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

By switching to energy-efficient windows, you can take advantage of several benefits, such as:

  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in San Ramon

Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the average costs and the primary services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save San Ramon homeowners $579+ a year after replacing single-pane windows.

We advise getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you need, you can ask your installer and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in San Ramon

The EcoWatch Reviews team differs from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in San Ramon and ranked them based on the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.

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 make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

San Ramon, CA Window Replacement FAQs

How much does a window install cost?

The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. 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 most common types of replacement windows?

There are several different types of windows you can get for your house, including bay windows, awning windows, slider windows, casement windows, transom windows, picture windows and double-hung and single-hung windows.

What do window installation companies do?

Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, 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 your home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.

How often do you need to replace windows?

Windows typically last about 20 to 30 years, but anytime you see 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.
