How Installing Energy-Efficient Windows in San Marcos Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
- Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Decrease your carbon footprint: In San Marcos, you can reduce your indirect greenhouse gas emissions by about 507 pounds per year when you switch to energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in San Marcos
Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. How much it will cost varies based on several factors, like number of windows, type, the location of your home, size, material and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save San Marcos homeowners $380+ per year after replacing single-pane windows.
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 if they are 100% 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?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has noticeable rot or deterioration. Full-frame installations are more involved and will increase the overall cost. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
If you're not sure which type of window installation service you should get, your installer can assist you. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in San Marcos
In our search to make your home improvements easier and more eco-friendly in San Marcos, EcoWatch examined dozens of companies before settling on these. We've reviewed the best window replacement companies in San Marcos primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the San Marcos area so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, cost, professionalism, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. Still, 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
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of San Marcos' climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of San Marcos window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
San Marcos, TX Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to install one window is around $600 but can range between $200 and $1,200, based on several factors. The price is typically 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 a decent amount of money a year in energy bills.
What are the types of windows?
The most common types of windows for homes are awning windows, double-hung and single-hung windows, transom windows, bay windows, picture windows, slider windows and casement windows.
When do I need to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best left to the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
