Why Nova Air Duct Cleaning Service Austin Is Georgetown’s Preferred Duct Repair & Sealing Company
More than 1,255 homeowners have reviewed us, and that 4.9-star average reflects the kind of accountability you get when Douglas Ross, the owner, is also the lead technician on your job. In Georgetown, that matters — especially when we’re crawling through tight attic spaces in newer subdivisions along West University Avenue or working around the unique duct layouts in homes near the 1800’s Stone Building.
Our response time to Georgetown is consistently under an hour for standard calls, and we carry the professional-grade Rotobrush and Nikro equipment needed to handle Georgetown’s specific challenges: pre-cleaning cedar pollen residue before mastic application, and extracting construction dust from flex duct runs that builders never cleared. We don’t just patch and leave. From cleaning to repair to sanitizing, we handle the full scope — something single-service competitors can’t match.
Georgetown’s growth has been explosive. Subdivisions like Escalera Ranch, Churchill Farms North, and Cimarron Hills are filled with homes built so quickly that duct systems went from construction site to occupied without proper cleaning. We know what to look for in these houses. We’ve been there.
Our Duct Repair & Sealing Services in Georgetown
Duct Sealing
Leaky ductwork in Georgetown homes wastes 20–30% of conditioned air before it reaches your rooms. In the Cimarron Hills subdivision, we sealed a sagging flex duct run that had been installed during the 2019 build but never cleared of drywall dust; using Rotobrush agitation and mastic sealant, we re-bonded the flex duct joints and restored airflow to the master bedroom, eliminating the 10°F temperature differential the homeowner had reported. We seal with mastic, foil tape, and aerosol-based methods depending on access and duct type — critical in Georgetown’s tight attic spaces where summer heat pushes 140°F.
Flex Duct Repair
Flex duct dominates Georgetown’s housing stock, especially in master-planned communities built between 2005 and 2020. The problem? Attic-run flex sags over time, pools debris, and develops tears at connection points. In townhomes along Pickle Parkway, tight crawl spaces make full replacement impossible without pulling back insulation, so partial repair with reinforced liner and proper support straps is often the right call. We inspect interior liners with camera systems — damage you can’t see from the outside is common after years of cedar pollen and caliche dust abrasion.
Metal Duct Repair
Older homes near the Georgetown Square and pre-1960s structures off TX 29 West often have galvanized steel or aluminum ductwork that’s corroded at seams or separated at joints. Metal repair requires different techniques: spot welding, slip-joint reconnection, and specialized sealants that bond to oxidized surfaces. We’ve worked on these systems enough to know when repair makes sense versus when replacement sections are the smarter long-term play.
Duct Insulation
Georgetown’s May–September cooling season runs hard. Uninsulated or degraded duct insulation in your attic means you’re paying to cool 140-degree metal. We replace fiberglass wrap and install reflective barrier insulation where appropriate, focusing on the supply runs that matter most. In newer homes near Churchill Farms North, we’ve found builder-grade insulation already compressed or moisture-damaged from condensation — a hidden efficiency killer.
Mastic Sealant Application
Mastic is our go-to for lasting seals in Georgetown’s pollen-heavy environment. Unlike tape, mastic remains flexible and creates a true airtight bond — but only when applied to clean surfaces. Cedar pollen residue from December–February clings to mastic and tape adhesives unless pre-cleaned with a HEPA vac, leading to re-leaks within one season. We pre-clean every joint with Rotobrush agitation and HEPA extraction before mastic goes on. It’s extra time. It’s the only way it lasts.
Air Leak Repair
Air leaks at register boots, plenum connections, and damper locations are the silent efficiency killers we find in Georgetown homes. New homeowners in Churchill Farms North are often unaware that original construction dust — drywall compound, wood shavings, caulk particulate — still cakes their register boots, causing sealant to fail on dirty surfaces. We pressure-test, locate, and repair these leaks with methods matched to the contamination level and duct material.

Trusted Brands We Service in Georgetown
We work with Honeywell, Aprilaire, and Abatement Technologies components daily — air cleaners, UV systems, and filtration upgrades that integrate with repaired ductwork. For Georgetown customers, that means we stock common parts and can complete multi-component jobs without waiting on shipping. If your duct repair reveals a failing Aprilaire media filter housing or a Honeywell bypass humidifier with cracked connections, we handle it in the same visit. Eight years focused on one trade means we’ve seen how these brands age in Central Texas conditions.
Common Duct Repair & Sealing Problems We See in Georgetown Homes
- Construction dust caking in “new” homes. In subdivisions built along the SH-195 and Pickle Parkway corridors within the last five years, attic flex duct runs commonly show visible drywall dust caking at register boots and directional bends — a direct artifact of framing-era construction never remediated before move-in. Homeowners assume a 2022 build means clean ducts. They’re wrong.
- Cedar pollen overwhelming standard seals. On the Balcones Escarpment, Georgetown’s dense Ashe juniper (mountain cedar) creates the highest cedar pollen counts in Central Texas from December through February, overwhelming HVAC filters and coating duct interiors with a sticky, fine particulate that requires aggressive sealing to prevent re-entry. Standard tape seals fail. Mastic, properly pre-cleaned, doesn’t.
- Sagging flex duct in summer attic heat. Georgetown’s attic temperatures degrade flex duct support straps and cause liner separation at bends. We regularly find 8–12 foot sagging runs in homes off Purple Heart Trail that have lost 40% of design airflow to friction and pooling.
- Tight attic access limiting repair options. Townhomes and smaller lots in newer Georgetown developments often have scuttle holes or limited gable access that makes full duct replacement impractical. We design repair strategies — sectional replacement, interior liner patching, strategic mastic application — that work within real spatial constraints.
Pricing for Duct Repair & Sealing in Georgetown, TX
| Service | Typical Range in Georgetown |

FAQs — Duct Repair & Sealing in Georgetown
Because builders rarely clean duct systems after construction, and the drywall compound, wood shavings, and caulk particulate left inside prevent sealants from bonding properly. In Georgetown’s rapid-growth subdivisions, speed of completion often overrides duct cleanliness — we’ve found 2020–2023 builds with register boots caked in construction debris that was never extracted before move-in. Call (833) 315-4216 for a free inspection and we’ll show you what’s actually in your “new” system.
Yes — proper sealing with pre-cleaned surfaces and quality mastic significantly reduces pollen infiltration through duct leaks, though it works best paired with upgraded filtration. Georgetown’s mountain cedar pollen concentrations from December through February far exceed those in cities just 30–40 miles east on the Blackland Prairie, so every gap in your duct system is an entry point for particulate that bypasses your filter entirely. Call (833) 315-4216 to discuss sealing plus filtration options.
Yes, we repair sagging flex duct by re-supporting the run, patching or replacing damaged liner sections, and resealing connections with mastic — but we also inspect for the underlying cause, which in Georgetown often includes construction debris weight and degraded support straps from attic heat cycling. A quick re-support without debris removal just sags again. Call (833) 315-4216 for an estimate — we’ll show you camera footage of what’s inside.
Yes — pre-1960s structures near the downtown square typically have rigid metal ductwork, non-standard sizing, or mixed materials that require different repair techniques than modern flex systems. We’ve worked on these layouts enough to fabricate transitions, repair corroded galvanized seams, and adapt modern sealing methods to older construction. The historic core’s tight crawl spaces and original framing also affect access strategy. Call (833) 315-4216 to discuss your specific home.
Ideally within the first 12–18 months, after construction dust has had time to settle and initial HVAC cycling has revealed where builder-grade seals are failing. In Georgetown’s newest subdivisions, we recommend duct inspection and cleaning before sealing — applying mastic over construction debris is a waste of money. The seal fails within a season. Call (833) 315-4216 to schedule a pre-sealing inspection and cleaning.
