Real reviews from our satisfied customers.
"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
"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
"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 had a complete refurbishment of my bathroom by the Buildaway team recently. I received an excellent service from the outset with a very high standard of the completed work. Cormac was very responsive to my wish for a traditional period bathroom and helped me to source the suite, the tiles, the paneling and flooring. The team are respectful to the home generally. I am very pleased with the finished bathroom."
Philomena Mulcahy
"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."
