How Installing Energy-Efficient Windows in Fair Oaks Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: In Fair Oaks, you can cut your indirect greenhouse gas emissions by about 324 pounds per year when you install energy-efficient windows.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Fair Oaks
Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. Costs will differ significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. Many window companies also offer door installations and other add-ons like baths, coating, shutters and more. These extra services will increase overall project costs.
It’s important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Fair Oaks homeowners $359+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide 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?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this kind 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 cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Fair Oaks
EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Fair Oaks and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Fair Oaks so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, cost, quality of installation, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Fair Oaks’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Fair Oaks window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Fair Oaks, VA Window Replacement FAQs
What is the typical cost to replace windows?
The typical cost to install a single window ranges between $450 and $650. There are many factors that influence how much it costs, such as how energy-efficient the windows are, styles and sizes of windows, your property’s location, local labor costs, the materials used in designing the windows and the number of windows.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t 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 with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend getting a professional to do it for you.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation more difficult.
How long does it typically take to install windows?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
