I just bought a rowhouse in Petworth that’s in need of some foundation work. Prior to purchase my inspector let me know that the right corner in the basement had some water damage, but nothing that could not be fixed. Over the last couple of weeks, I have received solutions/estimates from two different companies (looking to get two more). Both companies provided very different solutions and thus estimates. Below is a quick summary the problem and the two proposed solutions. Would love to get some thoughts from the PoP community and any recommendations from folks.
Problem: Right side of house settling more than left. Water intrusion in right side corner of basement. Mold in right corner. Cracks in bricks on the right side. Right side pier on porch sinking.
JES: To level house, put in 6 push piers. rebuild right porch pier. To stop water, install french drain inside and outside of the of house. Install sump pump. Remediate mold. Cost: $22,000
AquaGuard: Dig and underpin house to stop from settling further. House cannot be leveled without damaging neighbors houses(I have a middle row house). Would not recommend piers for old rowhouses (mine built in 1924) underpin and rebuild right porch pier. To stop water, install french drain inside and outside of the of house. Install sump pump. Remediate mold. Cost: $14,000″
