"LXM Building Services recently completed fire compartmentation works to all 9 roof spaces at St Mary’s Mansions, and their performance was outstanding from start to finish. The project involved complex and sensitive work in residential blocks, but the LXM team handled it with professionalism, care, and great attention to detail. Their knowledge of fire safety regulations and compartmentation standards was clear from the outset, giving us confidence that the work would be fully compliant and executed to the highest standard. Great job!"

"Extensive work was carried out on the flat, with a full gut and strip-out needed. I am extremely happy with the quality of work and the speed of carrying out the work; it was finished exactly on time. Ingli was great to work with throughout the whole project, and I couldn’t recommend him and the team any higher."

"Completed a full refurbishment at my property in Cheshunt; extremely happy with the quality, service and workmanship. Any issues or queries I had were handled quickly and to my exact satisfaction, so I was very impressed with the communication throughout the job."

"We renovated our family home in SW1 towards the end of last year. Ingli and his team at LXM did a fantastic job throughout. A few challenges, but the consistent communication did help to keep everything tidy and within the deadlines."

"LXM sent a lovely man, who was easy to communicate with, and his team; they did an amazing job."

"LXM are a family-orientated team who are the most professional and efficient workers we have worked with."

"Impeccable work. Minimum snagging, and when there was, it was remedied immediately."

"Fantastic service from LXM Building Services — professional, reliable, and excellent quality work. Highly recommend."
