How Installing Energy-Efficient Windows in Walnut Creek Saves You Money
By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Save on power bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- 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.
- Reduce your carbon footprint: In Walnut Creek, you can lower your indirect greenhouse gas emissions by about 117 pounds per year once you upgrade to energy-efficient windows.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Walnut Creek
When researching window installation, each company provides different services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. This is because of the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you choose energy-efficient windows is another factor that will affect 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 Walnut Creek.
We recommend requesting free quotes from several window companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Walnut Creek
EcoWatch reviews are different from other reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Walnut Creek and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Walnut Creek so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of parts, professionalism, warranty, quality of installation and more.
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 previously, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Walnut Creek’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Walnut Creek window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Walnut Creek, CA Window Replacement FAQs
How much should window installation cost?
The average cost to replace a window ranges between $450 and $650. There are a variety of factors that affect the price, which include styles and sizes of windows, your property’s location, the number of windows, local labor costs, how energy-efficient the windows are and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your house, including picture windows, slider windows, double-hung and single-hung windows, transom windows, casement windows, bay windows and awning windows.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed 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 one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
When is the best time of year to replace 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. Most importantly, the weather should be dry.
How long does it typically take to install windows?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
