Building Surveys
Our comprehensive building surveys assess residential property condition across Cornwall. Chartered surveyors identify structural issues, material deterioration, and maintenance requirements using RICS standards. Reports provide detailed recommendations for remedial action and property valuation.
Mundic Testing
Specialist Mundic testing identifies mining aggregate deterioration in Cornish properties. Our RICS-approved process includes core sampling, petrographic analysis, and classification according to mortgage lender requirements. We provide Stage I-III assessments with clear pass/fail determinations.
Questions
What is Mundic testing?
Mundic testing assesses concrete containing mining aggregates that may cause structural deterioration. We perform core sampling and laboratory analysis to determine property safety and mortgage eligibility.
Why do I need a building survey?
Building surveys identify structural issues and maintenance requirements before property purchase. Our detailed reports help negotiate prices and plan future repairs according to RICS standards.
Which areas do you cover?
We operate throughout Cornwall including Penzance, St Ives, Camborne, and Isles of Scilly. Remote location services available upon request with additional travel arrangements.
How long does Mundic testing take?
Stage I assessments typically complete within one day. Laboratory analysis takes 5-10 working days. Complex Stage II/III assessments require additional time for comprehensive evaluation.
Are your surveyors qualified?
All assessments conducted by RICS-accredited chartered surveyors with specialist Mundic testing certification. Our team contributes to industry guidance development and lender approval schemes.

Report
Customer service and interpersonal skills very poor, defensive, arrogant, does not listen, talks over you and publishes on google that there is a mundic report on your property even when there's no mundic in your property and the report is 100% negative, leading any lay person to believe your property has mundic. This is very disingenuous behaviour and gives surveyors and RICS a bad name. To illustrate Wayne's Tieken general attitude during our conversation, in his own words Wayne said, 'it's my report I can do what I like with it'.
Clearly as the proprietor Wayne answers to no one, except that is the CUSTOMER, so BUYER BEWARE and know there are many other mundic surveyors available. By publishing such information Wayne Tieken is obviously trying to sell the report again for a quick buck. For what good it will do, I am going to bring this matter to the attention of RICS
