How Installing Energy-Efficient Windows in Napa Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

  • Decrease your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you'll also be cutting your carbon dioxide 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 due to their ability to filter out harmful UV rays.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Napa

Let's take a look at the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, homeowners in Napa can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. This is because of the fact that window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Napa homeowners $655+ a year when replacing single-pane windows.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

When considering window installations, there are generally two kinds that your installer will have: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of deterioration. With this service, your professionals will replace the full window, including the frame, sill and trim. A pocket installation involves replacing a window within the existing frame. This means instead of removing the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which window installation service you need, your installer can assist you. In general, the decision is influenced by 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 Napa

In our hunt to make your home improvements easier and more eco-friendly in Napa, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state 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 Napa so you can find a quality window installation company near you.

Work Quality

We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list 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

We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, cost, warranty, professionalism, quality of installation and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want 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

As discussed, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Napa, CA Window Replacement FAQs

How much should window installation cost?

The average cost of installing a single window can range from $450 to $650. There are many factors that influence the cost, including local labor costs, how energy-efficient the windows are, the materials used in designing the windows, your property's location, styles and sizes of windows and the number of windows.

Which type of window should I get?

A window's energy efficiency is affected by a number of 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 since they are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.

What time of year is the best time to replace my windows?

Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.

How often should you replace your windows?

Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
