Exterior painting is one of the most visible and impactful maintenance projects a Strata council will undertake. Here's everything you need to know — from surface preparation and paint selection to budgeting, contractor evaluation, and long-term maintenance.
The exterior appearance of a Strata building is the first thing residents, visitors, and potential buyers notice. Faded, peeling, or deteriorating paint doesn't just look bad — it signals deferred maintenance, reduces property values, and leaves building materials exposed to the moisture-intensive Lower Mainland climate. A well-planned and professionally executed exterior painting project protects your building envelope, enhances curb appeal, and demonstrates to owners and the broader market that the Strata council takes stewardship of the property seriously.
Most depreciation reports for Lower Mainland Strata buildings recommend exterior painting every 7-12 years, depending on the building's exposure, substrate materials, and the quality of the previous paint job. South and west-facing elevations typically deteriorate faster due to UV exposure and driving rain, while north-facing walls may develop mold and algae growth that degrades paint film from the biological side. Understanding your building's specific exposure patterns helps the council plan painting cycles that maintain continuous protection without wasting money on premature repainting.
The planning process for a Strata exterior painting project should begin 12-18 months before the anticipated start date. This timeline allows for proper budgeting, specification development, competitive bidding, and scheduling during optimal weather windows. In the Lower Mainland, the painting season runs from approximately May through October — though June through September offers the most reliable conditions. Exterior paint requires dry conditions and temperatures above 10°C for proper application and curing, and the Lower Mainland's shoulder seasons can be unpredictable.
Surface preparation is the single most important factor in the longevity of an exterior paint job — and it's where shortcuts cause the most problems. Professional surface preparation for Strata buildings includes pressure washing all surfaces to remove dirt, mildew, loose paint, and atmospheric contaminants. Power washing must be done carefully on wood substrates to avoid raising grain and on stucco to avoid driving water behind the cladding. After washing, surfaces must be allowed to dry completely — typically 48-72 hours in Lower Mainland conditions.
Scraping and sanding follow the pressure wash. All loose, peeling, or flaking paint must be removed to sound substrate. On wood siding, this may involve hand scraping, mechanical sanding, or in severe cases, chemical stripping. On stucco and concrete, deteriorated areas must be patched and cured before painting. Caulking of all joints, seams, gaps around windows and doors, and transitions between different materials is critical — failed or missing caulking is a primary moisture entry point that paint alone cannot seal.
For Strata buildings with fiber cement siding (James Hardie or similar), preparation requirements differ from wood. Fiber cement is dimensionally stable and doesn't expand and contract like wood, so paint adhesion is generally excellent on properly prepared surfaces. However, fiber cement does absorb moisture, and painting over damp material leads to blistering and peeling. Factory-primed fiber cement that has been exposed to weather for more than 180 days requires re-priming before topcoating.
Paint selection for Lower Mainland Strata buildings should prioritize three qualities: moisture resistance, flexibility, and mildew resistance. Premium 100% acrylic latex paints dominate the exterior market for good reason — they breathe (allowing trapped moisture to escape), remain flexible through temperature cycling, resist mildew growth, and clean up with water. Within the acrylic category, look for products specifically formulated for coastal Pacific Northwest conditions. Major manufacturers including Benjamin Moore, Sherwin-Williams, Dulux, and Cloverdale Paint all offer premium exterior lines with extended warranty coverage.
Color selection for Strata exterior painting involves both aesthetic and practical considerations. Strata councils must balance owner preferences, neighborhood standards, and in some municipalities, design guidelines. Lighter colors reflect more UV radiation and generally last longer between repaints, while darker colors absorb heat and may cause expansion issues on wood substrates. Many Lower Mainland Strata buildings use a multi-color scheme — a body color, trim color, and accent color — that provides visual interest and breaks up large building facades. Before committing to colors, apply test patches on different elevations and evaluate them at different times of day and in different lighting conditions.
The competitive bidding process for Strata exterior painting should include a minimum of three qualified painting contractors. Each bidder should receive identical specifications that detail surface preparation requirements, paint products and number of coats, areas to be painted (including or excluding specific elements like decks, railings, garage doors, etc.), schedule requirements and phasing, and warranty terms. The specification should clearly define what constitutes acceptable surface preparation — this is where most disputes between councils and painting contractors arise.
When evaluating painting bids for a Lower Mainland Strata building, look beyond the bottom line price. Key evaluation criteria include the contractor's experience with Strata buildings of similar size and construction, their proposed preparation methods and time allocation (preparation should account for 50-70% of the total labor on a repaint project), paint products specified and whether they match the specification, crew size and estimated duration, access methods (scaffolding, swing stages, lifts, or a combination), insurance coverage and WorkSafeBC compliance, warranty terms covering both materials and workmanship, and references from recent Strata painting projects.
Cost ranges for Lower Mainland Strata exterior painting vary based on building size, height, complexity, substrate condition, and access requirements. As general 2025 guidelines: low-rise wood-frame townhouse complexes typically cost $3-$6 per square foot of painted surface area; mid-rise buildings (4-6 stories) range from $5-$10 per square foot due to access equipment requirements; and buildings requiring swing stage access or specialized safety measures command $8-$15 per square foot. For a typical 50-unit Strata complex, total exterior painting costs typically range from $80,000 to $250,000 depending on these factors.
Project management during execution requires active oversight. Designate a council member or property manager to serve as the primary liaison with the painting contractor. Establish a daily communication protocol, conduct regular progress inspections, and document any issues or change orders in writing. Resident communication should include advance notice of the schedule for each building or phase, any parking restrictions or access changes, windows that should remain closed during painting, and expected noise levels from pressure washing and preparation work.
Weather management is an ongoing concern during Lower Mainland exterior painting projects. Rain interruptions are inevitable even during the best months, and the painting contractor should have a weather contingency plan that minimizes delays while protecting work in progress. Fresh paint that gets rained on before proper curing can wash off, leave water marks, or fail to develop proper film hardness. Professional contractors monitor weather forecasts closely and sequence work to minimize weather risk — painting west-facing walls early in the day before afternoon sun causes the paint to dry too quickly, and scheduling preparation work during marginal weather days while reserving ideal conditions for painting.
Sustainability and environmental considerations are increasingly important for Strata exterior painting projects. Low-VOC and zero-VOC paint formulations are now widely available from major manufacturers without significant performance compromise. Proper containment and disposal of paint waste, lead abatement for pre-1980 buildings (lead-based paint was not banned in Canada until 1976), and environmentally responsible pressure wash water management are all considerations that responsible contractors address in their proposals.
Post-painting maintenance extends the life of the investment and defers the next painting cycle. Annual inspections should check for early signs of paint failure — blistering, peeling, cracking, or fading — particularly on high-exposure elevations. Touch-up painting of small areas of damage or wear prevents moisture intrusion that leads to substrate damage and expanded repainting scope. Cleaning — light pressure washing or soft washing — every 2-3 years removes atmospheric contaminants and biological growth that degrade paint film. Caulking inspection and replacement should be part of the annual building maintenance program, as caulking typically fails before paint and leaves gaps where moisture enters the building envelope.
