This company was a nightmare to deal with. I have never experienced such amateur and inefficient work. They spent more time getting “ materials “ than actually doing the job. The bathroom renovation should have taken 2 days. Admittedly there were a few unforeseen problems. But basically just taking out and refitting sink and toilet. Their workmen were awful. They took over twice the time they should have. Also they never finished. The bath is still leaking. The sealant finish is amateur

In total 4 ridge tiles were broken, old tiles kept to show us the fault. New tiles in place and look very good. Extra work requested on the conservatory to fix leaks, still waiting to see if this has worked, but feel confident. A very good job done in the required time.
