Great job nice and clean even though there was an underestimate on the materials they stayed I ordered the rest and the job was finished. I then contacted them expecting a return of differnece on the materials that I laid out for on the day to complete the job this was 3 tonnes of Sharpe sand and 26 bags of cement which is quite an underestimate even though the floor did run out by 40mm over 2 square meter the materials delivered would not have finished the job regardless. they did not return any phone calls or emails for a few days when I was contacted I got told it was my measurement so its my fault and they weren't willing to compensate the extra cost so with that in mind the job ran well over £2,000. So my advice would be pay 50% then 50% on completion there a bit bad at estimating a job size and then its all firing paperwork in your face over the phone and not taking any responsibility for any of it. Or have a site visit which again they don't visit every job so that can be a cost of £200-£300 pounds which I was not offered but was told it was in the paperwork after the whole debarcle. one more thing if they can't finish a job on the day they will charge again for the following day so you could possibly get charged twice. so cover yourself pay a deposit and make sure you get all the information regarding costs Again the guys that did the job were amazing and incredibly helpful
