Exterior building maintenance services for BC strata properties.
The outside of the building is where the BC climate does its work. Coastal rainfall, freeze and thaw, UV exposure, and wind-driven water shorten the service life of every surface that faces the weather. Exterior facility maintenance is the discipline that keeps that exposure from turning into envelope damage.
Resources/Exterior maintenance
Exterior building maintenance: the items that matter most
Six categories that drive long-term building cost
The exterior items most strongly tied to long-term building cost are:
- Roof systems. Membranes, flashings, scuppers, and rooftop penetrations.
- Cladding and sealants. Siding, panel joints, window perimeters, and control joints.
- Windows and doors. Operable hardware, weatherstripping, and threshold conditions.
- Balconies and decks. Waterproofing membranes, drains, guardrails, and attachments.
- Drainage. Gutters, downspouts, perimeter drains, swales, and site slope.
- Walkways and exterior stairs. Coatings, traction, code-relevant geometry.
The items most often missed between formal reports
These are also the items most often photographed once during a depreciation cycle and then not looked at again until a leak or complaint forces the conversation. Site drainage is the most overlooked: downspout terminations, splash blocks, and slope away from the foundation routinely become the root cause of envelope water damage years later.
Where the BC climate changes exterior maintenance cycles
Coastal exposure shortens service life
Cycles published for drier climates rarely fit Greater Vancouver, the Fraser Valley, or the South Coast. Sealants intended for ten-year exposure routinely show stress at six. Roof membranes that perform well in interior BC fail earlier on west-facing slopes that take the storm track. Wood elements absorb and release moisture on a faster loop than most service intervals account for.
Let condition set the timing, not the catalogue
The practical response is not to over-engineer the schedule. It is to keep the record current, walk the building on a regular cadence, and let the building's actual condition set the timing.
How exterior findings join the rest of the building record
One ranked record, not six separate reports
Exterior maintenance is one input into the same building record SENTiNEL builds for the council. The exterior findings sit alongside interior, mechanical, and shared-system findings, ranked by severity, photographed, and tied to recommended next steps the property manager and trades can run with.
A small sealant failure stays a sealant failure
That continuity is what keeps a small sealant failure from becoming an envelope rebuild, and what keeps the depreciation report grounded in evidence the council can show at the next AGM.

Common questions about this topic.
- What counts as exterior building maintenance?
- Anything that protects the building envelope and the surfaces water and weather touch first: roofs, cladding, sealants, windows, balconies, walkways, drainage, and the site features that move water away from the foundation.
- How often should exterior maintenance be reviewed?
- Seasonally for drainage and water management, annually for envelope and roof surfaces, and on inspection cadence for sealants and transitions. Coastal BC conditions usually shorten cycles compared to drier regions.
- Who pays for exterior maintenance in a strata building?
- The strata corporation funds work on common property, including the envelope and roof of multi-unit buildings. In townhome stratas, the bylaws determine which exterior elements sit with owners and which sit with the corporation.
- What is the most overlooked exterior maintenance item?
- Site drainage. Downspout terminations, swales, splash blocks, and slope away from the building are routinely missed in formal reports and routinely show up as the root cause of envelope water damage years later.
