Damp Proofing- 23 Mar 2025
My issue was cured by tanking part of the wall and floor of my annex, to stop water ingress from my neighbour's garden. It was reasonably predictable that my outbuilding would act as a retaining wall against the raised soil of his garden; but I could not see the higher ground or the suspect drainage that was causing the issue. I would have needed to hire a surveyor; but Daniel served the same function, expertly using drone footage to establish the neighbour's drainage and uncapped, deconstructed chimney stack as the dual cause. I appreciate Daniel's commitment to accuracy in his reporting and value the strategic thinking that he brought to the tanking project, maintaining it at the highest standard. Thank you for being potentially prepared, through your drone footage, to step up to assist with the letting agent's collaborative efforts to bring pressure to bear on the owner/landlord. Your professionalism, and that of your expert team, reflect well on your company.

Extensions- 17 Oct 2020
Overall an excellent build. Although this was a straight forward build, foundations, concrete floor, single skin blockwork walls, pitched roof with corrugated bitumen sheeting roof, key to the build was the flatness and levelness of the concrete floor and neatness of the blockwork and pointing on the inside as it was not to be rendered on the inside. My initial concerns of using a Contractor I had no previous direct experience were gradually alleviated as the build progressed. James, Greg and their team were good workers and skilled at their trade, particularly Dan and Harvey. My real concerns over the ability to delivery the quality floor were dispelled when seeing the team at work, Greg takes the lead for groundworks and blockwork and did an excellent job. The quality of the blockwork has attracted many positive comments from passing neighbours, as has the finished roof, soffits, facias and bargeboards. The use of AGR for the demolition and groundworks and GMC for the high spec. concrete can be highly recommended. The use of 'Ozzy' (Paul Evans) for the small fibreglass flat roof can also be recommended. Early on in the build I had some concerns about material shortages on site meaning that precious hours of good weather were being lost but a sharing of these concerns resolved the issue. JH were open to consider changes and extras on the build for which I was grateful. Communications with the client is key and there were a few times when I had to chase for info. Very happy.
