Rancho Palos Verdes Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Rancho Palos Verdes, 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 Rancho Palos Verdes Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Better temperature control in your home: Residing in a chilly place like Rancho Palos Verdes usually means needing your heater to keep your house cool. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky.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 Rancho Palos Verdes

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

How Much Do New Windows Cost?

Generally, Rancho Palos Verdes homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost is based on several factors, like material, type, number of windows, the location of your home, size and more.

It's also worth noting that energy-efficient windows will cost more initially, but Energy Star predicts that switching out the windows on your Rancho Palos Verdes home can mean 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. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installation company will be able to help you understand what's best for your needs. In Rancho Palos Verdes, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Rancho Palos Verdes

In our hunt to make your home improvements easier and more eco-friendly in Rancho Palos Verdes, EcoWatch assessed many companies before settling on these. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:

Service Area

Since this is a guide for Rancho Palos Verdes, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Rancho Palos Verdes.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. 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, cost, quality of parts, warranty, professionalism and more.

Cost

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

Warranty

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

Years of Experience

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

Rancho Palos Verdes, CA Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is often influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

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

What time of year should I replace my windows?

Even though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have only one or two windows that are damaged or leaky, you can replace just those.
