Highlights

"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."

"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."
