Montgomery County runs from Main Line homes in Ardmore to the office parks of King of Prussia and Plymouth Meeting, older river towns like Norristown and Conshohocken, and the newer developments around Lansdale. Water losses look different in each: slab leaks and finished basements in the suburbs, Schuylkill and creek flooding in the river towns, and roof and sprinkler failures in commercial buildings.
Onyx provides water damage restoration, mold remediation, fire and smoke cleanup, storm response and rebuild across the county for homeowners and businesses.
