Halo Water Proofing has been the Gaithersburg area's go-to call for Basement Waterproofing because we answer the phone, show up on time, and stand behind the work.

We don't send apprentices to figure it out on your dime. Every Gaithersburg job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.

π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our Gaithersburg technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look β they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your Gaithersburg foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time β usually during the next big Gaithersburg storm.
A bowing basement wall is a structural concern in addition to a water one β this is the kind of Gaithersburg call we prioritize fast.
These signs upstairs are often the last clue Gaithersburg 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 Gaithersburg every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Gaithersburg emergency crews remove the water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service βFreeze-thaw cycles in Gaithersburg, MD 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 βAlready have a sump pump that's failing or too small for your Gaithersburg lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume β not the cheapest unit on the truck.
