20 Best Window Companies in San Leandro, CA (2024 Reviews)

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

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:

• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
• Reduce your carbon footprint: In San Leandro, you can cut your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.
• Save money on power bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in San Leandro

When researching window installation, each company offers different services and costs. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will add extra costs to your project.

It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your San Leandro home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide 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 installations, in general there are two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can recommend the best type for your project. In San Leandro, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in San Leandro

In our hunt to find the most reliable, eco-friendly window installers in San Leandro, EcoWatch examined dozens of companies before landing on these. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve San Leandro so you can find the right window installation company near you.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand 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

Customer feedback is another super important review factor. If the majority of customers don’t have nice things to say about their service from 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 try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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