From a hairline crack to a fully soaked crawl space, our Leonardtown crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in MD · 24/7 dispatch
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Leonardtown 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 Leonardtown 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.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Leonardtown homeowners.
Odor is often the very first clue Leonardtown homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Leonardtown foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
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.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Leonardtown crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in Leonardtown tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Leonardtown after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →Some Leonardtown properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Leonardtown crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Leonardtown jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.

Every Leonardtown job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
