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.
Fast, Reliable Duct Repair & Sealing Across Cleveland
Duct repair and sealing in Cleveland typically runs $280-$650 for most residential jobs, with flex duct replacement in flood-affected homes climbing toward the upper end when mold remediation is involved. We dispatch crews to Cleveland from our Houston coordination office, and we’re familiar with the specific conditions that degrade ductwork in Liberty County’s Piney Woods - the sustained humidity, the post-Harvey flood legacy, and the pollen loads that clog systems faster than you’ll see in drier parts of Texas. Call (346) 248-1474 for a written estimate before any work begins.
Our Duct Repair & Sealing team has worked the streets feeding off US-59 and East Houston Street enough to know what we’re pulling back when we open an attic hatch. Cleveland’s housing stock - heavy on 1970s-1990s ranch homes and manufactured housing with vented-attic flex duct - degrades differently than the slab-duct systems common further west. The humidity here doesn’t let up. Even in October, your attic is a steam bath, and every time the AC cycles off, condensation forms inside those flex runs. That’s not a theory. We photograph it.
Why CleanRun Air Duct Cleaning The Woodlands Is Cleveland’s Preferred Duct Repair & Sealing Company
We’ve served Cleveland since adding Liberty County to our route schedule, and the pattern is consistent: homeowners who bought after 2017 often don’t know which duct sections were actually replaced after Harvey versus which were merely dried and closed back up. Our camera inspection finds the difference. Tomas Reyes established CleanRun in 2013 on the principle that every customer receives a written price before work starts, a documented photo record of every duct run, and a 365-Day Done Right Promise backed in writing - Haven Standard Clause 1, Clause 4, and Clause 6. No manager approval required.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. The equipment we bring to Cleveland jobs includes Rotobrush and Nikro systems for source removal, plus Honeywell and Aprilaire components for sealing and air quality work. Customers can verify each brand independently. We don’t use shop-vac noise and call it done.
Scheduling is coordinated from our Houston office, but the crew that arrives at your Cleveland property knows the local conditions: which neighborhoods near Stancil Park sit low enough to have taken water, where the 77327 ZIP code boundaries shift between older ranch construction and newer builds, and why a musty odor when the AC cycles off almost always means hidden moisture in a flex section that was “remediated” years ago but never properly inspected.
Our Duct Repair & Sealing Services in Cleveland

Flex Duct Repair
Cleveland’s housing stock runs heavy on flexible ductwork in vented attics - the standard for 1970s-1990s ranch homes and most manufactured housing in Liberty County. That flex duct degrades fast here. The outer insulation jacket cracks from sustained attic heat. The inner liner tears at elbows and supports. And in flood-affected homes, the inner lining can harbor mold film that no surface cleaning reaches.
We were called to a 1980s ranch on East Houston Street where the homeowner reported a musty odor whenever the AC cycled off. Using camera inspection, we pulled back a flex run and found the inner lining coated with a dark film left by Harvey-era flood moisture - untouched despite a partial replacement years earlier. We performed source removal under negative pressure, rebuilt the joint with mastic sealant and new flex duct, then sealed the air handler connection to stop humid attic air from re-entering. The photo record showed the customer exactly what was removed and what was installed.
Typical flex duct repair in Cleveland runs $180-$340 per run, with full replacement of flood-compromised sections ranging $280-$520 depending on length and attic access.

Mastic Sealant Application
Duct tape fails. In Cleveland’s humidity, it fails faster. The adhesive degrades, the tape peels, and suddenly you’re cooling your attic instead of your living room. Mastic sealant - a thick, fiber-reinforced compound brushed onto joints and seams - is the only sealing method that holds up in Southeast Texas conditions.
We apply mastic to every accessible joint after repair or cleaning work. In older Cleveland homes with original metal duct systems, we often find previous owners tried to seal leaks with successive layers of tape, each one failing and trapping moisture against the metal. We strip that back, clean the surface, and apply a proper mastic bed. The result is measurable: we pressure-test before and after, and the customer sees the numbers in writing.
Mastic sealing work in Cleveland typically ranges $220-$480 for a full system, depending on duct accessibility and the extent of previous failed repairs.

Duct Insulation
Uninsulated or degraded duct insulation in a Cleveland attic is like running cold water through a warm pipe - condensation forms, mold follows, and your energy bills climb while your comfort drops. In manufactured homes and older ranches throughout the 77327 area, we regularly find insulation that’s compressed, moisture-stained, or simply missing where critters or previous work disturbed it.
We install proper insulation barriers around repaired or replaced duct sections, using materials rated for the humidity and temperature swings of Southeast Texas attics. This isn’t the thin foil wrap that comes loose in six months. We photograph the before condition, the installation process, and the finished work - part of the standard Documented Photo Record on every visit.
Duct insulation work in Cleveland generally runs $260-$580 for partial system work, with full attic duct insulation reaching $740-$1,200 in larger homes.

Metal Duct Repair
Some Cleveland homes, particularly pre-1980 builds near Stancil Park and the older sections along East Houston Street, still have galvanized steel ductwork. When it’s intact, it’s durable. When it’s corroded at seams or crushed from attic traffic, it needs sectional replacement or spot repair with proper mechanical fastening and mastic sealing. We don’t patch metal with tape. We cut, fit, fasten, and seal - then photograph the joint for the job record.
Metal duct repair in Cleveland typically ranges $240-$560 depending on accessibility and whether sections need custom fabrication.

AfterTrusted Brands We Service in Cleveland
CleanRun technicians arrive with professional-grade equipment from trade-recognized brands: Rotobrush and Nikro for source removal and mechanical cleaning, Honeywell controls and sensors for system diagnostics, and Aprilaire media and sealing products for air quality work. We stock common flex duct diameters, mastic compounds, and insulation materials for Cleveland jobs, which means most repairs don’t wait on parts orders. If your system uses specific manufacturer components, we’ll identify them during inspection and source matching parts when needed. Every brand named here can be verified independently - we don’t make performance claims beyond what the manufacturers publish.
Common Duct Repair & Sealing Problems We See in Cleveland Homes

- Harvey-era flood moisture still trapped in flex duct sections. We regularly pull back flex runs in homes along streets feeding off US-59 and find dark, musty biological film inside - even when owners believe remediation was completed years ago. Partial replacements after 2017 often left adjacent sections untouched, and those sections kept growing mold in the humid attic environment.
- Condensation cycling inside attic ducts every time the AC shuts off. Cleveland’s humidity routinely exceeds 85% even outside summer. When cold air stops flowing, warm moist attic air hits the duct surface and water forms. Daily. This feeds mold growth that’s far more aggressive than in Central or West Texas markets, and it degrades flex duct liners from the inside out.
- Pine and oak pollen clogging return pathways and coating interior duct surfaces. The surrounding Piney Woods produce pollen loads that overwhelm standard filtration and build up rapidly on duct walls. That buildup traps moisture, accelerates tape and mastic failure, and restricts airflow until the system strains itself toward breakdown.
- Failed duct tape repairs from previous service visits. We find this everywhere in Cleveland’s older housing stock: silver tape peeling at joints, adhesive turned to powder, air leaking into attics for years. Each failed repair made the system work harder and the homeowner pay more. We strip it all and apply proper mastic - once, documented, guaranteed.

FAQs - Duct Repair & Sealing in Cleveland

For Cleveland properties in the Piney Woods, we recommend duct cleaning every 2-3 years - shorter than the 4-5 year interval typical in drier Texas markets. The combination of 85%+ humidity, heavy pine and oak pollen, and post-Harvey flood legacy means biological buildup and debris accumulation happen faster here. Homes on unpaved roads or with outbuilding HVAC systems may need more frequent attention due to dust loading. Rural properties with wood heat as supplemental or primary heating should also inspect annually for creosote and particulate deposits in ductwork. Call (346) 248-1474 to schedule a camera inspection and we’ll show you exactly what’s inside your system.
Yes, and this is specifically what we encounter in Cleveland. We don’t clean flood-damaged flex duct - we replace compromised sections, then seal and insulate the connections properly. The field vignette from our East Houston Street job is typical: camera inspection reveals dark mold film inside flex that was “remediated” years ago but never actually removed. We document the condition, quote replacement in writing, and perform source removal under negative pressure before installing new flex with mastic-sealed joints. The 365-Day Done Right Promise covers our repair work. Call (346) 248-1474 for a free second opinion if you’ve been told your ducts are fine but you still smell must when the AC cycles off.
Duct sealing closes the gaps and leaks where conditioned air escapes into your attic or crawl space - and where unconditioned, humid air gets pulled back in. In older Cleveland homes with original metal duct or aging flex systems, we typically find 15-25% air loss at joints, seams, and previous repair points. We seal with mastic compound, not tape, after cleaning and repairing any damaged sections. The result is lower energy bills, more even temperatures room-to-room, and reduced humidity infiltration that otherwise feeds mold growth. We pressure-test before and after, and you receive the numbers in your written job record. Call (346) 248-1474 for an estimate.
Yes. Many Cleveland-area properties have workshop HVAC, barn cooling systems, or guest cottage ductwork that needs the same attention as the main house. We inspect and repair these systems with the same documented photo record and written pricing. Access and component sizing vary more in outbuildings, so we quote each job individually after inspection - never over the phone. Rural properties may have longer service drives, which we account for in scheduling but not with hidden add-ons. The price you approve in writing is the price you pay. Call (346) 248-1474 to discuss your outbuilding system.
Cleaning removes debris and biological buildup from accessible duct surfaces. Repair and sealing fix the physical damage and air leaks that caused the problem or prevent proper system function. In Cleveland, you need repair or sealing when: you smell must or mildew specifically when the AC cycles off (indicating moisture intrusion at a leak point); some rooms stay hot while others overcool (air loss at a disconnected or crushed run); your energy bills spike without usage changes (conditioned air escaping to attic); or you can see duct tape peeling at joints or insulation hanging loose. Camera inspection distinguishes cleaning needs from repair needs - we don’t sell you cleaning when your ducts are physically compromised. Call (346) 248-1474 and we’ll show you what the camera sees.
