Roof leak and brick veneer

Hello,

My son is in the process of purchasing a row home in Washington, D.C.

Though it was built in 2012, there is a lot of efflorescence on the facade showing a good amount of water coming from weep holes.

He had the home inspected (I could send you a copy of the report if you like) and the inspector found water damage (from incorrectly installed flashing?) at the back of the house, but the front brick veneer has lots of efflorescence with indications of a good amount of water weeping through the weep holes.

I am hoping you can refer a good brick veneer specialist inspector (and someone to find the source of the water) in the Washington, D.C. Area ?

Any advice is appreciated greatly!

Thank you very much for your time and kind consideration,
