What Our Clients Say

Real reviews from our satisfied customers.

"Buildaway recently finished a two week job completely renovating my bathroom and part renovation of the downstairs toilet. Cormac and his team did an incredible job. The quality of the work, their high standards, and their professionalism, along with effective and proactive communication made a refreshing change from the builders I have used in the past. Even when we changed our minds and ideas during the job Cormac’s patience and support emphasised that he wanted to make sure that the finished product was exactly what we wanted. From ordering products, to suggestions and ideas Cormac was helpful and a pleasure to work with. I would without question use Buildaway again for other work and would have no hesitation in recommending them to friends and family."

Michael Marks

"It was a pleasure working with the Buildaway team to reimagine a tired old bathroom into the most attractive room in the house in just two weeks. Cormac's enthusiasm, communication, and project management are top-notch - he went above and beyond on more than one occasion. Greg's attention to detail and dedication elevated both the experience and the result - he certainly knows his way around a tile. In addition to the bathroom refit, Cormac replaced all the plastic switches, sockets and pull-cords in the house with brushed brass. Highly recommended and will certainly work with the Buildaway team again."

Kane Dempsey

"It was an absolute pleasure working with Cormac and the Buildaway team. Greg is an absolute star. Cormac’s communication and advice was excellent, and the organisation and sourcing of additional materials was brilliant. A truly great team, I would thoroughly recommend Buildaway if you are after a stress free and top quality renovation."

Sim Lewis

"Cormac & his team were brilliant throughout our bathroom renovation project. From scoping to completion, Cormac was always very responsive, answering any questions we had on product selection and helped us source the products to get the best price. His team worked extremely hard and a big shoutout to Greg for his attention to detail! We couldn’t be happier with the results and would highly recommend Buildaway for any building project in the future."

Georgina Ehmcke

"I posted a bathroom job on a Bark App and within ten minutes I got a notification that I had about 5 responses. I spoke to Cormac of Buildaway first, explained my plans a bit and he asked where I was and when I told him, he said I am not far, I will come and view the place. In half an hour he was at the door and from his introduction in my mind I said I think he will do the job. He came in, I showed him and detailed my proposal, he listened and then checked, measured and said to me it is doable and will get back to me with a quotation detailing the scope of work. Indeed he delivered as promised, we discussed thoroughly in detail, checking everything, gave me ideas as well as listening to me. We agreed on a plan and he delivered. Any issues or worries I may have had, he was always available to explain and reassured me. Cormac is very good with communication, listening, advising, a hard worker and an excellent team/project leader. He has been transparent and I would not fault him in his deliverance of what he promised to do. I am extremely impressed, happy and proud of what he and his team of Archie, Ben and Danny delivered. They all went beyond and far, I am very grateful for what they have done for me. I would 100% recommend Buildaway for any building, renovation etc - an excellent team with a good rapport, team spirit and working harmoniously together. Thank you Team Buildaway. Thank you Cormac, you are a star. 👍"

Betty Lwanga

"Cormac and his team were excellent from start to finish. Communication was clear and consistent both before and throughout the project, which made the whole process feel well managed. Cormac was really responsive on any questions I had and always contactable. Cormac provided really helpful advice on products and design, and clearly understood the look I was aiming for. That made a big difference and really helped me make decisions. The quality of the finish is excellent, which was one of my top priorities. The team took real care to get everything right, and Mo in particular has a fantastic eye for detail. They were also very professional day to day - always tidy, and cleaned up really thoroughly when taking away all rubbish at the end. They stuck to the agreed timelines, and pricing was transparent throughout, with clear communication on any issues as they arose. Overall, I’m really pleased with the result and felt I could trust them throughout. I wouldn’t hesitate to recommend them."
