That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Duct sealing in Imperial Beach typically runs $450 – $1,200 for a whole-home system, and most jobs are scheduled within a few days of your call.

We’ve worked on enough homes from Seacoast Drive to the east side of Palm Avenue to know that Imperial Beach duct systems aren’t fighting the same battle as inland San Diego. The marine layer here doesn’t just make mornings gray, it keeps humidity locked inside attics and crawlspaces where salt-laden air finds every gap in your ductwork. Our Duct Sealing team serves Imperial Beach from our San Diego dispatch office, with crews who understand coastal corrosion and the older housing stock that dominates this market.
Why Hollis Air Duct Cleaning Is Imperial Beach’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our track record predates most competitors you’ll find in the 91932 ZIP code. That longevity matters because duct sealing done wrong in Imperial Beach fails fast, the salt air sees to that. Our 365-Day Done Right Promise covers every repair in writing for a full year, if the work fails, Hollis comes back at no charge, including a free second visit.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. The price is written down before any tool touches your system, and it does not move at the door. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops, no callback queues.

Roy Castellanos leads our operation, and The Garrison Standard he works under means arriving squared away, pricing in writing, completing the job by the book, and leaving the site clean. That’s not marketing language, it’s how we account for every minute in a customer’s home.
Duct Repair in Imperial Beach
Duct Repair in Imperial Beach means fixing the physical damage that salt air, sand intrusion, and decades of coastal humidity inflict on metal ductwork. We see pitted galvanized trunks, separated joints where mastic has dried and cracked, and return-air boots packed with fine beach sand that accelerates corrosion from the inside out. A typical duct repair in Imperial Beach runs $280 – $650 depending on accessibility and the extent of metal replacement needed.
When Repair Beats Replacement
Not every corroded section needs tearing out. If the pitting is surface-level and the structural integrity holds, we can clean the metal, treat the corrosion, and seal the joint with proper mastic and reinforcement. This saves Imperial Beach homeowners money and preserves the original duct sizing, which matters in older beach cottages where modern retrofits rarely fit cleanly.
Salt-Air Damage Assessment
We run camera inspection before quoting any duct repair. You see what we see, pitted metal, sand accumulation, or moisture staining at the joints. Then we write the price. No surprises after we start cutting.
Air Duct Sealing in Imperial Beach
Air Duct Sealing in Imperial Beach addresses the gaps, cracks, and failed joints that let unconditioned attic and crawlspace air mix with your supply air. In a coastal environment, this isn’t just an efficiency problem, it’s how salt-laden, humid air enters your living space and accelerates corrosion inside the duct runs. A typical air duct sealing job in Imperial Beach runs $450 – $1,200 for a whole-home system, with smaller condo jobs at the lower end and multi-zone bungalow systems toward the top.
Mastic Sealing for Coastal Conditions
We use duct sealing matic, a fibrous paste that flexes with temperature swings and bonds to metal even where surface corrosion has begun. Tape alone fails in Imperial Beach’s humidity; mastic is the standard we apply on every job, brushed into joints and reinforced with mesh where gaps exceed standard tolerances.
Pressure Testing After the Seal
After sealing, we pressure-test the system to verify leakage reduction. You get the before and after numbers in writing. If the seal doesn’t hold, we find why and fix it before we leave. That’s The Garrison Standard.
Trusted Brands We Service in Imperial Beach
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris removal, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. We stock common sealing materials and replacement boots locally, so Imperial Beach customers aren’t waiting on parts shipments while salt air continues eating their ductwork. When a return-air boot on a Seacoast Drive condo needs replacing, we measure, cut, and seal without a second trip.
Common Duct Sealing Problems We See in Imperial Beach Homes
- Salt-corroded joints that re-leak after quick fixes. Sealing over wet, corroded metal without addressing the moisture source first means the mastic lifts within a season and rust keeps spreading underneath. We clean and treat the metal before any sealant goes on.
- Sand-packed return boots causing abrasion damage. On the west side of Imperial Beach, fine beach sand infiltrates return-air registers and packs into boots, grinding against metal surfaces and creating leak paths that standard sealing misses. We source-remove the sand before sealing, or the seal traps abrasive material inside.
- Fogging “sanitiser” upsells that don’t solve the real problem. Some outfits spray a chemical fog and call the ducts clean. That doesn’t remove microbial growth from duct linings or stop salt air from entering through open joints. We do source removal under negative pressure to NADCA standards, then seal the pathways.
- Short duct runs with multiple failure points. Imperial Beach’s compact beach cottages and 1970s condos often have abbreviated duct systems where one failed joint affects the whole run disproportionately. We map the system before quoting so you know exactly which joints need attention.
Pricing for Duct Sealing in Imperial Beach, CA
A typical whole-home duct sealing in Imperial Beach runs $450 – $1,200. Condos and smaller bungalows with single-zone systems usually fall in the $450 – $700 range. Larger homes or systems with extensive corrosion remediation can reach $900 – $1,200. Duct repair, when needed before sealing, adds $280 – $650 depending on metal replacement and accessibility.
What moves the price: the number of joints requiring sealant, whether boots or trunks need replacement first, attic versus crawlspace access, and the extent of sand removal needed before sealing can begin. We inspect with a camera, write the price, and get your approval before starting. One flat price per system, agreed before work starts, no per-vent add-ons, no equipment fees at the door.

FAQs About Duct Sealing in Imperial Beach
Look for rust staining around registers, musty odors when the system runs, or visible pitting on metal boots and trunks in accessible areas. In Imperial Beach, corrosion often concentrates on west-facing duct runs and return-air boots where onshore winds deliver the most salt spray. If you see these signs, call (361) 326-5060 for a camera inspection, we’ll show you exactly what condition your metal is in.
We work across all of Imperial Beach, from the beachfront condos along Seacoast Drive to the residential streets east of Palm Avenue and the areas near the Tijuana River Valley. Our San Diego dispatch gets crews to Imperial Beach properties on schedule, whether it’s a 1960s bungalow or a 1980s condo complex.
We do not promise same-day dispatch, duct sealing is a scheduled job that requires proper inspection and preparation. Our phones are answered by a live person 24/7, and we prioritize urgent situations like separated trunk lines or major leaks that are actively dumping unconditioned air into your home. Call (361) 326-5060 to discuss timing.
It can be, because coastal jobs often require sand removal and corrosion treatment before sealing can begin. The $450 – $1,200 range for Imperial Beach reflects this additional prep work. Inland communities without salt-air exposure may see simpler jobs at the lower end of comparable ranges, but they also don’t face the accelerated failure rates we see near the ocean.
Every duct sealing job is covered in writing for one full year. If a sealed joint fails, if corrosion we treated redevelops under our sealant, or if the leakage reduction doesn’t hold, Hollis returns and makes it right at no charge. This includes a free second visit, not a discounted callback. The promise is backed by Roy Castellanos and the Garrison Partners family, not a faceless corporate policy.
