We’re David Martinez and the crew at Liberty Bell Air Duct Cleaning Greater Cleveland, and we’ve spent 17 years crawling through the exact duct systems that dominate this city — the long basement trunk lines and hidden angle drops of 1960s–1980s homes that most HVAC generalists never touch. From the wooded lots off Sprague Road to the hillside neighborhoods near the Brecksville border, we carry professional-grade equipment including Rotobrush and Abatement Technologies systems so we can seal, repair, and insulate your ducts in a single trip.

Why Liberty Bell Air Duct Cleaning Greater Cleveland Is Broadview Heights’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Broadview Heights one crawlspace at a time. Our 501 verified reviews average 4.7 stars, and a solid chunk of those come from homeowners in the 44147 zip code who’ve watched David personally lead their Duct Repair & Sealing job from start to finish — not hand it off to a rotating crew.
Here’s what that means in practice: when you call us for a split-level off Wallings Road or a raised-ranch near the Broadview Heights Community Center, David shows up with the tools, assesses your system himself, and stays until the work is done. No dispatchers, no subcontractors, no “the other guy will finish tomorrow.” Seventeen years in this single trade means we’ve seen every failure mode these homes throw at us — failed flex duct in crawlspaces, mastic that’s cracked from decades of furnace cycling, attic crossover runs bleeding heat into unconditioned space.
Our response time to Broadview Heights averages under 60 minutes because we’re based in Greater Cleveland and know these roads cold. We’ve worked on enough homes backing up to the wooded eastern corridors to know which basements flood in spring thaw, which attic hatches are too small for standard equipment, and where the original 1970s sheet metal has started separating at the seams. That local knowledge saves you time and money.
Our Duct Repair & Sealing Services in Broadview Heights
Duct Sealing with Mastic Sealant
Broadview Heights’s prolonged heating season — five-plus months of near-continuous furnace operation — pounds duct joints with thermal expansion and contraction until they leak. We use professional-grade mastic sealant, not the duct tape you’ll find at hardware stores, because Northeast Ohio humidity destroys tape adhesive within a year. On a typical split-level near Wallings Road, we’ll seal 40–60 linear feet of trunk line and all branch connections, stopping the energy loss that’s been pulling unconditioned crawlspace air into your system for decades.
Flex Duct Repair
The flex duct serving those half-story upper floors in 1970s Broadview Heights split-levels is often original, crushed, or rodent-damaged. We replace collapsed sections with new insulated flex duct rated for the temperature swings these homes see, and we secure it properly so it doesn’t sag back into the same kinked configuration within a year. In homes backing wooded lots — common throughout the eastern residential corridors — we’ve found squirrel and raccoon damage in attic flex runs that homeowners never knew existed until we traced the airflow loss.
Metal Duct Repair
Those long sheet-metal trunk lines beneath Broadview Heights living floors? They’re built to last, but after 40–60 years the longitudinal seams start separating and the takeoff collars loosen. We re-seam corroded sections, replace rusted fittings, and reinforce connections so your furnace isn’t blowing heated air into the basement instead of the bedrooms. Metal repair on a typical ranch home in the 44147 area runs $180–$340 per section, depending on accessibility.
Duct Insulation
Uninsulated or degraded duct insulation is a hidden energy thief in Broadview Heights raised-ranch designs, where attic crossover runs bleed conditioned air through unheated spaces. We install new fiberglass duct wrap or replace damaged insulation on flex runs, bringing your system up to current efficiency standards. This matters especially in homes with original 1960s–1970s construction where insulation has compressed, torn, or absorbed moisture from humid summers.

Trusted Brands We Service in Broadview Heights
We work with and stock parts from leading air-quality brands including Aprilaire, Abatement Technologies, and Guardsman — names that hold up in the demanding Northeast Ohio climate. For Broadview Heights homeowners, that means faster turnaround: when we find a failed component during your duct sealing job, we’re not ordering parts from Cleveland and rescheduling. We’ve got the mastic, insulation, and replacement fittings on the truck, so your 1970s split-level on Sprague Road gets finished same-day, not stretched across two visits.
Common Duct Repair & Sealing Problems We See in Broadview Heights Homes
- DIY-sealed visible runs with hidden angle drops ignored. Homeowners in Broadview Heights often seal what they can reach in the basement while the short, angled drops serving half-story upper floors — standard in 1970s split-levels — remain untouched. Those hidden branches concentrate mold and debris, especially in homes backing wooded lots where humidity runs higher.
- Standard duct tape failure on metal trunk lines. We regularly find basements in Broadview Heights where someone used hardware-store duct tape on sheet-metal seams. The adhesive fails within 12 months of Northeast Ohio humidity cycles, and the leaks return worse than before as the tape residue prevents proper re-sealing.
- Uninsulated attic crossover runs in raised-ranch designs. These homes pump heated air through unconditioned attic space all winter, wasting 20–30% of furnace output. The original insulation, if it existed at all, has often fallen away or been disturbed by prior work.
- Original flex duct crushed or kinked from decades of compression. In the tight crawlspaces and half-story chases of Broadview Heights’s 1960s–1980s housing stock, flex duct gets flattened by storage items, foot traffic during other repairs, or simply gravity over time. The airflow restriction shows up as cold rooms and high energy bills.
Pricing for Duct Repair & Sealing in Broadview Heights, OH
Here’s what duct repair and sealing costs in the Broadview Heights market, based on the size and complexity of the homes we typically service:
| Service | Typical Range in Broadview Heights |
|---|---|
| Basic duct sealing (mastic, accessible trunk lines) | $280–$420 |
| Full-system sealing including hidden angle drops | $480–$680 |
| Flex duct repair/replacement (per run) | $150–$290 |
| Metal duct section repair or replacement | $180–$340 |
| Duct insulation (attic crossover or crawlspace run) | $200–$380 |
What moves you up or down within these ranges: accessibility (crawlspace height, attic hatch size), linear footage of ductwork, whether we need to remove old failed sealant first, and how many hidden angle drops your split-level contains. The 1970s homes with multiple half-story branches take longer — there’s no way around it — but we quote upfront after inspection, not after we’ve started. Estimates are free. Call (877) 516-9047 to schedule.

FAQs — Duct Repair & Sealing in Broadview Heights
The 1970s split-levels common in Broadview Heights have more linear duct footage per home than typical ranches, with long basement trunk lines feeding multiple 90-degree turns and short angle drops to half-story floors. Those hidden angle drops were often poorly sealed originally and have never been serviced, so they leak continuously into wall cavities and unconditioned spaces. We see this on nearly every split-level we inspect in the 44147 area — call (877) 516-9047 and we’ll show you exactly where your system is bleeding air.
A full sealing on a raised-ranch or ranch in Broadview Heights takes 4–6 hours for accessible basement trunk lines, or 1–2 days if we’re also addressing attic crossovers and hidden angle drops in a split-level. We don’t rush the mastic curing time — it needs to set properly in our humid summers and cold winters. David will give you a specific time estimate after inspecting your layout; estimates are free at (877) 516-9047.
If the flex duct is crushed, torn, or more than 25 years old, we recommend replacement before sealing — patching degraded material is a short-term fix that fails within a season or two. For newer flex with minor damage, we can repair sections and integrate them into the sealed system. We’ll show you the condition during our free inspection and give you both options with exact pricing.
We use professional-grade mastic sealants compatible with Abatement Technologies application standards — the same products specified for commercial IAQ work, not consumer-grade caulk. For insulation, we source materials that hold up to the Lake Erie snow-belt temperature swings your Broadview Heights home experiences. The brands are on our truck; we’re not making a supply run while your basement sits open.
For most Broadview Heights homes with accessible basement trunk lines, we seal from the outside — it’s more thorough and lets us inspect every joint visually. For hidden angle drops and tight chases in split-level half-stories, we sometimes use aerosol-based internal sealing as a supplement, but we prefer physical mastic application where we can reach. We’ll recommend the right approach after seeing your specific layout; call (877) 516-9047 to schedule a look.
