Dry Rot
Wet Rot
Wood Worm
Dry Rot

Dry Rot indications vary immensely from discolouration to dry cracked timbers, red/orange dust, grey cobweb like strands or cotton wool/mushroom like growths on the wood combined with a musty odour. 

Wet Rot

Wet Rot indications vary from a damp musty smell to discolouration and softening of the floor timbers to finding fungal growth.

Wood Worm

Woodworm refers to the larvae of any wood-boring beetle, rather than one particular species. All invade and consume wood, and then leave when they have reached maturity.

Cavity Wall Ties

Rising damp occurs when the breakdown of the original damp proof course allows ground moisture to rise up through the brickwork soaking the wall coverings (render or plaster coatings) which appears in your property as a crystalline salty looking contamination or just a simple water staining or bubbly paint issue.

Ventilation & Condensation

Black mould and condensation can be a real problem in many homes. It looks awful, damages your décor and belongings and left for too long can be harmful to your health.

Cavity Wall Ties

Cavity wall ties are found in properties with cavity constructed brickwork and are installed to ensure the two courses (internal and external) are fully bonded together strengthening the walls. Over time due to moisture they can deteriorate weakening the structure which causes cracks bowing or dropped brickwork.

The works carried out by Ross and his team were of a good standard. We had some damp proofing added and also some rendering to numerous parts of the house. Overall I'd highly recommend Ross and his team and we'll be definitely using them again when required.
