El Segundo Window Cost Calculator

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

There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • Reduce your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save on power bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save around $509 annually on your energy bills in El Segundo.

Estimated Cost of Window Replacement in El Segundo

Let’s go over the cost of window installation and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your El Segundo home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

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

A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window replacement company should be able to help you understand what’s best for your needs. In El Segundo, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in El Segundo

In our search to find the most reliable, eco-friendly window installers in El Segundo, the EcoWatch team assessed dozens of companies before settling on these. We have decided to evaluate the top window replacement companies in El Segundo mostly 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 power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for El Segundo, we only included companies that serve 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 El Segundo.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, warranty, quality of parts, cost and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when 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 to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

El Segundo, CA Window Replacement FAQs

How much should a window install cost?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the type and material of the window, the location of your property 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 different types of windows?

The most common kinds of windows for homes include: bay windows, transom windows, double-hung and single-hung windows, slider windows, awning windows, picture windows and casement windows.

Can I install my own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or experience, we recommend getting a professional to do it for you.

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 probably need to 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.
