Extensions- 12 May 2026
Maninder recently built an outhouse for us and we were extremely impressed with both the quality of work and his honesty throughout the project. Everything was completed exactly as promised, with no hidden costs or unexpected extras. The workmanship was excellent, and even other tradespeople have commented on the high standard of the build. What also stood out was that Maninder always recommended the right approach, even when it meant extra work for his team. Highly recommended.
