How Installing Energy-Efficient Windows in Baltimore Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
Estimated Cost of Window Replacement in Baltimore
Windows come in varying styles, purposes and shapes, so costs and services will vary greatly depending on your project. Below, we go over the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.
It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your Baltimore home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
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 involved and will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you choose what’s best for your needs. In Baltimore, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Baltimore
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has received a lot 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 positive feedback about their service from a certain company, it won’t be featured on EcoWatch.
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 ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Baltimore’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Baltimore window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
