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.
Fast, Reliable Dryer Vent Cleaning Across San Mateo
Dryer vent cleaning in San Mateo typically runs $180-$340 for a standard single-family home, and most jobs are completed in under two hours with one crew. Morton’s Air Duct Cleaning has served San Mateo since 2005, and our crews know the Peninsula’s bay-side neighborhoods well, from the ranch homes of Baywood to the hillside streets above El Camino Real. Call (323) 918-4345 for a free estimate, or read on to understand why San Mateo’s coastal climate creates dryer vent problems that inland crews often miss.
We’re not strangers passing through. Our scheduling is coordinated from our San Francisco Bay Area office, but the technicians who arrive at your San Mateo door live and work locally. They know the difference between a home built in 1958 with original vent routing and one retrofitted in the 1980s when central HVAC went in. That local knowledge matters when your dryer vent run disappears into a crawl space that hasn’t been opened in twenty years.
Why Morton’s Air Duct Cleaning Is San Mateo’s Preferred Dryer Vent Cleaning Company
San Mateo families call us back because we treat the house like it’s our own. Shoe covers and drop cloths are standard on every visit, not optional. We work around nap schedules when we can, and we choose pet-safe products where they’re available. Every job starts with a written price agreed before any tool comes out of the van, and ends with a photo of the clean-up sent to you before the crew leaves.
Our Dryer Vent Cleaning team arrives in uniform, background-checked, and trained to the Cedarwell C.A.R.E. values. The 365-Day Done Right Promise backs every visit: if something isn’t right, we make it right. No paperwork to hunt down, no manager to escalate through. Paul Adeyemi built Morton’s on that principle when he founded the company in 2005, and it’s still how we operate today.
A live person answers our phone 24/7. Not a chatbot, not a callback queue. When you’re staring at a dryer that won’t finish a cycle and wondering if it’s safe to run another load, that matters.
Dryer Vent Cleaning Company in San Mateo
Dryer Vent Cleaning Company services in San Mateo address a specific coastal problem: lint that stays wet. In most of the country, dryer lint is dry, flaky, and easy to blow out. In San Mateo’s persistent marine-layer humidity, especially in bay-front neighborhoods like Shoreview and North Shoreview, lint absorbs moisture from damp crawl spaces and compacts into dense, heavy mats that cling to duct walls. A standard cleaning that works in Phoenix or even Sacramento often fails here because it doesn’t account for that wet-cling dynamic.
Our process starts with a visual inspection of the full run, from the transition duct behind your dryer to the exterior hood. We use Rotobrush and Nikro equipment to mechanically remove lint buildup, not compressed air that can pack wet lint tighter. For homes with crawl-space runs, we inspect the boot connection at the dryer cabinet and the exterior hood for proper seal and termination. Re-sealing matters here. A loose boot in a damp crawl space pulls humid under-floor air into the lint pathway, accelerating the next buildup cycle.
What the Job Includes
We clean the transition duct, the full vent run, and the exterior hood. We test airflow before and after with a manometer, and we verify the dryer’s amp draw to confirm the motor isn’t fighting restriction. If your vent terminates in the crawl space instead of through the wall, we’ll flag it and explain your rerouting options.
When to Schedule
Two cycles to dry a load that used to take one. A dryer that runs hot to the touch. A musty smell in the laundry room. These are San Mateo’s warning signs, and they appear sooner here than inland because of the humidity factor. Annual inspection is sensible for most homes; every six months if you have a long run, a large household, or pets that shed heavily.
Dryer Vent Inspection in San Mateo
Dryer Vent Inspection in San Mateo is where we find the problems that cause fires and wasted energy before they become urgent. Our inspection covers the full run with a camera where accessible, checks the boot seal and exterior hood condition, and measures airflow and back pressure. In San Mateo’s mid-century housing stock, we frequently find vents that were never properly routed to the exterior when HVAC was retrofitted, or 1970s flex duct that has sagged and partially disconnected at the elbow.
A typical inspection in San Mateo runs $120-$180. If you proceed with cleaning the same day, we apply the inspection fee toward the cleaning cost. The inspection itself takes 30-45 minutes, and you’ll receive a written report with photos of any problem areas.
Camera Inspection of the Full Run
We run a borescope from the transition duct to the hood, looking for sagging flex, disconnected joints, and lint accumulation patterns. In Shoreview, we regularly find the wet-lint slug described above, compacted at the first elbow where the vent dips before rising to the hood. Seeing it on camera removes all guesswork about whether cleaning is needed or whether rerouting makes more sense.
Airflow and Safety Testing
We measure static pressure and temperature at the hood during a dryer cycle. Excessive back pressure indicates restriction. Temperature spikes indicate poor airflow that risks overheating. Both readings go in your report, with recommendations prioritized by safety impact.
Trusted Brands We Service in San Mateo
Morton’s technicians carry parts and tools from Rotobrush, Nikro, and Guardsman on every San Mateo visit. We don’t rent equipment by the day; we own it, maintain it, and know its limits. That means when we find a damaged vent hood in a Baywood home or a disconnected boot in a North Shoreview crawl space, we can often replace or reseal same-day without a return trip. For specialized components, our Bay Area warehouse stocks common sizes of rigid duct, transition hose, and bird guard assemblies. Faster turnaround, fewer appointments, less disruption to your household routine.
Common Dryer Vent Cleaning Problems We See in San Mateo Homes
- Wet lint compaction in bay-front crawl spaces. In Shoreview and lower-elevation North Shoreview, exterior hoods sit under the fog dripline where marine-layer moisture keeps lint damp. The lint clumps into dense mats that restrict airflow far sooner than dry lint would. Mechanical removal with proper rodding tools is the only effective fix; compressed air alone won’t break it loose.
- Vents terminating inside the crawl space instead of through the wall. Common in 1950s-1970s ranch homes where the dryer was originally vented through a foundation vent or into an open crawl space, and never rerouted when HVAC ductwork went in. The vent dumps hot, moist air under the floor, promoting mold and wood decay while recirculating lint into the home’s air.
- Sagging flex duct at the boot pulling humid under-floor air. The 4-inch flex runs installed in San Mateo’s retrofit era have lost tension over decades. A sagging low point becomes a lint trap and a moisture intake point simultaneously. Cleaning without addressing the sag leaves the root cause intact.
- Technicians who clean the trap and call it done. The lint trap catches perhaps 25% of lint generated. The rest travels into the vent run, where San Mateo’s humidity turns it into the wet-slug problem described above. A proper cleaning addresses the full run, not just the accessible parts.
Pricing for Dryer Vent Cleaning in San Mateo, CA
Most San Mateo homeowners pay between $180 and $340 for a complete dryer vent cleaning, depending on run length, accessibility, and whether rerouting or component replacement is needed. Here’s how that breaks down:
| Service | Typical Range in San Mateo |
|---|---|
| Dryer vent inspection | $120-$180 |
| Standard vent cleaning (single-story, wall termination) | $180-$260 |
| Crawl-space or roof-termination cleaning | $240-$340 |
| Vent rerouting or hood replacement | $150-$400 additional |
| Bird guard installation | $80-$150 |
What moves you toward the higher end: a long flex run through a damp crawl space, a roof termination requiring ladder access, or a vent that needs complete rerouting from an interior termination to the exterior wall. What doesn’t affect price: number of laundry loads you run, brand of dryer, or square footage of your home. We quote one flat price per system, agreed in writing before work starts. No per-foot add-ons, no “discovered problems” mid-job. Call (323) 918-4345 for your exact quote; estimates are free.

FAQs About Dryer Vent Cleaning in San Mateo
San Mateo’s coastal humidity causes lint to absorb moisture and compact into dense, airflow-blocking mats, especially in crawl-space vent runs. San Jose’s drier inland climate lets lint stay fluffy and pass through more easily; the same vent configuration performs worse here simply because of ambient moisture. A mechanical cleaning that removes the wet-compacted lint typically restores single-cycle drying. Call (323) 918-4345 to schedule an inspection.
Yes. The lint trap catches roughly a quarter of lint generated per load; the rest enters the vent run. In San Mateo’s humidity, that escaped lint accumulates faster and compacts harder than in drier climates. Cleaning only the trap leaves the restriction in place and the fire risk unaddressed. Our full-run cleaning includes the trap, the transition duct, and the complete vent path to the exterior hood.
Mechanical cleaning physically removes lint and debris from the vent run, restoring airflow. Fogging sprays a chemical mist into the duct without removing the restriction. In San Mateo’s chronic marine-layer humidity, adding moisture to an already damp crawl-space vent does nothing to restore dryer performance and may promote mold growth on the wet lint left behind. We don’t offer fogging as a substitute for source removal; we clean the vent mechanically, verify airflow improvement, and reseal connections to prevent moisture re-entry.
It can be. Eave-mounted hoods in Shoreview sit in the fog-dripline where marine moisture keeps lint wet and heavy. The lint compacts into hard slugs at elbows and low points, restricting airflow far sooner than a wall-mounted hood in a wind-exposed location. We inspect these runs with a camera to assess compaction severity, clean mechanically with rodding tools, and evaluate whether relocating the hood to a more exposed wall location would improve long-term performance. Call (323) 918-4345 for a specific assessment of your configuration.
Annually for most households, every six months if you dry multiple loads daily, have pets that shed heavily, or have experienced wet-lint compaction before. San Mateo’s humidity accelerates buildup compared to inland climates, so the standard “every two years” advice doesn’t apply here. An annual inspection catches sagging flex, disconnected boots, and early compaction before they force your dryer into inefficient double cycles or create safety risks.
