How much does balcony waterproofing typically cost?

Cost depends on scope, square footage, substrate condition, and how many units or buildings are involved. A single-balcony recoat runs in the low-to-mid four figures; full membrane replacement or multi-building SB 326 remediation projects vary widely based on the extent of the work. We provide a written estimate after inspection — not a phone-quote guess, since hidden moisture damage is common and can significantly change scope.

Does our HOA pay for balcony waterproofing, or does the individual unit owner?

This depends on your association's CC&Rs and whether the balcony is classified as a common element or an exclusive-use area belonging to a specific unit. Many governing documents split responsibility — structural waterproofing on one side, surface finishes or fixtures on the other — but this varies by association. We recommend confirming the specific allocation with your management company or legal counsel before finalizing a budget, since we've seen it split differently from one association to the next.

Will you help us figure out how to budget for a large project?

Yes. We provide itemized, written proposals that can be used for reserve study updates or special assessment votes, and we're happy to talk through phasing options if the full scope doesn't fit a single budget cycle.

How long does a typical balcony waterproofing job take?

A single balcony recoat usually takes 1–3 days, largely driven by cure time. Larger projects — full membrane replacement or multi-building work — are scheduled in phases and can run several weeks to a few months depending on scope and how many buildings are involved.

We have an SB 326 deadline. Can you work around it?

Generally yes, but the earlier you bring us in after receiving your inspection report, the more scheduling flexibility we have. If you're already close to a deadline, contact us as soon as possible so we can assess what's realistically achievable.

How far in advance should we schedule a project relative to our board's budget cycle?

As early as possible — ideally before your board finalizes a budget or reserve study update, so you're working with an accurate estimate rather than a placeholder number.

Do you perform the SB 326 inspection itself?

No. The inspection must be performed by a licensed architect, structural engineer, or a contractor specifically qualified to certify exterior elevated elements. We handle the repair and waterproofing work that inspection findings typically require.

We just got our SB 326 report back — what's the first step?

Send us the report. We'll review the findings with your board or management company and provide a clear breakdown of what needs to happen, along with a written scope and cost estimate.

What if some findings are urgent and others aren't?

Your inspector's report will typically classify findings by urgency. We'll help you understand what's time-sensitive versus what can be phased into a longer-term maintenance plan, though the specific legal timeline for any finding should come from your inspector or structural engineer.

What's the difference between waterproofing, repair, and membrane replacement?

Waterproofing is largely preventive maintenance on a structurally sound balcony. Repair addresses specific damage — rot, cracking, a failed section — without necessarily replacing the entire system. Membrane replacement means the full waterproofing membrane has failed broadly enough that the entire system needs to be removed and reinstalled. We'll tell you directly which category your project falls into after inspection.

Can you work across multiple buildings or associations at once?

Yes — this is standard for the property management companies and larger associations we work with. We phase multi-building or multi-property projects to manage budget timing, resident access, and crew scheduling.
