Spray Foam Attic & Dewpoint Trap
Remediation in Stuart, FL

Along the St. Lucie River, high ambient humidity clashes with modern sealed spray foam roof decks. When oversized air conditioners short-cycle, unvented attics trap moisture at the dew point, breeding invisible wood-destroying fungi behind insulation layers.

The Sealed Attic Dilemma on the Treasure Coast

Spray foam insulation is popular in Martin County waterfront homes (such as Sewall’s Point, Rocky Point, and Stuart Yacht & Country Club) for its energy efficiency. However, sealing an attic creates a semi-conditioned space with distinct psychrometric vulnerabilities:

Why Riverfront Foam Attics Fail:
  • HVAC Short-Cycling: Oversized AC units satisfy sensible heat quickly and shut off before dehumidifying. Moisture builds up in the attic airspace, pushing relative humidity past 70%.
  • Dew Point Condensation at the Deck: When warm river humidity penetrates microscopic roof gaps, it meets the chilled air-conditioned attic envelope, condensing on the underside of roof sheathing.
  • Hidden Structural Wood Rot: Because the foam covers the trusses, wood rot and toxic mold colonies flourish out of sight until musty smells permeate ceiling drywall.

Our Martin County Attic Decontamination System

Engineering protocols directed by President Enrique J. Muniz (MRSR 2425).

1. Psychrometric Mapping

We calculate vapor pressure differentials, dew point thresholds, and equilibrium moisture content across your roof deck framing.

2. Surgical Foam Extraction

Only compromised foam sections are surgically excised under HEPA negative containment, preserving undamaged insulation.

3. Sani-Shield Polymer

Exposed roof deck timbers are micro-cleaned and coated with our antimicrobial fungistatic polymer to permanently repel moisture.

4. AIHA Lab Clearance

Third-party accredited laboratory testing certifies zero fungal elevation before project sign-off and warranty issuance.

Martin County Homeowners FAQ

Frequently Asked Questions

When an attic is sealed with spray foam, it becomes part of the home's conditioned envelope. If your HVAC system is oversized, it cools down the house too quickly without running long enough to remove moisture (short-cycling). The humid riverfront air reaches its dew point, condensing on roof sheathing hidden directly behind or within the foam.

Not necessarily. We utilize precision thermal imaging and deep pin moisture probes to locate exact moisture pockets. In many cases, localized surgical remediation, thermodynamic air stabilization, and our Sani-Shield bio-treatment resolve the issue without a total tear-out.

We evaluate psychrometric balance, specify supplemental whole-home dehumidification where needed, and provide a 1-year transferrable Sani-Guarantee backed by independent laboratory clearance testing.
