Using professional-grade Nikro and Rotobrush equipment alongside pressure testing protocols, we locate every breach before we seal a single inch of ductwork.
Our base in Woodland Hills puts us minutes from the Ronald Reagan Freeway and the Burbank Boulevard corridor, which means West Hills jobs rarely carry the extended travel delays that plague contractors coming from further out. When a homeowner near Lakeside Park calls us at 8 a.m., we’re typically able to schedule same-week service — often sooner.
Our Duct Repair & Sealing Services in West Hills
Duct Sealing with Mastic Sealant
Mastic sealant remains the industry standard for sealing duct joints and connections, and it’s what we use on virtually every West Hills job where leakage is present at seams or collars. Unlike tape-based solutions that dry out and peel within a few years — a failure mode we see constantly in the tract homes along Nordhoff Street and the streets feeding off Santa Susana Pass Road — mastic creates a permanent, flexible bond that holds through temperature cycling. A full mastic sealing service for a typical West Hills single-family home runs $350–$650 depending on duct access and the number of connection points requiring treatment.
Flex Duct Repair
The majority of West Hills homes built between the 1960s and 1980s were fitted with fiberglass duct board or flexible duct systems, and a significant portion of those original or once-replaced flex runs are now showing inner liner tears, disconnected joints, and collapsed sections that choke airflow to individual rooms. Scott Hill’s team repairs or replaces damaged flex duct sections using commercial-grade materials rated for the sustained high-heat cycling that Valley summers demand — systems in West Hills regularly push through 105°F+ exterior temperatures, running long daily cycles that accelerate flex duct degradation. Flex duct repair in West Hills typically runs $180–$420 per section, depending on diameter, length, and accessibility.
Metal Duct Repair
Older metal duct systems in West Hills homes — particularly in the larger ranch-style properties near Devonshire Highlands — develop rust at seams, physically separated joints, and holes from pest intrusion or improper previous repairs. We use sheet metal patches, foil-backed reinforcement, and mastic to restore structural integrity to damaged metal runs, tested post-repair with static pressure measurement to confirm the fix held. Metal duct repair in West Hills averages $250–$550 per repair zone, with more extensive sectional replacement running $600–$950 depending on duct diameter and attic or crawlspace configuration.
Duct Insulation
Uninsulated or under-insulated ductwork in a West Hills attic is effectively an expensive mistake — attic temperatures here can exceed 150°F in July and August, meaning conditioned air traveling through bare or degraded duct insulation arrives at the register warmer than it left the air handler. We wrap or replace duct insulation using R-6 and R-8 rated materials appropriate for the Valley climate, a service that frequently reduces cooling costs noticeably in homes that haven’t had insulation addressed since the original construction. Duct insulation work in West Hills runs $400–$900 for a typical single-story ranch-style home, with two-story homes or homes with complex attic geometries running higher.
Trusted Brands We Service in West Hills
Premier Air Duct Solutions works with and around the HVAC systems and components most commonly found in West Hills homes, including Honeywell and Aprilaire air quality and filtration products that pair directly with sealed duct systems for maximum efficiency gains. Our diagnostic and cleaning equipment — Rotobrush, Nikro, and Abatement Technologies units — are the same tools specified for professional remediation work, not consumer-grade vacuums. We also work with Guardsman-rated sealing and protection products where applicable. Stocking components and materials commonly needed for West Hills jobs means we’re rarely making a second trip, and your project gets completed in a single visit whenever possible.
Common Duct Repair & Sealing Problems We See in West Hills Homes
- Woolsey Fire ash residue embedded in duct systems: Technicians working the hillside streets near Red Barn Hill and the Bell Canyon edge consistently find ducts in homes that survived the November 2018 Woolsey Fire coated with a fine, gritty gray-brown residue from burned chaparral and structure material — a contamination that standard filter changes never reached and that continues to recirculate years later. Sealing a duct system without addressing this residue first simply locks the problem in, which is why we assess contamination levels before any sealing work begins.
- Santa Ana wind–driven particulate infiltration at duct joints: West Hills sits at the western mouth of the San Fernando Valley directly against the Santa Susana Pass — one of the Valley’s most active Santa Ana wind channels — and loose duct joints act as entry points for the heavy chaparral dust and fine debris these high-velocity, low-humidity events push through HVAC intakes at rates more severe than interior Valley communities see. We regularly find joints that were previously sealed with duct tape that dried and separated, leaving gaps that have been drawing unfiltered outdoor air for years.
- Collapsed and kinked flex duct in 1970s–1980s tract homes: The aging flex duct systems in West Hills’s original ranch-style housing stock — particularly in homes along the streets feeding off Kuehner Drive and around Lakeside Park — degrade from the inside out, with inner liners cracking and collapsing under decades of heat cycling. A kinked or partially collapsed flex run can restrict airflow to a single room by 40–60%, making that room feel impossible to cool or heat regardless of how the rest of the system performs.
- Under-insulated attic duct runs losing efficiency in summer heat: Many West Hills homes have had duct sections replaced over the years but received insulation that was undersized for the Valley’s extreme summer attic temperatures, or insulation that has since compressed and lost its rated R-value. When we measure supply air temperature at the register versus what’s leaving the air handler, we frequently find 8–15°F losses in homes with degraded attic duct insulation — a gap that translates directly into higher utility bills and longer compressor run times.
The West Hills Duct Problem That Doesn’t Show Up Anywhere Else
West Hills carries a contamination profile that no neighboring community shares at the same intensity. The Santa Susana Pass Road corridor channels Santa Ana wind events directly into the neighborhood’s HVAC intakes, depositing fine chaparral debris and road particulates at rates that dwarf what a community like Van Nuys or Reseda sees during the same wind event. Layer on top of that the Woolsey Fire’s November 2018 burn footprint, which covered significant portions of West Hills, and you have homes where duct systems absorbed both acute fire-event contamination and six-plus years of subsequent wind-driven particulate loading — all without professional remediation in many cases. Sealing those duct systems without first characterizing and addressing what’s inside them doesn’t solve the problem; it seals it in. That’s the dual-contamination reality Scott Hill’s team accounts for on every West Hills job that involves a home built before 2019.
