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 Richardson
Duct repair and sealing in Richardson typically runs $340-$780 for a whole-home system, with most jobs completed in a single visit after a written quote. If your home was built between 1965 and 1985 in neighborhoods like Canyon Creek or along the Arapaho corridor, there’s a fair chance your flex-duct joints have worked loose from slab movement. That’s not a guess. We’ve photographed it hundreds of times.
We’re Duct Repair & Sealing technicians who serve Richardson from our Dallas-Fort Worth office, and we know the local housing stock. Ranch-style brick homes with original attic-run duct systems are the norm here, not the exception. Our crews carry Rotobrush and Guardsman equipment specifically for the flex-duct and mastic sealant work these homes need. Call (940) 290-8552 and we’ll put a written price in front of you before any panel comes off.
Why CleanRun Air Duct Cleaning Frisco Is Richardson’s Preferred Duct Repair & Sealing Company
We’ve been documenting the inside of Richardson ductwork since 2013. Every job starts with a written price under Haven Standard Clause 1 and ends with a photo record of every duct run, before and after. No exceptions.
Our Richardson customers tend to find us after a summer Oncor bill shocks them. The pattern is predictable: 40-55-year-old flex duct, detached at the plenum from years of slab movement, bleeding conditioned air into the attic. We show them the photo. We show them the written scope. Then we seal it.
Technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise applies to every Richardson home we touch. If it’s not right, we make it right. In writing, not as a favor.
We also offer a Free Second Opinion on any written estimate from another company. Bring us their number. We’ll put ours next to it, line item by line item, and you can decide which one has the documentation to back it up.
Our Duct Repair & Sealing Services in Richardson
Flex Duct Repair
Richardson’s expansive black clay soil shifts slabs enough that Canyon Creek and Arapaho-corridor homes built 1965-1985 regularly show flex-duct joints pulled loose at the air handler plenum. This is conditioned-air loss that inflates Oncor bills for years, often undiagnosed. We use Guardsman flex repair materials and negative-pressure source removal to restore the run, then photograph the repair so you can verify the work.
We responded to a Canyon Creek ranch home where an aging system revealed crushed flex duct and a detached boot at the air handler plenum, classic slab movement from Richardson’s expansive clay. After a camera inspection and negative-pressure source removal, we used mastic sealant and Guardsman flex repair to reconnect the run, restoring proper supply and return airflow and cutting the homeowner’s summer cooling loss.
Mastic Sealant Application
Mastic is a thick, brush-applied sealant that fills gaps in metal trunk lines and at plenum connections where tape has dried and failed. In Richardson’s older homes with original sheet-metal ductwork, we find tape degraded from decades of attic heat cycling, 140°F in July, 40°F in January. Mastic outlasts tape by a wide margin. We apply it, photograph the coverage, and include that in your job record.
Air Leak Repair
Air leaks in Richardson homes fall into two categories: leaks from mechanical separation (slab movement, crushed flex) and leaks from material failure (dried tape, corroded metal, failed insulation). Our crew pressurizes the system, identifies loss points with a smoke pencil or thermal camera, then repairs and seals. Every leak location is noted in your written scope. Every repair is photographed.
Duct Insulation
Original insulation on Richardson attic-run ducts has often compressed or torn from decades of heat and technician traffic. We replace with foil-faced insulation rated for North Texas temperature extremes, sealed at seams to prevent condensation in humid shoulder seasons. This matters in Richardson, where AC runs hard from May through September and attic temperatures routinely exceed 130°F.
Metal Duct Repair
Sheet-metal trunk lines in Richardson’s 1960s-1980s homes suffer from corrosion at seams and from previous DIY repairs with incompatible materials. We cut out damaged sections, fabricate replacements, and seal with mastic. The work is slower than flex-duct repair but lasts longer. We quote it separately, in writing, before starting.
Duct Sealing
Whole-system duct sealing in Richardson addresses the cumulative effect of decades of small leaks: at registers, at plenums, at joints between flex and metal. We seal what can be sealed, replace what cannot, and deliver a photo record showing the difference. Typical cost for a whole-home seal in Richardson: $450-$680, depending on system size and accessibility.

Common Duct Repair & Sealing Problems We See in Richardson Homes
- Slab movement pulls flex-duct joints loose at the plenum. Richardson’s expansive black clay soil shifts continuously, separating conditioned-air pathways and dumping cooled air into the attic. Homeowners notice it first as a summer Oncor bill that climbs year over year with no change in thermostat setting.
- Decades of lint and allergen buildup restrict airflow and overload the blower motor. Original 1965-1985 attic-run systems in Canyon Creek and Arapaho-corridor homes collect material that newer systems with better filtration never see. The blower works harder, wears faster, and fails sooner.
- Crushed or detached flex sections go undiagnosed for years. These are often hidden above insulation or behind attic decking. A routine cleaning inspection with a camera is frequently the first time a homeowner sees the damage that has been silently raising their energy bills.
- Winter cedar pollen and spring tree pollen drive heavy return-air infiltration. Richardson’s mature neighborhoods, especially those with established live oaks and cedar elms, load return systems with particulate that overwhelms standard filters and deposits in ductwork, accelerating material buildup and microbial growth in humid summer conditions.
Pricing for Duct Repair & Sealing in Richardson, TX
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts. Here is what duct repair and sealing costs in Richardson’s market:
| Service | Typical Range |
|---|---|
| Single flex-duct repair (one run) | $180-$290 |
| Multiple flex-duct repairs (2-4 runs) | $340-$520 |
| Whole-home mastic sealant application | $450-$680 |
| Metal duct section repair/replacement | $280-$450 per section |
| Duct insulation replacement (whole system) | $520-$780 |
| Comprehensive air leak repair + sealing | $560-$840 |
Factors that move the number: attic accessibility, extent of slab-movement damage, whether the air handler location requires additional safety protocols, and whether prior repairs used incompatible materials that must be removed. We assess all of this during our initial inspection, put the scope and price in writing, and only then ask for your approval. No per-vent pricing. No coupon that balloons once the truck arrives. Call (940) 290-8552 for a free estimate.

FAQs - Duct Repair & Sealing in Richardson
It pulls flex-duct joints loose at the air handler plenum, creating conditioned-air loss into the attic that raises cooling bills and strains the blower motor. This soil-driven mechanical separation is specific to older homes on shifting slabs and is rarely seen in newer, geologically stable suburbs. We diagnose it with camera inspection and seal with mastic and Guardsman flex repair. Call (940) 290-8552 for an exact quote, estimates are free.
Canyon Creek homes were built during Richardson’s peak suburban buildout from the late 1960s through early 1980s, meaning original duct systems are now 40-55 years old and have endured decades of North Texas thermal cycling and slab movement. Allen and Frisco’s master-planned subdivisions use newer materials, better initial sealing, and sit on more stable geology. The combination of age and soil stress makes Richardson’s older stock more prone to leak development. We inspect and quote before any work begins.
We start with a camera inspection of every duct run, identify separation points and material failures, then deliver a written scope and price. Approved work includes negative-pressure source removal of debris, repair or replacement of damaged flex or metal sections, mastic sealant application at all joints, and replacement of degraded insulation. Every step is photographed before and after, and the complete record is delivered as a standard job deliverable. Most Richardson jobs are completed in one visit.
Homes with original 1965-1985 duct systems in Richardson should be inspected every 3-4 years, with cleaning and sealing performed when camera inspection shows debris buildup or measurable air loss. The combination of heavy AC use from May through September and pollen loading from mature neighborhoods accelerates both contamination and material fatigue. Newer homes with stable slabs and modern ductwork can go 5-7 years between services. We’ll tell you what your system actually needs after we look inside.
Yes. Loose ducts force the blower motor to work harder to maintain airflow, shortening its lifespan and increasing energy draw. Simultaneously, attic air pulled through leaks bypasses your filter entirely, introducing insulation particles, dust, and microbial material into conditioned space. We’ve photographed this exact pathway in Richardson homes where the homeowner’s “allergies” resolved after sealing. The repair is straightforward once identified. Call (940) 290-8552 and we’ll show you what’s happening in your system.
