Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterTrusted Dryer Vent Cleaning for San Mateo Homeowners
Dryer vent cleaning in San Mateo typically costs $149-$289 and takes 45 to 90 minutes, depending on vent length and accessibility. We remove lint buildup from the full duct run, not just the trap behind your dryer, because that’s where the fire risk hides. Call (650) 600-3117 for a written price before any work starts.
We’ve inspected and cleaned more than 38,000 vent and chimney systems since 2009, and we’ve seen what happens when dryer vents get neglected. In the Bay Area’s mild, damp climate, lint compacts and holds moisture, accelerating corrosion in galvanized ducts and creating the exact conditions for overheating. San Mateo homeowners in neighborhoods like Baywood-Aragon, Hillsdale, and Shoreview often have longer vent runs due to interior laundry rooms, which compounds the problem. Our technicians are background-checked, uniformed, and licensed, and we text you when we’re on the way. Every job includes a documented photo record under Haven Standard Clause 4, and every price is written before work begins under Clause 1.
What Our Dryer Vent Cleaning Service Includes
Full Vent Run Cleaning and Debris Removal
We clean the entire dryer vent duct from the back of your appliance to the exterior termination, not just the few feet you can reach yourself. Lint accumulates throughout the run, especially at elbows and where flexible transition hose meets rigid duct, and that buildup restricts airflow until your dryer overheats and your energy bill climbs. In San Mateo, we regularly find compacted lint in 20-foot runs through crawl spaces in older Baywood-Aragon homes, and in newer construction near Bay Meadows where builders used thin, corrugated flex duct that traps debris. We use rotary brushes and high-velocity air tools sized to your duct diameter, and we collect the debris so it doesn’t end up in your laundry room or attic.
Airflow and Back-Pressure Testing
We measure airflow at the exterior vent before and after cleaning, using a digital anemometer to document improvement in cubic feet per minute. A properly functioning dryer vent should move at least 1,500 CFM at the termination; we commonly find readings below 800 CFM in San Mateo homes that haven’t been cleaned in two or more years. High back-pressure strains your dryer’s heating element and blower motor, shortening appliance life and creating the conditions for lint ignition. We record these readings in your job documentation so you have a baseline for future comparison.
Transition Hose Inspection and Replacement
The flexible hose behind your dryer, connecting the appliance to the wall duct, is where we find the most dangerous conditions: crushed hose from pushing the dryer too close to the wall, kinks at sharp angles, and deteriorated foil or plastic hose that no longer meets California building code. We inspect this transition for proper material, typically rigid or semi-rigid aluminum, and replace it when we find substandard installations. In San Mateo, we’ve replaced hundreds of white vinyl transition hoses that were banned years ago but still sit behind dryers in homes purchased between 2015 and 2020. If replacement is needed, we quote it in writing before proceeding.
Exterior Vent Termination Inspection
We inspect the exterior hood for proper operation of the damper, screen condition, and correct clearance from grade and combustibles. Bird screens and flapper dampers stick open or closed in San Mateo’s salt air, particularly in Shoreview and Marina Lagoon homes within a mile of the bay. A stuck-open damper lets in cold air and pests; a stuck-closed damper traps moisture and lint inside the duct. We document the termination condition with photos and note any code deficiencies, such as vents terminating under decks or too close to windows, which we see in hillside homes above El Camino Real.
Interior Dryer Cavity and Blower Housing Cleaning
Lint bypasses the trap and collects inside the dryer cabinet, around the heating element, and in the blower wheel housing. This is the most dangerous location because it’s where ignition temperatures are highest and where a fire can start even when the vent duct itself is clean. We remove accumulated lint from these accessible interior areas, using compressed air and specialized tools that don’t damage sensitive components. We do not disassemble sealed electrical or gas components, but we clean what we can reach and document what we find. If we observe significant internal buildup that requires appliance service, we tell you plainly and can recommend qualified local technicians.
Written Condition Report and Photo Documentation
Every dryer vent cleaning concludes with a written report and time-stamped photos of the vent interior, exterior termination, and any conditions we observed. This documentation is archived under Haven Standard Clause 4, our practice since 2009, and is available to you for insurance or real estate transaction purposes. San Mateo homeowners selling homes in the current market increasingly need this documentation for buyer disclosure packages. We email the report within 24 hours, and we keep the archive indefinitely so you can request copies years later.

Brands We Service for Dryer Vent Cleaning
We clean and service dryer vent systems connected to all major appliance brands, including those vented through Famco and Copperfield termination hardware. Famco’s louvered dryer vent hoods are common in San Mateo homes built between 2010 and 2020, and we’ve serviced hundreds of these units, replacing stuck dampers and corroded screens with identical or upgraded components from our stocked inventory. Copperfield’s heavy-gauge galvanized wall thimbles and firestop assemblies appear frequently in multi-story townhomes near Bay Meadows and in the transit-oriented developments along El Camino Real, where fire-rated penetrations are required by code.
We also work with DuraFlex and HeatShield materials when vent repairs or reroutes are needed, particularly in older San Mateo homes where original ductwork has corroded or where previous remodeling created improper slopes or sagging runs. Whether your dryer is a Bosch, Miele, LG, Samsung, Whirlpool, or any other make, and whether your vent terminates through a Famco hood, a Copperfield assembly, or any other configuration, we can inspect, clean, and document the system to the Haven Standard.
BeforeAfterSigns You Need Dryer Vent Cleaning Right Now
- Clothes take more than one cycle to dry. This is the most common symptom we hear from San Mateo homeowners, and it almost always indicates restricted airflow from lint buildup. Your dryer is working harder, running longer, and building more heat with each extended cycle.
- The dryer exterior or laundry room feels unusually hot. Excess heat means exhaust air isn’t escaping efficiently. In extreme cases, we’ve measured surface temperatures above 140°F on dryer cabinets in homes near Hillsdale where vents hadn’t been cleaned in four years.
- You smell burning or musty odors during dryer operation. Lint is highly combustible, and a burning smell indicates it’s overheating somewhere in the system. Musty odors suggest moisture trapped in compacted lint, which accelerates duct corrosion and mold risk.
- Visible lint accumulates around the exterior vent opening. If lint is escaping the duct at the termination, there’s significantly more trapped inside. We frequently find this in San Mateo homes with bird screens that have never been removed for cleaning.
- It’s been more than 12 months since your last professional cleaning. The National Fire Protection Association recommends annual dryer vent cleaning for single-family homes, and more frequently for households with heavy usage. If you can’t recall the last cleaning, or if you purchased your San Mateo home without documentation of one, you’re overdue.
Our Dryer Vent Cleaning Process - Step by Step
- 1
Arrival and written price confirmation. Your technician arrives in a marked vehicle, uniformed, with license information visible. We confirm the scope and written price before entering your home. No surprises, no upsells after we’re inside. This is Haven Standard Clause 1: have it in writing.
- 2
Pre-cleaning airflow measurement and exterior inspection. We test airflow at the exterior termination with a digital anemometer and photograph the vent hood condition. This establishes baseline performance and identifies any immediate safety concerns, such as a stuck damper or damaged screen.
- 3
Rotary brush cleaning of the full duct run. Using flexible rods and brushes sized to your duct diameter, we agitate and remove lint from the entire vent path. For longer runs in San Mateo hillside homes, we may access the duct from both the interior and exterior to ensure complete cleaning. We collect all debris in a contained vacuum system.
- 4
Transition hose inspection and interior dryer cavity cleaning. We pull the dryer to inspect the transition hose for proper material, support, and condition, replacing it if needed with your written approval. We clean accessible lint from the dryer cabinet and blower housing, then return the appliance to position with proper clearance from the wall.
- 5
Post-cleaning airflow test and documentation. We remeasure airflow to confirm improvement, typically seeing increases of 50% or more. We photograph the cleaned vent interior and exterior termination, then compile your written report with before-and-after readings, photos, and any recommendations. The report is emailed within 24 hours and archived under Haven Standard Clause 4.
How Much Does Dryer Vent Cleaning Cost in San Mateo?
A typical dryer vent cleaning in San Mateo runs $149-$219 for a single-family home with a standard vent run of 15 feet or less, accessible from both interior and exterior. Longer runs, typically 20-35 feet through crawl spaces or attics common in Baywood-Aragon and Aragon homes, range from $189-$289. Transition hose replacement adds $35-$75 depending on length and whether a new wall elbow is needed. Exterior vent hood replacement, when the damper or screen is damaged, runs $65-$125 including parts and labor.
Several factors affect your specific price. Duct length and number of elbows increase cleaning time and tool requirements. Accessibility matters: vents routed through finished basement ceilings or second-story walls take longer to access safely. The condition of existing hardware affects whether replacement is recommended, and we only recommend replacement when we can show you photo evidence of the defect. Multi-unit buildings and commercial dryers require custom quotes based on system configuration.
To avoid overpaying, get any quote in writing with the scope specified, and verify that the price includes the full duct run, not just the transition hose behind the dryer. Some San Mateo-area competitors advertise low base prices that exclude the actual vent cleaning. Our price covers the complete service, and we deliver it in writing before work starts under Haven Standard Clause 1. Estimates are free, and we offer a Free Second Opinion on any competitor’s written estimate.

Frequently Asked Questions - Dryer Vent Cleaning in San Mateo
Dryer vent cleaning is the removal of lint and debris from the exhaust duct that carries hot air from your clothes dryer to the exterior of your home. You need it because lint buildup restricts airflow, forces your dryer to overheat, and creates the leading cause of residential dryer fires. In San Mateo’s climate, moisture-compacted lint also corrodes metal ducts and can support mold growth in wall cavities.
Most residential dryer vent cleanings take 45 to 90 minutes from arrival to completion, depending on duct length, accessibility, and whether we find conditions requiring additional work. A straightforward single-story home in San Mateo’s Hillsdale area with a short, accessible vent typically takes under an hour. Longer runs through crawl spaces or with multiple elbows, common in older Baywood-Aragon homes, extend toward the 90-minute range.
Dryer vent cleaning in San Mateo typically costs $149-$289, with most single-family homes falling in the $149-$219 range for standard vent configurations. Longer ducts, transition hose replacement, or exterior hood replacement increase the total. We deliver a written, itemized price before any work starts, and estimates are free. Call (650) 600-3117 for your specific quote.
We clean the vent system, not the appliance itself, so we service all dryer brands including Bosch, Miele, LG, Samsung, Whirlpool, Maytag, GE, and Speed Queen. We also inspect and replace Famco, Copperfield, and other vent termination hardware. If we find an appliance issue requiring repair, we’ll document it and can recommend qualified local service providers.
We do not advertise same-day dispatch because proper scheduling allows us to assign the right technician and equipment for your specific vent configuration. However, we answer calls live 24 hours a day, 7 days a week, and we prioritize appointments for conditions we assess as elevated fire risk based on your description. Most San Mateo homeowners are scheduled within 3-5 business days.
Every dryer vent cleaning is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. This covers our workmanship and materials for a full year. If airflow readings don’t meet our standards or if lint debris remains in the duct, we return at no charge to correct the deficiency. The promise is stamped on every job under the Haven Standard.
Clear a path to your dryer and remove items stored on or immediately around it so our technician can safely pull the appliance for transition hose inspection. If your dryer is in a garage or exterior closet, ensure we have workspace access. You don’t need to clean the lint trap beforehand, but do let us know if you’ve noticed any symptoms like extended dry times or unusual odors. Call (650) 600-3117 to schedule, and we’ll confirm any location-specific preparation when we book your appointment.
