Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s efficiency can also have a large impact on home energy conservation. Drafty or leaky windows can make your AC or heater work extra hard in the summer or winter.
That’s also bad news for the environment because the extra energy required by outdated windows increases your carbon footprint.
We’ve compiled a guide on the top installation companies to help you in your research, so you can not only benefit from brand-new windows, but also save money on your electric bills.

How Installing Energy-Efficient Windows in Laguna Hills Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: Installing energy-efficient windows lowers 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- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Laguna Hills
Windows come in different purposes, styles and shapes, so costs and services will differ considerably based on your project. Below, we go over the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $388 a year on your energy bills in Laguna Hills.
Requesting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
When considering window installations, there are typically two types that your installer will have: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you’re still debating which type of installation you should get, you can talk to your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Laguna Hills
In our hunt to find the most reliable, eco-friendly window installers in Laguna Hills, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for Laguna Hills, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Laguna Hills.
Work Quality
When installing new windows, the quality and range of services often plays 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 consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most 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 warranty, quality of parts, quality of installation, professionalism, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Laguna Hills’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Laguna Hills window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Laguna Hills, CA Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
A window’s energy efficiency depends on a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Do you really have to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.
Should I replace all my windows at once?
If your windows are more than 20 years old, it’s probably time 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 once will involve less paperwork and less stress.
