Our Duct Repair & Sealing Services in Old Fig Garden
Duct Sealing
Most Old Fig Garden homes lose 20-30% of conditioned air through leaks before it ever reaches the register. In these 1920s-1940s houses, the problem is worse because ductwork was retrofitted decades after construction, often with unsealed transitions where original gravity furnace remnants meet newer forced-air sections. We seal with professional-grade mastic, not duct tape. Mastic stays flexible, won’t dry out in Fresno’s heat, and properly fills the gaps at mismatched gauge junctions. A typical whole-system seal in Old Fig Garden runs $450-$850 depending on access and linear footage.
Flex Duct Repair
Flex duct in Old Fig Garden attics doesn’t age well. The material degrades, sags, and disconnects at junction points - especially where it’s been resting directly on blown-in insulation added during energy retrofits. In a Spanish Colonial Revival on N Van Ness Boulevard, we discovered decades-old flex duct in exactly this condition, with insulation fibers clogging every register. We replaced the compromised sections with new insulated flex duct, sealed all connections with mastic, and installed an Aprilaire whole-house air cleaner to mitigate Valley particulate intake. Single flex duct section repair in Old Fig Garden typically costs $180-$340; multiple runs or full replacement runs $650-$1,200.
Metal Duct Repair
Some Old Fig Garden homes still have original galvanized metal ductwork from mid-century conversions, or rigid trunk lines that have corroded at seams. We patch, replace sections, or transition to modern flex where appropriate. Metal repair requires precise gauge matching - something our technicians verify on-site. Expect $320-$580 for most metal duct repairs in this area.
Duct Insulation
Fresno’s Central Valley summers punish uninsulated or degraded ductwork. When attic temperatures hit 140°F, poorly insulated ducts warm your cooled air before it reaches the vent. In Old Fig Garden, we regularly find original insulation crumbled to dust, or worse, insulation that has migrated into the duct interior through disconnected seams. Proper re-insulation with R-6 or R-8 wrap, plus sealing, runs $380-$720 for typical systems here.

Common Duct Repair & Sealing Problems We See in Old Fig Garden Homes
- Almond-harvest chaff and valley smog particulates accumulate in long, snaking attic duct runs, overwhelming standard filters and causing premature system failures. Fresno’s San Joaquin Valley air basin ranks among the nation’s worst for particulate pollution, and Old Fig Garden’s extended duct networks act like collection systems.
- Disconnected flex-duct junctions at transition points, often hidden under insulation, leak conditioned air and pull in attic debris, exacerbating indoor air quality issues. These disconnections are invisible without camera inspection.
- Mismatched gauges where newer duct sections join original gravity furnace remnants create pressure imbalances and persistent leaks at unsealed transitions. Standard tape repairs fail here; only mastic sealant properly bridges the gap.
- Insulation migration into duct interiors - a pattern we see almost exclusively in Old Fig Garden’s retrofitted estate homes. Blown-in insulation works its way into disconnected seams and shows up as fine gray fibrous debris at every register, a problem rarely seen in Fresno’s postwar tracts to the east.

FAQs - Duct Repair & Sealing in Old Fig Garden
Gray fibrous debris at your registers almost always means blown-in attic insulation has migrated into your ductwork through disconnected seams. In Old Fig Garden’s 1920s-1940s homes, flex duct sections often rest directly on insulation added during energy retrofits, and the material works its way inside over years of system cycling. Standard duct cleaning removes surface debris but won’t fix the underlying disconnection. We camera-inspect to locate the breach, reseat or replace the affected duct, seal with mastic, and verify the repair. Call (855) 401-6006 for a free inspection - estimates are free.
Repair is usually the smarter choice for Old Fig Garden Craftsman homes if the metal trunk lines are structurally sound. Original galvanized steel from this era is often heavier-gauge than modern equivalents and worth preserving. We typically replace degraded flex branch lines, seal all transitions with mastic, and add proper insulation. Full replacement runs $2,800-$4,500; targeted repair with sealing usually costs $650-$1,400 and addresses the actual failure points. We’ll show you camera footage of your specific system and recommend accordingly. Call (855) 401-6006 for a free second opinion on any replacement quote you’ve received.
The dense tule fog that blankets the Central Valley from November through February keeps Old Fig Garden residents running recirculating indoor air for weeks at a stretch, accelerating duct contamination cycles significantly. With windows sealed and systems on continuous recirculate, any existing leaks pull concentrated attic debris into your breathing air, and humidity differentials can degrade mastic seals that were improperly applied. We inspect seal integrity before fog season and repair compromised areas so your system isn’t recycling contaminants all winter. Call (855) 401-6006 to schedule pre-season inspection - our $89 Seasonal Tune-Up includes leak detection.
Yes, proper mastic sealing significantly reduces agricultural dust and almond-harvest chaff infiltration, though it’s one part of a two-part solution. Sealing the duct envelope stops your system from pulling unfiltered attic air through leaks. Pairing that with upgraded filtration - we often recommend Aprilaire whole-house air cleaners for Old Fig Garden’s particulate load - addresses what enters through normal return air. Most homeowners notice reduced dust accumulation and odor within one to two weeks of sealing. Whole-system sealing in Old Fig Garden runs $450-$850. Call (855) 401-6006 for an exact quote - estimates are free.
Signs of failed duct insulation include rooms that never reach set temperature, condensation on duct surfaces in the attic, and energy bills that spike during Fresno’s July-August heat despite normal usage. In Old Fig Garden, we also see insulation that has compressed, shifted, or migrated into duct interiors through age and vibration. We verify insulation condition during our camera inspection and recommend R-6 or R-8 replacement where degraded. Typical re-insulation with sealing runs $380-$720. Call (855) 401-6006 - we’ll show you exactly what your attic ductwork looks like and whether insulation is the culprit.
