Call for Emergency Service →Hairline cracks are how most Monmouth Junction basements start leaking. We use polyurethane injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Monmouth Junction after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
