About Us


Seth & his Family

Drainage Masters emerged in response to the wake-up call of the Great Flood of '96, which illuminated the absence of specialized drainage or stormwater companies catering to residential issues. Seth Kenworthy, the owner of Drainage Masters, has harbored a lifelong fascination with drainage and hydrology. Channeling his passion into his business, Seth is delighted to contribute to the local community by addressing this crucial need. Transitioning into this field was only a natural extension of his interests, allowing Drainage Masters to fulfill its mission of providing effective solutions and support to homeowners grappling with drainage challenges.
