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

When you upgrade to energy-efficient windows, you may see a few perks, including:

• Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
• Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
• Protect your investment: If you have an older 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 property if you decide to sell.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Los Alamitos, that’s about 117 pounds per year on average.

Estimated Cost of Window Replacement in Los Alamitos

When looking into window installation, each company provides varying services and prices. Let’s look at some average costs and services.

How Much Do New Windows Cost?

Typically, Los Alamitos homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will make your project cost more.

Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

There are typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, 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 consult with your provider and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Los Alamitos

The EcoWatch Reviews team differs from most reviewers, as we examine these companies through a sustainability lens. We have decided to evaluate the top window installers in Los Alamitos primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Los Alamitos, we only included companies that provide services to the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Los Alamitos.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points 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 with 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 proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
