Fast, Reliable Duct Repair & Sealing Across Richland Hills
Duct repair and sealing in Richland Hills typically costs $180–$650 depending on whether we’re sealing accessible joints with mastic or replacing collapsed flex duct in a 1960s attic, and most jobs are completed in a single visit. If your ranch home on Dickson Drive or near Loop 820 has weak airflow, dust pouring from vents, or rooms that won’t hold temperature, the culprit is usually decades-old ductwork that’s been cooking in a 140°F attic since the Johnson administration. We’re Summit Air Duct Cleaning Service Texas, and our Duct Repair & Sealing team serves Richland Hills with the same equipment commercial restoration contractors use — Rotobrush and Nikro systems, not shop vacs from the hardware store. Call (844) 886-2161 for a free estimate; we’ll inspect your system and show you exactly what’s failing before we touch a tool.

Why Summit Air Duct Cleaning Service Texas Is Richland Hills’s Preferred Duct Repair & Sealing Company
We’ve worked in enough Richland Hills attics to know the difference between a 1954 slab ranch on Haltom Road and a 1972 split-level near the Watauga border — and how each era of construction fails differently. Our 4.9-star average across 775 verified customer reviews includes dozens from Richland Hills homeowners who specifically mention Michael Brown showing up as the lead technician, not a subcontracted crew they’d never met. That matters in a city where most houses were built before 1975 and you need someone who can read galvanized trunkwork like a map.
Response time to Richland Hills runs same-day or next-day for standard calls, because we’re already working the Mid-Cities corridor between North Richland Hills and Haltom City. We don’t dispatch from downtown Fort Worth or Dallas and hope to hit your window. Michael Brown has spent eight years focused exclusively on air duct and HVAC cleaning — not installation, not general repair, not carpet cleaning on the side. When you hire Summit, the owner shows up and does the work. Equipment built for this job. Eight years focused on one trade.
Our Duct Repair & Sealing Services in Richland Hills
Duct Sealing
Most Richland Hills homes we enter have never had their ducts professionally sealed. The original builders taped joints with cloth-backed adhesive that turns to powder after twenty years in a hot attic. We remove failed tape, clean the mating surfaces, and seal every joint and seam with mastic sealant — a thick, fiber-reinforced compound that remains flexible at temperature extremes. For a typical 1,400-square-foot ranch in the 76180 ZIP, full duct sealing runs $350–$550 and typically improves system efficiency 15–25 percent. Homes near Loop 820 see additional benefit: sealed ducts stop drawing in highway particulate through negative pressure at worn joints.
Flex Duct Repair
The 1970s additions and garage conversions common in Richland Hills often used early flex-duct that simply collapses after fifty years. We replace pinched or torn flex with modern R-8 insulated duct, properly supported to prevent sagging, and sealed with mastic at every connection. A single flex duct run replacement in Richland Hills typically costs $180–$320. We see this failure constantly in the older neighborhoods between Boulevard 26 and Dickson Drive, where original flex has compressed to half its diameter.
Metal Duct Repair
Galvanized steel trunkwork from the 1950s and 1960s doesn’t fail catastrophically — it rusts at seams, separates at joints, and develops pinholes where decades of condensation collected. We repair salvageable metal duct with custom-fabricated patches and professional-grade sealants. When a trunk is too far gone, we fabricate replacement sections on-site. Metal duct repair in Richland Hills ranges $280–$480 for standard trunk sections. On a 1965 ranch on Dickson Drive, we found the original galvanized supply trunk had gaping seams pulling in attic dust and fiberglass. We cleaned the system with Rotobrush, then sealed every joint with mastic and wrapped the trunk in R-8 insulation, restoring static pressure and eliminating the musty odor.
Duct Insulation
Original duct insulation in Richland Hills attics has endured something no engineer in 1960 fully anticipated: fifteen thousand consecutive days of 140°F summer heat. Fiberglass wrap degrades, compresses, and sheds fibers into the airstream. We strip failed insulation and install new R-8 or R-6 wrap depending on space constraints, sealing the vapor barrier completely. Full trunk insulation for a typical Richland Hills ranch runs $400–$650. This is especially critical for homes whose ducts run through unconditioned attic space — which is nearly every house in this city.

Trusted Brands We Service in Richland Hills
We stock parts and materials from Honeywell, Aprilaire, and Guardsman for Richland Hills jobs, which means no waiting on shipping when your system needs a specific register boot, damper, or filtration upgrade. Our Rotobrush and Nikro equipment is the same spec used by commercial restoration contractors — not consumer-grade tools that leave debris behind. If your 1960s ranch needs a modern Aprilaire media air cleaner installed on a decades-old plenum, we’ve done that exact job in Richland Hills before and have the fittings on the truck.
Common Duct Repair & Sealing Problems We See in Richland Hills Homes
- Duct liner deterioration from decades of 140°F attic heat causes fiber shedding that bypasses cheap filter slots. We regularly find degraded fiberglass lining in Richland Hills attics that’s literally crumbling into the airstream. Homeowners report “dust that never stops” — it’s not dust, it’s forty-year-old duct liner finally giving up.
- Tape failures at joints under slab foundations create hidden leaks that draw in crawlspace moisture and allergens. Richland Hills’s slab construction means some duct runs sit in or near the foundation perimeter. Failed tape at these joints pulls in musty air and, in some cases, soil gas. We seal these with mastic and mechanical fasteners that outlast any adhesive.
- Original flex-duct in 1970s additions collapses due to age, pinching airflow and causing uneven temperatures. The back bedroom that’s “always hot” or the garage conversion that “never cools” — we trace these complaints to collapsed flex in about sixty percent of Richland Hills calls. The duct isn’t broken; it’s just suffocated.
- Negative pressure from worn joints pulls highway particulate and attic insulation fibers into supply air. This is the distinctive pattern we see in Richland Hills homes near Loop 820. Diesel particulate, tire dust, and degraded fiberglass enter the living space through gaps that should have been sealed decades ago. The homeowner smells exhaust or sees unusual dust; the cause is duct leakage, not a failing HVAC unit.

FAQs — Duct Repair & Sealing in Richland Hills
Yes — in most cases we seal 1960s metal trunkwork from inside the attic without removing drywall or soffits. We access joints through existing attic hatches, clean surfaces with wire brushes, and apply mastic with extension tools that reach deep into truss bays. The only time we need to open a ceiling is when a duct has fully detached from a register boot and dropped into a wall cavity. Call (844) 886-2161 and we’ll inspect your access points during a free estimate.
Yes — duct sealing is often the most effective solution for exhaust odor in homes near Loop 820. The negative pressure your HVAC system creates pulls outside air through any gap in the ductwork; sealing those gaps with mastic stops the infiltration at its source. We’ve measured particulate levels drop significantly after sealing in Richland Hills homes along the southern edge. We can test your system’s pressure balance and show you exactly where the leaks are.
Failed duct insulation shows three clear signs: visible compression or gaps in the fiberglass wrap, condensation or sweating on the metal duct surface beneath, and rooms that are consistently 5–10 degrees off from the thermostat setting. In Richland Hills’s extreme attic heat, insulation degradation accelerates after about twenty-five years — meaning most original insulation is well past functional. We inspect insulation condition during every duct sealing estimate and photograph what we find.
Duct tape is a cloth-backed adhesive that fails in heat; mastic sealant is a thick, fiber-reinforced compound that remains permanently flexible and is rated for HVAC temperature cycles. We remove old duct tape entirely — it’s usually crumbling anyway — and seal joints with mastic applied by brush or gloved hand. Mastic costs more in material and labor, but in a Richland Hills attic that hits 140°F, it’s the only sealant we trust to last. The difference is permanent repair versus temporary patch.
We do, but with specific protocols: asbestos-containing insulation requires containment, wet removal methods, and proper disposal per Tarrant County regulations. We do not disturb asbestos-wrap without establishing a containment zone first. If your Richland Hills home has the white corrugated cardboard-style insulation common on 1950s–1960s ductwork, we’ll test or assume asbestos and quote accordingly. The sealing work itself proceeds normally once the wrap is safely addressed. Call (844) 886-2161 to discuss your specific situation — estimates are free and we’ll flag any asbestos concerns during inspection.
