Making Chota Castle’s problems history
Victorian cottage for damp and timber infestation in the picturesque and historic village of Chew Magna, Bristol. The problem was so acute that the company decided to use two specialist treatments in order to ensure the problem was completely eradicated.
Facing a two pronged attack
The cottage which is known as Chota Castle, is a privately owned home which is renowned throughout regional gardening circles for its exquisite gardens. However, the house itself, was fighting a losing battle with the elements and a common woodworm. As a result, the internal decorations and plasterwork was severely breaking down.
Surveyor Mark Benbow said: “Even on visual inspection it was immediately apparent that the property was suffering from excessive dampness. This was confirmed on detailed investigation and was evident in the chimney-breast and the walls which appeared to be due to the absence of an effective damp proof course.”
Peter Cox experts installed a chemical damp proof course incorporating the Peter Cox DryWall Diffusion Process. In addition to the damp proof course and to control rising dampness in the walls, the team removed the existing plaster and treated the wall with its DryWall Coating system. On the chimney breast area, the company applied two coats of DryWall Porestop Waterproof Slurry onto exposed masonry and then treated that area with same DryWall Coating System.
Mark said: “The problem was particularly severe in the solid floors on the right hand side of the cottage and so we recommended a specialist work treatments which saw us installing a three coat Resin Damp Proof Membrane.”
In order to considerably reduce moisture vapour condensing on both the underside of plasterwork and the rear surfaces of skirting boards, and so extend their life span, it was important to form a vapour barrier up-stand raglet joint to the parquet flooring in some wall / floor joints. Where the original plaster extends below the floor slab, it was raked out, cleaned and the void filled to floor level. A vapour proof slurry coating was applied to the wall-floor intersection up to the damp proof course installation level.
“Once the damp proof course had been successfully installed we turned our attention to treating the wood worm infestation,” said Mark. “This, like 75% of infestations in the UK was caused by the common furniture beetle Anobium punctatum. This also had to be treated with a specialist insecticidal fluid.”
A decisive victory
This meant Peter Cox had to carry out insecticidal timber treatments to the main roof void, the rear additional roof void, all exposed and accessible timbers to the ground and first floors and the staircase. The process is quite challenging as it was important to ensure that while the affected timbers were treated, the unaffected areas were not damaged.
Peter Cox was on site at Chota Castle for several weeks but after all the treatments had been applied the family can be assured that the treatments carried out are guaranteed for years, leaving them much more time to tend their well-loved garden.
