How Installing Energy-Efficient Windows in Alum Rock Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to make the switch:

• 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.
• Protect your investment: If you have a relatively old home, your windows are most likely outdated.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.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Alum Rock

When looking into window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. But costs will differ significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Alum Rock homeowners $562+ a year when replacing single-pane windows.

Requesting free quotes from several installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

There are typically two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of removing the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Alum Rock

EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. We’ve decided to assess the top window installation companies in Alum Rock primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Alum Rock area 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 of window you choose. We do rate window installers higher 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 highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including warranty, professionalism, cost, quality of installation, quality of parts and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, 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 to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
