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.

What experience do you have with similar extensions in Mill Hill?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Mill Hill extension builder’s ability to deliver a result that meets your expectations.
