Kensington Window Cost Calculator

How Installing Energy-Efficient Windows in Kensington Saves You Money

By upgrading to energy-efficient windows, you can enjoy several benefits, such as:

  • Decrease your carbon footprint: In Kensington, you can cut your indirect greenhouse gas emissions by about 117 pounds per year after you install energy-efficient windows.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Better temperature control in your home: Living in a chilly city like Kensington often means depending on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Kensington

Windows come in various purposes, styles and shapes, so costs and services will vary greatly based on your project. Below, we detail the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

Generally, Kensington homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. Costs will differ considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $579 a year on your energy bills in Kensington.

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

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other 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 surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Kensington, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Kensington

In our hunt to make your home improvements easier and more eco-friendly in Kensington, EcoWatch chose the above companies as the best window installation companies in the city. We have evaluated the best window installers in Kensington mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

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

Work Quality

We're willing to bet that you're looking for professionals who 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

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

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and labor 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 installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Kensington, CA Window Replacement FAQs

How much does a window install cost?

The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the size of the window, the location of your property 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.

Which type of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved 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 professional is a faster, more efficient and much safer alternative.

How long does it generally take to install windows?

Because a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.

What time of year is the best time to replace my windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. 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 doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
