Services
Party Wall Matters
We advise on rights and obligations under the Party Wall etc. Act 1996, preparing schedules of condition and Awards for works. Our services include serving notices, resolving disputes, and ensuring compliance with legal frameworks. Clients benefit from clear documentation and expert arbitration to prevent and address damage claims.
Defect Investigation
Specialising in diagnosing issues like water ingress, dampness, and subsidence, we conduct detailed inspections and provide photo-illustrated reports. Our solutions include opening-up works, laboratory testing, and monitoring to identify root causes. Clients receive actionable recommendations for remediation and long-term property health.
Camera Mast Surveys
Using 15-metre camera masts, we perform high-resolution aerial surveys for inaccessible areas. This method ensures precise defect detection without drone restrictions. Ideal for built-up zones, our surveys support roofing assessments and structural evaluations with detailed visual data.
Roofing Works
We manage re-covering projects for flat and slate roofs, including occupied properties. Services span feasibility studies, specifications, and contract administration. Clients receive durable solutions addressing water ingress and extending roof lifespan, as demonstrated in Wimbledon and Hampstead case studies.
Dilapidations
We negotiate dilapidation claims between landlords and tenants, preparing schedules and advising on maintenance. Our proactive approach minimises liabilities and protects property assets through condition assessments and compliance strategies during and after lease terms.
