The Best Maid Cleaner and Housekeeper Near Me in Montreal North

From finished family rooms to forgotten storage nightmares — we handle the space you avoid

Let’s Be Honest About Your Basement

We both know why you’re here. That downstairs space? It’s become the family shame. The “I’ll deal with it later” zone. The place where holiday decorations go to die, where that weird smell originates, where you send guests you don’t really like.

I’ve been cleaning basements across Montreal, Laval, and Longueuil for 15 years. I’ve seen finished basements that just need TLC. I’ve seen unfinished concrete caves that haven’t been touched since 1987. I’ve seen mold, I’ve seen water damage, I’ve seen things growing in corners that definitely shouldn’t be.

Here’s the truth: Your basement isn’t hopeless. It just needs someone who knows what they’re doing, with the right equipment, and without judgment.

Why Basements Are Different (And Why Most Cleaners Won’t Touch Them)

Regular house cleaners? They often skip basements entirely. Or they do a quick vacuum and call it done. That’s not cleaning — that’s pretending.

Basements in Montreal present unique challenges that require specific knowledge:

• The humidity factor: Our summers are sticky, our winters create condensation. Basements here battle moisture constantly. Regular cleaning products don’t cut it. We use mold-preventative treatments and dehumidification strategies.
• The concrete reality: Unfinished floors, exposed joists, ancient insulation. You can’t just mop concrete like hardwood. Wrong approach traps dirt, wrong products create dust clouds.
• The storage maze: Most basements are 40% storage. We work around your boxes, or help you reorganize if that’s part of the plan. We don’t just clean around the clutter — we address it.
• The “I don’t know what’s down there” fear: Old paint cans, mysterious stains, things that scurry. Our teams are trained, equipped, and honestly, pretty unflappable at this point.

What “Reliable Basement Cleaning” Actually Means Here

When we say we clean basements, here’s the breakdown — no vague promises:

The Assessment (Free, Actually Useful)

Before we touch anything, we look. Is this a finished basement with drywall and flooring? Unfinished utility space? Post-flood recovery? Each requires completely different approaches.

We check for:

• Moisture issues or active leaks
• Mold presence (surface vs. structural)
• Type of flooring (concrete, vinyl, laminate, carpet)
• Ventilation quality
• What you’re actually using the space for

This isn’t a sales tactic. It’s how we avoid promising $200 cleaning for a space that needs $2,000 restoration. I’d rather be honest upfront than disappoint you later.

Standard Basement Cleaning (Finished Spaces)

If your basement’s more of a hangout spot – like a family room, gym, or home office – here’s what we’ll do:

Basic Cleaning:

• We’ll dust off all surfaces. This covers everything from the ceiling fixtures to the beams.
• Vacuuming will happen with a HEPA filter since basements often trap allergens. We’re not just moving dust around; we’re collecting it!
• The floors will get a good clean based on what they’re made of (don’t worry, we won’t damage your laminate with too much water).
• We’ll clean the windows and their wells because a little natural light makes a big difference.
• And we’ll pay attention to the baseboards and trim to make sure everything looks neat.

What You Might Forget:

• We’ll sneak behind the furniture you never move.
• Under the area rugs that have been in place for ages will also get some love.
• We’ll clean out the dehumidifier (trust me, it can get pretty gross).
• Lastly, those vent covers and returns we’ll check to remove the dust that collects there.

Time Frame: On average, this takes about 3-5 hours for a typical finished basement that’s around 600-1,000 sq ft.

Deep Basement Restoration (Neglected or Unfinished Spaces)

For those basements that look like they haven’t been touched in a year or are still unfinished, here’s the plan:

In-Depth Cleaning:

• We’ll start with a deep clean of the concrete floors, getting rid of any grease and dirt.
• The walls will be washed too, whether they’re concrete blocks, painted, or sealed.
• Cobwebs can be found in all kinds of nooks, so we’ll clear them out from joists, pipes, and every corner.
• If you need help organizing, we can move boxes and clean underneath, plus help you figure out what to keep and what to toss.
• We’ll also check and clean the ducts and vents.

Moisture and Odor Control:

• If there’s any mold or mildew, we’ll treat it (for serious issues, we’ll connect you with specialists).
• We’ll use treatments to neutralize odors instead of just covering them up.
• Plus, we’ll suggest ways to keep humidity in check moving forward.

Focus on Safety:

• Any signs of spiders or pests will be taken care of.
• We’ll spot any sharp objects or hazards that might be lying around.
• And we can dispose of any forgotten items that might be lurking in the corners.

Time Frame: Cleaning can take anywhere from 4-8 hours, depending on the space’s size and how messy it is. In some tough cases, we might need to come back for another session.

Post-Event Basement Recovery

Flooding, sewage backup, renovation aftermath — these aren’t regular cleaning. They’re recovery missions:

Water damage response:

• Initial assessment of salvageable vs. lost
• Surface water extraction coordination
• Anti-microbial application to prevent mold establishment
• Debris and damaged material removal
• Preparation for professional drying equipment

Post-renovation cleanup:

• Construction dust removal (this stuff gets everywhere — joists, pipes, every crevice)
• Paint and adhesive spot removal from floors
• Final polish before you refurnish

Important note: For active flooding or sewage, we coordinate with restoration specialists. We don’t pretend to be what we’re not. But once the emergency work is done? We make it livable again.

The Specific Tasks Nobody Talks About

Here’s what actually happens during basement cleaning that separates professionals from amateurs:

• The dehumidifier service: Emptying, cleaning reservoirs, checking filters. This machine is your basement’s lungs. We treat it accordingly.
• The sump pump check: Not plumbing work, but visual inspection. Is it functioning? Is the pit clean? Early warning signs matter.
• The window well excavation: Leaves, debris, sometimes small animal nests. These block emergency exits and create moisture entry points.
• The electrical panel dusting: Yes, carefully, with proper equipment. Dust buildup here is a fire hazard most people ignore.
• The storage system evaluation: Are your boxes on pallets? Directly on concrete? We advise on moisture protection while we clean around your belongings.
• The stair detail: Often the dirtiest part. We scrub railings, treads, risers — the full path down.

Who Actually Needs This (Real Talk)

• The “we’re finishing the basement” family — Pre-renovation cleaning to assess what you’re working with. Post-renovation to remove construction chaos. We do both.
• The inherited house situation — You bought grandma’s place in Laval. The basement is a time capsule from 1973. We help you sort, clean, and reclaim without emotional overwhelm.
• The home seller — Nothing kills a sale faster than a scary basement. We make it presentable, odor-free, and inspection-ready.
• The allergy sufferer — Basements harbor mold spores, dust mites, rodent dander. Regular professional cleaning with HEPA filtration actually improves whole-house air quality.
• The remote worker with a basement office — You spend 8 hours a day down there. It should be healthy, not slowly making you sick.
• The “something smells and I can’t find it” homeowner — We’ll find it. Usually. And clean it properly.

Equipment That Matters (Because Your Vacuum Can’t Handle This)

Consumer-grade equipment fails in basements. Here’s what we bring:

• Commercial HEPA vacuums: Sealed systems that capture particles as small as 0.3 microns. Basement dust is finer, older, more allergenic. We contain it.
• Steam cleaning systems: For concrete, tile, and sealed surfaces. Kills mold spores without chemicals, lifts years of ground-in dirt.
• Industrial dehumidifiers: For post-cleaning moisture control. We don’t just clean and leave — we set conditions for staying clean.
• HEPA air scrubbers: During intensive cleaning, we filter the air continuously. Protects our team, protects your upstairs air quality.
• Specialized concrete cleaners: pH-balanced, non-acidic formulations that clean without degrading your floor over time.
• Mold remediation PPE and containment: For situations requiring it. We don’t mess around with respiratory hazards.

The Process: From Your Call to a Usable Basement

• Step 1: The conversation You call or text. I ask specific questions — size, condition, finished or unfinished, any known issues. Sometimes I request photos. This determines if we’re the right fit, or if you need a restoration company first.
• Step 2: The honest quote Based on actual square footage and condition, not guessing. Range provided if variables exist (like “how much stuff is down there”). No hidden fees for “surprise” dirtiness.
• Step 3: Preparation guidance We tell you exactly what to do beforehand — if anything. Sometimes it’s “clear a path.” Sometimes it’s “don’t touch anything, we’ll handle it.” Depends on the job.
• Step 4: The work Team arrives with appropriate equipment. Communication throughout if you’re home. Respect for your belongings and your space. We work methodically — no rushing, no cutting corners.
• Step 5: The reveal Walkthrough with you. Explanation of what we found, what we did, recommendations for maintenance. Sometimes it’s “this looks great now, here’s how to keep it.” Sometimes it’s “you have a moisture problem developing — here’s who to call.”
• Step 6: Follow-up Check-in within 48 hours. Did anything resurface? Any concerns? We stand behind the work.

Smart Solutions for Every Space (2026 Style)

So, basement cleaning isn’t really a one-size-fits-all deal. Here’s how we break it down:

Maintenance Cleaning (for finished basements, done on a regular schedule)

• $150-$250 per visit for average-sized spaces (around 500-800 sq ft)
• You can set it up for bi-monthly or quarterly visits
• We offer discounts if you bundle it with a whole-house service

Deep Cleaning (for neglected or unfinished spaces)

• $200-$400, depending on how messy it is and how big the area is
• This can be a one-time thing or an annual “reset”

Intensive Restoration (for spaces that are really neglected or after something like a big flood)

• $400-$800+
• We’ll give you a custom quote once we check it out
• Sometimes it takes more than one session to get it just right

What impacts the price:

• Size of the area (that’s a given!)
• How much stuff we have to work around
• Any mold or water damage that needs treatment
• How easy it is to get to (think narrow stairs or low ceilings)
• Where you are located within our service area

What’s included: Labor, equipment, standard cleaning products, and getting rid of normal junk.

What’s not included: Disposal of hazardous materials (like old paint or chemicals), structural repairs, and full-on mold remediation (we can treat surfaces, but we don’t do full mold fixes).

Service Area: Where We Actually Go

• Montreal — All boroughs. Downtown condos with storage lockers, Plateau duplex basements, NDG bungalow lower levels. We know the parking challenges, the narrow stairs, the quirks.
• Laval — Chomedey, Sainte-Dorothée, Vimont, Auteuil, Fabreville. Newer construction with finished basements, older areas with classic Montreal-style semi-basements.
• Longueuil — Vieux-Longueuil, Saint-Hubert, Greenfield Park. Mix of historic homes and new builds, each with basement personalities.
• South Shore — Brossard, Boucherville, Saint-Lambert. Growing areas, many home offices in basements needing regular care.
• North Shore — Repentigny, Terrebonne, Mascouche, Blainville. Larger homes, often more square footage to address.

Outside these areas? Contact Maids Montreal and ask. Depending on the job size, we sometimes travel further.

The Questions I Get (And Real Answers)

“Can you make my basement smell normal?”

Usually, yes. Musty smells come from mold, mildew, or stagnant air. We treat the source, not cover it with fragrance. If the smell persists after our cleaning, you likely have an active moisture problem needing repair.

“Will you move my stuff?”

We work around what we can, clean under what we can lift. For major reorganization, we offer that as add-on service. We’re cleaners, not professional organizers, but we’re practical about getting to surfaces.

“Is it safe to clean around my furnace/water heater?”

Absolutely — with proper training, which we have. We clean these areas carefully, improving efficiency by removing dust buildup. We don’t disassemble anything, but surface cleaning helps performance.

“What if you find mold?”

We assess. Surface mold on non-porous materials, we treat. Extensive mold, porous materials affected, or HVAC contamination — we stop and refer you to certified mold remediation. Your health isn’t worth risking for a cleaning invoice.

“How often should a basement be professionally cleaned?”

Finished basements used as living space: every 2-3 months. Unfinished utility basements: twice yearly deep cleans. If you have allergies, humidity issues, or pets downstairs: monthly.

“Can you clean my basement apartment?”

Yes — common in Montreal. We treat rental units with the same thoroughness, coordinating with tenants or landlords as needed.

Why “Reliable” Isn’t Just a Word for Us

In this business, reliability means showing up when scheduled, doing what was promised, and being accountable. Here’s how we actually deliver:

• Consistent teams: Same cleaner(s) return for subsequent visits. They learn your space, remember your preferences, notice changes.
• Real scheduling: Specific arrival windows, not “sometime Tuesday.” Respect for your time.
• Communication: Text updates when en route. Easy reachability if plans change. No ghosting.
• Accountability: If something’s not right, we fix it. If we break something (rare, but happens), we replace it. No arguments.
• Honesty about limits: We don’t promise miracles. Some basements need contractors, not cleaners. We tell you which yours is.
