It was a time challenge for me to move to newly purchased house as my rental agreement was due. I got Saby from personal reference. All home colour, wiring, removing old big boiler, water tank and rerouting of all pipe work. Roof repair , new two en suites construction, whole IKEA kitchen. He delivered as per our expectation and design in 8 weeks. No time waste and all material he arranged. I am very happy the way he professionally handled the work and delivered on time. I would recommend him. Make sure your design is ready and perfect. Discuss with him before start and avoid changes for best results.
