A word from our clients

  • “Bart and his crew did an exceptional job. The weather was terrible and things did not always go to plan, but despite this GB Construction worked to resolve and delivered a very high standard job, on budget and with minimal disruption to us as we were living in the house at the time. The whole crew were always polite and tidy and the associated trade companies and staff were also excellent.”

  • “We were recommended GB Construction from a carpenter and have never looked back. Bart and the team have transformed our (what was a 3 bed one bathroom) house by doing an L shaped loft conversion and side return down stairs, now providing 5 bedrooms and 2 bathrooms. Bart and the team have been professional, honest and trustworthy throughout the build period. Whilst we changed our plans slightly/ added additional work, this did not create issues or delay matters. The finish is to a very high standard. Very pleased indeed.”

  • “Bart and his team completely gutted and refitted a new bathroom on time and on budget. All trades were very efficient and hard working with a high level of finish. We now have a beautiful bathroom and thank everyone involved. We will definitely be using Bart and his team again.”
