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

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:

  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In San Leandro, that's about 117 pounds per year on average.
  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in San Leandro

Each window installer provides various services and has different prices depending on several factors.

How Much Do New Windows Cost?

Generally, homeowners in San Leandro can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. This is due to the fact that window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

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

We advise getting free quotes from multiple window installers to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has significant deterioration. Because full-frame 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 involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

Your window replacement company will be able to help you figure out what's best for your needs. In San Leandro, the decision will mostly depend on the age of your windows and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in San Leandro

EcoWatch differs from other reviewers because 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 the best window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to San Leandro's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of San Leandro window companies to prepare homes for the climate.
