Conversions - General- 21 Jul 2024
STAY CLEAR!! Tommy responded to an initial job of removing a load bearing wall however we had to wait for building warrant to come through. In the meantime I had another major job which he agreed to complete at a cash price. Tommy and team have been on my property for 5 weeks and he now refuses to finish the job he started. He has been paid £9000 IN CASH and left me with unfinished electrical works, holes in ceilings, unfinished plastering in attic, hallway and ceilings. Photos have been taken I will be seeing legal advice. This man will take large sums of money upfront and will continue to move goal posts with cost, adding more and more onto original quote. My house is in a state that I now need to rectify at my own added expense. All I have I have to show for £9000 is 2 new velux windows and half finished attic that I cannot access as he refuses to install the stairs until I pay him even more money. Daylight robbery, he's obviously pulled this stunt with others. Be warned!

I cannot recommend Derek and his team of workmen enough. From quote to completion he has been excellent. Communication was amazing, any time night or day if we had questions he’d respond quickly and professionally, nothing was ever a trouble. Derek is very calm and chill but super efficient. He had a team of plumbers, plasterers, electricians, stone mason who all were all booked in in a timely manner to complete our new kitchen and garage conversion! Every trades person was super helpful and trustworthy which meant the job went so smoothly with minimal stress or inconvenience! We’re delighted with the work and would highly recommend DKL joinery 👍🏻

Conversions - General- 9 May 2026
WARNING — Stay far away from ROSS MCCALLUM Avoid Ross McCallum at all costs. This has been one of the worst experiences I’ve ever had dealing with a tradesman. After taking money for the job, Ross failed to complete the work, abandoned the project, and then completely stopped communicating. Calls were ignored, messages were left unanswered, and I was left dealing with the mess(I had to spend a fortune fixing his shambolic work.), delays, stress, and extra financial costs caused by his actions. What was promised was never delivered. Instead of professionalism, honesty, or accountability, I was met with silence the moment problems arose. No customer should have to chase someone they’ve paid just to get basic communication or unfinished work resolved. If you value your time, money, peace of mind, and property, I would strongly recommend looking elsewhere. My experience was extremely disappointing and I would never use or recommend his services again.
