How To Monitor Cracks
Tell-Tales are instruments used to monitor cracks in walls. These can be structural cracks, sometimes as a result of water escaping or leaking drains. The tell-tale is drilled and glued either side of the crack in the wall. If the crack in the wall has expanded or contracted in any way the tell-tale will illustrate the amount of movement on the graph stencilled on the tell-tale itself. The tell-tales are then monitored for a period of time. It is advisable to have an experienced engineer supervise this so that over time they could report the results to the insurance company in the event of the cracks expanding.

What Our Customers Say

Dan saved us over €5000 + more!
Dan inspected 2 houses for us, we were ready to buy. However, in both cases, he found issues with the pipework. Underground leaks we would never have discovered until it was too late and damage had been done to the foundations and structure of the house. He saved us over €5000 immediately and a lot more in the long run! I would recommend a drain test for everybody buying a house, it is critical information. Dan did a fantastic job explaining exactly what the issues were, his reports were easy to understand & ready the very next day! 5 STAR SERVICE.
