HDB design: spotting hidden costs before you sign (pitfalls)

Unexpected costs can arise from hacking existing structures, electrical rewiring, plumbing modifications, and addressing structural issues discovered during renovation. Always factor in a buffer for unforeseen expenses.

Be clear about the scope of flooring work. Check if the quote includes screeding, hacking of existing tiles, and disposal fees. Factor in the cost of leveling uneven surfaces.

Ensure the quotation specifies the number of power points, light points, and switches included. Clarify the cost of additional points and any potential upgrading of the electrical load.

Confirm the type of materials used (e.g., plywood, particleboard, laminate finishes) and their associated costs. Check for extra charges for internal fittings, drawers, and customized designs.

Inquire about the number of paint coats included, the type of paint used, and whether the quote covers surface preparation, patching, and primer application. Some contractors charge extra for painting ceilings or feature walls.

Clarify if the quotation includes the cost of replacing old pipes, relocating water points, and installing new sanitary fixtures. Check for hidden charges related to waterproofing and drainage issues.
