Six ways buildings tell you something is wrong.
Cracks, leaning stacks, sagging lintels and bowing walls are rarely the problem itself. They're the symptom. Our surveys identify the cause first, then match the repair to the building, from Victorian terraces to listed properties around Blackheath.
Structural repairs, matched to the defect
Every entry below is a distinct discipline with its own diagnosis and repair method. We don't offer one fix for every crack. Start with the one that matches what you're seeing, or get in touch and we'll help you narrow it down.
Cracks & Movement
Recurring, stepped or widening cracks, bowing walls, separation around openings. Rather than patching the surface, we investigate the root cause: thermal movement, subsidence, failed wall ties or foundation settlement. We deliver a repair built to last, not just to hide.
Lintels & Masonry
Failed supports, displaced brickwork, spalled masonry and unstable facades. We carry out a structural assessment, make the area safe, and replace or reinforce lintels so the load above windows and doors is properly carried again.
Chimneys & Parapets
Loose copings, leaning stacks, failed pointing and other high-level safety concerns aren't obvious from the ground. We carry out a full inspection at height and repair or rebuild before a small defect becomes a falling-masonry risk.
Structural Roofs
Roof spread, failed timbers, storm damage and roof movement often show up as cracking or bowing in the walls below. We coordinate a structural response that addresses the roof and its knock-on effect on the walls it sits on, not just the visible damage.
Traditional Fabric
Older and listed buildings move and weather differently than modern construction. We work with lime mortar, historic brick, slate and lead, using conservation-sensitive methods so the repair supports the structure without erasing its character.
Party Walls
Defects that sit on or near a shared structure bring in more than bricklaying — neighbours, access and legal notices all come into play. We handle the structural repair and can advise on the Party Wall process alongside it.
Loose masonry, sudden movement or unstable structure.
Not sure which one fits?
Most jobs touch more than one category above — a failed lintel often shows up as a crack, a chimney problem often starts as roof movement. Here's how we get from "there's a crack" to a fixed wall.
Free assessment
A surveyor visits, photographs and measures the defect, and asks about when it appeared and how it's changed.
Diagnose the cause
We identify what's actually driving the movement — not just where it's showing.
