How Installing Energy-Efficient Windows in Catonsville Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way.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.
- Save money on energy bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
- 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.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Catonsville, that’s about 249 pounds per year on average.
Estimated Cost of Window Replacement in Catonsville
Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and services that you’ll find from window installers.
How Much Do New Windows Cost?
Generally, homeowners in Catonsville can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. These figures vary based on the specifics of your installation, including number of windows, size, type, material, the location of your home and more.
It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Catonsville homeowners $285+ a year when replacing single-pane windows.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Catonsville
EcoWatch is different from other reviewers since we’re examining these companies through a sustainability lens. We have reviewed the top window installers in Catonsville mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Catonsville so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine 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, professionalism, cost, quality of parts, quality of installation and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Catonsville’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Catonsville window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Catonsville, MD Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
A window’s energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it’s best left to the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
