We've had a great experience with the Edinburgh branch of Richardson Starling. They came and installed damp proof course and membrane to 4 of 7 rooms in our flat, and just gave outstanding service. There was more work to do than the survey had anticipated, and more electrics and radiators to come off walls, but their team were able to find members with the necessary skills to immediately solve any issues that arose. John the project manager ensured a smooth procession of tradespeople , so the job was completed within 2 working weeks. I was most grateful at their dust management tactics - working in masks with the doors closed and gaps masking taped over, covering everything in dust sheets and adhesive plastic carpet protector and sweeping up after every day's work. It was still a hard 2 weeks in our wee flat with a baby and cats, but it could have been very much worse. And we've a 30 year guarantee and a much improved home report to show for it. Thank you Richardson Starling, we'll come back for a third time in our next place.
