Very average in term of service and workmanship. You gotta know and be on top of everything in order to ensure things won't go wrong and if it does, as expected, they came out with all sorts of excuses just so to avoid re-do or correcting their mistakes! And because of that, the whole process delayed and dragged on to more than 2 months!!
Quality of workmanship is Very Average, definitely not gonna recommend them to anyone who's looking for a worries-free and quality bathroom renovation. Very disappointing!
