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.

Why Emberly Chimney Cleaners San Jose Is Sunnyvale’s Preferred Dryer Vent Cleaning Company
We’ve completed more than 38,000 chimney and vent inspections since 2009, and a significant share of those have been right here in Sunnyvale’s post-war ranch tracts. The reviews we get from Sunnyvale homeowners tend to mention the same thing: the technician showed the photo evidence before quoting a price, and the written scope matched the final bill exactly. That consistency is Haven Standard Clause 1 - written price, written scope, written warranty before any work starts.
Our response time to Sunnyvale neighborhoods runs same-week for standard bookings, with live phone support available 24/7 to coordinate around your schedule. We know the local housing stock cold: the original rigid metal ducts running 20 to 30 feet through uninsulated attics, the crushed flex transitions behind dryers installed by previous owners, and the missing termination caps that let starlings colonize roof vents during Sunnyvale’s six-month dry season.
Every technician we send to Sunnyvale is background-checked, uniformed, and carries a license number you can verify. You’ll get a text when they’re en route, a named tech assigned to your job, and a documented photo record uploaded to your file under Haven Standard Clause 4 - the same archive practice we’ve run continuously since 2009.
Our Dryer Vent Cleaning Services in Sunnyvale

Dryer Vent Cleaning
Our core Dryer Vent Cleaning service addresses the full lint load from the dryer transition through the termination cap. In Sunnyvale’s 1950s-1970s ranch homes, this means handling runs that were designed for shorter ductwork but now stretch through unconditioned attic space where lint cakes against cold metal walls. We use rotary brushes and high-velocity air tools sized to your duct diameter, with a camera verification at the end showing you the clear passage. A typical Sunnyvale ranch-home cleaning runs $149-$219, quoted in writing before we start.

Dryer Vent Termination Cap Inspection and Replacement
Missing or broken caps are epidemic in Sunnyvale after decades of sun exposure on composite or galvanized terminations. During our May-through-October dry season, an open vent is an invitation to starlings, house sparrows, and roof rats. We stock caps from Famco and Copperfield through our Haven buying network, and we carry the common 4-inch louvered and bird-proof styles on every truck. Replacement with proper sealant and screening runs $89-$149 installed, and we’ll show you the old cap and the new fit on camera before we close the ticket.

Full-Duct Lint and Nesting-Debris Removal
When a vent has been compromised by wildlife or long neglect, the standard cleaning isn’t enough. We’ve pulled two-story vertical runs in Sunnyvale homes that were packed solid with compacted lint and nesting material - the homeowner’s dryer had been taking two cycles per load for months. Full-duct restoration includes sectional camera inspection, mechanical removal of blockages, joint inspection for corrosion or separation, and reassembly with proper supports. These jobs run $219-$289 depending on duct length and accessibility, and we document every foot on video.

Transition and Joint Repair
The flex transition behind your dryer is the most abused piece of the system. In Sunnyvale tract homes, we regularly find original 4-inch flex crushed by the dryer being pushed back against the wall, or sagging rigid pipe pulling apart at taped joints. We replace crushed transitions with smooth rigid elbows where code allows, seal joints with proper foil tape (never screws that catch lint), and verify airflow with a manometer reading you’ll see on the report. Small repairs like this are often included in the base cleaning price; larger reconfigurations run $129-$189 if the duct routing needs correction.

Common Dryer Vent Cleaning Problems We See in Sunnyvale Homes

- Crushed flex transitions behind the dryer. A common shortcut in 1950s-1970s tract homes, the original 4-inch flex gets kinked when the dryer is pushed back against the wall. Airflow drops before the main run ever becomes a problem, and the homeowner blames the appliance.
- Missing or broken termination caps. Sunnyvale’s bone-dry May-through-October season is prime nesting time for starlings, house sparrows, and roof rats. An open roof vent becomes a condo, and by November the duct is packed with debris that the first rainy-season laundry load turns into a clogged mess.
- Condensation-wetted lint in uninsulated attic runs. Because the duct usually runs through unconditioned space, temperature swings cause moisture to condense on lint buildup. In homes where the fireplace sees only sporadic use under Spare the Air restrictions, that damp vent quietly corrodes, crushes, or detaches at joints - often unnoticed until the dryer fails or the joint leaks moist air into the attic.
- Two-story vertical runs packed from neglect. The original rigid metal duct in these older ranches often runs 20 to 30 feet. Lint that would stay loose in a short straight run instead clings and cakes along the full length, especially where the duct wall is cold. Annual cleaning prevents the gradual choke that eventually demands full-duct restoration.

FAQs - Dryer Vent Cleaning in Sunnyvale

No. Fireplace use frequency has nothing to do with dryer vent condition. Your dryer runs year-round, and Sunnyvale’s long dry season means lint accumulates continuously while wildlife actively nests in open vents. The fact that your chimney sees little use is actually a local hazard pattern we watch for: homeowners who neglect annual vent service because they assume “barely used” means “automatically clean.” Call (669) 291-2770 for a free camera inspection and written quote.
Extended dry times are the first reliable symptom of a blocked vent, not a failing dryer. In Sunnyvale’s 1950s-1970s ranch homes, the cause is usually a crushed transition behind the unit, a long attic run packed with lint, or a missing termination cap that let birds or rats fill the duct with nesting debris. We recently serviced a 1968 ranch home in the Lakewood tract of Sunnyvale where the homeowner’s dryer had started taking two full cycles to dry a load of towels. Pulling the dryer out, we found the original 4-inch flex transition crushed behind the unit and a two-story vertical run packed with lint and starling nesting debris that had entered through a missing termination cap on the roof. After reconnecting with a smooth rigid transition, clearing the full run, and fitting a proper cap, the homeowner’s dry times dropped back to a single cycle. If your towels need two cycles, your vent needs inspection. Call (669) 291-2770.
Annually, minimum. The National Fire Protection Association recommends annual inspection and cleaning of dryer vents, and Sunnyvale’s specific conditions make that interval prudent rather than conservative. The combination of long rigid duct runs through cold attics, active wildlife pressure during our six-month dry season, and the crushed-transition problem common in these older tracts means lint accumulates faster than in newer construction with shorter, straighter vent paths. Schedule yours at (669) 291-2770.
Yes, routinely. Starlings, house sparrows, and roof rats exploit missing or broken termination caps during Sunnyvale’s bone-dry May-through-October nesting season. A 4-inch vent opening is ideal entry size. We’ve pulled ducts packed solid with twigs, grass, and nesting material that the homeowner never suspected because the dryer still worked - just poorly. A proper bird-proof cap with screening prevents this entirely, and we carry them on every truck. Call (669) 291-2770 to check your cap condition.
Ask for four things: a camera inspection of the full duct run, not just the transition behind the dryer; a manometer airflow reading before and after cleaning; a photo or video record of the duct condition and any repairs; and a written price, scope, and warranty before anyone starts work. These are the core of Haven Standard Clauses 1 and 4, and they’re what separate a documented service from a quick lint-tray swipe. Any technician who won’t provide them is selling you a guess. We provide all four on every Sunnyvale visit. Call (669) 291-2770 to book.
