Estimated Cost of Window Replacement in San Jose

Let’s take a look at the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in San Jose can expect that most window installations will cost between $250 and $1,200, with the average cost at around $600. How much it will cost is based on several factors, like number of windows, the location of your home, material, size, type and more.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $562 a year on your energy bills in San Jose.

Another factor that influences the total cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a replacement is to figure out whether you should get a full-frame or pocket installation.

Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. Because these installations are more involved, they will raise overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

If you’re still trying to decide which type of installation you need, you can ask your installer and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in San Jose

EcoWatch reviews are different from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have positive feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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