Why you can trust EcoWatch

The EcoWatch Reviews team is all about helping Kensington homeowners find eco-conscious solutions for their homes. If you have outdated, drafty windows, your AC or heating system could be working overtime to heat or cool your home. This means spending more on power bills.

That's also bad news for the environment, as the extra energy used by damaged windows increases your carbon footprint.

Efficient windows are especially important in Kensington, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $657 per year.

How Installing Energy-Efficient Windows in Kensington Saves You Money

When you upgrade to energy-efficient windows, you may see some benefits, including:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
  • Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
  • Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in Kensington

Each window replacement company offers varying services and has varying costs depending on several factors.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.

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

We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. This means instead of taking out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which type of window installation service you need, your installer should be able to help you out. Generally, 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 Kensington

EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. We've reviewed the best window installation companies in Kensington mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Kensington, we gave more points 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 Kensington.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive things to say about their experience with a certain window installation 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 would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that offer 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Kensington, CA Window Replacement FAQs

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

The national average cost to replace a window is around $600 but can range between $200 and $1,200, based on a few different factors. The price is generally 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 initially but can save you hundreds of dollars a year in energy bills.

What kind of window is the best for energy efficiency?

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

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. 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.

Should I replace all my windows at once?

If you're upgrading your windows because of energy-efficiency, replacing all of your windows at once is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
