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.

AfterFast, Reliable Duct Repair & Sealing Across Lockport
Duct repair and sealing in Lockport typically costs $280-$650 for most residential jobs, with full-system resealing of a 2000s-era tract home running $480-$920. CleanRun crews are dispatched to Lockport from our Chicago scheduling office, and we carry the mastic, metal duct, and flex inventory to handle same-visit repairs in every neighborhood from the historic canal district to the Route 7 subdivisions. Call (331) 236-5490 for a written estimate before any work starts.
We’ve been in enough Lockport basements to know the difference between a duct that can be saved and one that needs to come out. The Des Plaines River valley traps moisture against foundation walls, especially in older homes near the I&M Canal corridor. After a storm or sewer backup, homeowners want to know whether their ducts need cleaning or actual replacement. Our Duct Repair & Sealing team documents that line with photos an adjuster can read.
Why CleanRun Air Duct Cleaning Naperville Is Lockport’s Preferred Duct Repair & Sealing Company
CleanRun has served Lockport since we opened in 2013, and the pattern here is unmistakable. The 2000s Will County boom built thousands of homes in a narrow window, and most were occupied without post-construction duct cleaning. We find original drywall dust and fiberglass fragments in return-air plenums on street after street. That repetition means our technicians know what to look for before the camera goes in.
Our crews are background-checked, uniformed, and identified by name before arrival, operating under Haven Standard Clause 3: Verified Crews. Every job starts with a written price and ends with a Documented Photo Record of every duct run, delivered as a standard deliverable. The 365-Day Done Right Promise applies in writing, not as a verbal assurance.
We coordinate scheduling from our Chicago office, but the trucks that roll to Lockport carry the equipment for this specific market: Rotobrush inspection systems, Nikro negative-pressure extractors, and Guardsman sealants. We don’t call for parts after we’ve seen your basement.
Our Duct Repair & Sealing Services in Lockport
Duct Sealing with Mastic Sealant
Unsealed joints and disconnected boots pull humid basement air into your supply and return streams, especially after Lockport’s spring storms wick moisture through foundation walls. We seal every accessible joint with mastic, not tape alone, because tape fails when humidity cycles. A typical mastic sealing job in Lockport runs $340-$580 for a standard 2000s tract home with 8-12 registers. Haven Standard Clause 1: written price before the first panel comes off.
Flex Duct Repair
Builder-grade flex duct in the Route 7 and Division Street subdivisions sags, kinks, and tears where rodents or improper support have damaged the outer jacket. We don’t patch and leave. Our crews replace crushed or torn runs with properly supported metal duct where the application calls for it, or with new flex where metal won’t fit the chase. Flex duct repair in Lockport typically runs $180-$420 per run, depending on accessibility and length.
Metal Duct Repair
The pre-WWII and Victorian-era homes near the Illinois & Michigan Canal district often have older, irregularly sized galvanized duct that corrodes at the seams or separates at the collars. We fabricate replacement sections to fit existing dimensions, seal with mastic, and photograph the repair for your records. Metal duct repair in these Lockport homes runs $260-$550 per section.
Duct Insulation
Uninsulated or water-damaged duct wrap in Lockport’s humid basements and crawlspaces drives up heating bills and promotes condensation inside the chase. We replace saturated insulation with closed-cell wrap rated for below-grade applications. A typical insulation replacement for a Lockport basement trunk line runs $320-$680.

CleanRun stocks parts and sealants from Abatement Technologies, Guardsman, and Rotobrush for Lockport jobs, so we’re not ordering overnight while your system sits open. Our Nikro negative-pressure extractors pull debris under controlled HEPA filtration, which matters when we’re removing 15-year-old construction dust from a Route 7 subdivision plenum. You can look up every brand we name. We don’t use equipment we can’t document.
Common Duct Repair & Sealing Problems We See in Lockport Homes
- Post-flood microbial growth in canal-district ductwork. Rooms over damp basements in the I&M Canal corridor show visible growth inside older, irregularly sized metal runs. Homeowners often request cleaning when the saturated sections actually need replacement. We photograph the interior and note moisture readings so you have documentation for your insurer.
- Crushed or unsupported flex duct in 2000s subdivisions. The Route 7 and Division Street corridors were built fast, and duct chases were often an afterthought. We find flex runs pinched against joists, sagging below insulation, or torn by rodent activity in crawlspaces. Mastic-and-tape patches fail because the underlying run lacks proper support.
- Storm-driven moisture wicking into unsealed joints. After water enters a Lockport basement, it doesn’t stay at floor level. Humid air gets pulled into supply and return streams through gaps at the air handler, return plenum, and register boots. Sealing those leaks stops the cycle of damp air recirculation.
- Original construction debris still loading return plenums. In the 2004-2008 subdivisions, we routinely find return-air plenums packed with drywall dust and fiberglass fragments because no post-construction cleaning occurred before occupancy. That debris restricts airflow and accelerates filter loading until it’s removed under negative pressure.

FAQs - Duct Repair & Sealing in Lockport
Sometimes, but not when the duct material itself has been saturated. If water reached the interior of metal duct runs in a canal-district home and microbial growth is visible on the camera, cleaning won’t restore the substrate. We photograph the interior, record moisture readings at multiple points, and mark which sections can be cleaned under negative pressure and which need replacement. That documentation goes to you and your insurer. Call (331) 236-5490 if you’ve had water in your basement and want the line drawn clearly.
They were built and sold in the same narrow window during the 2000s Will County boom, with identical builder-grade flex-duct systems and no post-construction cleaning. Now those homes are hitting the 15-20-year mark together. The flex duct is sagging, the mastic was never applied at key joints, and the return plenums still hold original construction debris. We find the same failure modes on entire blocks. Call (331) 236-5490 for an inspection if your home went up between 2004 and 2008.
We deliver a Documented Photo Record that shows moisture readings, interior condition before any work, and the specific points of separation or saturation. CleanRun has produced these records on every job since 2013. The photos are time-stamped, geotagged to your Lockport address, and paired with a written scope that separates cleaning from replacement. Adjusters recognize documentation that predates the claim. Call (331) 236-5490 if you need a third-party-verified record for your insurer.
It helps, but it doesn’t fix the source. The Des Plaines River valley traps moisture against older foundations, and unsealed duct joints pull that humid air into your airflow. Mastic sealing stops the infiltration at the duct. We combine sealing with dehumidification recommendations for the basement itself. A typical sealing job in a canal-district home runs $380-$620. Call (331) 236-5490 for a written assessment of your specific system.
Our technician arrives in a marked vehicle, identified by name, and performs a camera inspection of every accessible duct run. We show you the interior footage, deliver a written price before any repair begins, and execute the work with Rotobrush and Nikro equipment under HEPA containment. Every run is photographed after repair. You receive the photo record and a written warranty under the 365-Day Done Right Promise before we leave. The standard visit for a Lockport tract home takes 3-5 hours. Call (331) 236-5490 to schedule.
We were called to a 2004 tract home off Division Street where the homeowner noticed supply registers in two bedrooms blowing noticeably weaker than the rest of the house after a summer storm sent water into the basement. A camera inspection found a crushed flex-duct run pinched against a floor joist and a return plenum still holding original construction drywall dust, so our tech rebuilt the run with metal duct, sealed the joints with mastic, and pulled the debris under negative pressure with HEPA filtration. When the system was rebalanced, airflow at those registers matched the rest of the home.
Because Lockport’s 2000s-era tract homes along the Route 7 and Division Street corridors were built and sold in the same narrow window, we find the same construction-debris load - drywall dust and fiberglass fragments packed into return-air plenums - in house after house on the same block, so a repair-and-seal visit often turns into a first-time source-removal job that no prior contractor ever performed. That pattern is specific to Lockport’s build history, and it’s why we carry the equipment for both repair and deep extraction on every truck.
