All cleaned up in the end and would recommend." > — Customer (5.0, via Which? Trusted Traders) > "The work that was carried out was replacing a flat roof. Philip spoke to my other trader who was in at the moment to make sure everything fit perfectly. Great value for money. Philip was always on hand to ask anything." > — Customer (5.0, via Which? Trusted Traders) > "My approx. 5m x 6m kitchen extension was completed with a fibre glass warm roofing system. The roof was boarded, vapour barrier fitted, insulation applied, top board fitted, fibre glass system applied. The roof was a flat roof with a large glassed lantern which had been installed by others. The survey was carried out by a helpful considerate surveyor who listened to my requirements he also gave his knowledge. I received my quotation in a good time, the quote was clear and a fair price. The install was carried out at the agreed date by a team of professional roofers who were courteous and hard working. The finished job is of a good standard and the up stand around the lantern was applied with skill as no residue is present on the glass. The finished job looks great." > — Steve at Portsmouth (5.0, via Which?
