Justin came to quote for the job and provided an accurate quote with an estimated time for completion and start date for the job which was great. The job was to knock down an external wall and rebuild it, plaster and finish. Justin and his team completed the job to an excellent standard, were complete reliable throughout and really clear with communication and expectation of both costs and time. Whilst the work was completed they were really fantastic at keeping the home as clean and dust free as possible (which on this sort of job was incredibly hard), clearing up at the end of each day and leaving the space a manageable place in the evenings. A great job highly recommend
