I was also concerned when I saw this thread about problems with rendering, as I had paid a deposit to Protective Rendering Systems for thermal insulation and rendering of my property. So I did my research, checked out the validity of the guarantee with the insurance company, checked the quality marks, and then discussed my concerns with Harrison Springfield. I found his responses to be credible, and asked him to continue with the job, (as I was initially tempted to withdraw the contract). The work has just been completed, and the rendering surface is superb. The lads, Don and Jamie have done an excellent job. There were a couple of minor snags that needed rectifying, so I contacted Harrison as soon as these became apparent, (on a Sunday) and plans were put in place immediately to sort them out, and these have now been completed. I find the best approach is to do your research, be straight, and tell people what your concerns are, that way issues can be resolved before they turn into problems. I have never had to "chase" Harrison or his colleagues to talk to them, in fact they have had more trouble getting hold of me at times, to advise me of progress and starting dates. I am happy that I chose Protective Rendering Systems,
