That's bad news for your wallet and the environment, but one of the top window installation companies can help with that.

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

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:

  • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables from fading: When you upgrade 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.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in San Ramon

Windows come in different shapes, styles and purposes, so costs and services will differ considerably depending on your project. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

According to our market research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because window installations are based 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.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save San Ramon homeowners $657+ per year after replacing single-pane windows.

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, though 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?

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

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the entire window, including the frame, trim and sill. Pocket installations are on the simpler end and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you're not sure which kind of window installation service you should get, your installer can assist you. In general, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve San Ramon so you can find the best 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 installer featured in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most 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 most other categories, including quality of installation, quality of parts, warranty, professionalism, cost and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of San Ramon's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of San Ramon 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 Ramon, CA Window Replacement FAQs

How much does a window install cost?

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

Which type of window should I get?

A window's energy efficiency depends on a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
