Excessive subfloor moisture can cause rising damp, wood rot, problem odours and pest infestation. If untreated, subfloor moisture may result in the growth of moulds and mildew, causing serious health issues. The affordable solution is an economic long lasting subfloor ventilation system installed by Doctor Damp.

Our consultants and technicians are trained to design and install subfloor ventilation systems to remove ground moisture from underneath raised floors. Duct openings will be positioned at problem locations so that damp air may be drawn off and externally exhausted.

Insulated ducting is used for improved acoustic performance and special imported high moisture resistant (PVC fume control duct) PFC duct is used to improve durability and longevity in damp underfloor environments. Timers, mounted next to the subfloor access hatch for easy service and maintenance, will be installed so that pumps run only during daylight hours.
