San Bernardino Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in San Bernardino, CA using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

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

Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could help you:

  • Better temperature control in your home: When you reside in a place like San Bernardino where the winters can get chilly, you usually need to rely on your heater to keep your home warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.
  • Decrease your carbon footprint: In San Bernardino, you can lower your indirect greenhouse gas emissions by about 117 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in San Bernardino

When researching window installation, each company offers different services and costs. Let's go over some typical costs and services.

How Much Do New Windows Cost?

Generally, homeowners in San Bernardino can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save San Bernardino homeowners $540+ a year when replacing single-pane windows.

Asking for free quotes from several installers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In San Bernardino, the choice will mostly be based on the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in San Bernardino

EcoWatch reviews differ from other reviews, as we assess these companies through a sustainability lens. We've decided to review the top window installers in San Bernardino primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve San Bernardino so you can find a quality 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 on this list to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to San Bernardino's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of San Bernardino 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 Bernardino, CA Window Replacement FAQs

What is the typical cost to replace windows?

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

What type of window is the best for energy efficiency?

A window's energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I replace my own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or experience, we recommend hiring a professional.

How long does window installation typically take?

Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.

How do you know it's 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 should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
