“We would not hesitate to recommend Nitor Ventilation”

We recently completed the fire damper programme with Nitor Ventilation and have been extremely pleased with both the quality of the work and the professionalism of the team throughout. The project was delivered efficiently, with clear communication at every stage, and a strong understanding of compliance requirements and operational sensitivities within a live estate environment.

In particular, the support provided by Jordan and Kit has been excellent. From initial planning through to completion and importantly in the post-completion phase their responsiveness, technical knowledge, and willingness to assist have given us real confidence in the integrity of the works. Any queries have been handled promptly and thoroughly, and their continued support after handover has been greatly appreciated.
