What Detroit homeowners
actually say.
“They told me I didn't need a full system — just two crack injections. Saved me about $14,000. Three years later, still bone dry.”
“Crew showed up on time, laid down protection on every floor, finished in two days. Wrote me a written warranty I could read without a lawyer.”
“Three other contractors quoted excavation. Quali-Dry did interior drainage for a third of the price. Basement's been dry through two springs.”
