Why Landmark Air Duct Cleaning Service Washington Is University Place’s Preferred Duct Repair & Sealing Company
We’ve spent 11 years as a dedicated air duct and indoor air quality specialist — not a generalist HVAC company tacking on ductwork as an upsell. That single-trade focus shows in how we approach University Place’s unique housing stock. Owner Richard Anderson serves as Lead Technician on every job, so when you book with us, you’re getting direct owner accountability from crawl space to workshop.
Our 732 verified reviews average 4.9 stars, and University Place customers specifically mention our one-trip resolution on complex properties with detached buildings. We don’t rotate through crews — Richard oversees the work personally, which means the technician who diagnosed your system is the same person who seals it.
Response time to University Place averages same-day or next-morning, because we keep marine-grade materials and heavy-gauge replacement duct in stock rather than ordering after inspection. We know the difference between a standard crawl-space seal and a workshop run exposed to Puget Sound moisture, and we arrive prepared for both.
Our Duct Repair & Sealing Services in University Place
Duct Sealing with Mastic Sealant
University Place’s 1950s–1970s ranch homes were built with sheet-metal trunk lines joined by simple mechanical fasteners — not the sealed systems modern code requires. In the damp 98467 climate, those joints corrode and separate, leaking conditioned air into crawl spaces and drawing musty air back into your supply. We brush-apply mastic sealant to every accessible joint, creating a flexible, permanent bond that outlasts tape and withstands the thermal cycling common in properties with long runs to outbuildings. A typical whole-system mastic seal in University Place runs $320–$480.
Flex Duct Repair
Flex duct in University Place’s older ranches takes a beating. The long runs to detached workshops kink around beams and equipment, and the outer insulation wrap deteriorates faster here than inland because of persistent marine humidity. We replaced a crushed section in a ranch off Sunset Drive West where a 14-foot workshop roll-up door had pinched the original flex duct against a steel beam — torn outer insulation, compromised inner liner, and zero airflow to the outbuilding. Our crew installed heavy-gauge metal duct in the damaged span, sealed all branch joints with mastic, and reinsulated with R-8 wrap rated for marine humidity. One trip. No callbacks. Flex duct repairs in University Place typically run $180–$340 per section.
Metal Duct Repair
The original sheet metal in University Place’s postwar ranches wasn’t galvanized to modern standards. In unconditioned workshops and crawl spaces exposed to Puget Sound air, those trunk lines rust through at joints and low points. We cut out corroded sections, fabricate replacement trunk from 26-gauge galvanized steel, and integrate them with existing runs using sealed transition fittings. Metal duct repair in University Place averages $280–$520 depending on linear feet and access difficulty.
Duct Insulation Replacement
Here’s the University Place problem that generic duct guides miss: the vapor barriers under supply runs in these old ranch crawl spaces are often 50-year-old polyethylene that’s brittle or missing entirely. Ground moisture wicks upward continuously — not just in winter — saturating duct insulation and promoting microbial growth inside the wrap where you can’t see it. We pull deteriorated insulation, treat the duct exterior, and install new R-8 insulation with a proper vapor barrier rated for sustained elevated humidity. Full insulation replacement on a typical University Place ranch runs $450–$680.

Trusted Brands We Service in University Place
We work with air quality systems from Honeywell, Aprilaire, and Abatement Technologies — brands specified by restoration contractors and commercial IAQ specialists, not retail shelf items. For University Place properties with integrated air sanitizing alongside duct repair, we stock Honeywell UV treatment components and Aprilaire media filters locally, so we’re not waiting on shipping when your system needs both sealing and filtration upgrades. Our Rotobrush and Nikro equipment handles the cleaning phase before we seal, and we specify Guardsman antimicrobial treatments where duct interiors show biological growth from chronic moisture exposure.
Common Duct Repair & Sealing Problems We See in University Place Homes
- Crushed flex duct in workshop runs. Long flex duct branches to detached outbuildings get pinched against beams during door movement or equipment storage, tearing the insulation and liner simultaneously. We find this regularly in University Place’s acreage properties where workshops have heavy-duty roll-up doors.
- Rusted sheet metal at unconditioned joints. Original ductwork in uninsulated workshops corrodes from Puget Sound marine air year-round, creating hidden leaks that bleed heating and cooling capacity before air ever reaches the vent. These leaks rarely show obvious symptoms until efficiency drops sharply.
- Saturated insulation from failed vapor barriers. Old polyethylene ground barriers in ranch crawl spaces crack and shift, allowing continuous moisture wicking into duct wrap. The insulation becomes a growth medium rather than a thermal barrier — a failure mode far more common in 98467’s bluff-top humidity than in drier Pierce County cities inland.
- Detached mastic at temperature-cycling joints. Long duct runs to outbuildings experience wider temperature swings than interior branches, causing older sealant to crack and separate. We see this where workshop supply lines branch from main trunks in unconditioned spaces.

FAQs — Duct Repair & Sealing in University Place
Your workshop duct runs through unconditioned space directly exposed to Puget Sound marine air, and the original insulation wrap lacks a vapor barrier rated for sustained humidity. We replace saturated insulation with R-8 wrap and marine-rated vapor barrier, then seal all joints with mastic to prevent moisture infiltration at connection points. Call (877) 335-1974 for an inspection — estimates are free.
Yes — we regularly work in University Place’s 1950s–1970s ranches with 18–24 inch crawl spaces, using compact tools and flexible access equipment designed for tight quarters. Richard Anderson assesses access during the free estimate and plans material cuts and joint configurations before entering, minimizing time in constrained spaces. Most low-clearance repairs in 98467 complete in 3–4 hours.
Proper mastic sealing eliminates the negative pressure that draws crawl space air into your supply, which is the primary source of musty odors in University Place’s older split-levels with vented crawl spaces. If microbial growth has already established inside the duct, we recommend cleaning with Rotobrush treatment before sealing — sealing alone won’t remove existing contamination. Combined cleaning and sealing in split-levels typically runs $580–$840.
We repair and replace the ductwork itself — the crushed, torn, or disconnected runs damaged by door movement or equipment storage — but we don’t service the door openers or mechanical components. If your roll-up door has damaged the duct, we’ll fix the duct and recommend a qualified door technician if the opener needs adjustment to prevent recurrence. Most workshop duct repairs in University Place complete same-day.
Properties with detached workshops add 2–3 hours to a standard residential repair because of longer runs, separate access points, and the need for marine-rated materials. A typical University Place ranch with one outbuilding runs 4–6 hours total. We schedule accordingly and arrive with all materials — no return trips for forgotten R-8 wrap or heavy-gauge replacement sections. Call (877) 335-1974 to book — we’ll confirm timing when you describe your property layout.
