How Installing Energy-Efficient Windows in San Marcos Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
- Protect your valuables from fading: When you switch to energy-efficient windows with 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 power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $491 annually on your energy bills in San Marcos.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in San Marcos
When looking into window installation, each company offers varying services and prices. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. But prices differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door replacements, which will add extra costs to your project.
It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save San Marcos homeowners $491+ a year when replacing single-pane windows.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely 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?
The first step when considering a window replacement is to think about whether you want a full-frame or pocket installation.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re not sure which type of window installation service you should get, your installer should be able to help you out. Generally, the decision 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
The EcoWatch Reviews team is different from most reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
Since this is a guide for San Marcos, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in San Marcos.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, warranty, quality of parts, professionalism, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of San Marcos’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of San Marcos window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
San Marcos, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind 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 most common kinds of replacement windows?
The most common kinds of windows for homes are transom windows, casement windows, picture windows, bay windows, slider windows, awning windows and double-hung and single-hung windows.
What do window installers do?
Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
How long does window installation generally take?
Since a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
