How Installing Energy-Efficient Windows in Bel Air South Saves You Money
There are several benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Bel Air South
When researching window installation, each company provides varying services and costs. Let’s go over some average costs and services.
How Much Do New Windows Cost?
On average, Bel Air South homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. How much it will cost varies based on several factors, such as the location of your home, material, type, size, number of windows and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from 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 provide decent insulation for your home.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you’re unsure which window installation service you need, 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 Bel Air South
EcoWatch reviews differ from most reviews since we assess these companies through a sustainability lens. We’ve reviewed the best window installation companies in Bel Air South mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Bel Air South so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Bel Air South, MD Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don’t have the time or experience, we recommend hiring a professional.
How do you know it’s time to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
How long does window installation take?
Since a window takes about 30 minutes to install, about 16 windows can be installed during a typical 8-hour work day.
