How Installing Energy-Efficient Windows in Danville Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to think about making the switch:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
Estimated Cost of Window Replacement in Danville
Let's go over the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Typically, homeowners in Danville can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. Costs will vary considerably depending on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
Whether or not you want 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 $657 a year on your energy bills in Danville.
Something else that affects the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. A pocket installation involves replacing a window within the frame that's already there. So, instead of removing the whole unit 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 kind of window installation service you should get, your installer should be able to assist you. Generally, the choice is influenced by 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 Danville
In our search to find the most reliable, eco-friendly window installers in Danville, EcoWatch landed on the above companies as the best window installation companies in the city. We've reviewed the best window installers in Danville mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Danville area so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and variety of services often plays 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that provide a range 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 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.
Danville, CA Window Replacement FAQs
How much does a window install cost?
The national average cost of installing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is typically dependent on the size of the window, the type and material of the window and the location of your property. 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 most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you're handy and have all of the necessary tools 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 one window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
How long does it take to install windows?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
