Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's efficiency can also have a big impact on home energy conservation. Drafty windows could lead to spending more on electric bills during the winter or summer months.

That's also bad for the environment because the extra energy required by old windows increases your carbon footprint.

Efficient windows are especially important in Los Alamitos, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $388 each year.

How Installing Energy-Efficient Windows in Los Alamitos Saves You Money

There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

  • Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
  • Better temperature control in your home: Residing in a chilly city like Los Alamitos usually means needing your heater to keep your home cool. Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Los Alamitos

Each window installation company provides various services and has different price points depending on several factors.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, like size, material, number of windows, the location of your home, type and more.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Los Alamitos homeowners $388+ a year after replacing single-pane windows.

Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

Full-frame installations require replacing the entire 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 a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still debating which type of installation you should get, you can talk to your installer and get their advice. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Los Alamitos

In our search to find the most reliable, eco-friendly window installers in Los Alamitos, EcoWatch assessed many companies before settling on these. Along with energy efficiency, we analyzed several window installers in Los Alamitos and assigned rankings using the following methodology:

Service Area

Since this is a guide for Los Alamitos, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Los Alamitos.

Work Quality

We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has received lots 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 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 most other categories, including warranty, quality of parts, quality of installation, cost, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Los Alamitos, CA Window Replacement FAQs

How much should window installation cost?

The average cost of replacing a window ranges between $450 and $650. There are several factors that influence how much it costs, including local labor costs, the materials used in designing the windows, the number of windows, your property's location, styles and sizes of windows and how energy-efficient the windows are.

Which kind of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that 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 needed to replace your own windows, we recommend hiring a professional. The window installation process 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 professional is a faster, more efficient and much safer option.

Should I replace my windows all at the same time?

If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
