George Bell came to work on some damp related issues in my flat in feb. since having completed the works the problems which first occurred have turned worse and George has been unwilling to get back in contact with me, despite chasing him for 5 months which only reaffirms that the job was poorly undertaken. The company main reception also seems to be a virtual reception so you can never speak with anyone helpful

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!

Use at your own risk. Did good job on garden wall even had comments from passersby say how good it was. Phil even got jobs from local builder based on what he did when they saw it. But as for the rest of the work laying the patio in the garden he quoted £1200 for I expected a first class job considering the actual concrete only cost £305. But he subcontracted it out to someone who did a worse job then I could have done myself. I have been in contact with the person who did it but hasn't sorted.

Poor quality work, had to get it re-done. Did not remove bamboo root as asked, hid it inside a raised bed along with lots of rubbish. Poor brickwork on raised bed - didn't even notice had changed from stretcher bond until I pointed out the mess. Patio & path had wobbly slabs (turns out they had laid it without a sub base) & when I asked them to re-do they didn't turn up to finish the job. Hassled for money as they went along, unfortunately I paid most of it. Had to use the remainder to get it done right.
