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 Belmont
Dryer vent cleaning in Belmont typically runs $180 – $340 for a standard single-family home, and most jobs are completed in under two hours with the dryer back in service the same day. If your dryer is taking two cycles to finish a load or you’re noticing a musty smell after winter fog rolls through, the problem is usually lint packed into a sagging flex run somewhere in your crawlspace or wall cavity.
We’ve been working in Belmont long enough to know the pattern. The 1940s through 1970s ranchers and two-story traditional homes that make up most of this city’s housing stock were built with tight perimeter foundations and long flex-duct runs through damp crawlspaces. That marine-layer moisture doesn’t just make basements musty; it condenses inside dryer vents and turns loose lint into a soggy, compressed mat that chokes airflow and creates a real fire risk. Our crews serve Belmont from our Boston office, and we carry the rotary brush systems, negative-air machines, and camera inspection gear needed for these older hillside homes. Call (361) 326-5060 for a free estimate and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Belmont’s Preferred Dryer Vent Cleaning Company
Belmont homeowners aren’t looking for the cheapest coupon in the mail. They’re looking for a crew that shows up on time, prices the job in writing, and doesn’t invent problems once the van is in the driveway. That’s exactly how we operate. Every Hollis technician is background-checked and uniformed, and every job is backed by our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit.
We know Belmont’s microclimates cold. The homes off Concord Avenue and the hillside streets near the Santa Cruz Mountains deal with different moisture loads than the flatter neighborhoods closer to the bay. We’ve pulled lint mats out of sagging flex runs in crawlspaces from the 1960s ranchers near Belmont Heights to the two-story homes off Alameda de las Pulgas. Our pricing is flat per system, agreed in writing before we touch anything. No per-foot add-ons, no surprise charges at the door. And when you call (361) 326-5060, a live person answers, 24 hours a day, 7 days a week. No voicemail loops, no callback queues.
Dryer Vent Cleaning Service in Belmont
Dryer Vent Cleaning Service in Belmont means more than vacuuming the lint trap and the first foot of flexible duct behind your dryer. We clean the entire run from the appliance connection to the exterior hood, using camera inspection to locate sags, crushed sections, and lint accumulation that Belmont’s damp crawlspace air has turned into compacted fuel. A typical cleaning for a single-family home in Belmont runs $180 – $240; homes with longer runs, multiple bends, or significant blockage requiring agitation tools and negative-air HEPA extraction run $260 – $340.
Belmont’s specific conditions make thorough cleaning essential here. The marine layer that rolls in from the bay keeps crawlspace humidity high through fall and winter. Lint is hygroscopic, meaning it absorbs that moisture and cakes against duct walls instead of staying loose and blowing through. In the dry summer months, that same packed lint becomes tinder. We’ve found complete blockages in 15-year-old flex runs that homeowners didn’t know existed because the dryer “still worked, just slowly.”
Camera Inspection and Source Removal
We run a borescope camera through the full length of your vent before and after cleaning. You see what we see: the sag where lint pooled, the crushed section from a 1980s remodel, the moisture staining at the low point. Then we remove the source with rotary brush agitation under continuous negative pressure and HEPA filtration. This is genuine source removal, not a surface wipe or a deodorizing spray.
Airflow Verification and Written Documentation
After cleaning, we measure airflow at the exterior hood and provide written documentation of the before-and-after condition. If we find damage that requires repair or re-installation, we explain it with the camera footage and give you a separate written price for that work. Nothing happens without your approval in writing.
Dryer Vent Installation in Belmont
Dryer Vent Installation in Belmont addresses the root problem when cleaning isn’t enough: crushed flex duct, improper pitch that creates new sags, or galvanized runs from the 1960s that have corroded through. A full re-installation in Belmont typically runs $450 – $750 for a standard through-wall or through-roof run with rigid metal duct, proper supports, and a new exterior hood with backdraft damper and bird guard.
Belmont’s mid-century housing stock creates specific installation challenges. Many original runs were flex duct slung through crawlspaces with inadequate slope, no supports, and sharp bends around joists. The hillside lots off Concord Avenue and similar streets often mean 25-foot or longer runs with multiple direction changes, which requires careful calculation of equivalent duct length to ensure your dryer’s blower can handle the static pressure. We use rigid aluminum or galvanized steel, properly pitched back toward the dryer for any condensate drainage, with support straps every 4 feet as code requires.
Rigid Metal Replacement for Long Runs
For Belmont homes with runs exceeding 25 equivalent feet, we spec rigid metal duct with smooth interior walls that won’t trap lint in corrugations. We calculate the actual equivalent length including elbows and transitions, and if your dryer’s blower capacity is marginal, we’ll tell you upfront rather than install something that won’t perform.
Bird Guard and Exterior Hood Upgrades
Belmont’s mature trees and hillside terrain attract birds and rodents to warm vent hoods. We install vent caps with integrated bird guards and backdraft dampers that seal when the dryer isn’t running, keeping pests out and conditioned air in.
Trusted Brands We Service in Belmont
We stock parts and maintain equipment from Rotobrush, Abatement Technologies, and Guardsman so Belmont customers aren’t waiting on special orders for standard repairs. Our rotary brush systems from Rotobrush handle the agitation work in older flex runs without damaging fragile duct, while our negative-air HEPA machines from Abatement Technologies capture the fine particles that Belmont’s wildfire seasons deposit throughout duct systems. Guardsman filtration products supplement our cleanup process when smoke residue is present. For installations, we source rigid metal duct, fire-rated collars, and exterior hoods locally to keep turnaround fast. If your dryer is a Whirlpool, LG, Samsung, Maytag, or another major brand, we work with the vent specifications the manufacturer requires, not a one-size-fits-all approach.
Common Dryer Vent Cleaning Problems We See in Belmont Homes
- Lint caked into soggy mats in crawlspace flex runs. Belmont’s marine-layer dampness condenses inside unconditioned crawlspaces, and lint absorbs that moisture like a sponge. Homeowners who only clean the lint trap and the first foot of duct miss the real blockage 8 feet away where the flex sags against a joist.
- Crushed or kinked sections from decades-old remodels. The mid-century ranchers and two-story homes built from the 1940s through 1970s have seen multiple kitchen and laundry updates. We’ve found flex duct flattened by a cabinet installation from the 1990s, or pinched where a contractor ran electrical through the same chase.
- Smoke residue coating duct interiors after wildfire season. Fine ash particles from Santa Cruz Mountain wildfires penetrate exterior hoods and coat the inside of flexible ducts. Changing your HVAC filter helps your furnace, but it does nothing for the dryer vent that’s been drawing outdoor air all summer.
- Improperly pitched runs that pool condensate. Long hillside runs in Belmont homes often lack the 1/4-inch-per-foot slope back toward the dryer. Water collects at low points, accelerates corrosion in metal ducts, and turns lint into cement-like deposits that standard vacuuming won’t touch.

FAQs About Dryer Vent Cleaning in Belmont
Every 12 to 18 months for Belmont homes with crawlspace-based dryers, and annually if you’re on a hillside lot where marine-layer moisture is heaviest. The damp condenses inside flex runs and accelerates lint compaction, so the standard “every 2-3 years” advice doesn’t apply here. Call (361) 326-5060 and we’ll assess your specific run length and crawlspace conditions.
The smell is mildew growing on lint that has absorbed crawlspace moisture. Fog rolls in, humidity spikes, and lint mats in sagging duct sections stay wet for days. A surface spray or deodorizer masks the odor temporarily; only removing the wet lint source and fixing the sag eliminates it. We see this constantly in the ranchers off Alameda de las Pulgas and the hillside streets near Belmont Heights.
You can rod out a straight run without a camera, but Belmont’s mid-century homes rarely have straight runs. The camera finds the crushed section from a 1990s remodel, the improper pitch creating a water trap, or the corrosion hole you can’t feel from either end. We include camera inspection in our standard cleaning because guessing wastes your time and our reputation. The footage also proves the work was done right.
No. Fogging masks odor for a few weeks but does not remove smoke residue or lint from your dryer vent. The fine ash particles from wildfire smoke coat duct interiors; a chemical sponge treatment under negative pressure with HEPA filtration removes them. Fogging is an upsell that leaves the real problem in place. We don’t offer it because it doesn’t work.
Corroded galvanized steel, multiple crushed sections, or a run that exceeds 35 equivalent feet with inadequate blower capacity usually means re-installation. We show you the camera footage and explain the static pressure calculation. If cleaning will leave you with a marginal system, we’ll tell you upfront and give you a written price for both options. Call (361) 326-5060 for an honest assessment.
