Reliable and high standard builders
I’ve used Justin and the team for all of my major building work over the last few years, from kitchen and bathroom renovations, replastering and drainage replacement. They’re reliable and responsive and have done all of the work to the highest standard. I have recommended JCM many times to friends.Verified reviewerJob location: SO1510 Property Maintenance / Repair

Floor tiling and skirting, plumbing and flood damage prevention.
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 :)Verified reviewerJob location: SO52RDaniel B10 Builder

Removal of multiple internal walls, install of bifolds, and install of new kitchen
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.Verified reviewerJob location: SO16
