We’re not generalist HVAC contractors who occasionally touch ductwork. Our Duct Repair & Sealing team focuses specifically on air pathways — cleaning, repairing, sealing, and sanitizing — with equipment built for this job. Owner Michael Brown shows up and does the work himself, bringing eight years of dedicated specialization and professional-grade Rotobrush and Nikro systems to every Addison job.
Why Summit Air Duct Cleaning Service Texas Is Addison’s Preferred Duct Repair & Sealing Company
Addison’s unique housing stock demands a different kind of duct specialist. Nearly every residential building here is a 1970s-to-early-2000s apartment complex or mid-rise condo — high-turnover rentals with aging flex ductwork that has cycled through dozens of tenants without proper maintenance. We’ve worked in buildings along Prestonwood Boulevard, in the Addison Circle district, and throughout the Marsh Lane corridor. We know the tight attic chases, the shared return plenums, and the parking constraints that come with servicing third-floor units in dense developments.
Our reputation here is built on specifics, not slogans. 775 customers have left verified reviews averaging 4.9 stars — a volume that rules out cherry-picking and reflects consistent, repeatable results. Addison property managers and homeowners associations call us back because Michael Brown personally handles the technical work, makes on-site decisions about repair scope, and doesn’t hand the job off to a rotating crew. Eight years focused on one trade means we’ve seen the failure patterns that repeat in Addison’s building stock and know how to fix them without unnecessary upsells.
Response time matters in summer heat that keeps AC systems running 16+ hours daily from May through September. We carry mastic sealant, fiberglass mesh tape, and flex duct replacement sections sized for the compact chases common in Addison’s older mid-rises — no waiting on parts, no return trips.
Our Duct Repair & Sealing Services in Addison
Duct Sealing
Air leaks in Addison apartment ductwork waste 20–30% of conditioned air before it reaches your registers. We seal supply and return runs with mastic sealant and fiberglass mesh tape — the combination that actually lasts in North Texas heat, not foil tape that peels within two summers. In Addison’s shared chases, we pay special attention to return-side sealing; skipping this lets grease-laden air from adjacent units infiltrate your system. A typical apartment duct sealing job in Addison runs $280–$480.
Flex Duct Repair
Flex duct in Addison’s 1980s and 1990s buildings has often collapsed, torn at support points, or separated from boots after decades of vibration and tenant turnover. We replace damaged sections with properly supported flex duct rated for the static pressure of your system — critical in tight attic chases where sagging creates airflow-kinking pinch points. We sealed a flex duct tear in a third-floor condo at the Villas at Addison Circle, where the apartment’s supply registers had a noticeable greasy residue from nearby restaurant exhaust. Our tech used mastic sealant and fiberglass mesh tape on the torn flex, then applied a Rotobrush agitation to clean the residual oil film before resealing the chase. Flex duct repairs in Addison typically cost $180–$340.
Metal Duct Repair
Older Addison buildings and some commercial conversions have galvanized steel trunk lines that corrode at seams or crack from thermal expansion after 40+ years of continuous summer cycling. We patch metal ducts with proper sheet metal screws and sealed joints — not duct tape — then coat with mastic for a permanent repair. Metal duct repair in Addison runs $320–$550 depending on accessibility and extent of damage.
Duct Insulation & Mastic Sealant
Condensation inside poorly insulated ductwork is a real concern in Addison’s humid summer months, particularly in buildings where AC runs nearly nonstop. We reinsulate accessible duct sections with foil-faced fiberglass wrap and apply mastic sealant at all joints — creating a vapor barrier that prevents moisture accumulation and the mold growth that follows. Mastic sealant fails to bond on oily duct surfaces near Belt Line Road unless degreased first; we account for this in our Addison protocol. Duct insulation work in Addison typically ranges from $380–$650.

Trusted Brands We Service in Addison
We stock parts and use equipment from manufacturers that commercial restoration contractors trust: Rotobrush agitation systems for breaking up adhered grease deposits, Nikro HEPA vacuums for contained debris removal, and Honeywell media filters for post-repair air quality improvement. For sealing materials, we source professional-grade mastic compounds and fiberglass mesh tape rated for the temperature cycling that Addison ductwork endures. We don’t use consumer-grade shop vacs or hardware-store foil tape — equipment built for this job produces repairs that survive North Texas summers. Parts availability means most Addison repairs are completed in a single visit without waiting on special orders.
Common Duct Repair & Sealing Problems We See in Addison Homes
- Grease-contaminated duct surfaces near Belt Line Road. Addison’s nationally recognized restaurant density — one of the highest per-capita concentrations in the United States — means residential HVAC intakes draw cooking grease vapor, smoke, and VOC particulates from nearby exhaust stacks. Technicians cleaning ducts in Addison apartment complexes near the Belt Line Road restaurant belt regularly find a faint oily film coating supply duct interiors, a contamination pattern essentially unseen in the single-family subdivisions of adjacent Carrollton or Farmers Branch. This residue prevents standard mastic sealant from bonding properly and requires degreasing pretreatment before any sealing work.
- Collapsed flex duct in tight attic chases. Addison’s residential stock is almost entirely apartment complexes and mid-rise condos built between the late 1970s and early 2000s. The compact attic and chase clearances in these buildings mean flex duct often lacks proper support spacing. After patching, improper support causes immediate re-collapse. We install additional support straps and rigid backing where space allows.
- Shared return pathways pulling contaminants between units. The dense multi-unit construction in Addison means shared air-handling chases and return pathways that accumulate contaminants from many occupants simultaneously. Air leak repairs that skip return-side sealing in these shared chases let grease-laden air from adjacent units infiltrate — we seal both supply and return sides as standard practice.
- Condensation damage in overworked summer systems. North Texas heat keeps Addison HVAC systems running nearly continuously from May through September, cycling dusty, pollen-heavy, and grease-particulate-laden air through ductwork for far more annual hours than systems in milder climates. Summer humidity combined with the heavy AC load creates condensation risks inside older apartment duct insulation, making mold growth a real secondary concern during cleaning inspections — one we flag and address before sealing.

FAQs — Duct Repair & Sealing in Addison
Addison’s restaurant corridor along Belt Line Road produces airborne grease vapor that infiltrates residential duct intakes, leaving an oily film inside supply ducts — a contamination pattern unseen in neighboring Carrollton or Farmers Branch. This residue prevents standard mastic sealant from bonding properly and requires degreasing with Rotobrush agitation before any sealing work can succeed. Call (844) 886-2161 if you’re noticing greasy vent covers — we’ll inspect and quote free.
Flex duct in 1980s Addison mid-rises commonly tears at support points, collapses in tight attic chases due to improper original installation, or separates from boots after decades of vibration and tenant turnover. Flex duct repairs in these tight attic chases collapse due to improper support after patching unless additional straps and rigid backing are installed. Typical repair cost in Addison runs $180–$340. Call for a free inspection.
Yes — shared chases in Addison’s dense multi-unit buildings require sealing of both supply and return sides, not just the obvious leaks.
