What do you need?

What we see in Ballwin

  • Sloped lots and walkout basements send stormwater toward the uphill wall, so drainage fixes often matter most.
  • Ask whether a crack comes from settling, soil pressure or water, and how the fix matches the cause.
  • Make sure downspouts discharge well away from the house before paying for an interior system.

Questions to ask a foundation & basement waterproofing contractor

  • What's causing the problem, and how does your fix address that cause?
  • Do you recommend an independent structural engineer's evaluation?
  • Which cracks are cosmetic and which are structural?
  • What does the warranty cover, for how long, and does it transfer to a buyer?
  • Will finished walls or flooring need to come out?
  • Are you licensed where required and insured?
