Direct answer
Underground parking cleaning combines mechanical sweeping, controlled pressure washing, auto-scrubber work, wall and column washing, and site-specific logistics for shared garages. Nickel & Krome scopes each mandate around access, vehicle movement, drains, water source, residue level, and the building schedule so the garage can be cleaned without disrupting residents or operations more than necessary.
- Mechanical sweeping, pressure washing, scrubbing, walls, columns, and technical zones
- Quote inputs: spaces, levels, drains, access, water source, schedule, and residue level

· Estuaire 1 · Longueuil
Estuaire 1, Longueuil: cleaning the garage floors
On October 17, 2026, Nickel & Krome cleaned the garage floors at Estuaire 1 in Longueuil. The work covered residential levels SS-1 and SS-2 and the commercial area of SS-1. It combined manual sweeping, mechanical sweeping with the Tennant M20, pressure washing and sludge collection.

Nickel & Krome cleans underground parking garages for condo syndicates, property managers and commercial buildings in Montreal, Laval and the North Shore. Mechanical sweeping, pressure washing and floor scrubbing are selected for the surfaces and residue present.
For seasonal upkeep, a one-time clean or scheduled maintenance, we agree on the areas to clear, vehicle movement and access before the work. Floor cleaning, targeted oil-stain treatment, walls, columns and exposed piping are included according to the agreed scope.

Mechanical sweeping of parking lots and underground garages
Mechanical sweeping
Mechanical sweeping is the essential first step of a serious underground parking lot cleaning.
Our equipment allows us to quickly and efficiently recover:
The size of our machines allows us to work on large surfaces as well as in narrower areas, where manual cleaning alone becomes slow, irregular, and unprofitable.
The goal is not simply to "sweep". The goal is to remove as much material from the floor as possible before the washing stages, to improve the final result and limit the unnecessary dispatch of residues to the drains.
What our mechanical sweeping concretely brings: A parking lot better prepared for washing, a visible reduction of dust on the ground, a better quality of finish, and a cleaner environment for building users.
Covered scope
- Accumulated dust
- Salt residues
- Carbon particles
- Small rocks and abrasives
- Leaves, trash, and various dirt
- Debris present in circulation and parking zones
Service details
Pressure washing of underground parking lots
1. Reduce salt and abrasive residue accumulation · 2. Remove embedded dirt · 3. Mitigate oil stains
Pressure washing
Once the sweeping is done, we proceed to pressure wash the surfaces according to the condition of the premises, the level of dirt, and the type of soil.
Our intervention sequence is simple and logical:
Oil that has penetrated porous concrete and worn or damaged finishes may remain visible after cleaning. The expected result is assessed from the surface condition; cleaning does not repair the concrete or its coating.
Covered scope
- Complete mechanical sweeping
- Manual sweeping of less accessible areas
- Targeted treatment of oil stains and greasy areas
- Pressure washing of surfaces
- Finishing according to site needs

Floor scrubbing machine cleaning
Floor scrubbing machine
For certain environments, the auto-scrubber is an excellent complementary step after deep sweeping.
It is particularly useful in:
After removing debris and gross accumulations, the auto-scrubber allows for a more uniform washing of fine dust, remaining residues, and certain stubborn soils.
The desired result is a cleaner, more homogeneous, and more presentable surface, with a better finish than a simple rinse.
Covered scope
- Multi-level parking lots
- Underground garages
- Warehouses
- Factories
- Large high-traffic indoor areas
Service details
Access, traffic, drains, and quote inputs
Exposed conduits
A garage cleaning plan is only reliable when access and vehicle movement are planned before the crew arrives. We confirm whether the work should be done by level, by zone, overnight, on a weekend, or during a lower-traffic window so residents, tenants, deliveries, and security instructions remain manageable.
Water handling is agreed before work begins: drain configuration, recovery needs and the arrangements for collected water and residue. The presence of a drain alone does not determine the method. Slopes, ventilation and sensitive areas may require lower-flow passes, recovery or more mechanical scrubbing.
For a precise quote, the useful inputs are the approximate number of parking spaces, number of levels, access height, ramp configuration, drain locations, water source, residue level, oil-stain zones, wall or column scope, preferred schedule, and whether the garage can be cleared by phase. The price depends on the area, cleaning steps, access constraints and water-recovery needs.
Covered scope
- Vehicle logistics: levels, ramps, gates, access height, and temporary closures
- Method selection: mechanical sweeping, pressure washing, auto-scrubber, or targeted degreasing
- Water constraints: drains, slopes, recovery needs, ventilation, and sensitive rooms
- Completion check: lanes, corners, ramps, drains, walls, columns, and pedestrian access points

Dusting of exposed ducts
Wall and column washing
In many underground parking lots and technical spaces, exposed ducts quickly accumulate dust, dirt, and suspended residues.
Nickel & Krome dusts ducts, exposed piping, elevated surfaces, and hard-to-reach areas using equipment adapted for this type of intervention.
We aim to restore the visual cleanliness of exposed installations to:
Covered scope
- Improve the general appearance of the parking lot
- Reduce dust accumulation at heights
- Support a better overall maintenance level for the building
- Complete a more serious cleaning of technical and common areas
Service details
Washing of walls and columns
Walls, columns, and vertical surfaces in underground parking lots also accumulate dust, splashes, traffic marks, black deposits, and various dirt.
We offer wall and column washing depending on the nature of the surfaces and the level of dirt observed. This intervention significantly improves the visual aspect of the space, particularly in buildings where the perception of cleanliness is important for occupants, visitors, or managers.
A parking lot may have been washed on the ground, but if the columns and walls remain blackened or powdery, the result seems incomplete.
That's exactly what this step corrects.
Who do we serve? We intervene specifically in:
Covered scope
- Underground parking of residential towers
- Indoor garages of multi-residential buildings
- Condo parking lots
- Multi-level parking lots
- Warehouses and industrial spaces
- Certain service, loading, or indoor circulation areas

Montreal underground parking service
Service scope · Montreal garages
Garage cleaning is planned around the surfaces, drainage and vehicle circulation. For occupied garages where Montreal access, resident coordination, and local project evidence matter, use the dedicated Montreal garage service.
Service details
Garage upkeep or a construction handover?
This service covers the upkeep of garages already in use: accumulated sand, salt, dust, traffic residue and targeted stain treatment. Work can be planned by level or zone with the building manager. For a new garage or construction residue before occupancy, see our post-construction parking cleaning service, which is planned around the remaining trades and handover date.
