Cracked walls in Joondalup
On sandy blocks, cracking usually comes from fill that wasn't compacted properly, plumbing leaks washing sand out from under footings, or limestone retaining walls moving. We find the cause, stabilise it, and stitch the cracks so they don't come back.

How we repair it
Every job starts with a free site visit. We find the cause of the movement, then give you a written specification and quote. Most cracks are repaired with Helifix crack stitching: stainless steel HeliBars bonded into the mortar joints, then repointed or rendered to match. Where needed we also replace lintels or wall ties, or underpin the footing. As a Helifix Approved Installer, we offer a 10-year indemnified guarantee on most Helifix repairs (T&Cs apply).
