📞 +1-866-476-1348Most Pomona 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 Pomona homeowners notice, well before any water is visible.
Small cracks in a Pomona foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Peeling paint near the floor upstairs is one of the last signs Pomona homeowners connect to a basement problem.
No two Pomona basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Pomona 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 Pomona 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.
