Very poor customer service and quality of work. A date was made to lay the floor screed and the materials were delivered the day before, all fine. The night before they were due Dyan WhatsApp'd me to say the clutch on the van had gone and they were trying to get a hire van. Another WhatsApp later saying they were not going to make it, it would have to be the following day (Friday) which i do not normally work, so had to make a special journey from Guildford to Poole especially to meet the screeders. I met the screeder and his labourer on site and they knew nothing about the breakdown!! I showed them around the floor to be screeded which had underfloor heating laid in four different circuits. All of the circuits had been filled with water and were pressured to 3 bar. Whilst looking around the floor the Eastern European guy said 'you've got a leak'. There was water spraying from a hole in one of the pipes. It transpired that the labourer had laid a plank of wood from the garden onto the floor- the plank of wood had a screw protruding out which had made the hole. I raced around Poole to find a roll of underfloor heating pipe long enough to replace the circuit. Eventually i found a roll long enough for the circuit and returned to site to remove the damaged pipe and re lay the new. Unfortunately this circuit could not be tested. In future conversation from Dyan he asked why i had replaced the pipe and not carried out a repair! I was aware that the original floor ran out of level but i was going to rectify this by the means of latex screed. The Datum point was given to the screeder but he has not kept to this and has run his new screed 20mm out of level from the front of the house to the back. Your brief email back to me mentioned the blockwork. No conversation was ever had regarding this and i am not sure what this has to do with a Datum point. I now have a small lip where the Bifold doors are to be installed. Furthermore i have great concerns over the integrity of the screed at the low end. Not sure now how much coverage of screed there is over the underfloor heating pipes. Some parts of the screed have started to dust up. When mentioned to Dyan he said it should have been covered with protective sheets. NO, the reason it has dusted is because the screed was too dry. I was there when the screeded told the laboured this! There was also some inconsistency with the mix. You could clearly see different colours of screed when it was first laid. I have requested a site meeting to discuss matters but this has been ignored. I foolishly paid 100% upfront so now have no leverage against them.
