Halo Water Proofing started small in the Somerville area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Somerville technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Somerville crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
