Highlights
"This is the second house Justin has done significant works on for us after a renovation in our previous home a few years back. This ended up being a bigger job than anticipated due to issues which were uncovered during the project (old house) which Justin communicated clearly and was proactive in finding solutions. Very happy with the end product and team always tidied up at the end of each day. Justin and team were also very flexible working around our family needs as well when needed. Would happily hire Justin again."
"Thanks Justin and the team at JCM! The floor got completely flooded the other week and all the leaks were fixed, along with a new tiled floor, with some nice new stone looking tiles. They were quick to respond and did a great job, even with the few last minute changes! The floor really does look good now. Much appreciated :)"
"Justin and his team carried out a structural alteration to the back of our house to allow for new doors to be fitted. They did a great job, completing what was asked and letting us know about an unexpected problem they found which would result in more work being needed. The work looks great and was completed pretty much on schedule. Thank you!"

Smart checks
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.
