Our Story

Our woman-owned plumbing company can provide you with professional and certified plumbers at any hour, day or night. Mary Ann Judith founded First Class Plumbing for you! Since 2004, our plumbing company has been providing expert plumbing services to both homeowners and businesses. From fixing leaky faucets to testing your backflow preventer, no job is too small or too big! Mary Ann’s brother, Michael Magnolia, joined the company after working with one of the largest plumbing companies in the area. Mike is a master plumber.

Residential Plumbing

We handle residential plumbing calls of all shapes and sizes. Centrally based out of Annapolis, MD, if you need plumbing repairs because of a leaky faucet, leaky toilet, leaky water heater or frozen pipes, one call does it all. If your furnace breaks or your air conditioning stops working, we can help. We perform drain cleaning, hydro excavation, install sump pumps and more. Our bathroom remodeling services are second to none. Our aim is to be the only residential plumber you ever call.

Commercial Plumbing

Our commercial plumbing repairs, installations and maintenance services have earned us a reputation as commercial plumbers you can trust to get the job done right without breaking the bank. Our business is to keep your business running smoothly. With that in mind, we offer 24/7 plumbing services, so if you need an emergency plumber in Maryland, DC or Northern Virginia, call now. You’ll speak to a plumbing expert who can help you figure out what needs to be done until our commercial plumbers arrive on the scene.
