How Installing Energy-Efficient Windows in El Monte Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Upgrading to energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: In El Monte, you can cut your indirect greenhouse gas emissions by about 117 pounds per year when you switch to energy-efficient windows.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in El Monte

Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. 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 companies also offer door replacements, which carry a higher price tag.

Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $509 a year on your energy bills in El Monte.

The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the complete window, including the frame, trim and sill. A pocket installation involves installing a new window without replacing the frame. This means instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you decide which type of installation you should get.

How We Choose the Best Window Installers in El Monte

EcoWatch reviews differ from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:

Service Area

Since this is a guide for El Monte, we gave more points to companies that serve the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in El Monte.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide 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

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