How Installing Energy-Efficient Windows in San Jose Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
• Save money on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $562 annually on your energy bills in San Jose.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in San Jose

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 typical cost to replace a single window is about $600 but can range 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 installers also offer door replacements, which will add extra costs to your project.

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

Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're unsure which window installation service you need, your installer can help you out. In general, the decision is influenced by 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 San Jose

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

Service Area

Because this is a guide for San Jose, we only included companies that cover the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in San Jose.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain installer, 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 providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
