How Installing Energy-Efficient Windows in Bel Air South Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you'll also be decreasing 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 value, especially if your home is on the older side.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Bel Air South
When researching window installation, each company offers different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
Even though the typical to replace a single window is around $600, it can range from $200 to $1,200. These numbers vary based on specific characteristics of your installation, including number of windows, material, type, the location of your home, size and more.
It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Bel Air South homeowners $285+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window companies to find the one that works best for you.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the frame that's already there. This means instead of tearing out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you choose what's best for your needs. In Bel Air South, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Bel Air South
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Bel Air South so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of parts, cost, quality of installation, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Bel Air South's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Bel Air South window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.
How do you know it's time to replace your windows?
