Estimated Cost of Window Replacement in Fountain Valley

Each window installer provides various services and has varying costs based on several factors.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. Costs will vary considerably based on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.

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

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies 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 a new style for your windows or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails replacing a window within the existing frame. So, instead of tearing out the whole unit and rebuilding it, the window installer 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 should get, your installer can advise you. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fountain Valley

In our search to find the most reliable, eco-friendly window installers in Fountain Valley, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

Service Area

Because this is a guide for Fountain Valley, we only included 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 Fountain Valley.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent 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 nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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 significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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