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

We’ve been part of the Garrison Partners family since 2004, and our Apopka customers know what that track record means: we show up when we said we would, in uniform, with background-checked technicians who’ve already been introduced by name. Our 365-Day Done Right Promise covers every duct sealing job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a verbal assurance you hope someone remembers. It’s on the paperwork.

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 to get on the schedule. When you’re dealing with musty air or a system that can’t keep up with Apopka’s humidity, that responsiveness matters.

We price every job in writing before any work starts. The number doesn’t move at the door. Our crews use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we explain what we’re doing in plain terms while we’re doing it. The Garrison Code requires it.

Duct Repair in Apopka

Duct Repair in Apopka often starts with a homeowner noticing one room won’t cool, or the utility bill has climbed without explanation. In this market, the culprit is frequently decades-old flex duct that’s been abraded by sand from Lake Apopka’s sandy soil, or original galvanized runs in pre-1980s homes that have developed pinhole leaks and separated joints. We inspect with camera equipment, identify the damage, and quote the repair in writing before touching anything. A typical duct repair in Apopka runs $280 – $520 depending on accessibility and the extent of the damage.

Disconnected and Crushed Runs

We find crushed return trunks more often than you’d expect, especially in homes where ductwork was installed before modern load calculations. A crushed run doesn’t just reduce airflow; it creates negative pressure that pulls unconditioned attic air into the system. We rebuild or replace the damaged section, then seal all connections with mastic and mesh so the repair holds.

Pinhole Leaks in Metal Duct

Original galvanized duct in older Apopka homes near downtown develops pinholes from the inside out, accelerated by humidity and the slight acidity of condensate. Spot repair with mastic and reinforcement tape works for limited damage; more extensive deterioration means section replacement. We tell you which we’re recommending and why.

Air Duct Sealing in Apopka

Air Duct Sealing in Apopka is frequently the necessary follow-up to cleaning, especially in homes where sandy grit from the lake area has worn at flex duct seams for years. Sealing addresses the leaks that let conditioned air escape into the attic and unconditioned humid air get pulled into your living space. We use mastic, mesh reinforcement, and mechanical fasteners at every joint and penetration. A typical whole-system air duct sealing job in Apopka runs $480 – $890 for an average single-family home, with larger or more complex systems toward the upper end.

Mastic Sealing Versus Tape Alone

Foil tape fails in Florida attics. The adhesive degrades in heat, and the tape peels. We use water-based duct mastic, brushed or sprayed onto every seam, then reinforced with mesh at high-stress joints. It stays flexible, it bonds to metal and flex duct, and it doesn’t off-gas the way some solvent-based products do.

Sealing After Grit Damage

When sand from Lake Apopka’s soil has abraded flex duct connections near the air handler, cleaning alone won’t stop the leaks. We identify the worn sections, repair or replace as needed, then seal the entire system to prevent the same pattern from recurring. The goal is a sealed system that maintains static pressure where the designer intended it.

Trusted Brands We Service in Apopka

Our Apopka crews carry equipment and materials from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell, Aprilaire, and Guardsman. That means no waiting on parts for standard sealing and repair jobs. When we quote a job, we’re quoting with the actual materials we’ll use, not a generic placeholder that changes once we’re in your attic. For Apopka homeowners, that translates to faster turnaround and fewer return visits. We explain the equipment we’re using and what it does for your specific system, because The Garrison Standard requires that you understand what you’re paying for before you pay it.

Common Duct Sealing Problems We See in Apopka Homes

• Sandy grit abrading flex duct seams. Apopka’s sandy soil and proximity to Lake Apopka mean fine particles get drawn into outdoor units and circulated through duct runs. Over years, this grit wears through flex duct outer layers and loosens connections near the air handler. Standard cleaning removes the debris; sealing repairs the damage it caused.
• Original galvanized ducts with pinhole leaks. Homes built before the 1980s, common near downtown Apopka and around older lakefront properties, often have metal ductwork that has corroded from the inside. Humid attic air accelerates the process. We spot-seal where possible and recommend section replacement where the metal is too far gone.
• Disconnected joints in multi-turn flex runs. Newer homes in Wekiva and Wolf Lake sometimes use flexible duct with tight radius turns that stress connections. Thermal expansion and contraction in Florida’s heat cycles loosen these joints over time. We reseat and seal every connection we can access.
• Musty odor from organic matter near the lake. Homes within a few miles of Lake Apopka often show a distinct musty grit in ductwork, a combination of sand and decaying organic material. Cleaning removes it; sealing prevents reintroduction by eliminating the negative pressure that pulls attic and crawl space air into the system.
