Damp survey and diagnosis


Penetrating damp occurs when water infiltrates your property through external defects or internal issues, resulting in damage to your walls, ceilings, and furnishings. To effectively combat penetrating damp, it’s crucial to identify the source of water ingress and implement appropriate repairs. Our qualified damp proofing surveyor can assess your property to determine the cause of the dampness and the extent of required repairs.
Once the source of the dampness is identified, our damp proofing specialists will remove the affected material and apply a physical waterproofing membrane to expedite the drying process. Furthermore, external issues must be addressed, which may involve coating the exterior wall with a chemical water repellent to ensure water remains outside your property, protecting your living space from further damage. Prompt and effective management of penetrating damp is instrumental in preserving your home’s structural integrity and comfort.

Wet rot is an umbrella term for several forms of fungal species, most commonly Coniophora puteana and Choanephora cucurbitarum. Often mistaken for dry rot, it softens and weakens the structural integrity of timber by feeding off its moisture and nutrients.
Signs of wet rot in your timber structures include:
• Soft and spongy timber
• Musty, earthy odours
• Localised fungus growth
• Darkened timber surfaces
• Shrinking of wooden structures
Wet rot is caused by excess moisture in timber stored for long periods of time. To effectively remove the fungus, it’s imperative to identify the source of moisture which, in most cases, is caused by:
• Condensation
• Faulty plumbing
• Blocked guttering
• Penetrating damp
• Roof defects
