A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A Towson sump pump that never rests is usually undersized or nearing the end of its life.

Get Emergency Help βWe seal active Towson foundation cracks with hydraulic cement injection β stopping the leak at its source instead of patching the surface.
Ask About Crack Repair βAlready have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
