AfterFast, Reliable Dryer Vent Cleaning Across Lafayette
Dryer vent cleaning in Lafayette typically runs $150 – $280 for a standard residential clean, and most jobs take 60 – 90 minutes from arrival to final airflow test. If your dryer is taking two cycles to dry a load, or if you smell burning lint near the laundry area, the vent run is likely restricted and needs immediate attention.
We serve Lafayette from our San Francisco Bay Area dispatch office, with crews routing daily through the 94549 zip code and surrounding Contra Costa Valley neighborhoods. Whether you’re in a 1930s storybook cottage off Moraga Road or a hillside ranch above Happy Valley, we know the vent configurations these older homes hide. Our Dryer Vent Cleaning team carries rotary agitation tools, negative-air extractors, and replacement vent hoods on every truck, so we fix what we find instead of scheduling a return trip.

Why Hollis Air Duct Cleaning Is Lafayette’s Preferred Dryer Vent Cleaning Company
Hollis has been part of the Garrison Partners family since 2004. In Lafayette, that longevity matters because we’ve worked on the same homes multiple times over the years, tracking how original 1940s vent materials degrade and what retrofits previous owners attempted. We know which hillside neighborhoods above Mt. Diablo Boulevard have the longest flex runs, and which pockets near the Lafayette Reservoir see the worst acorn infiltration each October.
Our technicians are background-checked, uniformed, and expected to operate under The Garrison Code: arrive inside the quoted window, price the job in writing before touching anything, complete the work by the book, and leave the site clean. No exceptions. The 365-Day Done Right Promise backs every repair in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit if needed.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday morning to schedule.
Dryer Vent Cleaning Service in Lafayette
Dryer Vent Cleaning Service in Lafayette addresses more than lint buildup in the visible trap. We clean the full run from the dryer’s internal lint pathway through the wall, attic, or crawlspace termination, removing accumulated debris that restricts airflow and creates fire risk. Most Lafayette homes need this service every 12 – 18 months, though hillside properties with heavy oak canopy exposure often require annual attention due to exterior debris infiltration.
A standard clean in Lafayette runs $150 – $220. If we find a sagging flex run, disconnected joint, or damaged termination hood that needs replacement during the cleaning, we’ll show you the issue, quote the repair in writing, and proceed only with your approval. No invoice surprises.
Camera Inspection and Airflow Testing
We run a borescope through the vent run before and after cleaning, so you see the restriction, not just hear about it. Post-clean airflow is measured with a calibrated anemometer. The reading is recorded on your invoice. This matters in Lafayette’s older homes, where hidden junctions in attics or crawlspaces can leak lint into living spaces for years without visible warning.
Negative-Pressure Extraction Method
Our Nikro negative-air machines create suction at the exterior termination while rotary brushes agitate lint and debris inside the run. This dual-action approach pulls dislodged material out of the system rather than pushing it deeper. In Lafayette’s long hillside vent runs, pushing debris backward often creates a new blockage. Extraction is the correct method here.
Dryer Vent Installation in Lafayette
Dryer Vent Installation in Lafayette is often the real solution when cleaning alone won’t fix the problem. Many older homes in the 94549 area have flex runs that sag, kink, or exceed the 25-foot maximum length specified by dryer manufacturers. Others have terminations that exhaust into garages, crawlspaces, or attic spaces, violating current fire safety standards. We replace these configurations with rigid metal ducting, proper slope, and code-compliant exterior terminations.
New vent installation in Lafayette typically costs $280 – $450 for a standard through-wall or through-roof run up to 15 feet. Longer runs, roof terminations, or wall repairs add to the scope. We price every element in writing before work begins.
Rigid Metal Ducting Replacement
We replace sagging flex runs with smooth-wall galvanized or aluminum rigid ducting, secured with metal screws and sealed with high-temperature mastic. Rigid ducting maintains airflow efficiency and won’t trap lint in low spots. In Lafayette’s crawlspace-heavy housing stock, this upgrade often pays for itself in reduced drying time and extended dryer life.
Proper Termination Hoods and Pest Screens
Exterior terminations in Lafayette need hoods that block rain and pests without restricting airflow. We stock Honeywell and Guardsman vent caps with integrated pest screens, properly sized for the duct diameter. The wrong cap, or a screen with too-fine mesh, creates back-pressure that mimics a clogged vent. We match the hardware to your specific run length and dryer CFM rating.
Trusted Brands We Service in Lafayette
We carry replacement parts from Aprilaire, Abatement Technologies, Guardsman, and Rotobrush on our Lafayette-area trucks. This inventory matters because a vent cleaning often reveals a failed backdraft damper, a cracked termination hood, or a missing pest screen that needs immediate replacement. Instead of ordering parts and rescheduling, we install what we stock and complete the job in one visit. Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines for source extraction, the same tools commercial crews use in multi-story buildings. For Lafayette homeowners, that means no gap between diagnosis and repair.
Common Dryer Vent Cleaning Problems We See in Lafayette Homes
- Acorn and leaf debris in exterior terminations. Lafayette’s hillside oak canopy drops material directly onto vent hoods each fall. Our techs routinely clear compacted acorn caps, leaf litter, and rodent nesting material from exterior screens in neighborhoods above Happy Valley and along the Moraga border.
- Sagging flex runs in unconditioned crawlspaces. Many 1940s – 1950s ranch houses in Lafayette have dryer vents routed through crawlspaces that were never designed for ductwork. The flex pipe sags into loops where lint accumulates, and the low spots often trap moisture from ground evaporation, creating packed clogs that resist standard cleaning.
- Disconnected or hidden junctions from DIY retrofits. In Lafayette’s older storybook cottages, previous owners or handymen sometimes added vent extensions in tight attic spaces without proper support or sealing. We find these junctions leaking lint into insulation or living areas during camera inspection. The fix is reconfiguration, not just cleaning.
- Excessive run length exceeding manufacturer specifications. Hillside homes in Lafayette often position laundry rooms far from exterior walls, resulting in vent runs of 35 – 50 feet with multiple elbows. Each 90-degree elbow adds equivalent length to the run. These configurations require booster fans or rerouting to achieve safe, efficient airflow.

FAQs About Dryer Vent Cleaning in Lafayette
Restricted airflow is the cause in nearly every case. In Lafayette specifically, the restriction is often a combination of lint buildup and exterior debris, acorn caps, or rodent nesting material in the termination hood, especially in hillside neighborhoods under oak canopy. Our techs find this exact pattern dozens of times each fall. Call (361) 326-5060 and we’ll run a camera inspection to locate the blockage and quote the fix in writing.
Most Lafayette homes need cleaning every 12 – 18 months. Homes under heavy oak canopy or with long crawlspace vent runs should schedule annually, ideally in late September before the fall debris drop begins. If your dryer is taking longer than 45 minutes for a standard load, you’re already overdue. We can put you on a reminder schedule so you don’t have to track it.
Yes, regularly, especially in hillside homes near the Lafayette Reservoir and along the Moraga border where oak canopy is densest. Rodents use vent hoods with missing or damaged pest screens as entry points, building nests from leaves, insulation, and accumulated lint. Our field vignette: our tech was called to a storybook cottage near the Lafayette Reservoir where the homeowner’s dryer was taking two cycles to dry towels. A camera inspection of the lint pathway showed the flexible run had sagged into a crawlspace loop and was packed with acorn fragments and lint; we cleared it with agitation tools under negative pressure and installed a new Honeywell vent hood with a pest screen. We include pest-screen installation or replacement in our standard termination hardware.
We disconnect the dryer, inspect the full run with a borescope, agitate and extract lint and debris using rotary brushes under negative pressure, test post-clean airflow with a calibrated meter, and reconnect everything. If we find damaged materials, disconnected joints, or code violations, we photograph the issue, quote repair in writing, and proceed only with your approval. You receive before-and-after documentation of your specific system.
Yes. Lint is highly combustible, and restricted airflow causes the dryer to overheat. The U.S. Fire Administration reports approximately 2,900 home dryer fires annually, with failure to clean as the leading cause. In Lafayette’s older homes with long, sagging flex runs, the risk is elevated because lint accumulates in low spots where heat concentrates. Annual inspection and cleaning eliminate this hazard. Call (361) 326-5060 to schedule.
