Plastering- 2 Dec 2024
He’s a hard worker, very polite and did the job very quickly over two days. The only problem being that one of the walls came off. He did come back with no arguments and fixed the job.

Extensions- 16 Oct 2019
Not trust worthy, does not follow the contract, he pulled out in middle of my work in house three times. Never finished on time. Promised to come back and finish The fence and the toilet never come back despite numerous phone calls. I have leaking toilets in the wall big pigments of dampness on the wall paper on the wall adjacent to toilet. Promise to do the roof tiles then he said I cannot do it. Fitted the kitchen units wrong and did not connect the sink overflow pipe to the macerate ( leaking water under sink. Flooring tiles not even still have prominent corners . Front driveway is cracked as he promised to dig and put concrete but last minute changed his mind and put only cement and new slaps. Water pipe outside house is leaking . The stairs carpet and the wooden stairs not painted rightly and the carpet is not fixed right it is out. I paid him all the money left only 150 pounds but never come back to paint fence, summer house finishing and loft ladder. Brought materials and his workers and brought bills never saw some of it. Taken some materials in his van and never discussed this issue. Work meant 6 weeks and now 8 months and still not finished. Do not hire him he and his workers are not up to standards. Will love one from builder. Com come and see the unfinished and damaged in my house.

Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.
