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.

Our Duct Repair & Sealing Services in Prosper
Duct Sealing
Prosper’s oversized homes - commonly 3,500 to 6,000+ square feet - contain extensive multi-zone duct networks with significantly more linear footage than typical Metroplex jobs. More joints mean more potential leakage points. We seal supply and return plenums, register boots, and longitudinal seams with mastic sealant rated for the temperature swings these attic systems experience. A typical duct sealing job in Prosper runs $340-$620 for a whole-system treatment. Every sealed joint is photographed before and after.
Flex Duct Repair
Flex duct dominates Prosper’s attic installations, and it fails differently here than in other markets. The Black Land Prairie clay beneath Prosper shifts seasonally with wet-dry cycles, creating subtle foundation movement that stresses flex-duct joints at collars and plenum connections. We’ve found separated runs in three-year-old homes in Lakes of La Crosse and Windsong Ranch. Repair involves reconnecting the failed joint, reinforcing with mechanical fasteners, and applying mastic sealant - not tape alone, which degrades in 140°F+ attic heat. Flex duct repair in Prosper typically ranges $180-$340 per run.
Metal Duct Repair
Some Prosper builds - particularly custom homes by Toll Brothers and David Weekley in higher-end subdivisions - use galvanized metal trunk lines with flex take-offs. Metal ducts don’t tear, but longitudinal seams can separate and corners can crack from thermal expansion stress in unconditioned attics. We repair with mechanical fastening and sealant rated for metal substrates. Metal duct repair in Prosper generally runs $260-$480 per section.
Duct Insulation
When flex-duct liner breaks down from sustained attic heat exposure, insulation value drops and the duct begins shedding particles into the airstream. In Prosper’s all-attic systems, this happens faster than homeowners expect. We replace degraded insulation with new flex duct or apply external insulation wraps where the duct body remains sound. Duct insulation work in Prosper typically costs $220-$560 depending on linear footage.

BeforeAfterTrusted Brands We Service in Prosper
Our Prosper trucks carry parts and sealants from Honeywell, Aprilaire, and Abatement Technologies - brands published so customers can verify specifications independently before agreeing to any work. We don’t use hardware-store consumables on duct systems that see continuous thermal stress. For mastic sealant applications in Prosper’s high-temperature attics, we specify products rated for the temperature range these spaces actually reach, not the ambient conditions downstairs.
Common Duct Repair & Sealing Problems We See in Prosper Homes
- Flex-duct joints separating from foundation movement. Prosper’s Black Land Prairie clay expands and contracts seasonally, stressing attic duct connections until they pull apart at collars. The homeowner calls for air quality concerns; we find a leak that has been pulling attic air into the system for months.
- Return plenums clogged with construction debris in homes under five years old. In actively developing Prosper corridors, finished homes border active grading and framing for two to three years after move-in. Return-air systems continuously pull fine silica dust and clay particulate from surrounding job sites, packing filter boxes and coating supply boots gray.
- Flex-duct liner baking and shedding in 140°F+ attics. Prosper’s oversized homes run longer duct networks through unconditioned attic space that routinely exceeds 140°F from May through September. The liner degrades faster than annual filter changes can signal.
- Drywall dust and insulation fragments locked in since finish-out. Production builders run HVAC during construction to speed drying and curing. That practice blows drywall mud powder, wood particles, and blown-insulation fragments deep into duct runs that are then sealed behind registers and never cleaned before handover.
Pricing for Duct Repair & Sealing in Prosper, TX

FAQs - Duct Repair & Sealing in Prosper
Because the builder ran HVAC during finish-out, blowing drywall dust, insulation fragments, and wood particles into duct runs that were then sealed behind registers without cleaning. In Prosper’s actively developing areas, surrounding construction sites added silica and clay particulate for two to three years after your move-in. The age of the house doesn’t match the condition of the ducts. Call (940) 290-8552 for a free inspection and written quote.
Fine silica dust and clay particulate from adjacent active construction sites enter through return-air grilles every time the system cycles, coating supply boots and clogging plenums. In Prosper’s developing corridors, this pattern is common in homes only three or four years old. The gray coating isn’t household dust; it’s construction-site particulate that entered continuously after occupancy. We document this with before-and-after photography on every job.
The expansive clay shifts seasonally with wet-dry cycles, creating subtle foundation movement that stresses flex-duct joints in attic systems. We’ve found separated collars in three-year-old homes where the movement pulled joints apart. This turns an air quality call into a discovered leak, and it’s specific to Prosper’s geology. Our repair includes reconnecting the run and applying mastic sealant rated for the thermal stress these attic systems see.
Signs pointing to sealing: uneven temperatures between rooms, higher-than-expected energy bills, or dust accumulation near registers despite regular filter changes. During our inspection, we pressurize the system and inspect joints with a camera. If we find separated collars or failed mastic, we quote sealing or repair separately from cleaning so you see exactly what each scope addresses. The written price covers only what you approve.
Post-construction duct cleaning with negative-pressure extraction and HEPA filtration before final HVAC startup. Protection of registers during drywall sanding and insulation blow-in. Verification that no construction debris remained in plenums or trunk lines. Most Prosper production builders skip these steps to maintain schedule. CleanRun’s documented photo record shows you what was actually left behind. Call (940) 290-8552 for a free estimate - we’ll show you what’s inside your ducts before quoting any work.
