Spencer has been nothing but professional from start to finish. Communication was very good and he kept me up to date with costs and timeframes. The work was carried out in about 2 hours and Spencer and his colleague left our house spotlessly clean when they were done. The broken window is now fixed and we’re very happy with the results; we would definitely recommend this company.Verified reviewerJob location: TN12 10 Overhaul composite front door
