Building Performance, Damp, Mould & Ventilation Specialists
Ray & Co Surveyors was established to raise the standard of building surveys, retrofit assessments, and damp & mould investigations.
Too many property decisions in the UK are still made on assumptions, generic reports, or sales-led advice. We exist to do the opposite: to provide clear, evidence-based assessments that clients can trust, whether they are homeowners, landlords, managing agents, or retrofit professionals.
Every survey we carry out is grounded in current British Standards, Building Regulations, and recognised best practice, not opinion or guesswork.
What We Stand For
Confidence
We give our clients confidence by explaining what is actually happening in their property and why. No scare tactics. No vague conclusions. Just clear findings, supported by data, inspections, and standards.
Trust
