Opening, assessing, and restoring the system that touches every room — for households in San Mateo and across San Mateo County, held to the sensitized-occupant standard and independently verified.
Why this matters in San Mateo
Every market fails in its own way, and San Mateo is no exception. Below: the local failure patterns this service has to account for, and how vetted matching keeps the work honest across San Mateo County.
Mid-Peninsula transition between fog belt and bay flats; wet winters, damp marine mornings. Pre-war stock on raised foundations plus mid-century ranches — winter crawl-space humidity and original galvanized plumbing recur.
Where the work starts in San Mateo
- Vented crawl-space humidity, insulation contact, and subfloor moisture gradients
- Fog-side and north-facing elevations for chronic condensation loading
- Original supply-line runs and angle stops inside wet walls
- Unvented wall cavities and single-pane condensation zones in original assemblies
- Shower and tub assemblies past their service life
What's included
- Opened-equipment inspection: coil compartment, blower assembly, plenum interiors
- Duct material assessment: sheet metal versus porous liner and duct board
- Mechanical cleaning of metal components that can be verified clean
- Replacement of colonized porous components — liner, duct board, affected flex
- Condensate system correction: drainage, pan, float switch
- Filtration upgrade sized to the system's static pressure, sealed against bypass
- Blind duct cleaning with no equipment inspection
- Fogging 'sanitizer' through the ductwork
- UV lights sold as remediation for an already-contaminated system
A mechanical system that passes opened-equipment inspection and supports — rather than sabotages — your whole-house clearance.
