Review by Darren

"We recently used C Shambi Builders for a loft conversion and extension, having previously used them for other work, and once again we couldn’t be happier with the result. From start to finish, the team were professional, reliable and a pleasure to deal with. Communication was excellent throughout, and any questions or changes were dealt with quickly and helpfully. The quality of the workmanship and attention to detail were exceptional, and it was clear the team genuinely cared about getting everything right. Having major work done to your home can be daunting, but we felt completely confident in them throughout the process. They were respectful of our home, worked efficiently and delivered a finished space that has completely transformed the property. The fact that we chose to use them again says it all. We would have no hesitation in recommending C Shambi Builders to family and friends. Fantastic service and an excellent result!"

David Owen - Image 1 "We’re absolutely delighted with our renovation. Chris and his team did a really great job, we feel like we’re living in a new house! We booked Chris having read reviews and checked him out online. Everything we read has been accurate and we want to add to his 5* collection as we are very happy to recommend him. Apart from the quality of work from his team - which is excellent, what most impressed us was his communication. Chris is a builder that replies to every message/ voicemail. He checks in either in person or over the phone every day so you know which tradesman is in and what the plan is for the day. He organises his team really well and the guys are great and highly skilled. The carpenter built our media wall from scratch using mocked up AI pictures that we provided, he also fitted our staircase from pictures we showed him. Chris has excellent contacts across the industry so put us in touch with them for additional purchases including the quartz worktop."
