Avoid these traders. They are amateurs and have caused me no end of pain with a small single storey front extension. I sacked them in the end as we just could tale anymore of their slap dash approach.

Extensions- 13 Jan 2023
David McGill from Dm Brickwork and his team built a Garage on the side of my house for me they have done a fantastic job exceeded my expectations. The guys are really nice friendly and professional. They helped my disabled wife move her car in and out of the drive as she couldn’t and even helped her in with the shopping. I will be asking them to come back to build a patio in the future and recommend them to anyone that needs building work done.

Completing our scope with Insight ProBuild from start to finish was one of the most least stressful projects we have ever completed. From start to finish, Anil was on hand generating creative ideas/suggestions, providing clear and achievable plans/schedules, and managing the scope to our agreed budget. Overall, Anil earned our trust through careful management of the Project, handling all the interfaces and taking the stress away from us, having a clear eye for detail and quality of his product, excellent communication through regular engagement with us and ultimately delivering a high-quality Project in the end. Even after completion, Anil was excellent by following up on any issues and ensuring we were still happy with the completed scope. Would recommend Insight ProBuild as Anil genuinely cares about his product and prioritising the relationship with his clients to ensure they are satisfied and happy.
