"Great communication . The fitters were polite and curtious and worked well as a team . Would recommend this company and with a long guarantee coming with the works piece of mind aswell . Many thanks"
"We were most impressed by the clear communication, punctuality, courtesy and high standard of workmanship shown by the whole team."
"GJ Smith Roofing were very competent and professional and the attention to detail was excellent, taking the time to consider the final aesthetics by aligning what was previously a 2 roof job. However, some rotten wood was left in situ so I am hoping this will not cause issues going forward and delays due to weather are completely unavoidable and understandable but a phone call AFTER the agreed start date on 2 occasions was irksome."
"I want to make it clear that I had not previously met Gary the owner of GJ Smith so apart from the reviews online I had nothing to go on. His office however is a 2 minute drive from my house and on that basis it made sense to ask him to quote. I received 3 prices for the roof and GJ Smith were the lowest by far. Because of this I invited Gary back to revisit his initial quote and as a result of a more in depth conversation about the work the price did increase slightly but it remained significantly lower than his competitors. I was very clear with Gary about the expected standard of work and conduct of his workers from the outset and his team comprising Ben, Floyd and Geordie looked after me impeccably. The work was carried out to a ridiculously high standard and I remain highly delighted with the result. GJ Smith Roofing are professional, very competitive and a pleasure to deal with. As a contractor they inspire total confidence and Gary is a real gentleman (a rare find IMHO)."
"Very helpful from start to finish. Came at short notice during wet weather, to re-roof a flat roof over a ground floor extension, happy to recommend."
