Richard Anderson has been the lead technician on every job since day one — 14 years focused on one trade, not a generalist operation that added ductwork as a sideline. That matters in a neighborhood where your duct system might run through original lath-and-plaster construction from 1928.
364+ verified customer reviews average 4.9 stars, and we’re proud that many of our Old Fig Garden calls come from referrals within the same block. We know the ZIP 93704 area well — the mature tree canopy that drops debris, the older homes with retrofit HVAC, the specific challenges of working around original architectural details that owners want preserved.

Our Duct Repair & Sealing Services in Old Fig Garden
Duct Sealing
Sealing in Old Fig Garden isn’t a one-product job. We find that homes here often have three or four eras of ductwork layered together — original 1940s sheet metal, a 1970s flex addition, maybe a 1990s retrofit to a converted attic space. Each material needs a different approach. We use mastic sealant on metal joints where thermal expansion has opened gaps, and specialized foil tape rated for high-temperature cycling on flex connections. The valley’s temperature swings — 110°F summers to frosty winter mornings — stress these mixed systems harder than uniform modern construction.
Flex Duct Repair
Flex duct in Old Fig Garden’s older homes is often the weak link. It was run through spaces never designed for ductwork — between plaster and exterior walls, through crawl spaces with 18-inch clearances, around structural elements that create sharp bends. We regularly find flex that has disconnected at collars, been crushed by settled insulation, or torn on old construction debris. Our Nikro negative-air extraction system lets us clean and inspect these runs before repair, so we’re not sealing over a duct that’s packed with decades of agricultural dust and fig-tree pollen.
Metal Duct Repair
The original sheet metal in Old Fig Garden’s pre-1950 homes was built to last — but not necessarily to be airtight by modern standards. Seams were folded, not sealed. Branches were added with rough cuts. We’ve repaired metal duct that has rusted through from decades of condensation, been punctured by later electrical or plumbing work, or simply separated at joints after 80 years of vibration. Where possible, we preserve original runs rather than replacing them, matching gauge and fabrication style to maintain the system’s character.
Duct Insulation
Insulation in Old Fig Garden’s unconditioned spaces is often original or was added haphazardly during a 1980s energy retrofit. We find R-values below current standards, vapor barriers facing the wrong direction, and insulation that has become a filter for valley dust — trapping particulates against the duct surface and accelerating corrosion. We install properly specified insulation with sealed vapor barriers, sized for the San Joaquin Valley’s temperature extremes and particulate load.

Trusted Brands We Service in Old Fig Garden
We carry Honeywell and Aprilaire media filters and filtration components on our trucks — the same brands we install for Old Fig Garden homeowners dealing with heavy valley particulate loads. For sealing materials, we stock professional-grade mastic compounds and reinforced foil tapes rated for the thermal cycling these older systems experience. Our Rotobrush and Nikro equipment is the same rotary brush and negative-air extraction setup used by commercial restoration contractors, not a shop vac with a brush attachment. We don’t have to order parts and come back. Most Old Fig Garden jobs are completed in one visit because Richard Anderson arrives with the right materials for 1920s–1950s duct systems.

Common Duct Repair & Sealing Problems We See in Old Fig Garden Homes
- Disconnected flex ducts behind plaster walls. We were called to a 1930s Spanish-colonial home on Huntington Boulevard in Old Fig Garden where the owner complained of uneven cooling and a persistent musty smell. Our crew found that a flex duct run to the master bedroom had disconnected behind a plaster wall, and the entire system was coated with a thick layer of fine agricultural dust and fig-tree pollen. We reconnected the duct, applied mastic sealant to all joints, and installed a Honeywell media filter to capture the heavy valley particulates — restoring balanced airflow and indoor air quality.
- Mastic sealant failure in mixed-era connections. Old Fig Garden’s duct systems often join 1940s sheet metal to 1970s flex with sealant that has hardened and cracked after decades of seasonal expansion and contraction. These hidden leaks pull attic dust and crawl space moisture into living spaces, and they create pressure imbalances that draw in unfiltered outside air.
- Crushed or kinked retrofit runs. Ductwork added through Old Fig Garden’s tight crawl spaces and finished attics frequently gets compressed by settled insulation, construction debris from later renovations, or simply the shifting of 90-year-old framing. Restricted airflow forces the HVAC system to run longer, pushing more valley particulates through the remaining open paths.
- Return-air pathways choked by organic debris. The neighborhood’s namesake mature fig trees contribute a dense seasonal pollen and organic debris load that coats return-air filters and duct interiors faster than nearly anywhere else in the Fresno metro. We’ve found return plenums in Old Fig Garden packed with material that reduces airflow by 30% or more.

Three factors push Old Fig Garden jobs toward the higher end: plaster-wall access requiring careful cutting and repair, crawl space work in tight clearances, and the extra cleaning time these debris-heavy systems need before sealing. We don’t quote over the phone for concealed repairs — we need to see what’s behind that wall or under that house.

FAQs — Duct Repair & Sealing in Old Fig Garden
Old Fig Garden’s housing stock is 70–100 years old, with ductwork retrofitted through original plaster walls and tight crawl spaces rather than designed into the structure. These retrofit runs have more joints, sharper bends, and mixed-era materials that fail faster than the integrated duct systems in homes built after 1980. The neighborhood’s mature fig trees and San Joaquin Valley particulate loads accelerate wear by coating and clogging these already-stressed systems. Call (833) 958-5022 and Richard Anderson can assess whether your home’s ductwork is due for inspection.
The valley’s bowl topography traps agricultural dust, pesticide drift, wildfire smoke, and vehicle emissions — consistently producing some of the nation’s highest PM2.5 readings. In Old Fig Garden’s older, leakier duct systems, these particulates infiltrate through failed seals and disconnected joints, coating interiors and accelerating material degradation. Proper sealing with mastic rated for thermal cycling is essential to keep this valley air out of your living space. We include particulate-load assessment in every Old Fig Garden estimate — call (833) 958-5022 for a free evaluation.
Yes, in most cases we can access flex duct runs through existing register openings or small, strategically placed openings that we repair and blend. For metal duct behind plaster, we sometimes need to cut access panels, but we work with the wall’s construction — lath-and-plaster requires different technique than drywall — and coordinate finish repair with local trades we trust if needed. Richard Anderson will explain the specific approach for your home before starting. Call (833) 958-5022 to discuss your situation.
We use professional-grade mastic compounds and reinforced foil tapes rated for the extreme thermal cycling that Old Fig Garden’s mixed-era duct systems experience. For filtration upgrades after sealing, we install Honeywell and Aprilaire media filters sized to handle the valley’s heavy particulate load. These aren’t hardware-store products — they’re the same materials we specify for commercial restoration work in agricultural and wildfire-affected buildings. Call (833) 958-5022 and we can detail what’s appropriate for your specific system.
We recommend inspection every 3–5 years for Old Fig Garden homes, with sealing touch-ups as needed based on condition. The combination of mature fig-tree pollen, valley agricultural dust, and thermal stress on retrofit ductwork means seals degrade faster here than in cleaner climates or newer construction. Homes with original 1920s–1950s duct infrastructure may need more frequent attention to joints and flex connections. A free inspection will give you a clear timeline — call (833) 958-5022 to schedule with Richard Anderson.
