Delaware County sits right against West and Southwest Philadelphia, and the housing looks like it: rowhomes and twins in Upper Darby, Drexel Hill and Havertown, older singles in Media, Swarthmore and Springfield, and industrial and commercial property toward Chester and the river. The losses are the same ones we handle in the city, and the drive is short.
Onyx provides water damage restoration, mold remediation, fire and smoke cleanup, storm response and rebuild across Delaware County for homeowners and businesses.

Mold remediation in Delaware County
Below-grade basements, shared party walls and older plumbing make mold a frequent second problem after a water loss that was dried with fans only. Onyx finds the moisture, contains the area, removes the growth and the material it colonized, and fixes the cause.
