HOA & Multi-Family Building Envelope Emergencies
Seattle & the Puget Sound Region
Water intrusion and exterior envelope failures in HOA and multi-family buildings require fast, coordinated, and experienced response. Active leaks, flashing failures, or inspection-triggered findings can affect multiple units at once and escalate quickly if not addressed correctly.
Synapse Construction provides emergency building envelope repair services for HOAs, condominiums, and multi-family properties throughout Seattle and the greater Puget Sound region. We specialize in diagnosing complex exterior failures and implementing targeted, code-compliant repairs that stabilize buildings and protect residents.
What’s Happening
In multi-unit buildings, water intrusion often originates at shared exterior systems and migrates horizontally or vertically before becoming visible inside units.
Common triggers for emergency calls include:
- Active leaks affecting multiple units
- Water intrusion discovered during special inspections
- Flashing or waterproofing failures at roofs, decks, or window assemblies
- Siding or cladding failures exposing wall assemblies
- Sudden moisture issues following heavy rain or wind events
Because systems are interconnected, the visible damage is often only part of the problem.
Why Building Envelope Emergencies Are Urgent
Exterior failures in multi-family buildings can quickly expand in scope if not addressed promptly.
Delaying response can result in:
- Widespread concealed rot and structural damage
- Mold growth and indoor air quality concerns
- Damage spreading across units and elevations
- Increased liability exposure for HOAs and boards
- Escalating repair costs and resident disruption
Early stabilization and investigation help control both risk and cost.
How Synapse Construction Responds to HOA Emergencies
Our emergency response focuses on stabilizing the building, identifying root causes, and providing clear repair paths.
Our process typically includes:
- Exterior and interior evaluation of affected areas
- Identification of water paths across assemblies
- Selective removal of cladding or finishes to confirm conditions
- Temporary or permanent stabilization measures as needed
- Documentation of findings with photos and clear explanations
- Coordination with HOA boards, property managers, and consultants
We understand the communication, documentation, and decision-making requirements unique to HOA and multi-family environments.
Common Multi-Family Envelope Failures We Address
During emergency response and repairs, we frequently encounter:
- Failed or missing flashing at roof-to-wall transitions
- Water intrusion at deck and balcony assemblies
- Aging or improperly installed siding and cladding systems
- Window and door assemblies lacking proper integration
- Waterproofing failures affecting stacked units
Many of these issues are concealed until active leaks occur.
