Get your home PROTECTED before wet weather arrives!

Callow Waterproof Inc. has been your trusted name in basement waterproofing since 1951. We are the oldest and most respected family owned & operated waterproof company here in the Mahoning Valley. Just ask any of our customers. Who doesn't want a HEALTHY, DRY, MOLD-FREE home? Waterproof now to get the most for your money!

All waterproof systems are not created equal. We are best known for our EXTERIOR SYSTEM, which includes protecting all wall surfaces underground, and keeping all water and moisture out of your basement and walls. No moisture in the walls equals no mold growth! Cold, damp air is prevented from entering the basement, and heat loss is reduced to save you money. Once we seal your wall surface, it's no longer necessary to run a dehumidifier or air ventilator—saving you money on electric bills too!

Call us for an inspection and compare, before you pay too much!

Stop and visit us at our Niles Office.

What makes us stand out from the competition!

  • We offer the ONLY "money back guarantee" in the business, should we not be able to solve your issues.
  • The "owner" does each inspection, oversees the crew work, and ensures your satisfaction before you pay your bill
  • Craig Callow has 35 + years diagnosing & remedying all types of foundation and water problems, four years as a local building inspector, and is considered an "expert."
  • You pay ONCE! No monthly or annual maintenance fee charged.
  • We offer "free inspections" during regular business hours, on homes you reside in (a nominal fee applies for rentals, condo's and/or homes listed for sale).
