Highlights
"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."

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
