AfterTrusted Duct Repair & Sealing for Frisco Homeowners
Duct repair and sealing in Frisco typically costs $280-$1,200 depending on whether you’re sealing accessible joints or replacing collapsed flex runs in an attic, and most jobs are completed in a single visit with a written price agreed before work starts. Since 2013, CleanRun Air Duct Cleaning Frisco has repaired and sealed ductwork in more than 52,000 homes across North Texas, every one with a documented photo record delivered before the crew leaves. We’re independently owned and operated under the Haven Standard, led by Tomas Reyes, and we serve Frisco homeowners from our base throughout the city’s major neighborhoods including Stonebriar, Phillips Creek Ranch, Newman Village, and The Trails. Call (940) 290-8552 for a free written estimate with no obligation to proceed.
Frisco’s construction boom between 2015 and 2022 left thousands of homes with ductwork that was sealed with tape rather than mastic, flex duct that was crushed during drywall installation, or metal plenum connections that have worked loose after eight to ten seasons of expansion and contraction in our 100-degree summers. The result is conditioned air bleeding into attics that reach 140 degrees in July, utility bills that climb year over year despite thermostat discipline, and rooms that never reach the temperature shown on the display. We also serve nearby communities with Duct Repair & Sealing - Little Elm. We find these problems with a visual inspection and, where needed, a duct blaster test that measures actual leakage against the home’s total airflow. Then we photograph every run before touching it, deliver a written price under Haven Standard Clause 1, and photograph again when the work is complete. The customer receives both sets of images as part of the standard job record.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps and separations in your supply and return ductwork where conditioned air escapes before reaching your rooms. In Frisco, we most often find failed tape seals at plenum connections and register boots in homes built between 2015 and 2020, when speed of construction sometimes outpaced proper sealing technique. If you’re in neighboring areas, we also offer our Duct Repair & Sealing in Frisco and surrounding communities. Our crews remove the old tape or degraded mastic, clean the joint surface, and apply new mastic sealant reinforced with mesh tape at every connection point. The work is photographed before and after, and we pressure-test the system where leakage volume warrants verification.
Flex Duct Repair
Flex duct, the insulated flexible tubing that connects your main trunk to individual rooms, is vulnerable to crushing, kinking, and puncture in Frisco’s tight attic spaces. We regularly find flex duct that was pinched against a truss during insulation installation, or that has sagged over time until it forms a low spot where condensation collects and microbial growth follows. CleanRun replaces damaged flex runs with new R-8 insulated duct sized to the original design, supports it with proper straps to prevent future sagging, and seals each end with mastic and a mechanical connection rather than tape alone. The camera shows the crushed restriction before we cut it out, and the new run after installation.
Metal Duct Repair
Galvanized steel ductwork, common in older Frisco homes and in commercial-style residential builds, can separate at seams, corrode at condensation points, or develop holes from contact with roofing nails or electrical work. Metal repair requires cutting out the damaged section, fabricating a replacement piece to match the original gauge and dimensions, and joining it with S-clips and mastic rather than the duct tape that inevitably fails. Our technicians carry sheet metal tools and stock common fittings so most metal repairs are completed without a return visit. Every joint is sealed, every seam is checked, and the repair is photographed from inside the run where access allows.
Duct Insulation
Duct insulation in Frisco attics degrades from radiant heat, moisture, and rodent activity, leaving bare metal or thinly wrapped duct that loses temperature before the air reaches your rooms. We assess insulation condition during our initial inspection and specify replacement with R-8 or R-6 fiberglass wrap, depending on the application and local code requirements. In homes with extensive degradation, we may recommend full duct replacement rather than piecemeal insulation repair, and we put that recommendation in writing with a price for each option so you can decide based on total cost of ownership rather than first cost alone.
Mastic Sealant
Mastic is a water-based sealant that remains flexible after curing, making it the correct material for duct joints that expand and contract with temperature change. Unlike tape, which dries and separates within three to five years in a Texas attic, mastic maintains its seal for the life of the duct system when properly applied. Our crews brush mastic onto every joint, seam, and penetration at a thickness that covers the underlying material completely, then reinforce high-stress areas with embedded mesh. The work is slow and methodical, which is why it is often skipped during original construction and why we budget the time to do it correctly on every sealing job.
Air Leak Repair
Air leak repair addresses the unintended pathways between conditioned space and unconditioned zones, including attic pull-down stairs, recessed can lights, and plumbing chases that connect to wall cavities. In Frisco’s two-story homes with upstairs utility rooms, we frequently find that the return air path is pulling attic air through gaps around the furnace platform, effectively poisoning the air stream with 140-degree dust and fiberglass particles. We seal these leaks with fire-rated foam, mastic, or metal flashing as appropriate, and we photograph the condition before and after so you can verify that the pathway was actually closed, not just described as closed.

Brands We Service for Duct Repair & Sealing
We repair and seal ductwork connected to HVAC equipment from Honeywell, Aprilaire, and every other major manufacturer installed in Frisco homes. Honeywell zoning systems, in particular, require precise duct balancing to function correctly; we’ve serviced hundreds of these installations and understand how damper positions and duct static pressure interact with zone calls. When we seal ducts on a Honeywell-zoned system, we verify that each zone achieves its design airflow and document the readings as part of the job record.
Aprilaire whole-home dehumidifiers and air cleaners integrate with ductwork at specific points that must remain sealed to maintain rated performance. We’ve found installations where the dehumidifier return connection was leaking 15% of its air into the attic, effectively doubling the unit’s runtime and wearing out the compressor prematurely. Our repair restores the seal, protects the equipment investment, and is documented with before-and-after photos of the connection. Whether you have Aprilaire, Honeywell, or any other make, we can assess your duct system and deliver a written repair scope with a fixed price.
BeforeAfterSigns You Need Duct Repair & Sealing Right Now
- Rooms that won’t hold temperature despite a running system. In Frisco’s summer heat, a bedroom that stays 4-6 degrees warmer than the thermostat setting often indicates a disconnected or crushed supply run. The system runs longer, the utility bill climbs, and the compressor cycles more frequently. We map airflow at each register to isolate the problem run.
- Dust accumulation on registers immediately after cleaning. If you’re wiping black debris from supply registers within two weeks of dusting, your return duct may be pulling attic air through a gap in the ceiling plane. The filter cannot catch what enters downstream of the air handler. We inspect the return path with a camera to find the breach.
- Utility bills that rise year over year without rate changes. Duct leakage typically worsens gradually as tape dries, mastic cracks, and flex duct sags. A home that lost 15% of its airflow to leakage in year three may lose 25% by year eight. We compare your current usage to similar Frisco homes and recommend testing when the gap exceeds normal efficiency variation.
- Musty or chemical odors when the system starts. Odors that dissipate after the first few minutes of operation suggest microbial growth or volatile chemical accumulation in a low spot or leak point within the duct system. In Frisco’s humid shoulder seasons, condensation in a sagging flex run creates ideal conditions. We locate the problem with visual inspection and replace the affected material.
- Visible gaps or disconnected duct in accessible areas. Homeowners who inspect their attics sometimes find obvious separations at plenum connections or register boots that have fallen away from the ceiling. These are not cosmetic issues; they represent direct loss of conditioned air and potential safety hazards if combustion gases are backdrafted. We recommend professional repair and do not advise homeowner sealing of connections near gas appliances.
Our Duct Repair & Sealing Process - Step by Step
- 1
Scheduled arrival with named technician. Your appointment is confirmed by text with the technician’s name and photo. Our crews are background-checked, uniformed, and operate under Haven Standard Clause 3: Verified Crews. We arrive within the scheduled window and begin with a walkthrough of your concerns.
- 2
Visual inspection and diagnostic testing. We inspect accessible ductwork with a borescope camera, measure static pressure at the air handler, and where leakage is suspected, perform a duct blaster test that quantifies total system leakage against the conditioned floor area. The camera records the interior condition of every run we can access.
- 3
Written scope and fixed price. Before any repair begins, we deliver a written scope that identifies each problem found, the repair method, and a single fixed price for the complete job. Haven Standard Clause 1 requires this; there is no “call for a quote” and no per-vent pricing that balloons once work starts. You approve the scope or decline with no charge for the diagnostic.
- 4
Repair execution with photographic documentation. Our technicians complete the approved work using professional-grade tools and materials from Rotobrush, Nikro, Abatement Technologies, and Guardsman as appropriate for the application. Every run is photographed before repair, during key stages, and after completion. The images are uploaded to your job record in real time.
- 5
Verification and final documentation. We retest static pressure and, where duct blaster testing was performed, verify that leakage has been reduced to acceptable levels. You receive the complete photo record, the written scope with final pricing, and the 365-Day Done Right Promise in writing before we leave. If the work is not right, we make it right.
How Much Does Duct Repair & Sealing Cost in Frisco?
A typical duct sealing job for a Frisco home with 8-12 accessible joints runs $280-$550, depending on whether we can reach all connections from the attic or if some require ceiling access. For a detailed breakdown, see our guide on how much Duct Repair & Sealing costs. Flex duct replacement for a single crushed run costs $180-$340 including materials and labor. More extensive repairs, including multiple flex runs, metal fabrication, or full plenum rebuild, range from $600-$1,200 based on material type and access difficulty. These are whole-system prices agreed in writing before work starts, not per-vent rates that accumulate as the crew works.
Several factors affect where your job falls in these ranges. Attic temperature and clearance determine how long technicians can work continuously; Frisco’s July and August afternoons sometimes require split shifts that extend labor hours. The age and condition of existing ductwork affects whether we can repair in place or must replace sections to achieve a lasting seal. Homes with spray foam attic encapsulation present access challenges that standard vented attics do not. And the original construction quality matters: we’ve found Frisco homes where every register boot was sealed with painter’s tape, requiring complete re-sealing, and others where only two or three joints needed attention.
To avoid overpaying, reject any quote that cannot explain what specific problems were found and how the price was calculated. A legitimate duct repair estimate identifies the location and nature of each defect, specifies materials by type and quantity, and presents a single total. Be cautious of $79-$149 “sealing specials” that cover only a visual inspection and tape application at visible joints; these do not address the hidden leakage that drives utility costs. CleanRun’s free estimate includes diagnostic testing where indicated, a written scope with line-item clarity, and a fixed price that does not change unless you request additional work. Call (940) 290-8552 for your estimate.

Frequently Asked Questions - Duct Repair & Sealing in Frisco
Duct repair and sealing fixes the physical structure of your duct system, closing gaps, replacing damaged sections, and restoring proper airflow paths, while duct cleaning removes accumulated debris from intact ductwork. In Frisco, we often perform both services on the same visit when inspection reveals both leakage and contamination. The repair work is permanent structural correction; cleaning is maintenance that should follow repair so debris isn’t drawn into newly sealed joints.
Most single-issue repairs, such as sealing accessible joints or replacing one flex run, are completed in two to four hours. More extensive work involving multiple runs, metal fabrication, or attic access challenges may extend to a full day. We specify the expected duration in your written scope so you can plan accordingly, and we do not leave mid-job unless the condition is unsafe or requires parts we do not stock.
Typical duct sealing runs $280-$550, single flex duct replacement $180-$340, and extensive repairs up to $1,200 depending on access and materials. Every job is quoted with a written price before work begins under Haven Standard Clause 1, with no per-vent pricing or post-work add-ons. Call (940) 290-8552 for a free estimate specific to your home’s condition.
Yes, we repair and seal ductwork connected to Honeywell zoning controls, Aprilaire dehumidifiers and air cleaners, and all other major brands installed in Frisco homes. Our technicians understand how these integrated systems interact with duct static pressure and airflow, and we verify proper operation after repair. Bring us any brand; we document the same photo record and written guarantee.
We prioritize calls involving disconnected ducts, conditions that risk HVAC equipment damage, or situations where conditioned air loss creates safety concerns such as extreme indoor temperatures for vulnerable residents. All calls are answered by a live person who can assess urgency and schedule accordingly. For non-emergency repairs, we typically schedule within three to five business days.
Every repair is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, documented in writing on every job. This is not a policy subject to manager approval; it is a written guarantee delivered with your job record. For materials, we honor manufacturer warranties on Abatement Technologies, Guardsman, and other specified products we install.
Clear access to your attic hatch, utility room, and all registers so our technician can inspect and photograph without obstruction. If you have pets, secure them in a separate area; our technicians carry identification but animals respond unpredictably to unfamiliar people in attic spaces. You do not need to move furniture or cover belongings; we protect work areas as part of standard practice. Have your recent utility bills available if you’ve noticed cost increases; they help us correlate consumption patterns with leakage findings.
