Overall we are extremely pleased with our new loft conversion. Both Daniel and Steve were highly efficient workers, always on time, committed to the job and very friendly. The whole process from start to finish felt very smooth. Accessibility and communication were never an issue either. Acknowledging these guys are on a tight schedule we still felt some of the finishing work could be improved, especially on our project, an annoying floor creak which presumably could have been remedied by the chipboard being nailed/screwed down more firmly. Nonetheless, Daniel did return on several occasions following

Very Good value for money.
Richard was personable and gave us a fair quote for rear dormer loft conversion. Daniel and Steve delivered with the building work to a good standard. They were tidy, happy to accommodate any changes to our plans, liaised with our neighbours and consulted us on the specifics of the loft conversion. I felt comfortable giving Daniel and Steve keys to my family home. Thank you to Daniel and the team.

Apex recently completed converting the loft of our 1930s semi to a lovely en-suite bedroom and I can thoroughly recommend them. Richard guided us through the whole process and the project was delivered exactly as promised - on time and in budget. All work has been carried out to a really high standard and we are so grateful to Steve, Dan and the rest of the team for their skill and professionalism.

Back in 2010, Richard and his crew, converted our loft to a fantastic living space. We realised very quickly that Richard is the master of his trade - the whole process from beginning to the end was easy. We ended up with a first grade loft and nearly 9 years we are still very happy with our loft. Can't recommend Apex enough.
