Flat crack repair cost in Guwahati — what affects price

Hairline plaster crack vs structural column crack — very different costs. Here's what drives price in Guwahati flats.

Not every crack costs the same. A stair-step crack in partition plaster might be ₹5,000–15,000 to repair properly. A crack through a column or beam in Seismic Zone V can run into lakhs if CFRP wrapping, injection, and NDT are needed. Price drivers: crack width and length, whether steel is exposed or corroding, number of cracks, floor access (scaffolding for high-rise), and whether the crack is active (still widening) or dormant. NDT — rebound hammer, UPV, cover meter — adds ₹15,000–40,000 depending on building size but prevents guessing. Many Guwahati resale buyers in Beltola and Zoo Road use this before purchase. Epoxy injection for dry structural cracks: typically ₹800–2,500 per running metre depending on depth and access. PU injection for leaking cracks: similar range but may need multiple passes. We don't give accurate quotes without seeing the crack in person. Photos help for triage, not pricing. Free inspection first — we'll tell you honestly if it's cosmetic, monitor-only, or urgent. Waiting until monsoon water reaches steel inside the column often doubles repair cost. Book inspection early if the crack is in a column, beam, or load-bearing wall.
