Mold from a damp basement isn't just ugly — it's dangerous.
Hidden mold spores from a wet basement are linked to asthma attacks, chronic coughs, allergies and serious respiratory illness — especially in kids, seniors and anyone with a weak immune system. Every day you wait, it spreads further into your walls, insulation and air.
"We thought a hairline crack was nothing. They injected it for $650 and showed us how it would have cost ten times that in five years. Honest people."

Frequently Asked Questions
What does foundation repair cover?+
Crack injection, parging repair, structural reinforcement (carbon fibre or steel), and re-waterproofing of damaged sections. We'll tell you exactly what's needed and what isn't.
How urgent is a foundation crack?+
If it's leaking, very. Even a hairline crack widens every freeze-thaw cycle and rusts any rebar inside. A $600 fix today can become a $20,000 fix in 5 years.
Are horizontal cracks worse than vertical?+
Usually yes. Vertical cracks are typically shrinkage. Horizontal cracks can indicate structural pressure from outside soil and need professional assessment immediately.
What does foundation crack injection cost?+
$400–$900 per crack, workmanship warranty. Severe structural repairs can run higher and may require exterior excavation.
