How Installing Energy-Efficient Windows in Moraga Saves You Money

By upgrading to energy-efficient windows, you can take advantage of several benefits, including:

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
• Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

When considering window installation, each company offers different services and prices. 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 replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.

Whether or not you want energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $579 a year on your energy bills in Moraga.

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

What Services do Window Installers Offer?

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

Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window replacement company should be able to help you decide what’s best for your needs. In Moraga, the decision will mostly depend on how old your home is 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 evaluate your frames and window sills.

How We Choose the Best Window Installers in Moraga

EcoWatch is different from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:

Service Area

Because this is a guide for Moraga, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Moraga.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, professionalism, cost, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Because of Moraga’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Moraga window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
