J.A. Smith & Co. was established in 1985 by J. Allen Smith Jr. and Gregory J. Smith. But our roots go deeper — the patriarch, James A. Smith Sr., started his career in 1951 with the W.L. Hastings Company in Elkridge.

I simply do not have enough good things to say about this company! We are new homeowners with a lot of things we don't understand. JA Smith has been INCREDIBLE — taking the time to explain things. Sharon is lovely and always helpful. Greg spent 20 minutes on the phone explaining how a boiler worked! Rich has saved us twice in 3 weeks.

Mack just serviced the plumbing in my kitchen. I was bracing myself for a large fix and bill but he tried little steps to remedy the problem — and they worked. He took the time to educate me on how to prevent the issue. It's really hard to find honest service, and I am so happy to have found this company.

I never leave Google reviews but for this amazing company I had to. We had what we thought to be an emergency with our main water line. Nobody could help or said it was 'too big.' I called J.A. Smith and they were AMAZING — hands down one of the best companies I have ever experienced.
