This company claims to be able to PIINPOINT a slab leak. That is IMPOSSIBLE! The owner is very nice initially but when you call him with a concern he becomes very rude, mean and nasty. These people are swindlers. Find out the company owners name by going to their website then search his name on the Tarrant County Justice of the Peace Courts website to see how many times he has been sued and how many company names he has operated under. You might also want to do a Google search with the owners name and include sexual assault - you will see what he has been charged with. This is an awful company - do not use them.
