Extensions- 4 Jul 2019
Unfortunately for us, it was not made clear that both Skifter and Mo have full time day jobs that they fit this work around. Additionally for us, the constant debates about what is and is not included in the quote got tiresome.

Joinery & Cabinet Making- 9 Dec 2024
Very impressed by Eugene's work. I hired him to build a bin shed for my front garden. He took the time to understand what I wanted and work out how he could combine the look I was after with a stable structure. I am so pleased with my new shed. Eugene is trustworthy and reliable and I will hire him for other work in the future

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.

Windows & Doors (uPVC & Metal)- 29 Jan 2024
John did a fantastic job of replacing a large sash window in our kitchen. He was easy to work with, and was very clean and tidy with the job. On top of that the price was very fair, particularly for the calibre of work completed. Would recommend!!
