What Our Clients Say

Real reviews from our satisfied customers.

"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

"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

"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

"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.

"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."
