How Installing Energy-Efficient Windows in St. Helena Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

• Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save some money on your bills.
• Better temperature control in your home: When you live in a place like St. Helena where the winters can be chilly, you usually need to depend on your heater to keep your home warm. Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in St. Helena

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the typical costs and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, homeowners in St. Helena can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. How much it will cost you varies depending on several factors, like number of windows, the location of your home, material, size, type and more.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save St. Helena homeowners $518+ a year when replacing single-pane windows.

Something else that influences the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and light, 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 thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you're still debating which kind of installation to get, you can consult with your provider and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in St. Helena

In our search to find the most reliable, eco-friendly window installers in St. Helena, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

Since this is a guide for St. Helena, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in St. Helena.

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you opt for. 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, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, warranty, cost, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven 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.
