Fire door repair gaps and fire seals
Specialist had to visit properly twice as they alleged they have fixed issue but showed still with issues following Fire risk inspection. On the second visit, they left me one 1/2 working lock after sealing the other lock without realising. Contacted engineer to come and finish the job several times, and I have never received reply. Had to book different specialist to finish what they started!!Job location: UB7RMohamed EResponse from Apex-Assure Ltd
Very disappointed with this feedback, work was completed, and you asked us to return to look at something you weren't 100% happy with, which of course we will always do if needed, but to request us at gone 7pm with absolutely no wiggle room on this is unreasonable
