We recently bought a an older private 4+1 bedroom condo(abt 1,800 sf/169sm) and engaged a builder to carry out complete revamp of the kitchen, 2bathrooms, utility, maids room and maids bathroom. Having only just come across this website, I'm afraid I am being overcharged by the builder. His quotation lacks a lot of detail . Here it is: Protection to unit floor $400 Hack tiled wall/floor/cabinets of kitchen, 3 bathrooms and utility room ) Dismantle false ceiling in kitchen/bathrooms ) $7000 Dispose concealed water pipes in kitchen ) Apply water proofing to kitchen, utility and 3 bathrooms ) $13,000 Supply sand and cement to level floors and walls ) Supply and install plaster ceiling for kitchen and 3 bathrooms $2300 Supply and install 2 granite tops and vanity cabinets for the 2 bathrooms $4000 Supply and install new concealed water pipes for kitchen and 3 bathrooms $6500 Supply and install tempered glass sliding door and screens in kitchen and 2 bathroom $7500 Supply and install aluminium frame bi fold door at maids toilet and maids $900 Supply and install 2 wall mirrors for bathroom $400 Supply and install new refuse chute $500 Sand and vanish wooden flooring in 4 bedrooms $1000 Polish marble floor in living/dining and corridoor $1400 Paint whole aprtment $1900 Supply and install 3 Rheem waterheaters (6gall, 15gall, 20gallon) $1480 supply and install 2 pop up waste in 2 existing bathtubs $500 Supply labour to install new vanity sink inside master bathroom $250 GRAND TOTAL $49580 The above does not include cost of tiles and sanitary ware. This does not include us engaging a kitchen ID company to do the design and build kitchen cabinetry !! having just moved back from Australia, where the cost of doing a kitchen by itself is abt $50K- I guess we didnt do much research into the whole thing. The builder came recommended by our trusted real estate agent and before we engaged him, he took us to a couple of places that he was working on to let us see the quality of his work. The places were pretty high end (Orchard Boleuvard etc) and we were pretty impressed. We have just started the reno works 1 week ago- no deposit or downpayment have been made. So far, he has hacked all the areas and replaced the water pipes. I need advice on: 1. How much discount should we ask? Before we engaged him, we asked him for a discount and he had agreed he will give us one but did not specify the amount. He kept re iterating that because we are close friends of the real estate agent(whom im sure gives him a lot of work), he will "look after us". Is 10percent reasonable discount? When I mentioned this, he started ranting about getting another contractor etc etc Getting another contractor is not an option at this stage. We are already paying rent and enormous amts in the storage of our container from Austrlia and any delay means more money to us. Would really appreciate any advice on how to deal with this. So far, my relationship with him is good and I dont want him to sabotage me by lowering the quality of his works.Thanks!
