Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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.

AfterFast, Reliable Duct Sealing Across Brunswick
Duct sealing in Brunswick typically costs $350 – $850 for a whole-house system, with most ranch homes falling in the $450 – $650 range depending on how much of the original galvanized steel ductwork needs attention. We’re familiar with the mid-century housing stock here, from the neighborhoods around historic downtown to the subdivisions off Pearl Road and Center Road, and we schedule Brunswick jobs - including our Dryer Vent Cleaning in Brunswick - with dispatch coordinated from our Cleveland office. If your upstairs bedrooms stay cold while your basement feels like a sauna in January, the problem is usually leaky or disconnected ducts, not your furnace. Call us at (361) 326-5060 and we’ll put a written price on the repair before any work starts.
Why Hollis Air Duct Cleaning Is Brunswick’s Preferred Duct Sealing Company
We’ve been working on Brunswick’s post-WWII ranches long enough to know what we’ll find before we open the basement door. The Garrison Standard means our technicians arrive inside the quoted window, uniformed and background-checked, with the job priced in writing before a tool comes out of the van. Our Duct Sealing team carries rotary brush systems from Rotobrush and negative-air equipment from Nikro, the same tools commercial crews use, because Brunswick’s aging galvanized steel demands it.
Our 365-Day Done Right Promise covers every sealing job in writing. If a joint we sealed opens up or a collar we reconnected fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround. Phones are answered by a live person 24 hours a day, 7 days a week, so you can schedule around your work week without waiting for a Monday callback.
We serve Brunswick and the surrounding Cuyahoga County metro area, and our crews understand how the local climate affects your system. Cold winters and humid summers mean your furnace and AC run hard year-round, pulling in pollen from the metro parks and summer mold spores that accelerate duct deterioration. That local knowledge changes how we approach the job.
Duct Insulation in Brunswick
Duct Insulation in Brunswick is most needed in the unconditioned basements and crawl spaces of the city’s 1950s-1970s ranch homes, where original galvanized steel runs lose heated and cooled air through thin metal walls before it ever reaches the vents. A typical duct insulation job in Brunswick runs $400 – $900, with costs climbing if we need to remove deteriorated old wrapping or access runs behind finished basement ceilings. We use professional-grade materials from Honeywell and Aprilaire, measured and cut to fit your existing trunks without the compression gaps that reduce R-value.
When Insulation Beats Sealing Alone
Some Brunswick homeowners call us for sealing when the real problem is uninsulated supply ducts running through a 55-degree basement. The metal sweats in summer, grows condensation mold, and bleeds heat in winter. If your ducts are structurally sound but the air arrives lukewarm at the register, insulation is the fix, not mastic. We’ll tell you straight after the camera inspection.
Basement Humidity and Duct Sweat
Brunswick’s summer humidity, fed by Lake Erie influence and the city’s low-lying areas near the interstate, pushes basement dew points high. Uninsulated cold-air returns sweat, rust from the outside in, and destroy their own sealant over time. We insulate with vapor-barrier-wrapped products that break that cycle.
HVAC Duct Sealing in Brunswick
HVAC Duct Sealing in Brunswick is rarely a simple tape-and-mastic job because of the city’s aging galvanized steel infrastructure. A standard whole-house sealing runs $350 – $850, but we often find that effective sealing requires reconnecting crushed branch runs and clearing rust scale first, which can add $200 – $400 to the scope. We put the system under negative pressure using Nikro equipment, verify airflow at each register with a digital manometer, and show you the before-and-after readings so you know the work mattered.
Chasing Leaks in Original Steel
The trunk joints and collar takeoffs in a 1962 Brunswick ranch have been expanding and contracting for sixty-plus years. Original duct tape is baked hard; early mastic is crumbly dust. We remove the failed material mechanically, prep the metal with HEPA-contained source removal, then apply new sealant that can actually bond to clean steel.
Disconnected Runs and Pressure Balance
Our camera inspections regularly find branch runs that have pulled free of the main trunk, often where a homeowner’s finished basement ceiling hides the damage. Sealing the accessible joints while ignoring a disconnected run is theater, not repair. We locate the break, reconnect with mechanical fasteners, then seal and test.
Trusted Brands We Service in Brunswick
We stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies for Brunswick jobs, which means no waiting on shipped-in specialty items when your 1959 furnace collar needs a custom transition. Our vans carry Nikro negative-air machines and Rotobrush rotary systems, and we source filtration upgrades from Guardsman when a sealing job reveals your system needs better protection against the pollen and mold spores that Brunswick’s climate pushes through the ducts. Fast turnaround matters when you’re losing heat to your basement in January, and keeping common parts on hand is how we honor the arrival window we quoted you.
Common Duct Sealing Problems We See in Brunswick Homes
- Original galvanized trunk joints have loosened after six decades of thermal cycling, and the duct tape or mastic applied in the 1970s is now hard, cracked, and leaking at every seam. We see this in nearly every pre-1980 ranch between Pearl Road and Center Road.
- Return ducts get crushed or disconnected under flooring in homes where basement ceilings were finished without regard to access. The living room register blows weakly while the basement stays comfortable because that’s where your heated air is going.
- Rust scale and debris inside old steel ductwork fouls any sealant bond. Patchwork sealing over an uncleaned system fails within a season. We use rotary agitation per NADCA standards to prep the surface before we seal.
- Collar takeoffs at the air handler have separated from vibration and poor original support, dumping conditioned air into the utility room or basement for years before a homeowner notices the pattern of cold rooms and high gas bills.
Pricing for Duct Sealing in Brunswick, OH
A typical whole-house duct sealing in Brunswick runs $350 – $850, with most mid-century ranches landing between $450 and $650. Factors that move the needle: how many original trunk joints need resealing, whether we find crushed or disconnected branch runs requiring reconnection, if the galvanized steel needs source removal before sealant will bond, and accessibility behind finished basement ceilings. We do not quote per-vent teaser prices that balloon once we’re inside. The price is written down before any work starts, and it does not move at the door. Estimates are free. Call (361) 326-5060 for an exact quote on your system.

FAQs About Duct Sealing in Brunswick
We can seal most original galvanized steel ductwork in Brunswick if the metal is structurally sound, which it usually is despite surface rust. The critical issue is whether the heat exchanger in your furnace has cracked, something we often find once the ducts are opened and inspected. If the exchanger is compromised, replacement is a safety issue, not an option. Call (361) 326-5060 and we’ll camera-inspect to give you a straight answer.
You almost certainly have a disconnected return duct or a major supply leak dumping heated air into the basement instead of the living spaces. This is the most common pattern we find in Brunswick’s full-basement ranches, especially where finished ceilings hide the ductwork. Sealing alone won’t fix it; we need to locate and reconnect the separated run first. Call (361) 326-5060 for a free inspection.
Yes. Brunswick’s galvanized steel trunks require mechanical prep and rotary cleaning before sealant application; flex ducting in newer suburbs is typically replaced entirely when it fails rather than sealed. Our tools and approach are specific to the metal infrastructure we find in mid-century ranches here. Call (361) 326-5060 to discuss your system.
We inspect the heat exchanger visually whenever we have the ductwork opened for sealing, and we flag cracks immediately because they present a carbon monoxide hazard. In Brunswick’s older neighborhoods near downtown, we find compromised exchangers often enough that we consider the inspection standard practice, not an upsell. If we find one, we’ll show you and explain your options before any additional work proceeds.
We measure static pressure and airflow at each register before and after the work, and we show you the numbers. In Brunswick’s older homes, we typically see static pressure drop 15 – 30% and airflow increase proportionally at previously weak registers. We also leave you with before-and-after photos of the sealed joints. If the improvement doesn’t hold, our 365-Day Done Right Promise means we return at no charge. Call (361) 326-5060 to schedule.
