The federal lead rule is decided by the year the house was built, not by the county — but the housing stock of a county tells you how often it comes up. Any home from before 1978 needs a Lead-Safe certified firm for paid work.
Describing the job costs nothing
Nothing is measured or ordered until you say so. Useful on a first call: how many windows, what type they are, and what is wrong with them.
- License
- Held by the contractor and issued in Maryland. Ask which name it is held under — a trading name and the licensed entity are often not the same.
- Lead certification
- Required by federal rule for paid work on any home built before 1978. It has a number, and the firm should give it without hesitating.
- The call
- Describing the job commits you to nothing. Nothing is measured or ordered until you say so.
- Coverage
- By town, not by region. St. Mary's County and the towns around it.
