Ryan Bell, our owner and lead technician, knows these homes inside and out: the shallow crawlspaces, the retrofitted ductwork from the 1960s and 70s, the way Fresno’s agricultural dust and fig tree pollen work their way into systems that were never designed for modern HVAC loads.

Our Duct Repair & Sealing Services in Old Fig Garden
Duct Sealing
Most Old Fig Garden homes lose 25–40% of conditioned air through leaks at plenum connections, junction boxes, and register boots. We pressurize your system, locate every leak with calibrated smoke testing, then seal with mastic or foil-backed butyl tape rated for the temperature swings these attics see. On a 1940s Tudor near Wilson Avenue last month, we dropped leakage from 38% to under 5% — the homeowner’s PG&E bill told the rest of the story.
Flex Duct Repair
Flex duct is the weak link in most retrofitted Old Fig Garden systems. The original 1960s or 70s flex, often attached with degraded duct tape in 140°F attic heat, separates at the collar within a single season. We replace with R-8 insulated flex, secure with mechanical straps and mastic, and support every six feet to prevent sagging that traps debris. This is repair work we do weekly in this neighborhood.
Metal Duct Repair
The original galvanized sheet metal in these estate homes is often sound structurally but riddled with failed seams and corroded spots where condensation has collected for decades. We patch with matching 26-gauge metal, seal with mastic, and insulate where the original installer didn’t. Preserving the metal backbone matters — it’s still the most durable component in a system that may have seen three or four flex retrofits layered on top.
Duct Insulation
Uninsulated or degraded metal duct in Old Fig Garden crawlspaces sweats heavily during Tule fog season, from November through February. That moisture breeds mold, degrades surrounding structure, and gets pulled back into your airflow. We wrap with formaldehyde-free fiberglass or closed-cell foam insulation, sealed at every seam, so your ducts stay dry and your air stays clean.
Mastic Sealant
We use mastic sealant — not duct tape, not caulk — for every permanent seal in Old Fig Garden homes. Mastic remains flexible through decades of thermal cycling, and it’s the only sealant that properly bridges dissimilar materials like original sheet metal to newer flex connections. On retrofitted systems with phased additions, this is often the difference between a repair that lasts five years and one that lasts twenty.
Air Leak Repair
Return air leaks in Old Fig Garden homes are especially problematic given Fresno’s air quality. A return pulling from a vented crawlspace doesn’t just waste energy — it introduces agricultural particulates, wildfire ash, and pollen directly into your living space. We seal returns tight, verify with pressure testing, and document the before-and-after so you know exactly what changed.

Trusted Brands We Service in Old Fig Garden
We stock components from Honeywell, Aprilaire, and Abatement Technologies for Old Fig Garden jobs — brands that hold up to the particulate load and temperature extremes of the San Joaquin Valley. Honeywell media filters and Aprilaire whole-home purifiers integrate cleanly with the mixed-vintage systems common here. We don’t make you wait for parts shipped from Los Angeles. Our van carries the fittings, collars, and sealants that match what your home already has, which means most repairs finish in a single visit.
Common Duct Repair & Sealing Problems We See in Old Fig Garden Homes
- Flex duct attached with degraded tape separates in attic heat. The original installer used cloth-backed duct tape on a 1970s retrofit; by now it’s a dry, crumbly residue. We find the collar hanging open, blowing conditioned air into your insulation. This is nearly universal in pre-1980 retrofits we inspect in Old Fig Garden.
- Uninsulated metal ducts sweat during fog season, growing mold. Tule fog keeps humidity near 100% for days; cold supply lines in vented crawlspaces drip onto subflooring and grow Aspergillus and Cladosporium species. We insulate and seal the vapor barrier.
- Mismatched materials from phased retrofits blow seals at transitions. A 1920s home got sheet metal in the 1950s, flex additions in the 1970s, and a new air handler in the 2000s — each connection point is a pressure imbalance waiting to fail. We engineer smooth transitions with proper dampers.
- Fig tree and oak debris loads overwhelm standard filtration. Old Fig Garden’s dense canopy produces pollen and organic debris that smaller, newer neighborhoods simply don’t generate. Leaky returns pull this material directly into ductwork, where it accumulates in corners and behind dampers.
Pricing for Duct Repair & Sealing in Old Fig Garden, CA
Here’s what duct repair and sealing costs in the Old Fig Garden market, based on the home profiles we service most often:
| Service | Typical Range in Old Fig Garden |
|---|---|
| Duct sealing (whole system, mastic) | $280 – $450 |

Old Fig Garden’s larger homes — many 3,000–5,000 square feet — run toward the higher end of these ranges simply because there’s more ductwork to address. Homes with accessible crawlspaces cost less than those requiring us to work around mature fig tree root systems and hardpan soil beneath pier-and-beam foundations. We quote upfront, before any work begins. Call (855) 643-8783 for an exact estimate — they’re free, and Ryan Bell will walk your system with you.

FAQs — Duct Repair & Sealing in Old Fig Garden
Yes — the particulate load here is among the highest in the United States, and leaky ducts in Old Fig Garden pull that dust directly into your living space. We use mastic sealant rated for agricultural environments and verify with pressure testing that your system runs at negative pressure relative to your crawlspace and attic. Call (855) 643-8783 for a free assessment of your current leakage rate.
It depends on what’s failing. Most Old Fig Garden homes need both: we preserve sound original metal and replace degraded flex that was added in later retrofits. Flex duct repair is faster and less invasive when the metal backbone is intact; metal duct repair is necessary when the original galvanized has corroded through. Ryan Bell evaluates each section individually rather than defaulting to one approach.
Sealing return air leaks is the single most effective step — when your returns pull from sealed ductwork rather than leaky connections in your attic or crawlspace, they draw filtered air through your return grille instead of unfiltered air from around your ducts. We also recommend upgrading to a MERV 11 or higher filter, which we stock from Honeywell and Aprilaire, to capture the heavy organic debris load from Old Fig Garden’s mature canopy.
Tule fog keeps relative humidity above 90% for extended periods, and uninsulated or poorly sealed metal duct in vented crawlspaces sweats continuously. That moisture degrades mastic over time, loosens tape adhesives, and promotes mold growth that re-contaminates your air. We use closed-cell insulation and butyl-backed sealing tapes rated for wet conditions, and we verify no condensation forms after installation.
We preserve visible elements — register grilles, exposed duct chases in basements, original plenum configurations — and we don’t alter architectural features unnecessarily. On the 1930s Spanish Colonial Revival we sealed on W Griffith Way, we routed new flex through existing chases rather than cutting new penetrations, and we matched the original register finishes. Ryan Bell treats your home’s character as a constraint, not an obstacle.
