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 Richmond Heights
Richmond Heights sits in the snow belt east of Cleveland, where lake-effect winters push furnaces hard for half the year and summers stay humid enough to make you notice every draft. If you’re watching utility bills climb while rooms stay stubbornly cold, your ductwork is likely bleeding conditioned air into the basement, crawlspace, or attic. We seal ducts for homeowners throughout Richmond Heights, from the post-war ranches along Highland Road to the split-levels near the Richmond Park area. Our crews dispatch from the Miami office and coordinate scheduling for Richmond Heights properties directly, with most jobs booked within a few days of your call. Reach us at (361) 326-5060 for a free written estimate.
Why Hollis Air Duct Cleaning Is Richmond Heights’s Preferred Duct Sealing Company
We’ve worked enough Richmond Heights homes to know the difference between a 1952 bungalow with original floor-joist return panning and a 1970s split-level with flex duct crammed above a drop ceiling. That matters because the sealing approach changes completely. Our Duct Sealing team uses mastic and professional-grade sealants, not tape that peels in damp basements. Homeowners here tell us they chose Hollis because we priced the job in writing before touching anything, and because our technicians arrived in uniform, on time, and inside the quoted window. The Garrison Standard requires it. Every repair carries our 365-Day Done Right Promise in writing. If the seal fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting through a callback queue while your furnace works overtime.
Air Duct Sealing in Richmond Heights
Air Duct Sealing in Richmond Heights means closing the gaps, seams, and disconnected joints in your forced-air system so the heat you pay for actually reaches your living spaces. Most homes here were built between 1940 and 1975 with galvanized rigid-metal duct or early flex duct that was never properly sealed at installation. Decades of thermal expansion, vibration, and rust have opened seams you can’t see but definitely pay for. A typical whole-system seal in Richmond Heights runs $850 – $1,800 depending on accessibility and how much of the system needs attention.
What We Seal and Why It Fails
We find the worst leaks at plenum connections, where the furnace meets the main trunk, and at register boots where ducts punch through walls or floors. In Richmond Heights’s older ranches, we regularly see return-air panning in floor joists that has separated from the wood, pulling basement air full of dust and concrete particulate into your breathing air. Our crews reach these with rotary brush systems and negative-air containment so nothing spreads through the house during the repair.
When Sealing Becomes Urgent
Call us when you notice hot rooms near the furnace and cold bedrooms at the far end of the house, or when your utility bill jumps without a rate increase. In Richmond Heights’s lake-effect climate, an unsealed system in January can cost you 30% more in gas than a tight one. We also recommend sealing before any new equipment installation. A high-efficiency furnace connected to leaky ducts is like pouring water into a cracked bucket.
Duct Sealing Services in Richmond Heights
Duct Sealing Services in Richmond Heights cover everything from spot repairs on accessible basement runs to full-system mastic sealing for homes with ductwork buried in soffits, crawlspaces, or finished ceilings. We don’t quote per-vent teaser prices that balloon once we’re inside. You get one flat price per system, agreed in writing before work starts, based on what we find during your free estimate. Most Richmond Heights jobs fall between $850 – $1,800 for complete sealing; partial repairs on accessible sections start around $400 – $650.
Our Sealing Process
We start with a visual inspection and, where needed, a pressure test to quantify leakage. Then we clean the surfaces, apply mastic sealant to every joint and seam, and reinforce high-stress areas with mesh and a second coat. For flex duct with torn outer liners, we sleeve and seal rather than replace when possible, saving you money. The work is documented with before-and-after photos of your own ducts, not stock images.
Equipment We Bring
Our vans carry Rotobrush rotary systems for pre-seal cleaning, Nikro negative-air machines for containment, and professional-grade mastic from Abatement Technologies and Guardsman. These are the same tools commercial crews use in hospitals and schools, not hardware-store tape and caulk. We explain what each piece does and why it matters for your specific layout before we start.

Trusted Brands We Service in Richmond Heights
Hollis stocks sealing products and filtration components from Honeywell, Aprilaire, Abatement Technologies, and Guardsman, so most Richmond Heights jobs need no special-order delays. If your system includes an Aprilaire media filter or a Honeywell electronic air cleaner, we can assess whether it’s seated properly and sealed to the ductwork, since a gap there bypasses filtration entirely. We also carry replacement boots and collars for the rigid-metal trunk lines common in Richmond Heights’s mid-century housing stock. Parts on the van mean we finish in one visit rather than leaving you with a half-sealed system while we wait for a shipment.
Common Duct Sealing Problems We See in Richmond Heights Homes
- Separated floor-joist return panning. In the 1940s and 1950s ranches near Richmond Park, builders nailed sheet metal directly to floor joists to create return channels. After 70 years of seasonal expansion, the nails back out and the gaps pull in basement air, dust, and occasionally moisture. We resecure and seal these with mastic and mechanical fasteners.
- Rusted plenum seams in damp basements. Richmond Heights’s older homes with stone or block foundations often have basement humidity that corrodes galvanized steel. We grind back rust, treat the metal, and seal with products rated for damp environments so the repair lasts.
- Disconnected flex duct in split-level additions. The 1960s and 1970s split-levels east of Highland Road often have flex duct run to later additions. The sag and weight of dust accumulation pulls connections apart at the boot. We support, clean, and reseal these runs properly.
- Unsealed register boots in exterior walls. Cold air from Richmond Heights’s winter wind washes leaks around boots in exterior walls, creating drafts and condensation stains. We seal the boot-to-wall and boot-to-floor connections and insulate where accessible.

Yes, we work the full Richmond Heights area including the ranches near Richmond Park, the split-level streets east of Highland Road, and the older cape-style homes closer to the city boundary. Each neighborhood’s duct configuration is different, and our crews know what to expect.
We do not advertise emergency dispatch for duct sealing because it is a scheduled repair, not an urgent safety issue. If your furnace has stopped working entirely, call an HVAC contractor first. Once the equipment is running, we can seal the ducts to make it efficient.
Richmond Heights pricing tracks close to other inner-ring Cleveland suburbs because the housing stock is similar: post-war construction with aging metal ductwork. Newer exurbs with modern flex-duct systems sometimes cost less to seal but need it less often. Your written estimate reflects your actual home, not your zip code.
Every duct sealing job is covered by our 365-Day Done Right Promise in writing. If any sealed joint fails within one year, Hollis returns and repairs it at no charge, including a free second visit. The guarantee is backed by the Garrison Partners family, not a third-party administrator. Call (361) 326-5060 with any concern and a live person will answer.
