What Our Clients Say

Real reviews from our satisfied customers.

"A great transformation of my bathroom into something modern and sleek. Cormac was professional to work with from the start and was very helpful in taking my ideas and sourcing products to fit the space and look aesthetically pleasing. I felt confident in working with the company as I could ask questions and I was also pleased to get suggestions and ideas. Cormac and Mo worked hard to deal with any issues that arose and they were friendly, helpful and I felt that I was valued as a customer. They were reliable and were always on time to arrive. Having a bathroom refurbished is a big decision and it was important for me to trust Cormac. I read reviews and met him in person to discuss the project and I am happy to give a positive recommendation to this company."

Vera Jajechnyk

"I wanted a bathroom refurbishment done and after meeting with several tradesmen decided to go with Buildaway Construction Ltd. From my first contact with Cormac, I was in good hands. His team turned my vision into reality, communicating with me every step of the way and offered helpful suggestions which turned my bathroom into an oasis. I could not be happier and would highly recommend their services. Thank you to the team of Buildaway Construction Ltd."

Jackie Brown

"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

"We’ve had a genuinely fantastic experience with Buildaway. Cormac was ultra responsive and excellent at communicating with us throughout our project. The quality of the work was excellent - so much so, that we extended our project by adding a range of other building renovations to our original ask, each completed with care and precision. Cormac and his team clearly take a lot of pride in the service they offer - from a really helpful initial visit and quotation, to the high quality work delivered - they even thoroughly cleaned all our rooms and touched up any marks. We would highly recommend them to anyone considering getting work done. Friendly, reliable and also competitive. Thanks for all your help."

Kiran Collier

"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

"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. 👍"
