How Installing Energy-Efficient Windows in Napa Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save some money on your bills.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Decrease your carbon footprint: In Napa, you can lower your indirect greenhouse gas emissions by about 117 pounds per year after you upgrade to energy-efficient windows.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Napa

Windows come in varying styles, shapes and purposes, so costs and services will differ greatly depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

It’s important to note 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 $518+ a year when replacing single-pane windows.

Something else that affects the total cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation involves replacing a window within the old frame. So, instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you decide what’s best for your needs. In Napa, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Napa

EcoWatch differs from other reviewers because we’re examining these companies through a sustainability lens. We’ve reviewed the top window installation companies in Napa mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Napa, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Napa.

Work Quality

When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when 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 significant investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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 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.
