Most flooring damage we see at Avikar has nothing to do with the floor itself — it comes from cleaning it the wrong way. A wet mop left standing on laminate, an acidic tile cleaner dragged across SPC, or a solid wood floor scrubbed the way you would scrub a bathroom tile: each of these does more harm in a year than a decade of ordinary footfall. We have been fitting and living alongside floors in Kolkata homes since 1971, and the questions we get after installation are almost always about upkeep, not choice. Here is a straight, floor-type-by-floor-type answer, built around what actually happens to a floor in this city’s humidity and monsoon.

Why Kolkata’s climate makes floor care different

A care guide written for a drier city will quietly mislead you here. Kolkata runs high humidity for most of the year and then a genuinely wet monsoon from June to September, followed by a comparatively dry winter. That swing matters more to a floor than almost anything you do to it deliberately. Wood-based floors — solid, engineered and laminate — expand as they draw moisture from humid air and contract again once the fans and air-conditioning dry the room out. None of that is damage by itself. It becomes damage when standing water, harsh chemicals or the wrong cleaning routine are added on top of a floor that is already moving with the season.

The cleaning rule that applies to every floor type

Before the floor-specific advice, one rule sits above all of it: a damp mop, wrung out until it barely feels wet, beats a wet one every time. Pooled water is the single biggest cause of the floor problems we get called out for — not because floors cannot get wet, but because water that is allowed to sit finds its way into joints, edges and the sub-floor underneath, and that is where the real damage happens, wood-based or not. Sweep or vacuum first to lift grit, because grit dragged around under a mop is what scratches a finish; only then go over the floor with a barely-damp mop or microfibre cloth. Skip vinegar, ammonia-based glass cleaners and bleach on any finished floor — they dull the wear layer or the polish faster than ordinary wear ever would. A pH-neutral floor cleaner, used sparingly, is the safe default across wood, laminate and SPC alike.

Solid and engineered wood floors

These are the floors most sensitive to how you clean them, because the core is genuine timber underneath the finish. Never let water sit on a wood floor — wipe spills immediately, and never use a wet mop, steam cleaner or a bucket-and-slosh approach; the moisture that gets past the finish is what causes cupping, gaps and lifted boards. Use furniture pads under every chair and table leg, since a dragged chair leg is one of the most common causes of scratches we see on wood floors brought in for refinishing advice. Keep direct, all-day sun off a wood floor where you can — sheer curtains or blinds during peak afternoon hours slow the fading and drying-out that comes with continuous sunlight, which matters again through Kolkata’s long dry stretches. Re-polishing or re-sealing every few years, rather than waiting until the finish has visibly worn through, protects the timber underneath far more cheaply than a repair later.

SPC flooring: the easiest to maintain, not the impossible-to-damage one

SPC’s mineral core does not swell or warp from water, which is exactly why we recommend it for kitchens, balconies and ground-floor flats in older Central and North Kolkata buildings. That waterproof core does not mean the floor is maintenance-free, though. Grit is still the enemy of the wear layer — a doormat at every entrance, swept or vacuumed regularly, does more for an SPC floor’s long-term shine than any cleaning product. Avoid abrasive scrubbing pads and strong solvents on the surface, since they can dull the printed decor layer even though they cannot damage the core underneath. And while a spill will not swell an SPC plank the way it would laminate, water that sits in the joints for days can still reach the sub-floor beneath it, so mop up promptly rather than treating “waterproof” as “ignore it.” Our own click-lock range is supplied with StainProtect and ScrapeGuard treatments precisely to make everyday cleaning easier, but a damp mop and a neutral cleaner remain the routine that keeps it looking new.

Laminate floors: the one rule that matters most

Laminate’s high-density fibreboard core is what makes it look and feel warm underfoot, and it is also the one weak point in its care. Water that reaches the core through a seam or a plank edge swells it permanently — there is no reversing it, only replacing the affected boards. That makes the routine simple: dry-mop or vacuum for daily upkeep, use only a barely damp cloth for spills and marks, and wipe up any liquid the moment it happens rather than leaving it to dry on its own. Avoid steam mops entirely on laminate; the heat and moisture combination is exactly what the core cannot tolerate. Felt pads on furniture legs and a no-shoes policy near the entrance both go a long way toward keeping the melamine wear layer from scratching before its time.

A simple monsoon-season routine

June through September deserves its own habits, whatever floor you have. Keep a dry mat or two just inside every external door to catch water before it ever reaches the floor. Wipe umbrella drips and wet footprints promptly rather than letting them air-dry on wood or laminate. Run exhaust fans or keep a room lightly ventilated where practical, since stagnant humid air is what drives the swelling and the musty smell that follows it on wood-based floors. And check under large rugs and mats occasionally — trapped moisture underneath a rug is a common, easily missed cause of localised damage that only shows up once the rug is moved.

When it is worth calling a professional

Ordinary scuffs and light scratches on wood or engineered floors usually respond to a touch-up polish or a localised refinish rather than a full replacement. A cupped or visibly lifted board, though, means moisture has already reached the core, and that is a job for a flooring technician who can assess how far it has spread before it is sealed back over. On SPC and laminate, a plank that has come unlocked at a seam is often a quick fix rather than a full re-lay, provided it is looked at before foot traffic works it looser. If you are unsure whether what you are looking at is cosmetic or structural, a quick photo sent over WhatsApp to our flooring consultant is usually enough for an honest first opinion before you decide whether to call anyone out.

Frequently Asked Questions

Can I mop my floor every day in Kolkata’s humidity?
Yes, but the mop should be damp, not wet, on wood, engineered wood and laminate floors, since standing water is what causes the real damage, not moisture in the air. SPC tolerates a wetter mop far better because its core cannot swell, but wiping up promptly is still good practice everywhere.

Is SPC flooring completely maintenance-free?
No floor is entirely maintenance-free. SPC is the easiest of the four common types to look after because its core will not swell or warp, but grit, harsh chemicals and standing water in the joints can still dull the surface or reach the sub-floor over time, so a regular damp-mop routine still matters.

What is the biggest mistake people make cleaning wood or laminate floors?
Using too much water, whether from a soaked mop or a steam cleaner. Both wood and laminate have cores that swell permanently once water gets past the surface finish, and that damage cannot be reversed — only the affected boards can be replaced.

How do I stop my floor from getting scratched by furniture?
Felt or rubber pads under every chair, table and sofa leg, replaced when they wear thin, prevent the great majority of scratches we see from dragged furniture. A doormat at each entrance to catch grit before it is walked in helps just as much on SPC and laminate.

My wood floor has small gaps that open up in winter and close in the monsoon — is that normal?
Yes, that seasonal movement is normal for solid and, to a lesser extent, engineered wood in a climate like Kolkata’s, and it is not a defect. It becomes a concern only if the gaps are large, uneven, or the boards visibly cup or lift, which points to moisture reaching the core rather than ordinary seasonal movement.

Do you offer floor cleaning or maintenance visits at Avikar?
We advise on care at the time of installation and by WhatsApp afterwards, and our flooring consultant can assess a specific problem from photos or an on-site visit. Avikar’s own click-lock flooring carries a five-year warranty, and we are glad to talk through a care issue on an existing Avikar floor at any time.
