How Installing Energy-Efficient Windows in Kentfield Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Kentfield, that's about 117 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Kentfield

Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you'll find from window installers.

How Much Do New Windows Cost?

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

It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Kentfield home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

Full-frame installations involve replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has considerable damage or rot. Full-frame installations are more involved and will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the 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.

Your window replacement company should be able to help you decide what's best for your needs. In Kentfield, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Kentfield

EcoWatch differs from other reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Kentfield and ranked them using the following methodology:

Service Area

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

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 a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, professionalism, quality of parts and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Kentfield, CA Window Replacement FAQs

How much should window installation cost?

The average cost to replace one window ranges between $450 and $650. There are many factors that affect how much it costs, such as styles and sizes of windows, the number of windows, how energy-efficient the windows are, local labor costs, your property's location and the materials used in designing the windows.

What kind of window is the best for energy efficiency?

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 typically the most energy-efficient since they are certified by the U.S. Department of Energy.

When should I use a window installation company?

Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer option.

How long does window installation typically take?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.

When is the best time of year to replace windows?

Although you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation harder.
