California Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in California, MD 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 California Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

  • Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: When you switch 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.
  • Better temperature control in your home: Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.

Estimated Cost of Window Replacement in California

Each window replacement company provides various services and has different costs depending on several factors.

How Much Do New Windows Cost?

Generally, California homeowners can anticipate their window installations to range from $250 to $1,200. The average cost sits at around $600. Costs will differ significantly based 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 door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your California home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several installers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) entail replacing a window within its 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 choose which type of installation you should get.

How We Choose the Best Window Installers in California

EcoWatch differs from other reviewers because we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve California so you can find the right window installation company near you.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

Because of California's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of California window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

California, MD Window Replacement FAQs

What is the average cost to install windows in a home?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

There are several different kinds of windows you can get for your home, such as double-hung and single-hung windows, awning windows, casement windows, bay windows, transom windows, slider windows and picture windows.

Can I install my own windows?

Although you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

Should I replace my windows all at once?

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