How Installing Energy-Efficient Windows in Windsor Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Better temperature control in your home: When you reside in a city like Windsor where the summers can be quite hot, you usually have to depend on your air conditioner to keep your home cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
- 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 value, especially if you have an older home.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.
Estimated Cost of Window Replacement in Windsor
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Generally, Windsor homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. These numbers are based on specific characteristics of your installation, such as size, type, the location of your home, number of windows, material and more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Windsor home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Getting free quotes from several installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Windsor
EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Windsor area so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Windsor's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Windsor window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Windsor, CA Window Replacement FAQs
What is the average cost to install windows?
The average cost of replacing a window can range from $450 to $650. There are several factors that influence how much it costs, such as your property's location, local labor costs, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are and the number of windows.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are awning windows, double-hung and single-hung windows, bay windows, transom windows, picture windows, slider windows and casement windows.
Do you really have to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complicated process that can take a lot of time, so it's best left to the professionals.
How often do you need to replace 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 any damage on them, or they have become difficult to open or close, they may be in need of replacement.
