I recently had the pleasure of working with MDG Building, and I can’t recommend them highly enough. From the start, they were professional, and clearly very knowledgeable. They not only installed a shower screen, vanity and toilet but also took the time to help with an unrelated problem I was having installing my fridge—something they absolutely didn’t have to do, but stepped in to assist anyway. What really stood out was their commitment to doing the job right and there willingness to go the extra step!

Alex and his coworker from C&P General Construction Ltd did an exceptional job repairing and repainting my front door, 7 door frames and most of the skirting boards around my flat. They both are very friendly and are very good at being neat and paying close attention to detail. Alex offered a reasonable price and made sure they both took their time so it was done to a very high standard and to my satisfaction. I felt even more confident when Alex shared his professional advice throughout. Thank you Alex! ????

I had got few quotes for fence installation and chose to go with different contractor instead of JD. They did a terrible job. Posts started leaning and rocking significantly after couple of weeks of the installation. I asked them to come back and fix but they did not. Then I contacted JD and requested him to come and repair the fence. Joshua was quick to react and made himself available next day for the job. He reinstalled almost all of the posts with proper depth and alignment. Highly recommended fencer.

Marcel worked efficiently to deliver a high quality finish to our bathroom renovation. He communicated what he was doing at each stage of the renovation and was helpful in sourcing the materials. He worked long hours and always cleared up after himself. Marcel is friendly, honest and hardworking. The quote was very reasonable in comparison to other quotes we received, our first quote was honoured despite the job being more complex than initially anticipated. We will be using Marcel again for other jobs.

We used Kingz for clearance of a very overgrown garden and new fencing. They did exactly what they said they would do in their quote. They worked hard, left the garden tidy, and took away all the waste. They were very pleasant and Emma, in particular, gave good advice regarding ongoing after care of the garden. We were very happy with the results and would definitely recommend this family team!
