Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in San Mateo, CA
Air duct cleaning in San Mateo runs $350 – $650 for a typical single-family home, with most jobs scheduled within a week and completed in one day. What drives the real price variation here isn’t the size of the house, it’s the era it was built and what kind of ductwork is hidden behind the walls. San Mateo’s fog-belt climate means year-round moisture issues that inland Peninsula cities don’t face, and the mix of 1920s bungalows west of El Camino with sealed high-rises near Hillsdale creates two completely different job profiles. We dispatch crews from our San Francisco Bay Area office and serve San Mateo locally. Call us at (361) 326-5060 for a free estimate.
Why San Mateo Homes Are Different
San Mateo sits squarely in the marine layer, and that fog belt changes everything about ductwork performance. Windows stay closed most of the year, so whatever is in your ducts circulates continuously. The dampness creates condensation inside metal ducting, which means mold and musty odors show up faster here than in hotter, drier Peninsula cities like Redwood City or San Jose.
The housing stock splits the job types in half. West of El Camino Real, the 1920s – 1950s bungalows often have original 4-inch galvanized ducts buried behind plaster with no attic access. We’ve found transite (asbestos-cement) duct runs from the 1940s – 50s in these neighborhoods, and because San Mateo’s pre-1978 housing stock triggers state lead-safe and asbestos survey rules, any duct disturbance requires proper protocol. The Hillsdale and Parkside tract homes from the 1960s – 70s use larger sheet-metal systems with some flex additions. Then there are the newer townhomes and condos at Bay Meadows and downtown, built tight with shared rooftop RTUs and flex duct in chases barely wide enough for a technician. Each needs different equipment, different access strategy, and different pricing.
Our Main San Mateo Services
San Mateo homeowners call us most often for these three jobs. Each has its own dedicated page with full details on what we find in local homes.
Air Duct Cleaning in San Mateo
We clean duct systems using a Rotobrush rotary brush system for light buildup and a Nikro negative-air machine for heavier debris or post-renovation jobs. In San Mateo’s older west-side bungalows, we often start by determining whether the original galvanized ducts are even accessible without cutting plaster. In newer buildings near Bay Meadows, we coordinate with building management for rooftop unit access and work within HOA scheduling windows. Every job gets a written price before we start.

Dryer Vent Cleaning in San Mateo
Dryer vent cleaning in San Mateo addresses a real fire hazard that builds faster in fog-belt homes because lint absorbs atmospheric moisture and clumps. We run a rotary brush and high-velocity vacuum through the full vent run, including rooftop terminations common in San Mateo condos and multi-story townhomes. If the vent is damaged or improperly routed through a fire-rated wall, we flag it in writing. Dryer Vent Cleaning in San Mateo
Duct Sealing in San Mateo
Duct sealing in San Mateo is often the right fix for older homes where replacement isn’t practical. We apply duct sealing mastic to accessible joints and use aerosolized sealant for buried runs, pressurizing the system to verify results. In pre-war bungalows with no attic access, this can be the only way to stop conditioned air from leaking into wall cavities. We test before and after with a manometer, and we show you the numbers.

FAQs About Air Duct Cleaning Company in San Mateo
Single-family homes don’t need permits for standard cleaning. Condos and townhomes in Bay Meadows, downtown, or any building with shared rooftop RTUs typically require 24 – 48 hour HOA notice, which we help coordinate. If your home was built before 1978 and we encounter disturbed lead paint or transite ducts, California law requires proper containment documentation.
