William and Paul worked tirelessly and with great expertise putting our 200 year old windows back together. The skill involved was superb, as was their committment to causing minimal disruption to the household. The finished job is beautiful. Can’t recommend highly enough. Mr K

We have a Victorian terraced house with many original features, including the sash windows, and were keen to restore rather than replace. William was thoroughly professional, patient and tidy, and we were delighted with the finished result. We would recommend his skills and craftsmanship to anyone looking for a high quality sash window restoration project. Mrs T

We are writing to thank you for the well crafted job you carried out on our property in Queen Street. When other companie’s would only recommend that we replaced the windows, you used your expertise to refurbish them to their former glory and at half the cost of the quoted replacement windows. We would not hesitate to recommend your firm to anyone in need of replacement or repairs to sash windows. If we are ever mad enough to take on another wreck to renovate we will give you a call. Also thanks for leaving everywhere so clean & tidy. Mr and Mrs W

William Robertson carried out repairs to all of the sash windows in our house in East Grove Rd. William was thorough, tidy, and reliable and the repairs were at a reasonable price. Overall we are very pleased with the quality of his work, and paricularily with the care he took in selecting the right kind of timber for the sash windows. We would be very happy to recommend William to anyone else considering similar work- thanks for a great job! Mr and Mrs K

William Robertson repaired the sash windows in my house in 2009, from first to last Will was professional, efficient, honest and very pleasant to work with. His standard of work is of the highest calibre and seeing the skill and care with which the windows were repaired is amazing. The finished windows open easily, are draught proofed and look beautiful. I would highly recommend anyone who is thinking of having their windows repaired to give Will a call: its a pleasure to recommend such a good craftsman. Miss S

William Robertson of Sash Window Repair Ltd replaced a wooden sash window when the original sash window was rotten beyond repair in our Victorian student rental property in Exeter. He supplied, glazed and painted the new sash and ensured it opened freely. The service was timely and professional and the workmanship was of a high standard. I certainly recommend William Robertson for such work on sash windows. Mr M

William repaired 6 of our sash windows putting in new weights, cords and beads in the most professional manner. We were very pleased with the finished result and impressed with how cleanly and diligently he worked. I have no hesitation in recommending his work to others.

William has carried out some extensive sash and casement window restoration for a recent renovation project of mine. His repairs are very thorough and precise, and I have every faith that the restored windows will now last another 100 years. His estimate was very detailed, and he has made me aware at every stage of exactly what work has been done. He completed the work within budget and on time and is a pleasure to have around. Mr D

Really pleased with the quality of Will’s work. Kept us informed of progress and costs throughout. Friendly, professional and reliable. Good follow-up service. A true craftsman – a rare find. Mr F

We had sash windows through our Victorian property which we were keen to keep rather than replace with UPVC. We had looked everywhere for a restorer and had a good selection of quotes for the work. William Robertson was professional, personable, reliable and informed about his craft. He delivered the work to a high standard in the agreed timeframe. His quote was spot on and he kept us informed of any potential add on costs. He was reliable, always returned calls and really cared about the finish and standard of the work. We have windows that are the envy of the rest of the street thanks to Will! Would not hesitate to recommend him. Mrs P
