"Very professional and hard working. High standard of workmanship. Excellent service."
"Pleasant, professional, good job. Couldn't have asked for a better service!"
"GJS have just transformed my old and tired looking conversatory into a modern dream. Before the room was too hot to use on hot days and too cold throughout the winter. The new roof has worked a treat and we are really happy with the end result. I had the pleasure of having Alex and Luke on the job. Both were extremely professional and did a great job. Being heavy pregnant and with a 4 year old, I was worried I would be inconvenienced throughout the work but this didn't happen. All the team were polite and updated me regularly on the job. They even worked over the weekend to get the job finished before time. I would definitely recommend GJS roofing and shall contact them again in the future. Thank you again GJS I can now relax knowing I'll have the perfect space for my growing family."
"Great communication and work carried out as planned. Would highly recommend. Thank you!"
