Halo Water Proofing is a NY-licensed Exterior Waterproofing company that treats every Alexander job like it's the only one on the schedule.
Our Alexander 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 Alexander 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.
📞 +1-866-476-1348Most Alexander calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Alexander homeowners notice, well before any water is visible.
Small cracks in a Alexander foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A Alexander sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Alexander customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Alexander property, chances are we've already fixed something similar nearby this month.
A flooded Alexander basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →We seal active Alexander foundation cracks with epoxy 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.
Talk Drainage Options →A damp Alexander 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 handle below-grade waterproofing for Alexander property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Alexander customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Alexander property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Alexander horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
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.
We'd rather earn a repeat Alexander customer with an honest fix than push a system you don't need.
We can supply the documentation most carriers ask for before approving a Alexander claim.
Word of mouth is still how most Alexander 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."
"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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Alexander technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
