How Installing Energy-Efficient Windows in Cotati Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, including:

  • More efficient energy usage in your home: In Cotati where the winters can get very cold, energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your house warm.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save $418 a year on your bills.
  • Protect your valuables: Many Energy Star certified 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 it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way.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 Cotati

When researching window installation, each company offers varying services and costs. Let's take a look at some typical costs and services.

How Much Do New Windows Cost?

Although the typical of installing one window is around $600, it can range from $200 to $1,200. How much it will cost you varies based on several factors, including material, number of windows, the location of your home, size, type and more.

With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Cotati homeowners $418+ a year after replacing single-pane windows.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first step when considering a window installation is to decide whether you should get a full-frame or pocket installation.

A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.

Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Cotati

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and range of services often plays 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 consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain installer, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety 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 give you 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 good track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Cotati, CA Window Replacement FAQs

How much should window installation cost?

The national average cost to install one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

The most common kinds of windows for homes are double-hung and single-hung windows, transom windows, awning windows, picture windows, slider windows, casement windows and bay windows.

Can you replace your own windows?

Even though you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

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

Replacement windows can be installed at any time, 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 home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
