How Installing Energy-Efficient Windows in Ellicott City Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, including:
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Ellicott City
Each window installation company provides various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
According to our market research, the typical cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will make your project cost more.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $289 a year on your energy bills in Ellicott City.
Getting free quotes from several companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step when considering a replacement is to decide whether you should get a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of damage. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window without taking out the entire frame, which is usually less expensive than a full-frame installation.
If you're still debating which kind of installation you need, you can ask your installer and get their advice. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Ellicott City
In our hunt to make your home improvements easier and more eco-friendly in Ellicott City, the EcoWatch team assessed dozens of companies before deciding on these. We have evaluated the top window replacement companies in Ellicott City mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Ellicott City, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Ellicott City.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, warranty, cost, quality of parts, professionalism and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Ellicott City, MD Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost to install one window ranges between $450 and $650. There are many factors that affect how much it costs, including local labor costs, your property's location, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and styles and sizes of windows.
What are the different types of windows?
There are several different kinds of windows you can get for your home, such as transom windows, casement windows, bay windows, picture windows, double-hung and single-hung windows, slider windows and awning windows.
What do window installation companies do?
Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
When is it time to replace your windows?
Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
Should I replace all my windows at the same time?
If you're upgrading your windows to save on your energy bills, replacing all of your windows together is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
