Halo Water Proofing has been the trusted call for Interior Drainage System across Oakland because we answer the phone, show up when we say, and stand behind the work.

Halo Water Proofing started small in the Oakland area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Oakland technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Oakland homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
