DAMP AND TIMBER SURVEYS IN NORTH WALES
Need an independent damp and timber survey in North Wales? AMS SURVEYS investigates the cause of damp, mould and timber decay before remedial work is specified. Our Building Surveyors assess the building as a whole, distinguishing between condensation, penetrating damp, plumbing or drainage related moisture, bridging and genuine rising damp, while also checking accessible timbers for decay or infestation.
DAMP AND TIMBER SURVEYS IN NORTH WALES
A targeted damp and timber inspection in North Wales is particularly useful when:
a mortgage valuation, Level 2 or Level 3 survey recommends further investigation
there is visible staining, mould, salt contamination or a persistent musty smell
floors feel soft, springy or uneven, or accessible timbers show signs of decay
previous damp proofing has not resolved the problem
you are buying an older, altered or traditionally constructed property
We do not start from the assumption that a damp proof course is required. The inspection considers construction, external defects, ventilation, drainage, internal moisture sources and timber condition so that recommendations address the likely cause rather than simply the symptom.

COMMON DAMP AND TIMBER ISSUES WE IDENTIFY IN NORTH WALES
Coastal exposure, wind driven rain and traditional stone construction are important considerations across North Wales. Older cottages, holiday accommodation and historic buildings can also be affected by intermittent heating, incompatible finishes and reduced ventilation.
Our survey focuses on identifying the moisture mechanism and the building defect or environmental condition behind it. Where appropriate, this may include penetrating damp from roofs, chimneys, walls or rainwater goods, condensation and ventilation imbalance, plumbing or drainage leaks, bridging of damp proof courses, sub floor moisture, wet rot, dry rot risk and evidence of wood boring insects.
The aim is to provide clear, proportionate repair advice and identify where further opening up, testing or specialist contractor input is actually justified. For traditional or historic buildings, recommendations should also consider compatible materials and breathability rather than defaulting to impermeable treatments.

NORTH WALES DAMP SURVEY FAQS
Does coastal exposure increase damp risk in North Wales?
Yes. Wind driven rain in coastal areas such as Llandudno and Conwy can increase the likelihood of penetrating damp, particularly where external maintenance is poor or walls are highly exposed.
Are stone cottages in North Wales prone to moisture problems?
Traditional solid wall buildings can behave very differently from modern cavity construction. Breathability, pointing materials and ventilation all influence moisture performance.
Can you inspect holiday lets and second homes in North Wales?
Yes. We regularly survey holiday accommodation and second homes where intermittent heating and occupation can contribute to condensation and mould risk.
