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 been working in Carrollton since 2013, and the housing stock here tells its own story. The city built out fast in the 1970s and 1980s, and those slab-on-grade ranch tracts off Josey Lane, Hebron Parkway, and Marsh Lane still carry original duct systems that weren’t designed for forty years of North Texas clay soil heaving. Our Duct Repair & Sealing team knows the difference between a simple seal job and a system that’s been pulled apart at the joints by seasonal foundation movement. That local pattern recognition matters when you’re deciding whether to reseal or rebuild a run.
Why CleanRun Air Duct Cleaning Frisco Is Carrollton’s Preferred Duct Repair & Sealing Company
Carrollton homeowners make their decisions on evidence, not promises. We deliver a written price before any work starts, every time, under Haven Standard Clause 1. No exceptions. The price we write is the price you pay. Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. You know who’s coming to your door on Marsh Lane or into your condo parking structure off Trinity Mills.
Our documented photo record shows you what we found. On every visit, we photograph the inside of every duct run before and after work. In Carrollton’s older tracts, those photos often reveal delaminating fiberglass duct board, disconnected flex joints at the plenum, or crimped runs where the slab has shifted. You see it. We explain it. Then we fix it.

We’ve served more than 52,000 homes since 2013, every one with a written price before work started and a documented photo record when the crew left. Carrollton is a core market for us. We know the difference between a 1978 ranch near the I-35E corridor and a 2015 build near the Denton County line, and we adjust our inspection protocol accordingly.
Our Duct Repair & Sealing Services in Carrollton

Duct Sealing with Mastic Sealant
Mastic sealant is the standard for permanent duct sealing, not tape. In Carrollton’s 40-to-50-year-old homes, we apply mastic to plenum collars, boot connections, and trunk-line seams where thermal cycling and clay-soil movement have opened gaps. The mastic remains flexible after curing, which matters in a market where foundations still heave seasonally. A typical mastic sealing job for a Carrollton slab ranch with 8-12 duct runs runs $450-$720. We test static pressure before and after to verify the seal.

Flex Duct Repair
Flex duct repair is our most common call in Carrollton. The original flex installed in 1970s and 1980s tracts has kinked, torn, or pulled free at the collar after decades of attic traffic and foundation shift. We replace damaged flex with new insulated duct, secure it with mechanical straps (not tape), and seal the connection with mastic. A single flex run replacement in Carrollton typically runs $180-$340. Full flex replacement in a 1,500-square-foot ranch runs $1,200-$2,100. We photograph the damage before removal so you see why replacement beat resealing.

Metal Duct Repair
Metal ductwork in Carrollton appears mainly in commercial buildings and in the occasional custom home near the Elm Fork. We repair separated seams, patch corrosion holes, and reseal with mastic or specialized metal duct sealant depending on the application. Metal duct repair starts at $220 for accessible seam work. Where metal runs through shared walls in Carrollton’s multifamily buildings, we coordinate access with building management under Haven Standard Clause 5: Property Respect.

Duct Insulation and Air Leak Repair
Air leak repair goes hand-in-hand with insulation replacement in Carrollton attics where original wrap has compressed or fallen away. We identify leaks with pressure testing, seal them, then reinstall insulation to R-6 or R-8 as appropriate. Combined leak repair and insulation for a typical Carrollton ranch runs $680-$1,200. The work matters here more than in milder climates - Carrollton’s sustained 100°F-plus heat indexes from late May through September force attic temperatures that cook uninsulated ductwork and expand every micro-gap.

Common Duct Repair & Sealing Problems We See in Carrollton Homes

- Clay-soil heaving disconnects flex joints. Carrollton’s 1970s-80s slab ranches sit on expansive black clay that swells in wet seasons and shrinks in drought. After forty years, flex duct joints at the trunk and boot collars pull apart behind drywall where a surface inspection never looks. We find these with camera inspection and seal or rebuild depending on damage.
- Fiberglass duct board delaminates and sheds debris. Original fiberglass duct board interiors in Carrollton’s older homes break down after decades of DFW humidity cycling. The camera shows fibrous debris past the registers. Sealing over compromised duct board without replacing it traps the breakdown and accelerates it.
- I-35E corridor homes load heavier particulate. Homes near Carrollton’s stretch of I-35E - one of Texas’s highest-volume truck freight routes - show measurably heavier diesel particulate and carbon buildup in return-air ducts and filters. Sealing leaks in these systems matters more because the infiltration load is higher.
- Shared dryer vent stacks in multifamily buildings. Carrollton’s apartments and condos often run a single dryer lint pathway through multiple units. Sealing one unit’s vent while the shared run above stays packed leaves the fire risk intact. We inspect the full stack before recommending any single-unit seal.

We Also Serve Cities Near Carrollton

Our crews work throughout the northern Dallas-Fort Worth corridor. We regularly schedule Duct Repair & Sealing in Carrollton alongside appointments in Coppell, Richardson, Lewisville, and The Colony. Each city gets the same written-price protocol and documented photo record, but the technical approach differs based on local housing age and conditions. Carrollton’s 1970s-80s slab ranches demand a different inspection mindset than The Colony’s 2000s builds or Coppell’s mixed-era stock.

FAQs - Duct Repair & Sealing in Carrollton

No - sealing only your section would leave lint accumulation and fire risk intact in the shared run above. We inspect the full stack with building management’s coordination, document the condition with photos, and recommend either full-stack cleaning and sealing or a code-compliant individual vent solution if the building allows. Call (940) 290-8552 to schedule a stack inspection - estimates are free.
Carrollton’s suburban buildout peaked in the 1970s and 1980s, leaving dense inventory of 40-to-50-year-old slab ranches whose original flex duct and fiberglass duct board have endured decades of North Texas clay-soil heaving that newer-built cities like Coppell and The Colony simply haven’t experienced at the same scale. Nearly every cleaning job in Carrollton doubles as a duct-integrity inspection. Call (940) 290-8552 for a written assessment of your system.
Yes - homes within close proximity to Carrollton’s I-35E corridor consistently show measurably heavier diesel particulate and carbon buildup in return-air duct interiors and filters compared to quieter residential pockets. The localized contamination pattern means we check filter loading and return-duct deposition more carefully, and we may recommend more frequent inspection intervals. Call (940) 290-8552 to discuss whether your address falls in this pattern.
Yes - we work in Carrollton’s multifamily buildings regularly. Our technicians arrive with portable equipment sized for stairwells and limited parking, and we coordinate with building management for roof or utility-room access under Haven Standard Clause 5: Property Respect. The written price includes any access-time allowance. Call (940) 290-8552 to schedule - we’ll confirm building requirements when you book.
Camera inspection shows the difference. Delaminating duct board sheds visible fibers into the airstream and has a fuzzy, breaking-down interior surface - resealing traps the degradation and accelerates it. Intact duct board with surface wear but no fiber loss can sometimes be resealed with mastic after source removal. We show you the camera footage and explain which condition we found before you decide. Call (940) 290-8552 for an inspection - estimates are free, and the photo record is included.
Schedule Your Carrollton Duct Repair & Sealing Inspection
Carrollton’s clay soil, aging housing stock, and I-35E corridor pollution signature create duct conditions that generic cleaning won’t fix. We inspect with cameras, explain with photos, quote with written prices, and guarantee with a 365-Day Done Right Promise backed in writing. On a slab ranch off the Josey Lane corridor in central Carrollton, our tech ran camera inspection down a 1979 return run and found the original fiberglass duct board delaminating, shedding fibers into the airstream right at the air handler collar. We isolated the run under negative pressure, did source removal with agitation tools, then rebuilt the crimped flex joint and sealed the plenum and boots with mastic. Post-test static pressure dropped and the homeowner’s filter loading finally slowed. That’s the documented difference between vacuum noise and actual repair.
Call (940) 290-8552 for your written estimate. Every call is answered by a live person, and we’ll schedule your Carrollton appointment within two to four business days. Free second opinions on any competitor’s written estimate. No per-vent pricing. No call-for-a-quote. Just a written price, documented work, and a guarantee that follows the truck home.
