Halo Water Proofing has been the trusted call for Exterior Waterproofing across Somerville because we answer the phone, show up when we say, and stand behind the work.
Background-checked Somerville technicians · 24/7 dispatch
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.
We've worked on foundations from decades-old Somerville 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.
Talk to a real Somerville technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Somerville homeowners.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Somerville foundation rarely stay small — seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your Somerville foundation wall right now.
A Somerville sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Somerville property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Somerville emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →We seal active Somerville foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
