Montreal apartments are famous for their original hardwood floors. Walk into any pre-war triplex in the Plateau, a 1920s flat in Outremont, or an Edwardian duplex in Rosemont, and you will likely find quarter-sawn oak or sugar maple boards that are 80 to 130 years old. These floors survived decades of tenants, Montreal winters, and summer humidity cycles not because they are indestructible — they are not — but because previous generations treated them correctly.
Modern tenants often make four mistakes that damage or cloud these floors within months: using steam mops, cleaning with vinegar, applying Murphy's Oil Soap, and over-wetting with a soaking wet mop. Each of these methods is perfectly fine on ceramic tile, vinyl, or laminate. On original hardwood, each one is a slow disaster.
This guide covers everything you need to know about cleaning and maintaining hardwood floors in a Montreal home, from understanding which floor type you have to the seasonal protocol that matches our humidity swings.

Understanding Your Hardwood Floor Type
Not all wood floors are the same, and the right cleaning method depends on what you have underfoot.
Solid hardwood (pre-war and interwar homes): If you live in a triplex, duplex, or row house built before 1950, your floors are almost certainly solid wood — typically ¾-inch white oak, red oak, sugar maple, or Douglas fir. The boards may be narrow-strip (1.5–2.25 inches wide) or wide-plank (3–5 inches). Many have their original oil or shellac finish, which is more porous than modern polyurethane and reacts badly to water and acidic cleaners.
Engineered hardwood (1970s–1990s condos and renovations): A thin veneer of real wood (typically 1–3 mm) bonded to a plywood or HDF core. Looks like solid hardwood but tolerates slightly more moisture variance. Still requires pH-neutral cleaning — the veneer will delaminate with excessive water.
LVP and laminate (new-build units, post-2000 condos): Luxury vinyl plank and laminate are not hardwood. They are far more tolerant of moisture. These floors can handle more water, and most internet cleaning advice is written with LVP or laminate in mind. If your building was completed after 2005, you may have LVP rather than hardwood.
How to check: Press a fingernail into an inconspicuous spot. Real hardwood dents slightly and shows a brown wood core. LVP has a plastic core and will not dent. Laminate shows a photographic layer over a grey fiberboard core.

What NOT to Use on Montreal Hardwood Floors
This section is the most important in the guide. More Montreal hardwood floors are damaged by the wrong cleaner than by neglect.
Vinegar and water solutions: Vinegar is acidic (pH 2–3). Hardwood finish — whether polyurethane, oil, or shellac — breaks down under repeated acid exposure. The floor may look clean after the first few applications, but within 6–12 months the finish becomes dull, cloudy, and micro-porous. Once the finish is compromised, water and dirt penetrate the wood itself. Vinegar cannot be rinsed out of a stripped finish.
Steam mops: Steam mops inject moisture and heat directly into wood grain. The wood fibres absorb the steam, swell, then contract when they dry. Over time this cycle causes cracking, cupping (boards curving upward at the edges), and warping. In a Montreal apartment with baseboard heating and low winter humidity, a steam-mopped floor can cup noticeably within one or two seasons.
Murphy's Oil Soap and oil-based soaps: Murphy's Oil Soap is designed for raw, unfinished wood. On finished hardwood it leaves a wax residue that builds up into a sticky, dull film. Stripping this film typically requires sanding. Many tenants and homeowners have had to refinish their floors after using it regularly for several years.
Soaking wet mops: Standing water on hardwood penetrates grain lines between boards, swells the wood, and eventually causes black staining and mildew in the subfloor. Use a barely damp mop — you should not see any moisture trail left on the floor after the mop passes.

Supplies You Need
- Dry microfibre dust mop with a 45–60 cm head (a broom scatters dust rather than trapping it)
- HEPA-filter vacuum with a hard-floor setting (turn off the beater bar or use the bare-floor attachment)
- Microfibre flat mop
- pH-neutral hardwood floor cleaner (Bona Hardwood Floor Cleaner, Method Wood Floor Cleaner, or any product with pH 6.5–7.5 and no wax, no oil, no vinegar)
- Two clean microfibre cloths for spot work
- Warm water in a bucket (not hot)
A spray-and-go product like Bona Squirt + Mop is ideal for Montreal apartments because it applies the right amount of liquid — barely damp — without any measuring.

Step-by-Step Cleaning Method
Step 1 — Dry sweep (daily or every 2–3 days)
Drag the microfibre dust mop across the floor in the direction of the wood grain. The static charge in the microfibre traps fine particles — sand, grit from Montreal streets, and dry debris — that would scratch the finish if pushed around with a wet mop. In winter, the salt and sand tracked in from outside are abrasive enough to micro-scratch polyurethane within weeks if not swept daily.
Step 2 — Vacuum (weekly)
Run the vacuum on the hard-floor setting. Pay special attention to the gaps between boards, where grit accumulates and eventually works its way under the edges. Use a crevice attachment along baseboards and corners.
Step 3 — Damp mop (weekly or bi-weekly)
Apply a fine mist of pH-neutral hardwood cleaner to a 1–2 square metre section (or spray directly onto the flat mop pad). Mop in the direction of the grain with light pressure. The mop pad should feel damp, not wet. Move to the next section immediately — never let any liquid pool on the surface.
Work from the far corner of the room toward the exit so you are never stepping on the freshly cleaned section. Two passes are sufficient — more liquid is not better.
Step 4 — Dry the floor
In most cases, a well-wrung microfibre flat mop leaves the floor dry within 60–90 seconds. If you can see a damp sheen lasting longer than 2 minutes, your mop pad is too wet. Ring it out more thoroughly or reduce the amount of cleaner applied.

Montreal Seasonal Protocol
Summer (June–August): Humidity season
Montreal summers bring relative humidity of 65–85%. Hardwood absorbs atmospheric moisture and expands. During this period:
- Reduce mop-cleaning frequency to once every 10–14 days (less cleaning, less added moisture)
- Keep windows open at night if outdoor humidity is below 60%; use a dehumidifier if indoor humidity consistently exceeds 80%
- Check for cupping along board edges — a small consistent gap between boards is normal seasonal movement; boards resting edge-on-edge with the centre lower than the edges indicate excess moisture
Fall transition (September–October)
This is the ideal time for a deeper clean before the heating season begins. Sweep and vacuum thoroughly, then mop with a slightly more dilute cleaner than usual. Inspect the finish for cloudiness or dull patches — these may indicate water penetration from summer and should be addressed before winter contracts the boards further.
Winter (November–March): Dry-air season
Forced-air heating and electric baseboard heaters drop indoor humidity to 20–35% in Montreal apartments. This causes boards to contract and produce hairline gaps between them — especially common in pre-war homes with wide-plank original floors. This is normal and reversible.
- Add a humidifier or a pot of water on the baseboard heater to maintain 35–45% RH indoors
- In extremely dry periods, reduce mopping to once every three weeks — the floor needs less water removal when ambient humidity is already low
- Do not use any filler (wood putty, wax sticks) in winter gaps — they close again in summer and will crack or pop the filler out
Spring (April–May): Road salt season
Boards swell back as humidity rises and winter gaps close on their own. But spring is also when Montreal road salt and sand reach peak concentration inside apartments, tracked in on boots and carried on the bottoms of bags. The mineral grit from de-icing products (calcium chloride, magnesium chloride, sand) is the primary cause of premature finish wear in Montreal apartments. Sweep and vacuum daily in April.

Dealing With Stains
Food and drink spills: Blot immediately with a dry cloth. Never rub — rubbing spreads the stain and pushes liquid deeper into the grain. After blotting, apply a small amount of pH-neutral hardwood cleaner and wipe with a slightly damp cloth in the direction of the grain. Dry immediately.
Salt and mineral residue (white haze on boards): A barely damp microfibre cloth with plain warm water usually removes salt residue. For stubborn haze, a diluted pH-neutral cleaner on a barely damp mop will lift it. Never use vinegar to remove salt haze — the acid removes the mineral but damages the finish.
Black staining (pet accidents, old water damage): Dark black staining that penetrates below the surface finish indicates that water has oxidized the wood fibres themselves. This cannot be cleaned away — it requires professional sanding and refinishing.
Heel marks and rubber scuffs: Light marks can sometimes be removed by rubbing gently with a soft cloth and a small amount of pH-neutral cleaner. Stubborn scuffs may require a specialty hardwood floor polish applied with a very fine cloth.

Landlord and Tenant Responsibility Under Quebec TAL Law
Under Quebec's Civil Code and the Tribunal administratif du logement (TAL) framework, a tenant is responsible for maintaining the dwelling in the same condition it was in at the start of the lease, accounting for normal wear. Normal wear is legally interpreted as superficial surface dulling over a multi-year tenancy — not deep scratching, water staining, or finish removal caused by incorrect cleaning products.
This matters practically: if you use steam mops or vinegar cleaners and leave the floor cupped or with a stripped finish, a Quebec landlord can claim the repair cost from your deposit and even take the matter to the TAL. A move-out-ready floor is one that is clean, free of deep scratches, and has its original finish intact.
See our [move-out cleaning checklist](/en/blog/move-out-cleaning-checklist-montreal) and [move-in cleaning checklist](/en/blog/move-in-cleaning-checklist-montreal) for documentation guidance to protect your deposit.

When to Call a Professional Cleaning Service
The day-to-day maintenance described above is straightforward and takes 10–20 minutes per room per week. But some situations genuinely call for professional help:
Deep-clean before move-in: If the previous tenant left residue, wax buildup, or ground-in dirt, a professional clean removes it without risking damage to a floor you do not yet know.
Move-out documentation: A professional cleaning receipt and dated photographs are valuable evidence at the TAL if a landlord disputes deposit return based on floor condition.
Post-renovation cleaning: Construction dust contains fine silica particles that scratch finish on contact. After any renovation work in your apartment, have the floors professionally swept and vacuumed before damp-mopping — all grit must be fully removed first or the mopping phase grinds it into the surface. See our [post-renovation cleaning checklist](/en/blog/post-renovation-cleaning-checklist-montreal).
Annual spring deep clean: After Montreal's six-month salt season, an annual professional deep clean removes accumulated mineral residue from baseboards and board edges that regular weekly mopping cannot reach.

Frequently Asked Questions
Q: Can I use vinegar on hardwood floors in a Montreal apartment?
A: No. Vinegar has a pH of 2–3, which breaks down polyurethane and oil-based hardwood finishes over time. The floor may appear clean after the first few uses, but the finish will become dull, cloudy, and micro-porous within 6–12 months. Once the finish is compromised, moisture and dirt penetrate the wood itself. Use a pH-neutral hardwood floor cleaner (pH 6.5–7.5) such as Bona Hardwood Floor Cleaner or Method Wood Floor Cleaner instead.
Q: Is it safe to use a steam mop on Montreal hardwood floors?
A: No. Steam mops inject moisture and heat into wood grain, causing the boards to swell, then contract. In Montreal's humid summers and dry heated winters, this repeated cycle accelerates cracking, cupping (boards curving upward at edges), and warping. Steam also voids most hardwood floor warranties. Use a barely damp flat microfibre mop with pH-neutral hardwood cleaner instead.
Q: Why are there gaps in my hardwood floors in winter?
A: Gaps between boards in winter are normal seasonal movement. Hardwood contracts when indoor humidity is low — Montreal's heated apartments drop to 20–35% RH in winter. The boards expand again in spring when humidity rises. These gaps close naturally and do not require filling. A humidifier set to maintain 35–45% indoor humidity reduces gap width. Do not fill winter gaps with wood putty: in summer the boards expand, crushing the filler and creating a worse cosmetic problem.
Q: How often should I mop hardwood floors in a Montreal apartment?
A: Weekly or bi-weekly damp mopping with a pH-neutral cleaner is appropriate for most Montreal apartments. In winter, when indoor air is very dry and you are tracking in more road salt, weekly mopping is ideal. In summer, when humidity is already high, every 10–14 days is sufficient. Daily dry sweeping or dust-mopping to remove abrasive grit before it scratches the finish matters more than mopping frequency.
Q: Who is responsible for hardwood floor damage in a Quebec rental apartment — the tenant or the landlord?
A: Under Quebec TAL law, tenants are responsible for normal maintenance and for not causing damage beyond normal wear. Normal wear is superficial surface dulling over years of use. Damage caused by incorrect cleaning products (steam mops, vinegar, oil soaps), water spills left standing, or pet accidents that penetrate the finish is considered tenant responsibility. The landlord is responsible for refinishing or repairing floors damaged before the lease began or from structural causes such as water infiltration from above or subfloor issues.
Q: What is the best hardwood floor cleaner available in Montreal?
A: Bona Hardwood Floor Cleaner (available at Canadian Tire, Home Depot, and RONA across the Montreal area) and Method Wood Floor Cleaner (available at IGA, Metro, and Jean Coutu) are both pH-neutral, wax-free, and safe for all finished hardwood. Avoid any product containing vinegar, oil, wax, or silicone. Our [eco-friendly cleaning guide](/en/blog/eco-friendly-cleaning-montreal) covers green product selection in more detail for tenants who prefer certified non-toxic options.
