Service · 32-point structural audit

Structural Integrity

We physically inspect the load path of your future home — foundation, columns, beams, and slab — using rebound hammers, alignment lasers, and crack-depth gauges to catch defects that paint and putty are hiding.

47%

of new Indian builds show micro-cracks under 0.3 mm within the first 18 months of possession

₹4.2L

average repair bill once structural defects are caught after possession (CREDAI 2024 estimate)

specific load, alignment, and crack checkpoints per visit, mapped to IS-456 norms

How the inspector analyses your home

1
Rebound hammer testSchmidt N-type hammer fires at 12 concrete points per floor. Readings below 25 R indicate sub-grade M20 concrete and trigger a flag for the developer.
2
Plumb & alignment scanSelf-levelling laser checks wall verticality. Anything over 6 mm deviation per metre means structural skew and is non-negotiable in our snagging report.
3
Crack-depth mappingUltrasonic pulse velocity reveals if a hairline crack is cosmetic or has penetrated to the rebar. Cracks deeper than 2 mm are photographed, measured, and timestamped.
4
Beam & slab deflectionDial gauges measure live load deflection on cantilever balconies — anything exceeding L/250 is reported as a non-conforming beam.

Thermal & Moisture Imaging

Water is the silent killer of Indian apartments. We sweep every ceiling, wall, and wet area with a 320×240 thermal camera and pinless moisture meters to find seepage paths and pipe leaks before they bloom into ₹2-lakh problems.

18%

moisture content is the threshold above which we declare a wall actively leaking

320×240

thermal pixel resolution — sharp enough to spot a pipe leak inside a 9-inch wall

How the inspector analyses your home

1
Full-house IR sweepThermal imager captures every ceiling, external wall, and bathroom partition. Cold spots indicate active seepage; hot spots flag faulty electrical concealments.
2
Pinless moisture mappingProtimeter Surveymaster scans non-destructively up to 19 mm deep. Readings above 18% are flagged; above 28% triggers a slab-leak investigation.
3
Dew-point analysisWe log indoor humidity and surface temperature to predict where condensation will recur — useful for catching deceptive "freshly painted" patches.
4
Plumbing pressure test15-minute pressure-hold test on inlet lines. Any drop > 0.2 bar is documented for the developer to repair.

Electrical & Fire Safety

Faulty wiring is India's #1 cause of urban residential fires. We test every circuit's insulation, verify the earth pit's resistance, and confirm the panel's load capacity matches your appliance plan — so the fan doesn't sing when the geyser is on.

35%

of urban residential fires in India trace back to faulty wiring or short circuits (NCRB 2023)

≤ 5 Ω

maximum earth pit resistance permitted by IS-3043. We flag anything above 3 Ω as a hazard.

circuit-level tests per visit — including RCD trip-time and insulation resistance at 500 V DC

How the inspector analyses your home

1
Insulation resistance test500 V DC megger applied to every circuit. Readings below 1 MΩ indicate compromised wire sheathing and force a re-pull on that circuit.
2
Earth pit verificationFall-of-potential method on the building's earth pit. Anything above 5 Ω is non-compliant; we recommend re-salting and re-charcoaling.
3
RCD / RCCB trip-timeLoop impedance meter triggers a 30 mA fault. Trip must occur within 40 ms — slower means the breaker won't save someone in a leakage event.
4
Load & sanctioned-load matchSum of installed loads checked against the meter's sanctioned capacity. Mismatches lead to summer trips and warranty disputes.
5
Fire-safety walkthroughWe verify smoke detector placement, sprinkler head clearance, and fire-extinguisher servicing date in common areas.

Service · Smart, solar, EV-ready audit

Smart & Green Home Audit

We audit your home for the next decade — not the last one. Solar capacity, EV charger feasibility, Wi-Fi coverage, and water harvesting potential are scored and reported with concrete numbers, so you can plan investments in advance.

3–5 kW

average rooftop solar capacity supported by an Indian 2BHK with south-facing terrace access

32 A

minimum dedicated line required for a 7.4 kW Level-2 EV home charger

-65 dBm

Wi-Fi signal threshold below which we declare a "dead zone" needing a mesh node

How the inspector analyses your home

1
Solar irradiance surveyPyranometer logs noon irradiance across the usable roof. We hand you a kW-peak estimate and the simple-payback period at your DISCOM's net-metering rate.
2
EV-readiness checkWe inspect the parking-bay conduit run, sub-meter availability, and main panel headroom to confirm a 32 A charger can be installed without re-wiring.
3
Network coverage mapWi-Fi heatmap generated room-by-room. Dead zones below -65 dBm are mapped, and we recommend mesh-node placements optimised against wall thickness.
4
Water & rainwater auditInlet flow rate, storage tank sizing, and rainwater harvesting feasibility checked against your locality's monsoon yield.

Service · Legal & RERA review

Contract Review

Most sale agreements in India are 60+ pages of fine print that quietly disadvantage the buyer — possession clauses, indemnity carve-outs, common-area redefinitions. Our panel lawyers comb every line and flag everything you'd otherwise sign blind.

22%

of RERA filings in FY 2024-25 had non-compliant possession or penalty clauses

₹1.4L

median legal cost saved per buyer when defective clauses are negotiated pre-signature

standard red-flag clauses we check against the RERA Model Form sale agreement

How the legal team analyses your contract

1
Title-chain verificationWe trace ownership back at least 30 years via sub-registrar records. Any break in the chain is flagged with the specific encumbrance certificate number.
2
RERA cross-checkProject ID validated on the state RERA portal; promoter history, complaint count, and pending litigations are pulled into your report.
3
Clause-by-clause annotationPossession date, penalty for delay, force-majeure carve-outs, indemnity caps, and assignment rights all annotated in plain English next to each clause.
4
Negotiation packYou receive a redlined version of the agreement with recommended edits — ready to share with the builder's legal team.
