How Installing Energy-Efficient Windows in Fairfield Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
- Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Fairfield
Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
Generally, homeowners in Fairfield can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at around $600. But costs will vary considerably based on your location, the quality of your products, the number of windows you need and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
It's also worth bearing in mind that energy-efficient windows will typically cost more initially, but Energy Star estimates that upgrading the windows on your Fairfield 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which type of window installation service you should get, your installer can assist you. Typically, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Fairfield
In our search to make your home improvements easier and more eco-friendly in Fairfield, the EcoWatch team landed on the above companies as the best window installation companies in the city. We have reviewed the best window replacement companies in Fairfield mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Fairfield, we only included companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Fairfield.
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 give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of parts, quality of installation, professionalism, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Fairfield's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Fairfield window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Fairfield, CA Window Replacement FAQs
What is the average cost to install windows?
The average cost of replacing a window ranges between $450 and $650. There are many factors that influence how much it costs, such as the number of windows, your property's location, styles and sizes of windows, how energy-efficient the windows are, local labor costs and the materials used in designing the windows.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get 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 have to use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a involved process that can take a lot of time, so it's best handled by the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. 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. What's most important is that the weather should be dry.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
