We've just purchased a 1941 coop apartment in Brooklyn. We had it tested for lead by an EPA accredited inspector with an XRF machine, and the test results were all negative except for the front door and a heating pipe in the bathroom.
I went ahead and arranged for the walls to be replastered (skim coated) and painted, specifically asking the painters not to touch the door or the pipe. Now, however, I'm nervous all of a sudden about how effective the XRF tests really are. I have a 2-year-old and I'm pregnant, and am wondering whether I should get the place tested again post-painting, just to be safe.
thanks for your advice!
