I just did a complete gut kitchen renovation in Pacific Heights, San Francisco with this company. In the past I have renovated 11 bathrooms and kitchens and never had as wonderful a contractor as Long Vong. His integrity is unrivaled and he is always ahead of schedule solving any problem easily with beautiful work and craftmanship. Cannot speak highly enough of this company and have already recommended them to several friends. Whoever works with this company is truly fortunate and be prepared for them to exceed you expectations in every single way.
