Our Duct Repair & Sealing Services in Arlington

Duct Sealing
Most Arlington homes we inspect have leaks at the plenum, trunk seams, or register boots that lose 20-30% of conditioned air into the attic before it ever reaches the room. Our duct sealing process starts with a static pressure test and smoke-stick mapping to find every gap, then seals each joint with mastic sealant rated for North Texas attic conditions. In the 1970s tract blocks off Arkansas Lane in central Arlington, our tech opened a return chase and found the original grey fiberglass duct board delaminating at every seam, shedding glass microfibers straight into the blower motor intake. We ran camera inspection through the flex runs, found two plenum joints pulled loose by slab movement, then rebuilt the transitions with mastic sealant and Guardsman flex collars before sealing the whole trunk under negative pressure. Post-repair static pressure dropped and the homeowner stopped seeing dust streaks on the registers. Sealing a typical Arlington system runs $280-$550.

Flex Duct Repair
Arlington’s early-generation flex duct, common in post-Six Flags boom construction from 1965 through the mid-1980s, has an outer wrap that degrades after decades in 140-160°F attics. Once that wrap fails, attic insulation fibers, rodent debris, and mold spores pull straight into your air stream. We replace damaged flex runs with professional-grade material, secure plenum connections with mechanical fasteners and mastic, and photograph every connection before closing the chase. Flex duct repair on a single run in Arlington typically runs $180-$340; multiple runs or plenum rebuilds range $450-$780.

Metal Duct Repair
Some Arlington homes, particularly those built during the 1960s and early 1970s before flex duct dominated, still have galvanized metal trunk lines. These corrode at seams and can separate at collars after years of vibration and thermal expansion. We cut out damaged sections, fabricate replacement pieces on site, and seal with mastic and foil tape rated for permanent adhesion. Metal duct repair in Arlington generally runs $320-$650 depending on access and extent of corrosion.

Duct Insulation
When Arlington’s attic heat has cooked the original insulation off your duct board or flex runs, we re-wrap with formaldehyde-free insulation and vapor barrier, sealed at every seam. This matters in Arlington more than in milder climates. Your attic is a 160-degree oven for four months a year. Duct insulation replacement on a typical Arlington system runs $380-$720.

Common Duct Repair & Sealing Problems We See in Arlington Homes

- Original grey fiberglass duct board delaminating at seams. In south and central Arlington neighborhoods built between 1972 and 1984, technicians frequently find the original grey fiberglass duct board still in place, now shedding glass microfibers into the air stream after decades of thermal stress in superhot attics combined with foundation movement from the local clay soil.
- Flex duct joints pulled loose at plenums. Arlington’s Blackland Prairie “black gumbo” clay swells and shrinks under every slab-on-grade tract home, and that foundation micro-shift cracks duct board seams and pulls flex duct joints loose, venting conditioned air into the attic and pulling attic debris back into the living space.
- Degraded flex duct outer wrap letting attic contamination into the system. Early-generation flex duct outer wrap breaks down after years in North Texas heat, exposing the inner liner to abrasion and creating entry points for insulation fibers, mold spores, and rodent debris.
- Thermal cycling widening duct joint gaps over time. Arlington’s HVAC systems run 8-9 months under heavy load, and the repeated expansion and contraction of duct materials in 140-160°F attics gradually opens gaps at every seam and collar that mastic sealant applied years ago can no longer hold.

FAQs - Duct Repair & Sealing in Arlington

The Blackland Prairie expansive clay under Arlington’s slab-on-grade tract homes swells with spring rain and contracts in summer drought, causing constant micro-shifts in the foundation. That movement pulls flex duct joints loose at plenums and cracks duct board seams, so disconnection is a soil-geology problem, not just age. We see it most in the 1972-1984 construction south of I-30 and through central Arlington. Call (469) 405-6133 for a camera inspection and written repair scope.
It means the original duct board has reached end of life. The fiberglass layers separate and release microfibers into your air stream, where they pass through standard filters and deposit as fine dust on registers and furniture. In Arlington, this is accelerated by decades of 140-160°F attic thermal cycling. We replace failed duct board with modern flex or metal, sealed with mastic, and photograph the before and after on every run. Replacement typically runs $890-$1,400 for a whole trunk.
Sealing materials must be rated for the thermal stress. Standard tape fails in Arlington attics. We use mastic sealant and mechanical fasteners rated for continuous exposure to high temperature, and we schedule extensive sealing work during morning hours when attic temperatures allow proper cure times. The same heat that degraded your original ducts will degrade improper repairs. Call (469) 405-6133 and we’ll specify the materials in writing.
Yes. The high renter population near campus concentrates older apartment complexes with heavily contaminated duct systems rarely cleaned between tenants, and with shared plenums that make isolated sealing difficult. We coordinate with property management for access to common mechanical areas and document each unit’s duct condition separately. Single-family homes in Arlington typically have simpler access but more extensive foundation-related separation. Either way, the written price comes before any work starts.
Signs include dust streaks on ceiling registers, uneven temperatures room-to-room, higher-than-expected electric bills in summer, and musty odors when the system cycles. The definitive check is a static pressure test and smoke-stick inspection, which we perform during every evaluation. In Arlington, foundation movement makes attic pull-back especially common at return plenums. We find it, photograph it, and put the repair scope in writing before any sealing begins. Call (469) 405-6133 for a free evaluation.
