Tibi Construction transformed our home, and the standout areas were the open-plan living space, en-suite renovation, and extensive plastering work. The quality of the plastering throughout the house was exceptional, with perfectly smooth walls and ceilings that have completely modernised the property. The open-plan living area was a major project, and the team handled everything professionally, creating a fantastic space that has become the heart of our home. Their attention to detail and workmanship were outstanding from start to finish. They also completely stripped out and rebuilt our en-suite, installing a new top-fed shower, toilet, sink, and full tiling. The finish is superb and looks far more expensive than the cost of the project. What impressed me most was their honesty and transparency. Material costs were always clearly explained, there were no hidden charges, and communication was excellent throughout. The team were reliable, hardworking and overall outstanding

We would definitely recommend Ben Gardner. He did a really good job putting up a new partition wall between two bedrooms. We cannot fault his professional work ethics - the quote was done very quickly and he did everything he said that he would. He was very polite and we would use his services again without doubt.

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 Bristol extension builder’s ability to deliver a result that meets your expectations.
