How do service areas work?
Each town listed is covered by insured waterproofing and foundation contractors who take Holdfast requests for its ZIP codes. They are service areas, not branch offices, and you'll be told on the call if your ZIP isn't covered.
What changes from town to town?
Youngstown, Warren, Niles and Campbell have many early-1900s homes on sandstone, brick or hollow block foundations. Boardman, Austintown, Howland and Canfield have mid-century block basements that bow under clay soil pressure. Columbiana County towns such as Salem, Lisbon and East Liverpool add hillside drainage and old stone foundations. Everywhere, the March–April thaw is peak basement-water season.
How do licensing and permits work?
Ohio doesn't license waterproofing contractors statewide, so insurance, local references and written, transferable warranties matter. Excavation, structural wall repair and some drainage tie-ins can require city or township permits.
Not sure your street is covered?
Call and give your ZIP. You'll be told honestly if it isn't covered.
By calling, you agree to be connected with an independent waterproofing contractor, who may call or text you back about your request at the number you call from. Calls may be recorded for quality and routing. Consent is not a condition of any purchase; you can opt out at any time, and message and data rates may apply. Privacy policy.
