Our Lannon crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.

Odor is often the very first clue Lannon homeowners notice, well before any water is visible.

Every Lannon job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
