All posts, Condensation, Energy Efficiency / Insulation Improvements

Thankfully it’s not often we’ll come across retrofit spray foam insulation however, it is still important to understand its impact as there are still a large amount of properties who’ve employed this insulation technique in the past.

Spray foam insulation is a polyurethane spray applied foam which sets to form an insulating barrier. It’s available in two different types open cell and closed cell.

EXPLAINED: Moisture Content Analysis using the Gravimetric Process

March 15th, 2019

All posts, Damp / Rising Damp / Damp Proofing /, Surveying

Gravimetry is basically the quantitative technique which measures mass or a change in mass during an analytical process. For example, we’ve probably all unknowingly undertaken this ourselves when stepping on scales during a dieting regime or when in training. Effectively we’re measuring our own body mass and comparing this weight loss or gain to a prior measurement, this is basic gravimetry.

The gravimetric technique is used … read more



Equilibrium Relative Humidity

March 11th, 2019

All posts, Damp / Rising Damp / Damp Proofing /

Today I revisited a property to take some equilibrium relative humidity readings in a hygrobox which I installed last week. The property is a new build which had floor screeds laid late last year. The clients are installing expensive oak flooring throughout and wanted to check the floors were dry prior to laying. I undertake these tests often for many flooring contractors and floor retailers … read more

Over the past year or two I’ve recommended remote heating systems such as Nest or Hive to several clients most of whom are landlords suffering with mould / condensation problems in their let properties.

As most will know mould and condensation problems are not just caused by poor ventilation, they occur due to an imbalance between a number of factors such as: moisture production, ventilation, … read more

Chimneys & Salt Contamination

September 28th, 2018

All posts

Nice example of salt contamination on a chimney recently.

Have you ever noticed discoloured patches which often appear damp on the face of your chimney? If so, this could be caused by salt contamination.

Salt contamination within a chimney occurs due to the long term effects burning of fossil fuels (coal and wood etc) in an open fire. When fossil fuels are burnt, contaminates are … read more



The truth about moisture meters (protimiter)

All posts

So, you want to know the truth about moisture meters?……………………………. They don’t work, they don’t actually measure moisture, they’re designed for wood, they’re a waste of time, you can make them go red by putting your finger over them! Yes, during my 20 years in the industry and 14 years as a professional surveyor I’ve heard all the claims, even the suggestion that “rising damp … read more

industry perception study

Although I dislike the thought, there is the perception that our industry is full of con artists; surveyors running around sticking inaccurate moisture meters in walls of buildings diagnosing rising damp in every property with the only appropriate solution being the inevitable retro-fit damp proof course and expensive re-plastering. It is an image which has tainted the industry for the past thirty years. Like many … read more
