JACK-N-TOOL BOX

They didn't do what they said they would do, which was to mitigate moisture damage to several cottages. They claim to be marine engineers. They have no idea what they are doing, and then fail to supervise their Latino workers. I ultimately found another contractor who cleaned out the mess in the crawlspaces, installed commercial grade sump pumps at the low end of each cottage building, and then put in a mesh to keep their special plastic ground material off direct contact with the ground. All moisture flows to the sump beneath the sump pumps. In the controlled airspace of the crawlspace, these other guys wrapped with plastic material up the exterior walls (but on the inside of course) and seal the perimeters. They sealed all crawlspace vents to keep exterior air (of a higher humidity) from invading the crawlspace area. They installed commercial grade de-humidifiers to reduce the moisture ABOVE the plastic but beneath the floor joists to dry out the crawlspace area--to an average of 35% year around. Large ducts were installed to put de-humidified air into critical areas. Some 4 years after the unprofessional work by Jack N Toolbox the work described immediately above was done for approximately $20,000--and is working! Jack Byer's crews are unsupervised and unprofessional. They have no idea what they're doing, and they cut corners where they don't think the owner will ever venture to see the work.
