Investigation & Surveys
At Notion4, we help landlords and letting agents uncover the cause of property issues before they become costly problems.
Whether you’ve noticed signs of damp, leaks, cracks, or structural wear, our experienced team provides detailed surveys, photographs, and professional recommendations for repairs.
A Complete Property Maintenance Partner
From everyday repairs to full refurbishments, NOTION4 delivers dependable property maintenance solutions for all types of clients.
We combine multi-trade expertise with digital reporting and exceptional service — ensuring every job is completed efficiently, safely, and to specification.
Why Investigation Matters
Property problems don’t fix themselves — and small signs can quickly turn into major issues if left unchecked.
Our investigation and survey service gives landlords and letting agents clear insight into what’s happening inside their properties, helping prevent damage, disputes, and unnecessary expense.
We pride ourselves on providing independent, practical advice, not sales-driven fixes.
We help identify:
- Leaks and water ingress
- Damp and mould sources
- Structural cracks and movement
- Condensation and ventilation issues
- Heating and plumbing faults
- Electrical problems and compliance risks
