Case Study - External Repairs and Maintenance

Service: Building Surveying, Contract Administration & Project Management
Sector: Residential (Mixed-Use)
Location: Hampstead, London

We were appointed to investigate and resolve ongoing issues relating to roof leaks and damp penetration at a residential block of flats in Hampstead, with commercial units located at ground floor level.

The client required:

• Accurate diagnosis of water ingress and building defects
• A robust repair strategy to address both roof failure and external fabric defects
• Justification of works and costs to service charge consultants
• Full management of works within a mixed-use, occupied building

1. Defect Diagnosis & Investigation
We undertook detailed inspections to identify the root causes of:

• Persistent roof leaks
• Damp penetration affecting internal areas

Our assessment confirmed the need for full roof replacement, alongside targeted external repairs to prevent further ingress.

2. Scope Development & Justification
We prepared a clear and comprehensive specification of works, including:

• Complete roof replacement
• Repairs to brickwork and defective pointing
• Associated external fabric repairs

Given the involvement of commercial tenants, we worked closely with service charge consultants, providing technical justification and cost rationale to support the proposed works.

3. Tendering & Procurement
We produced detailed tender documentation and issued to suitable contractors to obtain competitive pricing. Following tender analysis, we advised on contractor appointment to ensure value and quality.

4. Contract Administration & Delivery
We managed the project through to completion, including:

• Overseeing the full roof replacement
• Monitoring external repair works (pointing and brickwork)
• Ensuring quality and compliance with the specification
• Managing programme and sequencing of works

5. Stakeholder Liaison
The building remained fully occupied throughout the works. We:

• Liaised with residential and commercial tenants
• Coordinated access and managed expectations
• Provided clear communication to minimise disruption

6. Cost Control & Certification
We maintained full commercial oversight, including:

• Monitoring costs and managing variations
• Certifying interim payments and final completion
• Ensuring works were delivered in line with agreed budgets

• Diagnosis of complex roof leaks and damp penetration
• Full roof replacement and external fabric repairs
• Engagement with service charge consultants for cost justification
• Mixed-use building with residential and commercial tenants
• Detailed specification, tendering, and contract administration

• ✔ Successful resolution of water ingress issues
• ✔ Full roof replacement completed to a high standard
• ✔ External brickwork and pointing defects repaired
• ✔ Works justified and agreed with service charge stakeholders
• ✔ Minimal disruption to occupants during delivery
• ✔ Project delivered, certified, and closed out efficiently
