“I needed a new front door to be compliant with current fire regulations. Roy and his team got the job as an affordable price was quoted. They arrived on time and got the door changed with minimum disruption to myself. Cleaned up as they worked and were very polite and efficient. I would highly recommend Roy and his team, very impressive.”

Google Review by Glenn
“We recently onboarded RTJ to undertake a full refurb of our 1st floor offices and training facilities, this comprised of a full repaint of all corridors, offices and training rooms, new carpet tiles in the offices and classrooms and the installation of a new kitchenette. The team were professional throughout and very accommodating to our requests or sudden changes to the original plan, some of which were at very short notice. I would certainly recommend RTJ and will be using them again for any future projects.”
