Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house’s efficiency can also have a considerable impact on home energy conservation. Drafty windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home’s heat or cool air could be lost through your windows.
Installing new, efficient windows on your home can help you save money each month on your power bills — and you can help the environment as well.
Efficient windows are especially important in Seal Beach, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $388 per year.

How Installing Energy-Efficient Windows in Seal Beach Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
- Save on electricity bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Seal Beach
Each window installer offers varying services and has different price points depending on several factors.
How Much Do New Windows Cost?
Generally, homeowners in Seal Beach can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which have a higher price tag.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, but 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?
When it comes to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won’t cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you’re still debating which type of installation to get, you can consult with your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Seal Beach
In our search to make your home improvements easier and more eco-friendly in Seal Beach, the EcoWatch Reviews team assessed dozens of companies before deciding on these. We’ve evaluated the top window installers in Seal Beach mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Seal Beach, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Seal Beach.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, warranty, quality of installation, cost and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Seal Beach, CA Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost of replacing a single window can range between $450 and $650. There are several factors that influence the cost, which include local labor costs, the number of windows, your property’s location, the materials used in designing the windows, how energy-efficient the windows are and styles and sizes of windows.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
How long does it usually take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
