Real reviews from our satisfied customers.
"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
"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
"Exceptional Bathroom Refurbishment and More! I was recommended Buildaway by a colleague as I was impressed by the work they had done for my colleague. From the moment I contacted Cormac, I knew I was in good hands. He was incredibly friendly and accommodating right from the start. The very next day, he was at my property, taking measurements and discussing design options. What really impressed me was Cormac's honesty. He was upfront about what would and wouldn't work with my space, which was quite tight. I was a bit indecisive, changing my mind several times, but Cormac remained patient and helped me design and choose materials for my dream bathroom. Communication was exceptional throughout the entire project. I didn't have to worry about a thing, as Cormac and his team effectively project-managed everything, which was a huge relief since I was mostly away during the project. They were on-time every day and completed the job in the agreed-upon two weeks. The team was respectful of my space and left everything clean after completing the project. I can't thank them enough! I highly recommend Cormac and the Buildaway team for bathroom refurbishments and all other building work. They are more than competent and reliable; you'll be getting the best of the best. Cormac even provided advice and recommendations for other projects in my house. Don't hesitate to book Buildaway for your bathroom refurbs or other building projects - you won't regret it!"
Nana A.
"We recently used Buildaway for a full bathroom renovation at our home in Orpington, along with plastering, redecoration of both bedrooms and new spotlights installed in the bedrooms. From start to finish the experience was smooth and well organised. Cormac was easy to deal with, communication was clear and everything ran to the agreed timelines. The team turned up when they said they would and kept the house tidy each day, which made a big difference while we were living in the property during the works. The quality of the finish is excellent. The bathroom looks fantastic and the bedrooms feel completely refreshed. We wouldn’t hesitate to recommend Cormac and the Buildaway team."
Helen Sivyer
"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."
Sean Kelleher
"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."
