcos, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in San Marcos
EcoWatch reviews differ from most reviews, as we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in San Marcos and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
San Marcos, TX Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost of replacing a window can range from $450 to $650. There are several factors that affect the cost, including styles and sizes of windows, the number of windows, local labor costs, the materials used in designing the windows, how energy-efficient the windows are and your property's location.
What type of window is the most energy-efficient?
A window's energy efficiency depends on several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installers do?
Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How long does it generally take to install windows?
Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
How often should you replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
