How Installing Energy-Efficient Windows in Tiburon Saves You Money

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

  • Save money on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Reduce your carbon footprint: In Tiburon, you can cut your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Tiburon

When researching window installation, each company offers different services and prices. Let's go over some typical costs and services.

How Much Do New Windows Cost?

The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which carry a higher price tag.

Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

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

What Services do Window Installers Offer?

The first step of a window replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're not sure which type of window installation service you need, your installer can help you out. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Tiburon

In our hunt to make your home improvements easier and more eco-friendly in Tiburon, the EcoWatch Reviews team examined dozens of companies before deciding on these. We've assessed the best window installers in Tiburon mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your power 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 Tiburon, we only included companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Tiburon.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers' prices, 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 well protected. Window installation companies that provide 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 proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Tiburon, CA Window Replacement FAQs

What is the average cost to replace windows in a home?

The typical cost of installing one window ranges between $450 and $650. There are a variety of factors that affect the price, including how energy-efficient the windows are, your property's location, the materials used in designing the windows, the number of windows, styles and sizes of windows and local labor costs.

Which kind of window should I get?

A window's energy efficiency is affected by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your 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 windows?

Windows usually have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
