“We commissioned SG Woolley Ltd to add a single storey extension to our property and to carry out renovations. The work was completed in line with the pricing quotation and we were entirely happy with the quality of the work. Sean is clearly a very experienced builder and was always on Helmand to deal with any questions or concerns. The team working on our property were very capable and we were pleased that they took care to try and minimise disruption to our neighbours during the building work. I would recommend this building firm.”

“We contacted S G Wolley to take the old roof off our garage and renew with a flat felted roof, plus fill in the side which was open, and re route the gutter etc. the guys turned up (no air over teeth) just got on with the job in hand, very clean and tidy, absolutely brilliant job, no eye watering quote, top job, top team.”

“Having used S G Wolley on previous occasions, always being delighted with their work. Late 2033 I instructed them to build a new 2 storey extension. At the same time overhauling the entire roof. They have delivered on time, on budget and the finished building is superb. 100% recommend this excellent local builder.”
