Waterproofing is largely preventive — protecting a structurally sound balcony from future water intrusion. Repair means something has already failed, and coating over it without addressing the underlying issue doesn't fix the problem — it just hides it until it resurfaces, usually worse and more expensive.

If your board is dealing with a report or resident complaint describing actual damage rather than "let's get ahead of maintenance," you're likely looking at a repair scope rather than a straightforward recoat.

• Soft or spongy decking underfoot — usually indicates rot or delamination in the substrate below the surface
• Visible cracking, especially concentrated near drains, wall transitions, or the balcony's outer edge
• Water staining on the ceiling of the unit below — a clear sign water has already gotten past the waterproofing layer
• Peeling or bubbling coating — often a sign of trapped moisture pushing up from underneath
• Standing water that doesn't drain within a few hours after rain — a drainage or slope issue that recoating alone won't fix
• Visible movement or bounce when walking across the balcony — this can indicate a structural issue that needs immediate attention, not scheduling flexibility

If a board is seeing any of these across multiple units or buildings, it's often worth a broader inspection rather than addressing balconies one complaint at a time.

1. Damage assessment — determining whether the issue is isolated to the coating, the substrate, or the structural framing itself
2. Scope definition — a clear, written explanation of what's actually wrong and what fixing it involves, so the board understands the "why" behind the cost
3. Repair work — addressing rot, delamination, or structural compromise before any new waterproofing goes down
4. Waterproofing reapplication — once the underlying issue is resolved, the balcony gets a proper waterproofing system, not just a cosmetic patch
5. Documentation — a record connecting the original damage to the completed repair, useful for board records or future SB 326 inspections

If one balcony on a property shows damage, it's worth asking whether it's isolated or a sign of a building-wide construction or maintenance pattern. Buildings from certain eras or with certain original waterproofing systems tend to show similar failure patterns across multiple units around the same time. We'll flag this for the board if we see it — it's more cost-effective to address a pattern proactively than balcony by balcony as each one fails.
