“I was very impressed with the recent fire damper testing. The whole process has been dealt with very professionally and thoroughly throughout. Paul and Aiden have been on site for 3 days now and have been an excellent example of how professional, responsible contractors should behave. They were polite and friendly, always professional. Signed in and out every time, requested information and assistance when needed but were otherwise self-sufficient. It was a pleasure to work with them.”

“I would like to pass on my thanks to your engineers, Neil Morley and Reece Victory for their superb service. They were very knowledgeable, professional and thorough, working methodically through the building. This was the first time that I have used RJ Urmson and based on this first visit I would be very happy to make future bookings for additional works.”

Colin Bott

“The contractors carried out a stellar week of work. They carried out their duties faultlessly. I didn’t get one single complaint from our staff and the volume of testing that they are got through was outstanding. It was a breath of fresh air working with such a proactive and competent company. We have had such shocking experiences with respect to fire damper testing in the past and I was beginning to lose faith, rest assured RJ Urmson have restored it. Thank you again for providing such a brilliant service.”
