A few months a go we appointed a building company that is FMB and Trust Mark registered and provided IWA warranty to carry out a refurbishment of our kitchen - 1. Remove old suspended floor and replace with concrete flooring with underfloor heating and tiled (we provided the porcelain tiles that costed £1800 in total). 2, Decorate new kitchen 3. Provide plumbing for new appliances 4. Hide all plumbing pipe work behind walls and floors 5. Install 2 new radiators 6. Remove and install new skirting 7. Re-wire extractor fan 8. Add a new network cable under the floor to the router which is located in the front of the house. 9. Replace kitchen door and windows From the above list the issues are as follows - 1. Concrete was not left to cure for the amount of days required as per guidelines (few cracks appeared on the screed prior to tiling), Underfloor heating was not commissioned as per guidelines, Decoupling Membrane for tiling was initially left out but when advised was in the contract, was re-added, Tiles have been laid above the original floor level and therefore forming a step into the kitchen (they have added a threshold to create a small slope to avoid an actual step but as we have a wheelchair user in the house hold, a threshold is not ideal!) and lastly the tiles they have laid have multiple small chips due to kicking off levelling clips and the floor is at a small gradient as they did not use a self levelling compound and therefore some of our kitchen units are at a noticeable tilt. *The issues with the floor being un-level was mentioned to them when the screed was dry and prior to laying the tiles and yet still the issue was not rectified! 2. A few areas they have missed out to decorate... 3. Forgotten to provide plumbing for our new fridge freezer! 4. Only installed one radiator instead of the 2 * when issues with floor were mentioned they left odd jobs out and did not return 5. Skirting not installed - Refund offered and accepted but not paid as of yet. 6. Did not re-wire extractor due to issues with RSJ in the way - refund accepted but not paid as of yet 7. Network cable was only half compelte therefore making it redundant. 8. Initially quote for both windows and door was provided as apart of the overall quote however at the time of work, PM mentioned only quoted for 2*windows and 1 door instead of 4*windows and 1*door. The building firm have now created us multiple inconveniences as we are not sure how good the flooring is (any underlying issues) and with the other jobs not done, we are going to have to find new tradesman... The owner (who was the PM as well) walked off the job when the issues were brought to his attention. He initially said he would resolve them and apologised but when knowing the flooring issue is potentially massive (may need to be lifted) it looks like he took the easy route out. How should I go about tackling this issue with the company, how will I know what is an acceptable amount of refund + compensation and should I get arbitration through FMB involved? I have spoken to Trading standards and their advise indicate that I may be able to ask for upto 100% of the contract due to the fact that they have broken the terms by not performing jobs and 'not performing some with due care and skill even after a repeat performance'. We have our new kitchen being installed in 2 weeks and I sent the building company an email on 7 days ago stating the areas they have performed badly and not carried out jobs. The surveyor has gotten back to have stated they will respond by mid next week. Any suggestions would be greatly appreciated.
