From a hairline crack to a fully soaked crawl space, our Radnor crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in OH · 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.
Our Radnor crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Radnor 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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Radnor crews hear about most.
Odor is often the very first clue Radnor 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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Radnor sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Radnor schedule.
Peeling paint near the floor upstairs is one of the last signs Radnor homeowners connect to a basement problem.
Whatever's going on with your Radnor property, chances are we've already fixed something similar nearby this month.
A flooded Radnor basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →We seal active Radnor foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Radnor after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Radnor basement floor at all.
Talk Drainage Options →A damp Radnor 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 →We can phase larger Radnor commercial projects around business hours or tenant schedules so operations keep running.

A real technician asks the right questions to understand what's likely happening at your Radnor property before anyone drives out.
A Radnor technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Radnor horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Radnor customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Radnor contract we sign.
