My name is Paul and I've been in the building trade since leaving school 40 years ago. I started out as a steel fixer, then went to college to gain a City & Guilds Level 3 in carpentry & joinery. Over the last 40 years I have become proficient in all aspects of the building trade. I specialise in extensions, loft conversions and refurbishments. I have had refurbishments featured in Home & Gardens Magazine and The Daily Telegraph. I live in Sidcup, but am willing to travel. All my work has been on personal recommendation. I pride myself on providing a quality service at a fair price and support the client from the beginning to the end of the job.

Restoration & Refurbishment- 1 Feb 2026
The WORST experience I have ever had with a tradesman. I would strongly advise others to stay clear. There was no schedule of works at any stage. Adrian failed to plan, failed to communicate agreed works, & did not even tell his own workforce what they were meant to be doing. There was no evidence of professional oversight or management, resulting in chaos & extreme delays. I was repeatedly misled. He stated that Building Control had been contacted & paid for; but when I contacted them directly they confirmed no application or payment had been made. He damaged my property & instructions were ignored. He was rude, aggressive & shouted at me in my own home, which I found intimidating as a woman. Neighbours also complained about his behaviour. Despite multiple extensions, the job was left unfinished with little communication. He caused significant stress & a serious loss of time & money. The matter is now being resolved through the courts. I would NOT recommend him under any circumstances
