Moisture Probe Monitoring and Plaster House Maintenance for Monolithic Cladding
Keep Monolithic Houses Safe and Dry
All houses require regular maintenance but plaster house maintenance is different. Monolithic cladding, badly treated timber, no cavity system and some poor building skills mean that you need to find and resolve problems quickly using moisture probes wherever leaks may develop.

If you don’t take the time to prepare a home with monolithic cladding for sale, there is a high risk of low offers or deals falling through.

Plan to achieve a higher price and smoother sales process by proving that your house is safe and dry, and by fixing the problems that make your home look risky to buyers and building inspectors.

Ian at Moisture Detection clearly has a wealth of knowledge on all topics related to building weather tightness. More importantly he had the knowledge on all the options for addressing the leaks. Those options were discussed with me and I agreed on a scope of work. Moisture Detection undertook work, at a reasonable price, to improve weather tightness (windows, barge boards, roof flashing), remove gib and inspect some areas, and inject RotStop throughout the house. Some repairs were also conducted by a registered builder. Now with annual moisture readings I have been able to correct any causes of high moisture readings and have confidence in the condition of my plaster clad home. I have no hesitation in recommending Moisture Detection to any current or potential plaster home owner.


Our clients are able to negotiate a better buying price on their home with monolithic cladding,  then make them weatherproof and safe using our patented Moisture Probe technology, which pin-points the problems for more cost effective repairs and detects future leaks.
