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.

We’ve worked in Stafford long enough to know that most duct calls here aren’t simple fixes. The city’s 1980s and 1990s building stock, much of it garden-style apartments and converted flex-space offices along the Southwest Freeway corridor, carries flex-duct networks that have been opened, extended, and patched by multiple tenants over decades. Our crews dispatch from the Houston office and carry Rotobrush inspection cameras and Nikro negative-pressure equipment sized for these older, tighter Stafford systems.
Why CleanRun Air Duct Cleaning Pearland Is Stafford’s Preferred Duct Repair & Sealing Company
CleanRun has held the same practice since 2013: a written price before work starts, a documented photo record when we leave, and the 365-Day Done Right Promise backed in writing on every job. In Stafford specifically, that means we understand the difference between a duct that can be sealed and one that needs full replacement after moisture intrusion. We’ve documented hundreds of Stafford jobs where the camera showed what agitation tools alone could not reach.
Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and we identify each crew member by name before arrival. Every Stafford customer receives the full photo record, delivered as a standard job document, not an add-on.
Scheduling and dispatch are coordinated from our Houston office, with crews serving Stafford locally. We do not claim same-day dispatch because duct repair is a scheduled, documented job, not an emergency roadside service. What we do promise is that your written estimate will arrive before any work begins, and your photo record will arrive before we leave.
Our Duct Repair & Sealing Services in Stafford
Duct Sealing
Most Stafford duct sealing calls involve metal trunk lines in single-family homes or the rigid duct portions of older apartment HVAC systems. We seal with mastic compound and fiberglass mesh, not tape, because tape fails in Stafford’s persistent humidity. A typical residential duct sealing job in Stafford runs $180-$420 for accessible trunk lines, with commercial systems along US-59 ranging higher depending on plenum access. Every seal is smoke-tested under negative pressure to verify it holds before we close the access panel.
Flex Duct Repair
Flex duct repair is the core of our Stafford work. The garden-style apartment complexes near Stafford Centre and along Murphy Road are filled with original 1980s and 1990s flex duct that has sagged, torn at joints, or disconnected entirely. Repair costs in Stafford typically run $280-$650 per run, including reconnection, reinforcement, and re-insulation. We do not reuse flex duct that has been submerged or shows liner delamination from moisture, a standard we enforce strictly in post-Harvey Stafford properties where floodwater reached ceiling cavities.
Metal Duct Repair
Metal duct repair in Stafford concentrates in the smaller single-family stock and in the rigid trunk portions of commercial systems. We patch with galvanized sheet metal and seal with mastic, or replace sections where corrosion has penetrated. Costs run $320-$780 depending on gauge and accessibility. In Stafford’s high-humidity environment, we also evaluate whether the original insulation jacket can be salvaged or whether the condensation risk requires full rewrap.
Duct Insulation
Duct insulation in Stafford is not an afterthought. Original 1980s fiberglass wraps in this market have compressed, torn, or become moisture reservoirs. We install new insulation with vapor barriers appropriate to Gulf Coast conditions, typically $4-$7 per linear foot for standard R-6 flex duct wraps. Without proper insulation, a sealed leak simply moves the condensation point downstream. We document the before condition photographically so you can see why we recommended replacement versus spot repair.

BeforeAfterTrusted Brands We Service in Stafford
CleanRun crews carry professional-grade equipment from Rotobrush, Nikro, and Honeywell, with Aprilaire components for filtration upgrades where duct repair exposes the system to construction particulate. We stock mastic sealant, flex-duct connectors, and insulation wraps sized for the 6-inch and 8-inch runs common in Stafford’s 1980s and 1990s building stock. That means faster turnaround on standard repairs without waiting on supplier delivery to Sugar Land or Missouri City.
Common Duct Repair & Sealing Problems We See in Stafford Homes
- Post-Harvey flex duct cleaned and reused instead of replaced. After 2017 flooding, some Stafford properties had ducts cleaned and returned to service while the inner liner retained moisture-driven mold. Our camera inspection finds this. When the liner is compromised, we document the damage for replacement, not cleaning.
- Tenant-modified commercial systems with unmapped dead-end branches. Along the US-59 corridor, successive occupants have extended, rerouted, or abandoned duct runs. A seal at the air handler doesn’t stop unfiltered air from a plenum void being pulled back into occupied space through these branches. We map the system with a smoke test before sealing.
- Original 1980s insulation condensing year-round. Stafford’s humidity exceeds 80% regularly, and air conditioning runs nine to ten months. Compressed or torn insulation creates a mold-promoting surface inside the duct envelope. We photograph the condition and specify re-insulation with the repair.
- Undersized return-air configurations restricting airflow. Common in Stafford’s vintage residential stock, this accelerates particulate buildup and creates negative pressure that pulls attic or crawl-space air through leaks. We measure static pressure and document the restriction before recommending duct modification.

FAQs - Duct Repair & Sealing in Stafford
We inspect the inner liner with a Rotobrush camera. If the liner shows delamination, mold penetration, or any evidence that floodwater reached the interior surface, we document this photographically and recommend replacement. Cleaned-and-reused flex duct from post-2017 remediation is a common finding in Stafford, and agitation tools cannot restore a compromised liner. Call (346) 253-1822 and we’ll show you exactly what the camera saw.
Often yes, but only after we map what is actually connected. We run a smoke test to identify live branches versus dead-end extensions, then seal active leaks with mastic and cap abandoned penetrations. The field vignette: we were called to a garden-style apartment complex off Southwest Freeway near Stafford Centre after multiple units reported musty odors coming from the registers. Camera inspection showed the original flex duct had disconnected at a joint above the plenum, and 30 years of tenant reroutes had left two dead-end branches pulling unfiltered air from a crawl space. We sealed the penetration with mastic, reconnected and re-insulated the run, and verified with a smoke test that the supply and return ducts were holding negative pressure under HEPA filtration.
Stafford’s relative humidity routinely exceeds 80% and air conditioning runs nine to ten months, creating persistent condensation risk inside poorly insulated ductwork. A seal that works in a drier climate can become a mold incubator here if the insulation isn’t addressed simultaneously. Our Stafford estimates include insulation condition in the written scope, not as an upsell.
Yes. We package the photo record, static pressure readings, and moisture meter logs into a single document that meets standard adjuster requirements for mechanical system damage. The 365-Day Done Right Promise backs our assessment if questions arise later. We’ve prepared these packages for Stafford commercial properties along US-59 and for residential claims in flood-impacted neighborhoods.
We map it with smoke testing and camera inspection, then deliver a marked diagram as part of your photo record. Unmapped dead-end branches are common in Stafford’s converted flex-space buildings, and sealing without mapping risks pressurizing abandoned runs or pulling unfiltered air from plenum voids. The written scope specifies which branches are active, which are capped, and which require replacement.
