QUESTIONS · ANSWERED
Basement Waterproofing questions, answered.
How do I know if I really have a water problem or just humidity?
A real water issue shows up after heavy rain — water at the floor edges, dark stains on the walls, or seepage at the corners. Pure humidity is musty smell, occasional summer dampness, and clammy walls without visible water. We can tell which it is during a 30-minute site visit.
How long does the typical fix take?
Interior drain tile + sump installation: 2-3 days. Exterior membrane waterproofing: 4-7 days including perimeter excavation and landscape restoration. Sump pump swap-out: same-day. Foundation crack repair: 1 day per major crack.
What kind of warranty do you offer?
Interior drain tile + sump systems: 25-year transferable warranty. Exterior membranes: 10-15 years. Foundation crack repair: 5-10 years depending on the crack type. Drainage repairs: 5 years. We put the warranty in writing on the contract.
Will the work damage my landscape?
Interior work doesn't touch the yard at all. Exterior membrane work requires perimeter excavation — usually 3-5 feet out from the foundation. We hand-dig around irrigation, photograph plantings before we start, and restore the landscape on the same crew rotation. Plant-replacement guarantee covers any losses.
Do you offer financing?
Yes — for projects $5,000 and up. Most homeowners qualify for 12 or 24-month deferred-interest plans through our lending partner. Application takes 10 minutes online, approval is usually same-day.
