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, including:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save $622 a year on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in San Marcos
Let's go over the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. This is due to the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save San Marcos homeowners $622+ a year when replacing single-pane windows.
Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are usually the least expensive 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?
When considering window replacements, there are generally two types that your installer will have: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation 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. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you're still debating which type of installation you need, you can ask your installer and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in San Marcos
In our search to find the most reliable, eco-friendly window installers in San Marcos, the EcoWatch Reviews team evaluated many companies before settling on these. Along with energy efficiency, we evaluated several window installers in San Marcos and assigned rankings based on the following methodology:
Service Area
Since this is a guide for San Marcos, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in San Marcos.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer included on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of parts, cost, quality of installation, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to San Marcos' 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 the climate. If a company has less than 10 years of experience, it loses points in this category.
San Marcos, CA Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a window can range between $450 and $650. There are a variety of factors that influence how much it costs, including styles and sizes of windows, the materials used in designing the windows, your property's location, how energy-efficient the windows are, local labor costs and the number of windows.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
