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.

Why CleanRun Air Duct Cleaning Sugar Land Is Pearland’s Preferred Duct Repair & Sealing Company
We’ve worked inside Pearland duct systems since 2013, and the housing stock here is unmistakable: slab-foundation tract homes built between 2000 and 2018, almost all with flex duct routed through attics that hit 140°F for months each summer. That specific vintage matters. A crew that knows Pearland adjusts brush speed before entering a 2006 flex system. One that doesn’t learns the hard way when the liner crumbles.
Our reputation in Pearland is built on documentation, not claims. Every job starts with a written price under Haven Standard Clause 1. Every duct run is photographed before and after. The 365-Day Done Right Promise is backed in writing, not mentioned in passing. We’ve served more than 52,000 homes with this exact protocol.
Scheduling is coordinated from our Houston office, with crews routed to Pearland daily. You won’t get a call center in another state. You’ll get a background-checked, uniformed technician identified by name before arrival, operating under Haven Standard Clause 3: Verified Crews.
Our Duct Repair & Sealing team carries Rotobrush and Nikro equipment on every Pearland truck, plus the mastic and foil tape stock to seal boots and plenums on the spot without a return trip.
Our Duct Repair & Sealing Services in Pearland
Flex Duct Repair
Pearland’s master-planned subdivisions are saturated with flex duct now 15-25 years old. In Silverlake and Shadow Creek Ranch, we regularly open attic systems where the inner liner has turned so brittle from years of heat exposure that standard agitation tools risk shredding the material. Our crews start with low-speed brushing and visual inspection, then repair separated connections with mechanical fasteners and mastic sealant. When a run is too far gone, we replace it with new insulated flex, properly supported to prevent the sagging that caused the original failure. A typical flex duct repair or partial replacement in Pearland runs $180-$340 per run.
Duct Sealing
Sealing is where most Pearland homes see immediate return. Small breaches in supply and return ducts draw in humid Gulf Coast air 10-11 months a year, forcing your AC to dehumidify attic air instead of conditioned space. We seal boot connections, plenum joints, and chase penetrations with mastic sealant and foil tape - not the hardware-store duct tape that fails in months. A whole-system sealing job in Pearland typically ranges $280-$450, depending on access and the number of registers.
Metal Duct Repair
Older Pearland homes and some custom builds near the original town center still have galvanized metal ductwork. We repair separated seams, corroded sections, and failed dampers with sheet metal patches, S-cleats, and sealed rivets. Metal systems don’t suffer the liner fragmentation problem, but they leak at every joint if the original sealant has aged out. Repair costs for metal duct in Pearland generally fall between $220-$520.
Duct Insulation
When flex duct outer insulation has compressed or torn in a Pearland attic, the exposed liner becomes a condensation surface. We re-insulate damaged sections with formaldehyde-free duct wrap, sealed at all seams, or replace the run if the damage is extensive. Proper insulation also protects against the attic heat that accelerates liner degradation in the first place. Insulation work in Pearland typically adds $120-$280 to a sealing visit.
Air Leak Repair
Return-air leaks are especially common in Pearland’s slab homes, where the chase runs through wall cavities that were never properly sealed during construction. We pressurize the system, locate leaks with smoke or digital manometers, then seal with mastic or install access panels for repairs. Left unsealed, these leaks pull attic air, garage fumes, and post-Harvey moisture directly into your breathing air. Air leak repair in Pearland runs $200-$480 depending on chase access.

Common Duct Repair & Sealing Problems We See in Pearland Homes
- Brittle flex liner from attic heat. In 15-25-year-old Pearland systems, the inner liner hardens and cracks. Aggressive cleaning turns a $280 sealing job into a $1,200+ replacement. We inspect first, brush second.
- Post-Harvey moisture in return chases. The 2017 flooding drove water into duct cavities across wide swaths of Pearland. Latent mold on liner and coils won’t be fixed by sealing alone - the contamination source must be removed first, or sealing traps it inside.
- Humidity-driven mold at boot connections. Pearland’s Gulf Coast climate means any duct breach draws warm moist air. We find mold colonization at supply boots and the blower compartment in homes where sealing was delayed too long.
- Sagging flex runs from original poor support. Tract-home builders often stretched flex duct too tight or supported it with wire that cuts into the insulation. The sag creates low points where debris collects and airflow drops.
Pricing for Duct Repair & Sealing in Pearland, TX

What moves the number: attic access difficulty, number of registers, whether we can reach boots from below or need attic entry, and whether Harvey moisture damage requires remediation before sealing. We assess all of this during the free estimate, put the price in writing, and only start work after you approve it. No per-vent pricing. No coupon that doubles once the truck arrives. Bring a competitor’s written estimate and we’ll provide a free second opinion, our number next to theirs.

FAQs - Duct Repair & Sealing in Pearland
Every 4-6 years for Pearland’s 2000-2018 flex-duct homes, sooner if you’ve had HVAC performance issues or visible dust at registers. The Gulf Coast climate accelerates particulate buildup, and brittle liners in aging systems make aggressive cleaning risky - so we inspect liner condition first and adjust methods accordingly. Call (346) 421-3357 and we’ll assess whether your system is due.
Pearland’s humidity means every duct breach draws warm moist air into the system, creating condensation on cool surfaces and mold colonization at boot connections and coils. In drier markets, leaks waste energy but don’t breed biological growth. Here, sealing is as much an air quality measure as an efficiency one. We seal with mastic, not tape, because it lasts.
Yes, but only with adjusted technique. We start with camera inspection and low-speed agitation - in Silverlake and Shadow Creek Ranch, we’ve learned that standard Rotobrush speeds can fragment liners that have been baking in 140°F attics for 15+ years. If the liner is too degraded, we’ll tell you before touching it, and we’ll quote replacement if that’s the honest answer.
Have the return-air chase and duct liner inspected for latent mold first. Sealing over Harvey moisture damage traps contamination inside the system. We’ve opened chases in Pearland homes where mold was still active six years after the flood, because no one looked before sealing. We remove the source, then we seal. Call (346) 421-3357 for a chase inspection.
A written price agreed on site, then system pressurization to locate leaks, camera inspection of accessible runs, repair or sealing with mastic and mechanical fasteners, and a documented photo record of every duct run before and after. You get the photos, the scope in writing, and the 365-Day Done Right Promise. The visit typically takes 3-5 hours for a standard Pearland home.
In Silverlake, we opened a 2006 flex system in a two-story home and found the original inner liner so brittle from attic heat that our standard Rotobrush agitation tools started shedding plastic into the airstream. We switched to low-speed brushing, then mastic-sealed the separated boot connections at three supply registers and re-insulated the damaged run near the air handler, restoring negative pressure and stopping the visible dust streaks at the ceiling vents. The homeowner noticed the difference the same afternoon.
Pearland’s 2000-2018 master-planned flex-duct systems are now old enough that inner liners in attics routinely exceed 140°F and turn brittle, so experienced crews must lower brush speed and switch to gentler agitation before cleaning - otherwise the liner fragments and repairs escalate from sealing to full flex-duct replacement. This is not a theoretical risk. We adjust our methods on every Pearland job because of it.
