Lake Los Angeles Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Lake Los Angeles, 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 Lake Los Angeles Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, including:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Reduce your carbon footprint: In Lake Los Angeles, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Lake Los Angeles

Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Typically, Lake Los Angeles homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers vary depending on the specifics of your installation, including number of windows, material, the location of your home, type, size and more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Lake Los Angeles homeowners $509+ a year after replacing single-pane windows.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether 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?

The first step of an installation is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the frame that’s already there. This means instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can advise you on the best type for your project. In Lake Los Angeles, the decision will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Lake Los Angeles

EcoWatch differs from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Lake Los Angeles, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Lake Los Angeles.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer 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

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, cost, professionalism, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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

Lake Los Angeles, CA Window Replacement FAQs

How much does a window install cost?

The average cost to install a window can range from $450 to $650. There are many factors that affect the cost, such as your property’s location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows and local labor costs.

What kind of window is the best for energy efficiency?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be 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 attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

What time of year is a good time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
