Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could represent nearly 30% of heating and cooling costs. In Clearlake, where the energy bills are an average of $35 per month, that's almost $$126 per year wasted.

Fortunately, saving you money with upgraded windows also aligns with our goals of reducing energy usage for the environment.

Unlike other sites, EcoWatch ranks window companies on energy efficiency while also considering cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Clearlake Saves You Money

Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:

  • Save money on power bills: Because energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $516 annually on your energy bills in Clearlake.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.

Estimated Cost of Window Replacement in Clearlake

Windows come in various purposes, shapes and styles, so costs and services will differ remarkably depending on your project. Below, we detail the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Generally, Clearlake homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Clearlake home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that influences the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?

There are typically two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Clearlake

EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Clearlake and assigned rankings based on the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Clearlake so you can find the right window installation company near you.

Work Quality

When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain company, it won't be featured on EcoWatch.

Cost

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

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Clearlake, CA Window Replacement FAQs

How much does window installation cost?

The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
