Latest review:
Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

Gus and Frank were brilliant. Their attention to detail and care for our project was evident. There was already an issue with our floor which Gus and Frank rectified for us before doing the tiling. The final finish was immaculate. We liked their work so much that we also got them to fit our kitchen worktop. Good communication and clarity throughout the job. Would definitely recommend!

Bricklaying- 12 Nov 2016
Dear Brian I have tried to contact you on several occasions to complete the job. I really do not wish to leave negative reviews all over the Internet. Will you get in touch? Just ignoring the situation will not go away as I am now in receipt of your insurance documents and want to resolve amicably. I put you on notice to get in touch within 7 days. If I do not hear back I'm afraid I will have to start the legal processes as you give me no other option. I hope to hear from you within the allotted timeframe and do hope we can avoid litigation in this circumstance. Thank you. Dawn

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.
