How Installing Energy-Efficient Windows in Dundalk Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to take the plunge and make the switch:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: Once you install 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 investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Dundalk, that’s about 249 pounds per year on average.

Estimated Cost of Window Replacement in Dundalk

When looking into window installation, each company offers different services and prices. Let’s take a look at some average costs and services.

How Much Do New Windows Cost?

Typically, homeowners in Dundalk can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $285 a year on your energy bills in Dundalk.

Another factor that influences the overall cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

If you’re unsure which type of window installation service you should get, your installer should be able to assist you. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Dundalk

In our search to find the most reliable, eco-friendly window installers in Dundalk, the EcoWatch team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed several window installers in Dundalk and ranked them based on the following methodology:

Service Area

Since this is a guide for Dundalk, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Dundalk.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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

Customer feedback is another very important review factor. If most customers don’t have nice feedback about their service from 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 won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide 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 make sure that investment is protected. Window installation companies with 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 been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Dundalk, MD Window Replacement FAQs

How much should window installation cost?

The average cost of replacing a window ranges between $450 and $650. There are several factors that affect the cost, such as the materials used in designing the windows, local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are and your property’s location.

Which kind of window is the best?

A window’s energy efficiency is influenced by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

Can you install your own windows?

If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or know-how, we recommend getting a professional to do it for you.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on energy costs, replacing all the windows at the same time is the only way to gain that benefit. However, if you have only a few windows that are broken or leaky, you can replace just those.
