How Installing Energy-Efficient Windows in Boonsboro Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, including:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Better temperature control in your home: Residing in a very cold city like Boonsboro can often mean depending on your heater to keep your house cool. Energy-efficient windows can lower how much heat is lost through your windows when heating your home.
Estimated Cost of Window Replacement in Boonsboro
Windows come in various purposes, shapes and styles, so costs and services will differ considerably depending on your project. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
On average, homeowners in Boonsboro can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. These numbers vary based on the specifics of your installation, such as material, the location of your home, size, number of windows, type and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Boonsboro homeowners $298+ a year after replacing single-pane windows.
We recommend getting free quotes from several window installation companies to find the one that works best for you.
What Services do Window Installers Offer?
When it comes to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window replacement company will be able to help you choose what's best for your needs. In Boonsboro, the decision will mostly depend on how old your home is and if there's any damage. Wood can decay if it's not maintained properly 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 Boonsboro
The EcoWatch Reviews team is different from most reviewers, as we look at these companies through a sustainability lens. We've decided to assess the best window replacement companies in Boonsboro mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Boonsboro, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Boonsboro.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, warranty, quality of installation, cost, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Boonsboro, MD Window Replacement FAQs
What is the average cost to replace windows?
The average cost to replace a window ranges from $450 to $650. There are several factors that affect the price, such as your property's location, the materials used in designing the windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the number of windows.
What kind of window is the best for energy efficiency?
A window's energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
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 the windows together is the only way to gain that benefit. However, if you have only one or two windows that are broken or drafty, you can replace just those.
