How Installing Energy-Efficient Windows in Berkeley Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Berkeley, that’s about 206 pounds per year on average.
Estimated Cost of Window Replacement in Berkeley
Windows come in various purposes, styles and shapes, so costs and services will vary greatly depending on your project. Below, we detail the average cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These amounts are based on specific characteristics of your installation, like size, type, material, number of windows, the location of your home and more.
It’s also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Berkeley home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Berkeley, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

We’ve assessed the best window installation companies in Berkeley mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Berkeley area so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, quality of parts, professionalism, quality of installation, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, 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. For that reason, window installation companies that offer 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 been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Berkeley, NJ Window Replacement FAQs
What is the average cost to install new windows?
The national average cost of replacing a window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
A window’s energy efficiency is influenced 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 often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.
Should I replace my windows all at once?
If your windows are greater than 20 years old, it’s probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
