Horrendous. Poor work & owes me a fortune! Avoid at all costs!Verified reviewerJob location: WA1210 Bathroom & ceiling fixing , tiling and sink/toilet reinstatement
Posted 31 August 2024
Marek did an excellent and conscientious job. Communication was regular, informative and helpful. He did a great diagnostic of some underlying issues (the age old problem of poor previous work undiscovered!) and was solution focused to remedy. The reinstatement work and tiling work done was first rate. I can fully recommend Marek who I found to be fair, honest professional, highly conscientious with the skills to deliver excellent services.Verified reviewerJob location: SE2110 Bedroom Renovation
Posted 23 May 2024
We are very happy with the work carried out by Marek on our son's new bedroom. Marek is diligent, with an eye for detail and carries out the tasks to a very high standard. He also explains the work to be carried out at each stage so there are no surprises. He undertook a number of different tasks including relocating and installing a new radiator, hiding the previously exposed 1950s pipework, wall and ceiling repairs, joinery and laying a new floor.Verified reviewerJob location: SE2310 Creating a large bathroom w storage from a small closet and small cloak room
Posted 20 May 2024
Marek is a very talented builder. He worked hard to demolish an awkward sized closet and awkward bathroom, creating one large bathroom with a nice storage. Mark took the time to discuss the storage with me, he was very patient and very helpful with his advice. We are family of five and now have a small mudroom type place to store all of our coats and shoes. Marek was neat, tidy, and pleasant to have in the house for so long. I think his work was top qualityVerified reviewerJob location: SW179.75 Repairing extention roof, fitting new shower in bathroom
