How Installing Energy-Efficient Windows in Chillum Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, such as:
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way.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 raise the value of your home if you decide to sell.
- Save money on energy bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll use less energy to heat or cool your home.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Chillum
When considering window installation, each company offers different services and prices. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Chillum can anticipate that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
When it comes to window replacements, there are typically two types that your provider will have: 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 a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Chillum, the decision will mostly depend on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Chillum
EcoWatch differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
Because this is a guide for Chillum, we paid more attention to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Chillum.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in 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, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, professionalism, quality of installation, quality of parts, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Chillum, MD Window Replacement FAQs
What is the typical cost to install windows in a home?
The average cost of installing a window can range from $450 to $650. There are many factors that affect the cost, such as styles and sizes of windows, local labor costs, the number of windows, how energy-efficient the windows are, the materials used in designing the windows and your property’s location.
What type of window is the best for energy efficiency?
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 get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installation companies will do the entire process — from replacing your old windows with new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.
How long does it usually take to install windows?
Because the average installation time of a window is 30 minutes, around 16 windows can be installed during an 8-hour work day.
