He was very good at the job and finished on time etc. The one thing I found slightly annoying was the urgency to finish the job and get the money, ie insisting that he paints the fence even though it was forecast to almost certainly rain that day and receiving multiple calls from his wife etc to our pressure. Overall though I am pleased with the end result and will use him again if given a chance

Rob and his team did a really high quality job and we are very pleased with the end result (and I am the son of a builder, so my expectations were high to start with).. The finish is excellent on the render and the quality is constant through what was a fairly large rendering job on my detached house.

ZELJKO BURGER (known as Charlie) did an amazing job of replacing a roof on our orangery from start to finish. We were quoted an extremely competitive price (Charlies quote was almost half of that quoted by a well-known competitor) and once we had accepted his quote, we were amazed at how quickly work began. It was carried out with a minimum of fuss and disruption. Charlie has transformed what was once a cold, unusable room into a functioning extension to out home. I definitely recommend him.

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.

STAY well away from this company. Quoted to fit stair carpet and stair rods. Arrived late and Ryan started to cut the stair rods. Ryan stayed for 3 hours then just walked out with no warning and never came back. I then found out that he cut 8 of the stair rods incorrectly. I advised him of this and he said he would replace. After not responding to my texts I can assume he is not replacing them which has now left me £88.00 out of pocket to replace. Be warned .

I had initially been given a reasonable quote for the work required. After the work had started, they offered to build a new wetroom and install a new megaflow tank. Halfway through the job, he said the cost had increased and wanted to charge me 50% more. I was furious as I had my budget set already. I disagreed and had several arguments, where Anthony Baafi was being extremely unreasonable. In the end I had to pay a bit more, as I just wanted to get the work finished. I do not recommend them to anyone!

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.
