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.

Why CleanRun Air Duct Cleaning Sugar Land Is Stafford’s Preferred Duct Repair & Sealing Company
We’ve been documenting every duct run we touch since 2013, and Stafford’s building stock has given us some of the clearest before-and-after records in our files. The city’s unusual concentration of tilt-wall warehouses and multi-tenant office parks along US-90A means our commercial duct sealing work here outpaces residential calls two-to-one, a ratio we don’t see in Sugar Land or Missouri City. That commercial density has forced us to master long-run rooftop unit balancing and restricted-staging access that suburban tract-home specialists rarely encounter.
Our Stafford customers receive the same deliverable on every job: a written scope and price before work starts, a 365-Day Done Right Promise backed in writing, and a Documented Photo Record showing the interior of every duct run before and after. No manager-approval games. Haven Standard Clause 1: Written Price Before Any Work Starts. Haven Standard Clause 3: Verified Crews. Tomas Reyes built this standard into the company’s first job and hasn’t waived it since.
We don’t dispatch to Stafford from a satellite office with rented equipment. Our Houston-coordinated crews arrive in marked vehicles with Rotobrush, Nikro, and Abatement Technologies systems we own and maintain. Background-checked, uniformed, identified by name before arrival. The H.A.V.E.N. Standard isn’t marketing language; it’s the checklist our technicians sign on every Stafford job.
Our Duct Repair & Sealing Services in Stafford
Duct Sealing
Stafford’s subtropical humidity makes leaky ducts expensive in ways that don’t show up in drier markets. When your supply or return runs pull 90-degree attic air through gaps at plenum joints or register boots, the system works harder and the moisture load spikes. We seal with mastic compound and metal-backed tape rated for Texas heat, then pressure-test to verify the seal holds. On a recent Stafford warehouse near Murphy Road, we dropped post-seal leakage from 34% to 7% of total airflow.
Flex Duct Repair
The 1970s-1990s tract homes off Staffordshire Road and around the First Colony Mall perimeter are full of flex duct that has sagged, torn at the collar, or collapsed where support straps failed. We don’t patch and pray. Our crews cut back to solid metal, install a new flex section with mechanical fasteners, and seal the joint with mastic. The photo record shows the repair location and the finished connection. If the entire run is degraded, we quote replacement in writing before proceeding.
Metal Duct Repair
Commercial buildings in Stafford’s warehouse corridors run galvanized steel duct from rooftop HVAC units through ceiling plenums that can stretch 200 feet. We’ve found rust-through at condensate drip points, separated seams from thermal expansion, and access panels that were never resealed after filter changes. Our metal repair includes seam sealing, patch welding where structurally indicated, and re-coating with mastic to prevent recurrence. Every repair is photographed and mapped to the building’s mechanical drawings when available.
Duct Insulation & Mastic Sealant
Original fiberglass duct board in Stafford’s older homes wasn’t designed to survive a hurricane. When Harvey floodwater wicked into return-air plenums on the city’s lower-lying western blocks, it saturated the insulation and created mold colonies that standard remediation crews often missed. We don’t seal over contaminated board. Our protocol: camera inspection, source removal under negative-pressure HEPA extraction, then replacement or re-insulation with closed-cell materials where indicated, finished with mastic sealant at all joints. Sealing over mold traps the problem. We document what’s actually there first.

BeforeAfterTrusted Brands We Service in Stafford
Our equipment roster includes Rotobrush agitation systems, Nikro HEPA-negative-pressure extractors, and Honeywell airflow verification tools. We stock mastic sealant, mechanical fasteners, and replacement flex duct in our Houston warehouse, so Stafford jobs aren’t delayed waiting on parts shipments. For commercial clients with Honeywell or Aprilaire controls integrated into their building automation, we coordinate sealing work with your mechanical contractor to avoid triggering false pressure alarms. The brands are named here so you can verify specifications independently before we quote.
Common Duct Repair & Sealing Problems We See in Stafford Homes
- Harvey-saturated fiberglass duct board still in service. In Stafford’s older western residential blocks, we regularly pull registers and find blackened fiberglass liner that floodwater reached years ago. The remediation certificate on the wall says complete. The camera says otherwise. Sealing over this material traps mold spores in the airstream.
- Sagging flex duct from 1980s tract construction. Stafford’s humidity softens the wire helix in old flex runs, causing them to belly out and collect condensation. The sag creates a low point where water pools, then rusts the collar or tears the inner liner. We see this pattern repeatedly in homes near Staffordshire and around the original First Colony development edges.
- Shared dryer vent stacks in multi-unit buildings. Stafford’s apartment complexes along US-90A often route dryer exhaust through a common vertical run. The lint trap in each unit is clean, but the shared pathway isn’t, and restricted parking limits equipment staging. We coordinate with property management to access the stack and seal disconnected joints that are pulling humid laundry air into return plenums.
- Unbalanced commercial rooftop systems shifting leakage downstream. A tilt-wall warehouse near Murphy Road had one branch sealed by another contractor. The airflow simply found the next weakest joint. We map the full system, balance dampers, and seal proportionally so the fix holds.

FAQs - Duct Repair & Sealing in Stafford
Multi-unit buildings along US-90A have shared dryer vent stacks, restricted parking for extraction equipment, and property management approval requirements that single-family homes don’t. We coordinate access with your building manager, stage Nikro HEPA units in loading zones during off-peak hours, and seal common runs only after notifying affected units. Call (346) 421-3357 and we’ll walk through your building’s specific access constraints before quoting.
Only after verifying the duct board isn’t harboring mold. In Stafford’s lower-lying western blocks, we’ve found original fiberglass liner that absorbed floodwater and was never replaced despite remediation certificates. We camera-inspect first. If the board is clean, we seal with mastic. If it’s contaminated, we quote removal and replacement in writing before any sealing work. Sealing over mold makes the air quality worse, not better.
Stafford sits in the Houston metro’s subtropical humidity belt, where indoor relative humidity regularly spikes and AC cycling creates condensation inside ductwork. The flat, slow-draining terrain straddling Fort Bend and Harris counties keeps indoor moisture intrusion elevated year-round. Dallas and San Antonio have drier climates and faster drainage; their ducts don’t stay wet long enough for the mold colonization we document routinely in Stafford. Call (346) 421-3357 for an inspection if you’re catching musty air from registers.
Yes. Tilt-wall warehouses and multi-tenant office parks near Murphy Road run long duct spans from rooftop HVAC units through ceiling plenums with limited access points. Sealing one branch without balancing the full system shifts leakage downstream. We pressure-test the entire network, map airflow with Honeywell verification tools, and seal proportionally. The staging is also different: we need flat ground for equipment near loading docks, not driveway access.
A disconnected or leaking joint in a shared dryer vent stack pulls humid, lint-laden air into the building’s return plenum, increasing moisture load and contamination across all connected units. We’ve sealed these junctions in Stafford complexes where the individual traps were clean but the common pathway was compromised. The repair requires building-wide coordination that single-family duct sealing doesn’t. We handle the logistics and document the before-and-after photo record for your property manager.
