Halo Water Proofing has been the London area's go-to call for Vapor Barrier Installation because we answer the phone, show up on time, and stand behind the work.
We're Halo Water Proofing — a OH-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through London-area foundations, and exactly how to stop it.
Every technician on our London crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our London technicians hear about most often before an inspection.
Odor is often the first sign London customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your London foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your London lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of London call we prioritize fast.
These signs upstairs are often the last clue London homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in London every day.
Storm season in London, OH means our emergency line gets busy fast — we triage calls by severity so active flooding at your London address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in London, OH push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in London after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →For London properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our London crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in London carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your London job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
A local dispatch model means the technician who answers questions about your London job is the same one who shows up to do it.
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
If your London basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most London, OH carriers ask for before approving a claim.
