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.
