Property Owners & Managers

“Water damage” – two words every property manager or owner dreads.

The cost, liability, and the headaches associated with never-ending repairs caused by water leakage around the toilet into the sub-floor can be prevented. The Culwell Flange is the only flange design that seals to the floor. This creates a protective water-tight barrier that saves you rental down time, and reduces liability.

Fix it and forget it with the Culwell® Flange:

  • Reduce downtime – reoccurring water damage prolongs repair time. Seal it and save time.
  • Reduce cost for repairs – you could spend $100s or $1000s replacing drywall, plumbing, flooring…or, you could fix it and forget it.
  • Eliminate tenant turnover – chronic leaks and water damage can send tenants (and your income) through the floor.
  • Reduce liability from water damage – water can leak through ceilings and onto your tenants property, costing you hefty insurance premiums and tenant turnover.
