Mastering Small Bathroom Budgets: Uncovering Hidden Costs in Demolition, Masonry, and Plumbing

Scenario 1 (The Old Way): A quote read, “Demolition and Disposal: $15,000.” Ms. Wang thought it was reasonable and signed. After work began, the contractor said, “The raised floor needs to be broken up; this is special demolition, an extra $5,000.” “Too much trash, requiring an extra truckload, another $3,000.” She was caught off guard by the escalating costs.

Is it just removing tiles, or also old plaster and the raised floor layer? What about ‘waterproofing’? How high does it go? How many coats? What materials are used? When the quote doesn’t specify, a contractor can perform to the ‘minimum standard,’ and any work exceeding that becomes grounds for additional charges.
