How Installing Energy-Efficient Windows in Cotati Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Cotati, that's about 117 pounds per year on average.
  • Save on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.

Estimated Cost of Window Replacement in Cotati

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

How Much Do New Windows Cost?

On average, Cotati homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These figures are based on specific characteristics of your installation, including material, the location of your home, type, number of windows, size and more.

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

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In regard to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the overall 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 entails installing a new window within the frame that's already there. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which kind of installation to get, you can talk to your provider and get their recommendation. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Cotati

The EcoWatch Reviews team differs from most reviewers because we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:

Service Area

Since this is a guide for Cotati, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Cotati.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, quality of installation, warranty, cost and more.

Cost

This one is a give-and-take: as with other services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Cotati, CA Window Replacement FAQs

How much does a window install cost?

The typical cost of installing a window can range from $450 to $650. There are a variety of factors that influence how much it costs, such as the number of windows, how energy-efficient the windows are, the materials used in designing the windows, local labor costs, styles and sizes of windows and your property's location.

What are the different kinds of windows?

There are various kinds of windows you can get for your house, including double-hung and single-hung windows, slider windows, picture windows, awning windows, transom windows, bay windows and casement windows.

What do window installers do?

Window installers go to your property to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.

When is it time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
