We’re based right here in Pearland, not dispatched from Houston with a GPS and a prayer. Since 2013, we’ve served more than 52,000 homes across Brazoria and Harris counties, including Friendswood Duct Repair & Sealing, and the pattern we see in Pearland is specific: homes built between 2015 and 2020 in subdivisions like Shadow Creek Ranch and Silverlake often have flex duct runs that were installed fast and sealed poorly at the plenum connections. The camera doesn’t lie. When we open a return in a Pearland attic in July, we regularly find gaps at the collar where mastic was skimped or never applied, blowing conditioned air directly into 140-degree attic space. That’s not a comfort problem. It’s a utility bill problem, and it’s measurable.
Tomas Reyes leads our operation under the H.A.V.E.N. Standard, and every technician who enters your home is background-checked, uniformed, and identified by name before arrival. We don’t do urgency theatre. We do documented work with a written price, a photo record, and a warranty you can hold in your hand.
What Our Duct Repair & Sealing Service Includes
Duct Sealing
Duct sealing closes the gaps, cracks, and disconnected joints in your forced-air system where conditioned air escapes before reaching your rooms. In Pearland, we see this most often at the plenum (the main distribution box attached to your air handler), where thermal expansion and the Gulf Coast humidity cycle loosen tape and mastic over time. Our crew seals these points with professional-grade mastic and reinforced mesh, then pressure-tests the repair to verify the seal holds under operating conditions. Every sealed joint is photographed before and after, and the images are delivered with your job record.

Flex Duct Repair
Flex duct, the insulated flexible tubing common in Pearland homes built after 2005, crushes, tears, or pulls loose at its connections when attic temperatures spike or rodents access the space. We don’t patch flex duct with tape and hope; we cut back to sound material, install a new collar or sleeve, and secure it with tension straps and mastic. In neighborhoods like Sunrise Lakes and Lakes of Highland Glen, we’ve replaced entire flex runs where the original installer used zip ties instead of proper metal straps. The repair is photographed at three points: the damage, the preparation, and the finished connection.

Metal Duct Repair
Older Pearland homes, particularly in the original sections near Old Townsite and along Broadway, often have galvanized steel ductwork that corrodes at the seams or separates at the drive cleats. Metal duct repair requires sheet metal screws, fiberglass mesh, and high-temperature mastic to rebuild the pressure boundary. We also check for internal rust scale that can break loose and circulate through your supply registers. When we find it, the customer sees the photo before we discuss options.

Duct Insulation
Uninsulated or degraded duct insulation in a Pearland attic is a direct transfer of your money to the outdoors. The fiberglass wrap on flex duct compresses over time, and the vapor barrier jacket tears, exposing the insulation to attic moisture. We install new insulation with a proper vapor barrier, sealed at all seams, to maintain the thermal boundary between conditioned air and attic ambient. In Pearland’s climate, where attic temperatures exceed 130 degrees for months each year, this matters more than equipment efficiency ratings.

Mastic Sealant
Mastic is the thick, paste-like sealant that forms the permanent bond at duct joints; foil tape alone fails within years in a hot attic. We apply mastic with a brush or caulking tube, then embed fiberglass mesh at stress points for reinforcement. The difference between a taped joint and a mastic-sealed joint is visible on our thermal camera, and we show the customer both images. Haven Standard Clause 1 requires the written price before work starts; Haven Standard Clause 4 requires the photo record that proves the work was done.

Air Leak Repair
Air leaks in ductwork are often invisible to the homeowner but obvious to a pressure gauge. We pressurize the system and use a smoke pencil or theatrical fog to locate leaks at seams, corners, and register boots. In two-story Pearland homes, we commonly find leaks at the floor joist penetrations where the duct passes from the attic to the second floor. Each leak is sealed, tested, and photographed. The pressure test results are noted on your written job record.

Brands We Service for Duct Repair & Sealing

CleanRun works with duct systems connected to all major HVAC brands, and we stock components from manufacturers whose specifications we can verify. We’ve serviced hundreds of systems with Aprilaire media air cleaners and fresh air ventilators, and we understand how their duct connections must be sealed to maintain the rated airflow without bypassing filtration. Our crews also regularly repair ductwork serving Abatement Technologies HEPA filtration systems, where leak-free negative-pressure containment is the entire point of the installation.
Whether your Pearland home has a Rotobrush-agitated cleaning port, a Guardsman-coated flex run, or any other configuration, we can assess it, price it in writing, and repair it to manufacturer specification. We don’t guess at compatibility. We check the model, pull the spec sheet, and do the work accordingly. If you have a written estimate from another company, bring it. We’ll deliver a free second opinion with our number next to theirs.
Before
AfterSigns You Need Duct Repair & Sealing Right Now
- Your upstairs rooms stay hot while downstairs over-cools. This temperature split often means conditioned air is leaking into the attic before reaching the second-floor registers. In Pearland’s two-story homes, we see this at the flex duct connections above the staircase chase, where the duct has pulled loose from the boot.
- Your energy bills spike in summer with no change in thermostat setting. A 15-20% increase in kWh usage between May and September, without a rate change, frequently traces to duct leakage forcing your compressor to run longer. The lost capacity isn’t in the equipment; it’s in the distribution system.
- You feel weak airflow at registers farthest from the air handler. This can indicate a crushed flex duct, a disconnected joint, or a significant leak bleeding pressure before the terminal point. We measure static pressure and airflow at each register to isolate the failure.
- Your attic insulation has dark streaks or compressed patches. These marks show where conditioned air has been blowing against the insulation for months or years, creating a thermal bypass. The duct leak is upstream of the discoloration, and the repair requires opening the ceiling or accessing the attic.
- You smell attic air or dust when the system cycles on. A return duct leak in the attic pulls unfiltered, superheated air directly into your system and distributes it through the house. In Pearland, this often includes fiberglass particles, rodent debris, and pollen. It’s a health concern, not just a comfort issue.
Our Duct Repair & Sealing Process - Step by Step

- 1
System inspection and pressure testing. We start with a visual assessment of accessible ductwork and a static pressure test to quantify system performance. The pressure reading tells us whether the problem is in the equipment, the ducts, or both. We explain the number and show you where it falls relative to manufacturer specification.
- 2
Leak detection with smoke or thermal imaging. Using a theatrical fog generator or FLIR thermal camera, we locate the exact points where conditioned air escapes. In Pearland attics, we often find multiple small leaks rather than one obvious failure; each is marked and photographed.
- 3
Written scope and price, delivered before work begins. Haven Standard Clause 1: no exceptions. You receive a written description of every repair, the materials to be used, and the total price. If the scope changes during work, we stop, document the finding, and get written approval before continuing.
- 4
Repair and seal with documented photography. Our crew performs the work using mastic, mesh, mechanical fasteners, and replacement sections as specified. Every duct run is photographed before and after. The images are not marketing; they’re part of your job record, delivered with the invoice.
- 5
Post-repair pressure test and photo record delivery. We re-test static pressure to verify improvement, then compile the photo record, pressure readings, and warranty into a single document. The 365-Day Done Right Promise is included in writing. If the repair fails, we make it right without renegotiation.
How Much Does Duct Repair & Sealing Cost in Pearland?
A typical duct sealing job in Pearland runs $280-$480 for a single system with accessible attic ductwork and 8-12 identified leak points. Flex duct repair, where we replace a damaged section or reconnect a pulled joint, typically falls between $180-$340 per run. Metal duct repair involving rust remediation and seam rebuilding ranges from $320-$620 depending on linear footage and access difficulty. Full duct insulation replacement on a 2,000-square-foot home generally costs $580-$780.
Several factors move these numbers. Attic access is the first: a truss attic with a permanent floor and lighting takes less time than a tight cape cod with blown-in insulation covering every joint. The extent of damage matters too; a single disconnected flex duct is a 45-minute repair, while a system with corroded metal duct throughout the return path requires section-by-section replacement. Material type affects price because metal work demands sheet metal fabrication and more labor hours than flex duct.
To avoid overpaying, get a written scope that specifies each repair, the materials, and the total. Beware of per-vent pricing or teaser rates that balloon once the crew is on site. CleanRun delivers one flat price per system, agreed before work starts, with no per-vent add-ons. Our free estimate includes the pressure test and leak detection; you pay nothing to learn what’s actually wrong.

Duct repair and sealing fixes the physical structure of your ductwork, closing gaps, reconnecting separated joints, and replacing damaged sections, while duct cleaning removes debris from the interior surfaces.
