Cracked walls in Armadale
The eastern edge of the coastal plain has more clay in the ground than the sandy western suburbs. Reactive clay swells when it's wet and shrinks when it dries out, so houses here can move with the seasons. That shows up as cracks that open in summer and close in winter. Crack stitching, combined with fixing drainage around the footings, deals with it for good.

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).
