Very impressed with this company, punctual, worked tirelessly and kept the place very clean. Wore plastic 'over shoes', not sure if this was just because I had a light cream carpet or whether this was done as a matter of course, neverthless it is the first tradesman I have had that has done it. Came back a few days later to check the system and do some other work that was quoted for whilst doing the original job! Would definitely recommend.
