Services
Subsidence Repair
Our subsidence repair service addresses ground movement issues through comprehensive site investigations and engineered solutions. We diagnose causes including heave, landslip, and foundation settlement, implementing traditional underpinning, pressure relief systems, and structural reinforcement. With 35 years' expertise, we provide lasting repairs backed by detailed moisture monitoring and 12-year insurance guarantees.
Foundation Design
We design and construct tailored foundation systems for new builds and remedial projects. Our services include traditional strip foundations, piled foundations, and reinforced concrete rafts. Each solution incorporates site-specific geotechnical analysis and vegetation impact assessments, with all installations covered by 12-year insurance-backed guarantees for structural integrity.
Property Restoration
Our property restoration service specialises in post-fire and flood recovery, returning properties to pre-loss condition. We coordinate drying processes using professional dehumidification equipment, conduct structural repairs, and manage insurance claims negotiations. Our nationwide team handles complete rebuilds including plumbing, electrical systems, and decorative finishes with minimal client disruption.
Underpinning
We provide traditional and specialist underpinning solutions for properties experiencing structural movement. Our methods include mass concrete underpinning, helical piling, and pressure relief tunneling. Each project follows detailed structural assessments to determine appropriate reinforcement strategies, ensuring long-term stability with comprehensive warranty coverage.
Insurance Claims Support
We assist clients with insurance claim processes for structural damage, working directly with loss adjusters and insurers. Our services include damage assessment reports, repair cost scheduling, and claim negotiation support. This streamlined approach ensures efficient claim resolution while maintaining high repair standards throughout the restoration process.

Did an excellent job rebuilding our wall, including going to extra trouble to blend in with older brickwork. Left the site spotless. Remy the bricklayer was very considerate and went out of his way to minimise disruption during 4 days he was here.

Jun 2017 This review is only my personal experience of one set of work with Colwins so I have no idea what they may be like with other work. To date our experience has been absolutely shocking. Colwins were contracted via our insurers to do some work on our house following some subsidence. Part of the work included the filling of a crack in the front wall of our house. Most of the work was done but the crack wasn't repaired. This was over 4 YEARS ago and we have been chasing them ever since. Every time my wife phones they take note, promise to have a look into it and find someone to come around
