How Installing Energy-Efficient Windows in San Marino Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, such as:

  • Save money on energy bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $509 annually on your energy bills in San Marino.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in San Marino

Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the typical cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

Keep in mind that energy-efficient windows may have a higher price, 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 you replace double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two types that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the sill, trim and frame. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise the overall cost. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in San Marino

In our hunt to make your home improvements easier and more eco-friendly in San Marino, EcoWatch chose the above companies as the best window installation companies in the city. We’ve evaluated the top window installation companies in San Marino mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for San Marino, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in San Marino.

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 type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback 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 cost, quality of parts, warranty, quality of installation, professionalism and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed previously, windows are a considerable 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

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

San Marino, CA Window Replacement FAQs

What is the typical cost to install windows?

The average cost of replacing a single window ranges from $450 to $650. There are several factors that influence how much it costs, such as local labor costs, the number of windows, how energy-efficient the windows are, styles and sizes of windows, your property’s location and the materials used in designing the windows.

What type of window is the best for energy efficiency?

A window’s energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window replacement companies do?

Window installers visit your property 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.

What time of year is the best time to replace my windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
