Direct Answer: Homeowners frequently face 20% to 35% unexpected cost overruns when hiring budget contractors who quote low initial rates. Common hidden costs include 18% GST excluded from proposals, unbilled loft framing, electrical switchboard shifting (₹800/point), and granite edge polishing.
The Danger of Low-Balling in Interior Quotes
Many homeowners choose an interior contractor because their quote was ₹1.5 Lakhs lower than competitors. However, halfway through the project, the contractor presents sudden “extra bills” for basic requirements that were deliberately left out of the initial quotation. At Home Tour Interior, our quotations are 100% all-inclusive—the price you see is the exact price you pay.

The 10 Hidden Interior Costs Decoded
- 18% GST Excluded: Many contractors quote ₹5,00,000 verbally and then add ₹90,000 as GST at the time of final invoicing. Always confirm if quotes are GST-inclusive.
- Loft Framing & False Walls: Quotations often mention wardrobe shutters but secretly exclude the internal carcass and wooden loft framing, costing an extra ₹35,000 per bedroom.
- Electrical Conduit Shifting & New Points: Moving a TV socket or adding warm LED strip wiring typically costs ₹600 to ₹1,200 per point, quickly adding ₹25,000+ across an apartment.
- Kitchen Chimney Core Cutting: Drilling a 6-inch circular hole through the builder’s reinforced RCC beam for chimney ducting costs ₹2,500 to ₹4,500.
- Countertop Edge Moulding & Sink Under-Mounting: While granite stone may be included, double-nosing edge polishing and under-counter sink cutouts often incur ₹12,000 in unlisted labor.
- Soft-Close Hardware Upgrades: Baseline quotes often include noisy manual hinges; upgrading to soft-close hydraulic fittings costs ₹500 to ₹800 extra per shutter.
- Service Lift & RWA Protection Fees: Floor masking with bubble wrap and elevator cladding often gets billed back to the client.
- Debris Clearing & Deep Cleaning: Clearing construction sawdust and chemical residue often adds ₹8,000 to ₹15,000 if not contractually specified.
- Bathroom Plumbing Alterations: Shifting bib taps to align with modular vanity units.
- Transportation & Unloading Tolls: Extra charges for lifting materials to 10th+ floors if freight elevators are restricted.
