How Installing Energy-Efficient Windows in Dundalk Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can see 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 Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Dundalk
When looking into window installation, each company provides varying services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. These amounts vary based on the specifics of your installation, including size, number of windows, the location of your home, material, type and more.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full 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. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't carry as large a bill, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're still debating which type of installation to get, you can ask your installer and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Dundalk
In our hunt to make your home improvements easier and more eco-friendly in Dundalk, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Dundalk and ranked them based on the following methodology:
Service Area
Because this is a guide for Dundalk, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Dundalk.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies 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 to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Dundalk, MD Window Replacement FAQs
How much should a window install cost?
The average cost to install one window ranges from $450 to $650. There are many factors that influence the price, such as the materials used in designing the windows, the number of windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs and your property's location.
Which kind of window should I get?
Generally, double-pane windows will be 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 get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers will do the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
