Townhomes and Shared Walls: How Exterior Cleaning Gets Coordinated
Townhomes are one of the most common housing types in the Lower Mainland, and their shared structure changes how exterior cleaning works. When the roof runs across several units and the walls are shared, cleaning is not something one owner does in isolation, it takes coordination. Here is how townhome and shared-wall exteriors are handled.
Why shared structure matters
In a townhome complex, the roof usually runs continuously across multiple units, the gutters serve shared rooflines, and the walls are shared between neighbours. That means the exterior is genuinely shared: one unit's mossy roof section or clogged gutter can affect the neighbours and the shared envelope, and cleaning one unit's roof slope in isolation often does not make sense when it is part of a continuous roof.
Most townhome exteriors are also common property under a strata, so the cleaning is a shared responsibility handled at the complex level rather than unit by unit.
How it is coordinated
The practical approach is to clean townhome exteriors as a coordinated whole, the continuous roofs, the shared gutters, and the building elevations, handled across the complex rather than one owner at a time. This is usually organised by the strata council or property manager, scheduled with resident notice and access planning, so the whole property is done consistently and nothing is missed at the boundaries between units.
Doing it complex-wide is also more efficient and cheaper per unit than fragmented, unit-by-unit cleaning, since the setup and access are shared across the whole job.
For owners and councils
If you own a townhome, exterior cleaning is usually something raised with and handled by the strata rather than arranged for your unit alone, precisely because the roof and walls are shared. For councils and managers, treating the exterior as a coordinated, scheduled job protects the shared assets and keeps the complex looking consistent.
Because complexes vary in size, layout and how the roofs and gutters run, a townhome exterior clean is scoped for the specific property, typically after a walk-through, which establishes the plan and a per-complex quote.
