📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Fairfax crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Fairfax crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Fairfax sump pump that never rests is usually undersized or nearing the end of its life.

These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Fairfax crews handle most.
