It was perhaps a small "bitty" job with a few complications (my fault) along the way but it was completed in time with good communication and expertise. It was done exactly as I requested at a good price so I have no hesitation in recommending.

Dave did a teriffic job clearing up my very overgrown garden and accomplished in just a few hours a job I had been ignoring for months. He was very prompt to reply to my posting and appeared in the garden just a couple of days later. He did such a good job he's coming back to build us a bike shed and sort out the flowerbeds. Great job, thank you Dave!

Hired this tradesperson all went well for a short time - his team walked out on him and he could not get the appropriate trades to complete various stages of the build - after complaining about the constant delays he stated he would not come back and is now in breech of his contract- due to his inability to obtain the relevant tradespeople his plumbing “expertise” has now caused a leak underneath our newly fitted kitchen floor! Which we are having to pay to repair! Disgraceful!

The team first gave a competative quote for the work. A good start! They turned up on time, and then paid attention to my requirements before starting the job. They worked hard and efficiently together to get the job done. 7:30 AM to 18:00 without a break. The result was to professional standards. Would I recommend them? Yes, very much so!

Shortly after finishing our renovation the floor began to lift, after a 2-year battle and almost court they admitted it was a fitting fault. Not ideal for a 12k job. Now our sink has fallen in, turns out he has used the world's smallest bit of wood and some sealant to fix it to the underside of our granite worktops rather than correctly fitting it using the fixings on the actual sink. Add to this, gaps between drawers and misaligned cupboards and you get the idea.
