Stonemasonry- 2 Dec 2020
Fire damaged stonework above an electricity meter box and around a kitchen window. An awkward job but DSR were able to rise to the challenge. They turned up when they said they would so the job could interface with the window installers. They were also confident and competent enough to work in the vicinity of the meter box without the need to require disconnection which maintained our electricity supply. The quality of the finished stonework was very good and the lads were pleasant on site. All round good job and very satisfied, would easily recommend.
