20 Best Window Companies in Hawthorne, CA (2025 Reviews)

How Installing Energy-Efficient Windows in Hawthorne Saves You Money

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

• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Save money on power bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save around $509 annually on your energy bills in Hawthorne.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: By using less energy once you switch to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Hawthorne

Windows come in varying purposes, styles and shapes, so costs and services will vary considerably based on your project. Below, we detail the average cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

Generally, homeowners in Hawthorne can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. Costs will differ considerably based on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Hawthorne homeowners $509+ each year after replacing single-pane windows.

Something else that affects the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. A pocket installation entails installing a new window within the old frame. This means instead of taking out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to help you choose what’s best for your needs. In Hawthorne, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Hawthorne

In our hunt to make your home improvements easier and more eco-friendly in Hawthorne, the EcoWatch team evaluated dozens of companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Hawthorne and assigned rankings using the following methodology:

Service Area

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

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 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

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of installation, professionalism, quality of parts, cost and more.

Cost

Cheaper windows don’t necessarily 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 awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

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