Pacific Gate Asset Stability Index™
A proprietary 100-point diagnostic that measures your unit's Hygiene & Material Degradation Risk across four scientific vectors — stack effect, chloride corrosion, HVAC particulate, and biofilm persistence.
Answer four questions below for your preliminary PG-ASI score. The official 100-point score requires an in-person Clinical Director walkthrough.

Unit Elevation Zone
Your floor range determines particulate concentration via the Stack Effect Neutral Pressure Plane and street-level intake vectors.
What floor range is your unit on?
The Science Behind Your Score
4 Vectors of Material Degradation
Pacific Gate sits in an ASTM C5 extreme marine zone at 41 stories. These four forces act on your unit simultaneously — and conventional cleaning makes all of them worse.
Stack Effect Particulate
25 ptsIn a 600-ft building, ~2 inches of water column pressure difference drives street-level contaminants (I-5 brake dust, construction silica) upward through elevator shafts and into upper-floor HVAC intakes. Units above the neutral pressure plane (floors 18–22) receive the highest concentration.
Coastal Chloride Deposition
25 ptsDamp-dry cycling deposits a conductive chloride electrolyte film on brushed stainless steel, glass, and lacquer finishes. Each cycle concentrates NaCl and MgCl₂ ions, breaking the passive chromium oxide layer on Sub-Zero and Wolf hardware — initiating pitting corrosion invisible until irreversible.
HVAC Particulate Redistribution
25 ptsBuilding MERV-8 to MERV-11 filters cannot capture 0.3-micron particles — the Most Penetrating Particle Size (MPPS). These particles pass through the filtration valley and deposit on glass, millwork, and stone via electrostatic attraction. Dry wiping resuspends them within 4–6 hours.
Wet-Zone Biofilm Persistence
25 ptsBiofilms like Serratia marcescens produce EPS matrices that resist chemical disinfectants 10–1,000x more effectively than planktonic bacteria. San Diego's hard water (18–22 grains/gallon) co-deposits calcium, creating calcified biofilm that only 275°F Thermal Shock can fracture.
Pacific Gate Asset Stability Index FAQs
The PG-ASI is a proprietary 100-point diagnostic designed exclusively for Pacific Gate (1388 Kettner Blvd) residents. It evaluates four scientific vectors: Stack Effect Particulate, Coastal Chloride Deposition, HVAC Particulate Redistribution, and Wet-Zone Biofilm Persistence. The official score requires an in-person Clinical Director walkthrough — the preliminary risk profile above identifies your highest-exposure vectors based on unit characteristics.
The full 100-point assessment is performed during your first Clinical Asset Reset (Deep Clean), starting at $325 + $25 Downtown Logistics Fee. This includes $2M COI filing with Pacific Gate management, freight elevator staging, and photographic documentation of all findings. View full pricing.
Pacific Gate is a 41-story tower in an ASTM C5 extreme marine zone. Stack-effect pressure differentials pull street-level contaminants upward, chloride damp-dry cycling corrodes premium hardware, HVAC systems redistribute 0.3-micron particles, and sustained humidity fuels biofilm colonies. Standard cleaning redistributes these contaminants — our protocol extracts them. View our Pacific Gate services →
