Basement waterproofing in Westerville, Ohio

Alum Creek, glacial clay and a lot of 1960s–2000s basements.

Westerville straddles the Franklin–Delaware county line, with Alum Creek running north to south through the middle of town. Much of the city's housing went up between the 1960s and the 2000s, so you'll find poured concrete basements, concrete block basements, and a fair number of homes where a sump pump was an afterthought. Add the slow-draining glacial till that underlies most of the area, and spring is reliably busy for waterproofing contractors here.

What Westerville homeowners most often report

Near the creeks

Homes close to Alum Creek or its tributaries may have a higher water table and may sit near mapped floodplain. Waterproofing manages groundwater and seepage, but it isn't flood protection against rising creek water. If you're near the creek, check your property on FEMA's flood map and talk to your insurance agent about flood coverage. Standard homeowners policies typically exclude flood.

Permits and HOAs

Permit requirements for drain systems, sump discharge lines and structural wall repairs vary. The City of Westerville handles permits inside city limits, while homes in the unincorporated parts of Blendon, Genoa or Orange townships go through the county. A reputable contractor will tell you whether a permit is needed and pull it. If you're in an HOA, check the rules before any exterior regrading or discharge line runs across the yard.

Getting a useful inspection

Before the contractor comes, note which walls get wet, how soon after rain, and whether it happens with snowmelt. Clear storage away from the walls so they can be seen. Ask the inspector to explain the cause in plain language and to separate "must-do" items from "nice-to-have" ones in the written quote.
