Clear about our role
This page's job is narrow: collect Charleston-area project inquiries and route them to an independent local provider. It doesn't perform work itself and makes no claim to a license, an office, a crew, past projects, awards, or a guaranteed response time.
What homeowners should verify
Before authorizing anything, a Charleston-area homeowner should independently confirm the provider's identity, applicable licensing, insurance, permits, the written scope, warranty terms, the schedule, and payment structure.
Why local context matters
Measure the moisture coming through the slab before choosing a product, because with the water table this close to the surface the vapor drive is continuous and a coating over an untested slab is the standard way this work fails. Establish the age of the pour, since older slabs frequently went down with no vapor retarder at all. And check the parcel's flood elevation: on a low-lying property the ground level may not be habitable space under the floodplain rules, which changes what the room can be used for and therefore what its floor is worth.
What official local sources add
Preservation review governs exterior appearance and does not ordinarily reach an interior slab, so for this trade the relevant record is the flood map rather than the district rules. A ground-floor or garage slab on a parcel with mapped flood exposure has a history worth knowing before a coating is specified, because a slab that has taken water before will likely do so again and that predicts the moisture the coating has to survive. In some low-lying properties the ground level is not habitable space at all under the floodplain rules, which changes what the room can be used for and therefore what should be spent on its floor.
