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 Elgin since the first Harvest Ridge foundations were poured, and we’ve learned something that surprises most homeowners: a house built in 2019 often needs duct attention sooner than a 1970s ranch. The spec-home boom here produced thousands of homes whose duct systems were rushed through installation, sealed with builder-minimum mastic, and handed over with construction debris still inside. If your home is one of Elgin’s newer builds, you’re probably not imagining that smell every time the AC kicks on.
Our Duct Repair & Sealing crews serve Elgin with the H.A.V.E.N. Standard in force on every job: background-checked technicians, written pricing before work begins, and a Documented Photo Record of every duct run delivered when we leave. Haven Standard Clause 1 means the price you agree to is the price you pay. No per-vent add-ons, no “while we’re here” upsells.
Why CleanRun Air Duct Cleaning Round Rock Is Elgin’s Preferred Duct Repair & Sealing Company
We’ve served more than 52,000 homes since 2013, and Elgin’s growth curve has put it among our most frequent destinations in the last five years. The pattern we see here is distinct: not aging duct systems failing from time, but new systems failing from how they were built and what was left inside them.
Our reviews from Elgin customers consistently mention two things: the before-and-after photos they didn’t expect to receive, and the written price that didn’t change. One Harvest Ridge homeowner noted that our technician found a detached flex boot her builder’s warranty crew had missed twice. Another in a nearby subdivision said the photo record showed her exactly why her utility bills had climbed 30% in two years.
Dispatch to Elgin runs through our Austin office, with crews carrying Rotobrush and Nikro equipment plus Guardsman sealants stocked for same-visit repairs. We know the difference between Elgin’s historic-core ranch homes with original metal duct and the ring of 2010s-2020s subdivisions with pinched flex runs and minimal mastic. That local housing knowledge changes what we bring to the job and what we expect to find.
Tomas Reyes, who leads CleanRun, established the Documented Photo Record practice in 2013 and has maintained it on every single job since. The H.A.V.E.N. Standard carries his name on every written guarantee.
Our Duct Repair & Sealing Services in Elgin
Duct Sealing with Mastic Sealant
Elgin’s Blackland Prairie clay soils shift seasonally with moisture, and that movement travels through slab foundations into flex duct boot connections. We apply Guardsman mastic sealant at every connection point, not just the plenum, because we’ve learned that builder-minimum sealing fails here in ways it doesn’t in areas with more stable soils. A typical mastic re-sealing job in Elgin runs $340-$520 for a single-system home.
Flex Duct Repair
The flex duct in Elgin’s newer subdivisions was often installed with tight bends and inadequate support, then left unchanged through construction and the warranty period. We replace collapsed or torn flex runs with properly sized and supported new material, and we photograph the damage before touching it. Flex duct repair in Elgin typically costs $180-$340 per run, with most homes needing 1-3 runs addressed.
Metal Duct Repair
Elgin’s older homes near the historic core still carry original galvanized metal duct from the 1960s through 1980s. We patch corroded sections, re-seal joints with mastic, and replace damaged plenum connections. Metal duct repair runs higher than flex work, typically $420-$680, because it often involves custom-fabricated transitions.
Duct Insulation Replacement
Attic temperatures in Elgin hit 140°F in July, and degraded duct insulation costs you conditioned air before it reaches the register. We replace torn or compressed insulation with new R-8 wrap, sealed at every seam. Insulation replacement on a full system in Elgin runs $480-$760.

Common Duct Repair & Sealing Problems We See in Elgin Homes
- Detached flex duct boots from slab movement. Elgin’s expansive clay soils shift enough seasonally that boot connections pull partially loose, pumping conditioned air into the attic. We find this in Harvest Ridge and similar subdivisions on nearly every camera inspection. The homeowner usually notices first as uneven temperatures between rooms or a sudden spike in summer electric bills.
- Construction debris still circulating 3-12 years after build. Drywall dust and insulation fragments from the original construction were never removed at handover. The original filter was often left unchanged through the entire warranty period. When we run a camera, the supply ducts look like a jobsite that was never cleaned up.
- Loblolly pine pollen loading return ducts every spring. Elgin sits on the western edge of the Lost Pines ecosystem, and that pollen doesn’t reach Pflugerville or Round Rock. It mats down with Blackland Prairie dust, restricting airflow and forcing the blower motor to run hotter. We’ve pulled return ducts here that were 40% blocked by this combination.
- Pinched flex runs off the air handler. Builder-minimum installations in Elgin’s spec homes often feature flex duct pulled too tight around corners, creating kinks that restrict airflow and raise static pressure. The system runs longer to compensate, wearing components faster and driving up utility costs.

FAQs - Duct Repair & Sealing in Elgin
Yes. In Elgin’s 2010s-2020s spec homes, we routinely find drywall dust and insulation debris still circulating 3 to 12 years after build. The original filter was often never changed during the construction or warranty period, so that debris never had a clear path out of the system. We got a call from a homeowner in Harvest Ridge whose 2019-built home had never had its ducts touched - her words were that the air “smelled like a construction site” every time the AC kicked on. Our tech ran a camera inspection and found drywall dust caked inside the supply and return ducts, plus a pinched flex run off the air handler that the builder had mastic-sealed at the plenum but not at the boot. After source removal with agitation tools under negative pressure and new mastic at the boot connections, she said the smell was gone within a day. Call (737) 259-5752 for a camera inspection and written estimate.
Elgin’s Blackland Prairie clay soils expand and contract seasonally with moisture changes, shifting slab foundations enough to pull flex duct boot connections loose. Round Rock sits on more stable Edwards Plateau limestone soils that don’t move the same way. This is a local soil condition, not a construction defect you can blame on one builder. We reattach boots with mechanical supports plus fresh mastic at every connection, not just the plenum, to account for this ongoing movement. Call (737) 259-5752 and we’ll show you the detachment on camera before quoting repair.
Yes. Elgin sits on the western fringe of Bastrop County’s Lost Pines ecosystem, and loblolly pine pollen loads the return ducts here every spring in a way that Pflugerville and Round Rock residents simply don’t experience. That pollen is large, sticky, and mats down with Blackland Prairie dust to form dense layers on duct walls and at filter frames. We’ve measured return ducts in Elgin subdivisions that were 30-40% airflow-restricted by this combination. The effect is real, local, and measurable. Call (737) 259-5752 for a camera inspection that will show you exactly what’s inside.
Yes, and in Elgin’s newer homes it’s often the primary problem. Detached flex boots and builder-minimum mastic sealing pump conditioned air directly into the attic, so your system never reaches setpoint and runs continuously from May through September. We’ve documented cases where sealing detached boots and re-applying mastic dropped runtime by 25-35%. The nonstop running you’re seeing is your system’s attempt to compensate for air that’s not reaching the rooms. Call (737) 259-5752 for leak detection and a written repair price.
Ask specifically whether they follow NADCA Standard 2021 for Assessment, Cleaning, and Restoration of HVAC Systems, and whether they provide a written scope before work begins. At CleanRun, we exceed that standard with our own H.A.V.E.N. Standard, which adds Haven Standard Clause 1 (written price before work), Haven Standard Clause 3 (verified, background-checked crews identified by name), and the Documented Photo Record as a standard deliverable, not an extra. Any company that won’t put their standards and pricing in writing before starting should be questioned. Call (737) 259-5752 and we’ll send you our standard in advance of any visit.
