Estimated Cost of Window Replacement in Bellflower

Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you’ll find from window installation companies.

How Much Do New Windows Cost?

On average, Bellflower homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

It’s also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Bellflower home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are 100% 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?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the entire window, including the trim, sill and frame. A pocket installation involves replacing a window within the old frame. This means instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which type of window installation service you need, your installer can advise you. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Bellflower

EcoWatch reviews differ from other reviews because we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

Because this is a guide for Bellflower, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Bellflower.

Work Quality

We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, quality of installation, warranty, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

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

Due to Bellflower’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Bellflower window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
