Had a structural engineer out this last week to check our foundation. He said structurally we look fine but we have crappy drainage around the house and need to have a hydrostatic line test for any slab leaks. Anyone have someone you recommend for doing this? We are in north Dallas. Also sounds like we need to have our yard worked on pretty significantly, which we already knew. Previous owners had quite a few drains put in the yard but it all puddles in different places. Any suggestions would be welcome
