How Installing Energy-Efficient Windows in Concord Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, including:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Save on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Concord
Let’s go over the cost of replacing your windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Though the typical cost of installing a single window is about $600, it can range from $200 to $1,200. But costs will differ significantly depending on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Concord homeowners $579+ a year after replacing single-pane windows.
Costs will also vary based on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are on the simpler end 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 deterioration, you should opt for a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Concord
In our search to find the most reliable, eco-friendly window installers in Concord, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
Because this is a guide for Concord, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Concord.
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 type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Concord’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Concord window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Concord, CA Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost of installing a window ranges from $450 to $650. There are a variety of factors that affect the cost, such as styles and sizes of windows, your property’s location, how energy-efficient the windows are, local labor costs, the number of windows and the materials used in designing the windows.
What are the types of windows?
There are various kinds of windows you can get for your house, including awning windows, picture windows, double-hung and single-hung windows, casement windows, slider windows, bay windows and transom windows.
What do window installation companies do?
Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
