How Installing Energy-Efficient Windows in University Of California Davis Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to think about making the switch:

  • Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save $650 a year on your bills.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in University Of California Davis

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

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost you is based on several factors, including the location of your home, type, material, number of windows, size and more.

It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your University Of California Davis home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

We recommend requesting free quotes from several window installation companies to find the one that works best for you.

What Services do Window Installers Offer?

The first step when considering a replacement is to figure out whether you want a full-frame or pocket installation.

A full-frame installation replaces the full window, including the windowsill, 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 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.

If you're unsure which type of window installation service you should get, your installer should be able to assist you. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in University Of California Davis

EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the University Of California Davis area so you can find a quality window installation company near you.

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 in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, we gave higher scores 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 be certain that investment is well protected. Window installation companies that provide 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 been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

University Of California Davis, CA Window Replacement FAQs

How much should window installation cost?

The typical cost to install a single window ranges between $450 and $650. There are many factors that influence how much it costs, including how energy-efficient the windows are, the materials used in designing the windows, the number of windows, styles and sizes of windows, local labor costs and your property's location.

What type of window is the most energy-efficient?

A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

You should hire a window installation company whenever you need new windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.

Should I replace all my windows at the same time?

If you're upgrading your windows to get more efficient windows, replacing all of the windows at the same time is the only way to gain that benefit. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
