How Installing Energy-Efficient Windows in Dundalk Saves You Money
Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Reduce your carbon footprint: In Dundalk, you can lower your indirect greenhouse gas emissions by about 249 pounds per year after you install energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Dundalk
Windows come in various purposes, shapes and styles, so costs and services will vary remarkably depending on your project. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. These figures vary depending on the specifics of your installation, including type, material, number of windows, the location of your home, size and more.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Dundalk homeowners $284+ a year after replacing single-pane windows.
We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the total window, including the sill, frame and trim. 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 kind of installment if you have any pre-existing rot or water damage.
Your window replacement company should be able to help you decide what's best for your needs. In Dundalk, the decision will mostly depend on the age of your home and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Dundalk
EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. We've evaluated the top window installers in Dundalk mostly 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 lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Dundalk, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Dundalk.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. 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 online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, 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. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Dundalk's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Dundalk window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Dundalk, MD Window Replacement FAQs
How much does a window install cost?
The average cost to replace a window ranges between $450 and $650. There are many factors that influence how much it costs, which include the number of windows, your property's location, the materials used in designing the windows, local labor costs, styles and sizes of windows and how energy-efficient the windows are.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How long does it generally take to install windows?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
