How Installing Energy-Efficient Windows in Santa Monica Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change are the following:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Santa Monica, that's about 117 pounds per year on average.
  • Save money on electricity bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.

Estimated Cost of Window Replacement in Santa Monica

Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Typically, Santa Monica homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost you is based on several factors, like material, type, number of windows, size, the location of your home and more.

Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the total window, including the frame, trim and sill. Pocket installations are on the simpler end and won't cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

If you're unsure which window installation service you need, your installer can assist you. Typically, the choice is influenced by 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 Santa Monica

In our search to find the most reliable, eco-friendly window installers in Santa Monica, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Santa Monica area so you can find the best window installation company near you.

Work Quality

When it comes to 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

We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, cost, quality of installation, warranty and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Santa Monica, CA Window Replacement FAQs

What is the typical cost to replace windows?

The average cost to install a window ranges between $450 and $650. There are several factors that influence the price, including how energy-efficient the windows are, styles and sizes of windows, your property's location, the number of windows, the materials used in designing the windows and local labor costs.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies offer?

Window installers will do the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is it time to replace your windows?

Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to determine if they need any repairs or replacements.
