Plastering- 29 Aug 2025
I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.

Extensions- 28 Jul 2017
Tony and his team recently completed a large ground floor extension. The guys were polite and courteous, on time every day, worked hard through the day and kept a clean and tidy site. Tony was very good at anticipating issues before they arose, making useful suggestions and giving us time to plan. We had a previous bad experience with a cowboy builder and Tony was especially sympathetic and understanding. Tony and his team were always transparent and upfront and very easy to work with. Tony was recommended by neighbours that he had worked for and we would also highly recommend him.

Kevin was very professional, polite and reliable. He worked efficiently and was tidy. He was also very helpful and explained things clearly to me.

Landscaping- 2 Oct 2020
From the moment Alex arrived - on time - to quote for the work he was full of energy for the job, interested in what needed doing and had some great ideas. I received a clear, detailed quote and Alex was happy to talk everything through. Alex, Christian and team are skilled workers, polite and tidy. The work was completed to a high standard, on time, and has totally transformed my fenced area and garden - beyond what I had imagined. My neighbours on both sides were so impressed they have also hired We Fix. I would have no hesitation in recommending Alex and his team. A great professional outfit. Thank you We Fix!

We did not go ahead with this job as we did not purchase the property, however, Craig and his team phoned me and explained to me over the phone what is needed and provided me an estimate over the phone which is what I was looking for. This helped me and put in to context what I was dealing with. Thanks very much.

Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!
