About Us


Welcome to 301CHIMNEY of Hyattsville, Maryland, a division of American Professional Chimney & Masonry Service. We are proud to have the most respected, reviewed, and experienced staff in the Washington, DC, area. We have won the Angie's List Super Service Award for outstanding customer service in all four categories for which we are eligible for the last five years in a row. Our company is frequently called 301Chimney because of our corresponding phone number which is displayed prominently on our vehicles.


The founder of our company has lived in the Washington, DC, area since 1959 and has been repairing chimneys since 1973. He is this region's most experienced chimney technician and still climbs to the top of the tallest chimneys. He's also a technical resource for 20 field employees while he personally assists homeowners with issues that other companies may not have been able to diagnose or rectify. Some situations require a unique repair approach. Our owner is a perfectionist and expects the same level of commitment from his employees.
