Bathroom Fitting- 7 Oct 2025
I recently hired Delfi Construction to remove and replace 3 sinks and 4 toilets in my property, and I couldn’t be happier with the results. From start to finish, their team was punctual, professional, and highly skilled. They handled the removal of the old fixtures with care and precision, ensuring everything was done cleanly and efficiently. The installation of the new sinks and toilets was flawless, with attention to detail that really stood out. Communication was clear throughout the entire process, and the team was respectful of my space, leaving the work areas spotless once the job was completed.

I was not onsite for the majority of the renovation, so i was heavily reliant on Daniel to project manage the refurbishment. Daniel is realibe, trustworthy, punctual and honrable.

The job was done immediately and took just half of the day. Was very good communication between the date we contacted Johny and he gave us very good advice. He had patience to all our questions and gave us a lot of indication and options comparing with other builders. In the end, he did more jobs for me because he has a big company, so we did with him the plumbing system as well. Definitely recommend this person and his company because they did the jobs properly and very quick, no need to wait 3 weeks or even worse 1-2 months to book them.

Bush builders did a great job replacing a ceiling in our house along with adding extra joists and insulating. Their professionalism was evident from our initial meeting which was further backed up with the competitive quote they provided and the extra care they took to make sure we had the right type of sheep's wool insulation for the job. It only took a few days to do the whole thing and they left the room as clean as possible after such a messy job.
