Even the best wooden flooring fails if installed incorrectly. In India, poor installation — wrong subfloor prep, missing vapour barrier, no expansion gaps — accounts for 80% of early floor failures. This guide tells you exactly what should happen, what it should cost, and what to watch for.
What Happens on Installation Day (And What Should Happen)
Step 1: Subfloor Inspection & Preparation
This is where most Indian installations go wrong. The subfloor must be:
- Level: Maximum 3mm variation per 1.8 metres. Humps and dips cause the flooring to move, squeak, and fail at joints
- Dry: Moisture content of concrete subfloor must be below 3% (UK standard) or below 5% (acceptable Indian standard). Test with a moisture meter — not by feel
- Clean: Free of dust, adhesive residue, and debris
- Anti-termite treated: Apply approved anti-termite chemical to the subfloor before any flooring goes down
If any installer skips this step — stop the job. Subfloor prep costs ₹20–₹60/sqft and is non-negotiable.
Step 2: Acclimatisation
Wooden flooring (particularly engineered wood) must acclimatise in the installation room for 48–72 hours before fitting. This allows the boards to adjust to the room's temperature and humidity. Boxes should be opened and stacked in the room — not left sealed. Skipping acclimatisation in humid Indian conditions causes gaps in winter and buckling in monsoon.
Step 3: Vapour Barrier
In India, a vapour barrier (polyethylene sheet, minimum 150 microns) must be laid over the concrete subfloor before underlay and flooring. This is non-negotiable for ground floor and any installation in humid climates. For engineered wood, use a combination vapour barrier + underlay product.
Step 4: Underlay
Underlay serves three purposes: acoustic insulation (reduces impact noise), comfort underfoot, and moisture buffering. In India, use:
- 3–5mm foam + vapour barrier combination for laminate and SPC
- 3mm cork or rubber underlay for engineered wood — better acoustic performance
- Never reuse old underlay — replace entirely for every new flooring installation
Step 5: Installation (Click-Lock Method)
For click-lock laminate, SPC, and engineered wood:
- Start from the straightest wall, work across the room
- Stagger joints by minimum 300mm (ideally 450mm+) — never align joints across adjacent rows
- Leave 10–12mm expansion gap at ALL walls, columns, and vertical surfaces. Indian temperatures cause greater expansion than European specifications. This gap is covered by skirting boards.
- Use tapping blocks — never hit boards directly with a hammer
- Cut last row to fit — minimum plank width of 50mm for stability
Step 6: Skirting and Finishing
- Install skirting boards to cover all expansion gaps
- Fix skirting to the wall — NEVER to the floor (the floor must float freely)
- Fit threshold strips at doorways and room transitions
- Seal around bath/shower edges if using SPC in wet areas
Installation Cost in India (2026)
| Item | Cost Range |
|---|---|
| Basic labour (straight lay) | ₹40–₹70/sqft |
| Labour (herringbone/chevron pattern) | ₹80–₹140/sqft |
| Underlay + vapour barrier | ₹15–₹40/sqft |
| Subfloor levelling (if needed) | ₹20–₹60/sqft |
| Anti-termite treatment | ₹8–₹20/sqft |
| Skirting installation | ₹80–₹200/running metre |
| Old floor removal | ₹15–₹35/sqft |
7 Mistakes That Ruin Indian Wooden Floors
- No vapour barrier on ground floor — moisture from concrete destroys the floor from below within 1–2 monsoons
- Skipping subfloor levelling — uneven subfloor causes joint separation, squeaking, and premature failure
- Tight expansion gaps — European 8mm gaps are insufficient for Indian temperature swings; use 10–12mm
- No acclimatisation period — boards installed too soon after delivery buckle or gap seasonally
- Cheap underlay — thin foam underlay compresses within months; invest in quality
- Skirting nailed to floor — prevents floor movement and causes cracking; always fix skirting to wall only
- No anti-termite treatment — in termite-prone zones (most of India), skipping this step risks total floor loss within 3–5 years
How Long Does Installation Take?
- 1 BHK (400–600 sqft): 1–2 days
- 2 BHK (700–1000 sqft): 2–3 days
- 3 BHK (1200–1600 sqft): 3–5 days
- Add 1–2 days for subfloor levelling if needed
- Add 2–3 days acclimatisation before the install day
