We carry out lots of hard cement pointing removal, or sometimes just disgustingly bad re-pointing. Most of our lime pointing is carried out using traditional lime putty.
This is the type of pointing that you don’t want carried out. This just shows how somebody can actually think this is ok, this is probably the worst pointing I have seen on stone.
Again another disgusting pointing job, I can’t actually believe somebody thought this was any good!!!
Hard cement pointing trapping in moisture, causing accelerated timber decay and Deathwatch beetle infestation to a property in Somerset.
Another hard cement pointing trapping in moisture causing the bearing end of this purlin to decay to a property in Wiltshire.
This particular job was on a property in Warminster, Wiltshire, the initial enquiry was of a damp problem on the ground and first floor. The survey consisted of a thermal imaging survey along with a damp survey to BRE Digest 245, this property had only 12 months before had damp proofing works carried out, unfortunately for the retired couple this works had failed and the contractor wouldn’t come back to fix the problem.
Thermal imaging and data collected from the mortar samples and hygroscopic salt analysis proved that there was 2 issues, one of the main problems was the penetrating dampness and rising damp. The consequence of the penetrating damp had caused a bearing end timber to decay and also a very small localised dry rot out break to the timber lintel. Complete Preservation prepared a specification for the remedial works, which consisted of the removal of the plastic paint to the gable wall, removal of the hard mendip dust cement pointing, this was re-pointed with a lime putty which will allow evaporation of any dampness by the sun and the wind. A timber repair was carried out to the bearing end timber and the lintel was replaced as necessary.

You wouldn’t recognise the house now, the lime pointing and the lime render look stunning!
The below Wiltshire property had suffered with a small amount of penetrating dampness from a gutter leak, and also around the porch area. Some of the original lime pointing was worn and some repairs had been previously carried out with hard cement pointing. If you notice above the windows there are no lintels, the bricks above these were loose although there was a timber lintel supporting the internal skin of the wall. We were instructed to remove all the old original lime pointing and hard cement pointing, replace with a traditional lime putty mortar. We also were asked to carry out sympathetic structural repairs, we created a masonry beam using 6mm stainless steel helical wire along with helical grout ties. The porch roof was also stripped, and re-felt and battened, the chimney was also capped and we fitted vents to help combat any dampness problems.
This is a close up showing the hard cement pointing and also showing there is no lintel above the window.
The below picture shows it finished, it looks beautiful!
