Rossmark has been truly impressive. We have used them to make substantial modifications to our home, including addition of an upper floor, with the work lasting nearly six months. From the very first meeting it was evident that Matthew Earl was very professional and pleasurable to deal with, meticulous in evaluating the options and giving us very detailed information on the products he uses as part of his quote. Once work commenced we could see how well organised and thorough they were, kept us fully appraised of how things were progressing, and even rectified, at their own time and cost, several issues that were revealed in the existing house. In the end they finished work ahead of schedule, and delivered an excellent quality finish that I am very impressed with. I maintained a blog of week-by-week progress, and am happy for others to see it to get an idea of how things went. All-in-all, I have no hesitation in giving Rossmark the highest possible recommendation, and have every intention to use them again to do further work on our house.
