How Installing Energy-Efficient Windows in Windsor Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- 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.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Windsor, that's about 117 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Windsor
Each window installer provides various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
Typically, Windsor homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because of the fact that window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $418 a year on your energy bills in Windsor.
Requesting free quotes from several companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. Because full-frame installations are more involved, they will increase overall costs. A pocket installation entails replacing a window without taking out the whole frame, which is usually cheaper than a full-frame installation.
Your window installation company will be able to help you choose what's best for your needs. In Windsor, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Windsor
In our hunt to make your home improvements easier and more eco-friendly in Windsor, EcoWatch evaluated dozens of companies before deciding on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Windsor, we gave more points to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Windsor.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher 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 most customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when 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 be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Windsor, CA Window Replacement FAQs
What is the average cost to install windows?
The average cost of installing a window can range from $450 to $650. There are many factors that influence the cost, such as the materials used in designing the windows, styles and sizes of windows, local labor costs, how energy-efficient the windows are, your property's location and the number of windows.
What are the most common types of replacement windows?
The most common types of windows for homes are transom windows, double-hung and single-hung windows, picture windows, bay windows, slider windows, awning windows and casement windows.
When should I 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 option.
How long does window installation take?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
