Structural Wall Tying in Dorset
Structural wall tying is essential when cavity walls begin to separate — a common issue in Dorset properties affected by subsidence, corroded wall ties, or poor original construction. Our wall tying service uses stainless steel helical ties to reconnect inner and outer wall leaves, restoring structural stability.
Failed wall ties are particularly common in properties built between the 1920s and 1980s, where galvanized steel ties were used that are now corroding. Signs include horizontal cracking along mortar courses, bulging walls, and gaps between walls and window frames.
We offer both remedial wall tie replacement and new tie installation, using mechanical and resin-bonded systems suited to your wall construction. All work is carried out to BRE guidelines and comes with full documentation.

Frequently Asked Questions
How do I know if my wall ties have failed?
Common signs include horizontal cracks along mortar joints, bulging or bowing outer walls, and gaps appearing around window and door frames. A wall tie survey using a metal detector and borescope can confirm the condition of your existing ties.
How many wall ties does a house need?
Typically 2.5 ties per square metre of wall area, with additional ties around openings. For a standard semi-detached house, this could mean 200-400 ties depending on wall area. We calculate the exact requirement during our survey.
What do replacement wall ties cost?
Wall tie replacement costs depend on the number of ties needed and accessibility. We provide detailed quotations following a survey. The cost is far less than dealing with the structural damage that failed ties can cause.
How long does wall tie replacement take?
Most residential wall tie replacements are completed in two to four days. The work is carried out from outside, so disruption to your daily routine is minimal.
Can wall tie failure cause subsidence?
Wall tie failure itself doesn't cause subsidence, but it can cause similar symptoms — cracking and wall movement. It's important to correctly diagnose whether the issue is tie failure, subsidence, or both, which our structural assessments will determine.
Do you remove old wall ties?
In most cases, old ties are left in place and new stainless steel ties are installed alongside them. Removing old ties can cause additional damage. We isolate any corroding ties to prevent further expansion cracking.
