Party Wall Matters
We provide comprehensive Party Wall services under the 1996 Act, including serving notices, preparing Awards, and resolving disputes. Our expertise covers boundary walls, structural alterations, and excavation works. Clients receive detailed schedules of condition to protect against damage claims, alongside expert guidance on legal obligations.
Defect Investigation
Our defect investigation identifies causes of water ingress, subsidence, and structural failures. We conduct site inspections, laboratory testing, and movement monitoring to deliver actionable repair strategies. Services include photographic reports, remedial specifications, and contract administration to ensure lasting solutions for residential and commercial properties.
Roofing Works
We specialise in flat and slate roof refurbishments, including re-covering and waterproofing. Our process involves assessing existing conditions, specifying materials, and managing contractors to ensure compliance with building regulations. Projects are completed with minimal disruption, even in occupied buildings, guaranteeing long-term performance.
Dilapidations
We assist landlords and tenants with dilapidations claims, preparing schedules of condition and negotiating settlements. Our services include pre-lease advice, planned maintenance strategies, and terminal inspections to minimise liabilities while protecting property assets throughout lease terms.
Camera Mast Surveys
Using 15m camera masts, we conduct high-resolution aerial surveys in areas inaccessible to drones. This method enables precise defect analysis of building facades and roofs, particularly in urban zones with airspace restrictions. Results inform targeted repair programmes and condition assessments.
