Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.
