Call (361) 326-5060

We’ve been driving to Sawgrass since long before the TPC Sawgrass clubhouse renovation made national news. We know the community’s back roads, the HOA notification requirements, and the particular headache of working in attics that hit 140°F by mid-July. When a homeowner near Sawgrass Country Club calls with a bedroom that never cools or a utility bill that jumped thirty percent, we don’t need a map. We need about forty-five minutes to arrive, a ladder, and a written price they’ll see before we touch anything.

Why Hollis Air Duct Cleaning Is Sawgrass’s Preferred Duct Sealing Company

Hollis Air Duct Cleaning, founded in 2004 as part of the Garrison Partners family, built its reputation in Northeast Florida by doing what we said we’d do and pricing it before we started. In Sawgrass, that means showing up inside the quoted window, not “sometime Tuesday.” Our technicians are background-checked, uniformed, and expected to follow The Garrison Code on every job: arrive squared away, price in writing, complete the work by the book, leave the site clean.

We don’t chase the lowest teaser price. We compete on discipline. Every duct sealing job in Sawgrass gets a written price before work begins and is covered by our 365-Day Done Right Promise. If the seal fails within a year, we return and make it right at no charge, including a free second visit. That promise is backed in writing on every job, not mentioned verbally and forgotten.

Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your AC is pumping conditioned air into the attic.

Duct Repair in Sawgrass

Duct Repair in Sawgrass usually means fixing flexible ductwork that has pulled loose at the collar, collapsed in a hot attic, or been chewed by rodents that found their way in through soffit gaps. Most Sawgrass homes built in the 1990s and 2000s use flexible duct running through unconditioned attic space, and that ductwork doesn’t age gracefully in our climate. We inspect with a camera, quote the repair in writing, and fix only what needs fixing. Typical duct repair in Sawgrass runs $350 – $950 depending on accessibility and the extent of damage.

Collapsed Flex Duct Sections

Attic temperatures in Sawgrass regularly exceed 130°F in July and August. Flexible duct sags over time, especially where support straps have failed, and a sagging duct can collapse completely. We replace the damaged section with new insulated flex duct, reinstall proper supports, and seal every joint with mastic.

Disconnected Return Collars

Return collars work loose from vibration and thermal cycling. A disconnected return pulls attic air straight into your system, along with fiberglass particles, dust, and whatever else is up there. We reattach with mechanical fasteners and sealed joints, then verify airflow at the register.

Air Duct Sealing in Sawgrass

Air Duct Sealing in Sawgrass addresses the leaks that develop where duct sections join, where flex duct meets metal boots, and where penetrations pass through drywall or framing. In a typical Sawgrass home, we measure 20 – 35% air loss through these gaps before sealing. After sealing with mastic and metal-backed tape, then pressure-testing with a duct blaster, we routinely see that loss drop below 5%. Whole-home air duct sealing in Sawgrass generally costs $1,200 – $1,800 for homes under 3,500 square feet, with larger homes or those needing extensive repair work reaching $2,000 – $2,400.

Mastic Sealing Versus Tape Alone

Hardware-store duct tape fails in attics. The adhesive degrades in heat, and the tape peels. We use water-based duct mastic, brushed on thick at every joint, plus metal-backed tape for mechanical reinforcement. Mastic remains flexible, fills irregular gaps, and lasts the life of the duct system.

Duct Blaster Verification

We don’t guess. After sealing, we pressurize the duct system and measure leakage with a duct blaster, the same tool energy auditors use for HERS ratings. You see the before and after numbers in writing. If the system doesn’t meet our standard, we keep working until it does.

Common Duct Sealing Problems We See in Sawgrass Homes

• Condensation-damaged tape at attic flex joints. Sawgrass attics cycle between extreme heat and cooler evening temperatures, especially during our daily summer thunderstorms. That temperature swing creates condensation on duct surfaces, and standard foil tape loses adhesion when wet. We find peeling tape at nearly every joint in homes over fifteen years old.
• Salt-air corrosion on metal trunk lines. The Atlantic is close enough that salt-laden air infiltrates attic vents and soffits. Over years, galvanized steel ductwork corrodes at seams and collars. We seal what we can and flag sections that need replacement before they fail completely.
• Post-hurricane mold forcing duct disassembly. After Hurricane Ian and the outages that followed, we handled dozens of calls from Sawgrass homeowners who returned to musty systems. Sealing alone doesn’t fix mold contamination, but proper sealing after cleaning prevents recontamination by eliminating the humid attic air that feeds it.
• HOA-mandated ceiling returns with poorly sealed drywall gaps. Many Sawgrass floor plans use ceiling-mounted return air grilles with drywall cutouts that are larger than the boot. The gap pulls attic air continuously. We seal these with code-compliant materials that satisfy both performance requirements and architectural review boards.
