How Installing Energy-Efficient Windows in South Lake Tahoe Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In South Lake Tahoe, that’s about 117 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $503 a year on your bills.

Estimated Cost of Window Replacement in South Lake Tahoe

When researching window installation, each company provides different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ significantly depending on your location, the current condition of your home, the number of windows you need and the quality of your products. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the frame that’s already there. So, instead of tearing out the whole window and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in South Lake Tahoe

In our search to make your home improvements easier and more eco-friendly in South Lake Tahoe, EcoWatch landed on the above companies as the top window installation companies in the city. We’ve decided to assess the top window replacement companies in South Lake Tahoe primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve South Lake Tahoe so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points 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 find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, cost, quality of installation, professionalism, warranty 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 providers’ prices, we awarded higher scores 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 well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of South Lake Tahoe’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of South Lake Tahoe window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
