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!

Aquarius Bathrooms

Reviewed by Zac on 8/2/2011

AVOID AT ALL COSTS My first mistake was to ignore an earlier scathing review. I only required tiling, all tanking was completed in advance, so decided to overlook the questionable plumbing/electrical feedback in a previous review. My experiences and the behaviour described appear to be entirely consistent though. Alex completed the tiling of the wet room to a poor level – he was unable to deliver a level tiled surface in a number of areas despite a fully Marmoxed room to work with. The toilet could not be fitted to the frame as the tiling was so inaccurate there was an enormous amount of rocking. The most serious problem was his inability to lay a level floor, critical in a wet room, and we have a number of areas of pooling. Having been given a perfectly level tile friendly Hardibacker surface to start with this is inexcusable. He agreed to return and rectify these faults, came back, smashed out several tiles on the walls and the floor then disappeared never to be seen again. At the time he claimed he needed to go and pick up some tile adhesive which seemed reasonable. A few minutes after he left I noticed he had taken his tile cutter which of course he would have needed on his return. This set alarm bells ringing. I looked at the wet room more carefully and knew that was going to be the last I would see of him. When removing the tiles from the floor he had damaged the under-floor heating cables. He made a clumsy effort to disguise the fact with some tape before his exit. After a couple of hours I received a text message claiming that he had been involved in an accident and that he would be in touch. After several days of ignored calls and messages I sent an email and received a reply claiming that his phone had been stolen and this was the reason his unresponsiveness. He promised to come the following Friday to finish the job. Needless to say he failed to show up, ignored calls, text messages and emails throughout the day. I knew he was in possession of his phone and proved the fact by getting my partner to call from a number he would not recognise. She was promised a call back by his partner – of course it never came.

The quote was provided quickly and the work carried out on the arranged day. After giving time for the floor to harden I found it was very uneven and sloped in two directions. I have had to correct it by applying a floor screed. Also some rubbish was left in the rear access passage behind the houses. It was agreed that it would pick it up but it wasn’t so I had to remove it so it didn’t obstruct the alley way for my neighbours.

They were not unqualified. They met every regulation in the book. You first said the wires needed to be in conduit, but when I had this checked, you then accepted that this was not the case. You said the 'regulation had changed' but conduit was never a legal requirement, just something done for practicality. The electricity was working fine for 3 days before you came and started working. This is nothing personal just bad trademanship, which I have a moral duty to highlight to others.
