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

"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

"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

"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

"We had an excellent experience working with Buildaway. Cormac was incredibly easy to work with, and gave helpful advice. The finished job was neat, professional and completed efficiently. We'd definitely recommend and would use them again!"

Roisin Lawrence

"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."
