I would like to recommend John from JKA Damp Proofing and Sika tanking (07713 187226) as he has just finished a long job in the basement of my Victorian house on Crystal Palace Road I had a very bad case of water getting into the vault under my front stairs, as well as a damp problem in a number of spots at the back of the house He removed plasterwork back to the brick and removed the front steps, which threw up some small structural problems which John dealt with quickly and professionally. Tanking the vault area and replacing the front steps once the sika concrete was in place His concrete and plaster work is excellent and done with real enthusiasm. Although it's impossible to avoid mess when removing old plaster, John works with care and keeps disruption to a minimum, with plenty of dust sheeting and floor protection. Once the job was done, there was a full clean up As with any building work, final pricing often goes beyond original cost estimates, but John made sure we discussed and agreed any additional work that needed doing and kept me informed on costs all along the way Overall, a really good job done to a very high standard. Thoroughly recommended if you can find a spot in his busy diary!
