10 Outstanding Full House Renovation
Posted 02 September
Extremely happy with the full house renovation carried out. Dealt with Luke who was extremely helpful throughout the whole process keeping me updated with what was going on. Works were carried out to a top standard and finished earlier than expected which is always a bonus. Would highly recommend if you're looking for someone who is reliable and actually delivers. Thank you LLOCK Building for making this an easy and enjoyable process considering the big changes that were made.Verified reviewerJob location: CM2110 Loft Conversion Review

Luke delivered a brilliant loft conversion, completing the project with remarkable speed and efficiency. His clear communication kept me informed at every step, eliminating any surprises. The craftsmanship was of great quality and perfectly transforming my space as planned. His honesty about pricing and timescales was refreshing and built complete trust. I’d recommend Luke for any future projects.Verified reviewerJob location: E1510 Brilliant!!
