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.

AfterFast, Reliable Dryer Vent Cleaning Across Longmont
Dryer vent cleaning in Longmont typically runs $149-$289 for a standard single-family home, and we’re usually scheduling within 3-5 business days during peak season. Our crews work the full Longmont area, from the historic brick homes around Old Town to the ranch neighborhoods east of Main Street and the newer builds near Union Reservoir.
We dispatch from our Denver office, but our techs live and work this corridor daily. They know the difference between a 1920s balloon-frame house on Terry Street and a 1970s split-level off Ken Pratt Boulevard, and they know which one has a 40-foot flexible duct run that’s been sagging in the crawl space since the Ford administration. If your dryer’s taking two cycles to finish a load, or you’re finding lint behind the machine that doesn’t match what the trap caught, the duct’s the problem. Call (970) 598-0453 and we’ll get you a written price before anyone starts.
Why Emberly Chimney Cleaners Boulder Is Longmont’s Preferred Dryer Vent Cleaning Company
We’ve done enough work in Longmont to know the patterns. The Chinook winds that tear through the St. Vrain Canyon gap don’t just rattle windows; they peel exterior vent hoods off east-facing walls and drive rain and snow straight into duct runs that were never designed for that kind of exposure. Our techs check for that. They also know that a home near the 2013 flood corridor along the St. Vrain may have moisture damage at the wall penetration that a standard cleaning company won’t catch.
Our customers in Longmont leave reviews that mention specifics: the photo they got of the packed lint at the second elbow, the written price that matched the final invoice, the text when the tech was ten minutes out. We don’t ask for trust; we document what we found and let you see it.
Response time to Longmont runs 3-5 days for standard bookings, sooner if there’s an active safety concern. We don’t promise same-day because we won’t send someone to your house unprepared. Every truck carries wind-rated termination hardware from Famco and Copperfield, plus the extension rods and cameras to inspect full duct runs, not just the first six feet.
Live phone support runs 24/7. A real person answers, takes your information, and gets you a written estimate with scope and price before we dispatch. That’s Clause 1 of the Haven Standard: “Have it in writing.” No exceptions.
Our Dryer Vent Cleaning Services in Longmont
Complete Dryer Vent Cleaning and Lint Removal
We clean the full duct run from the dryer connection to the exterior termination, using rotary brushes and high-velocity vacuums that pull lint out rather than pushing it deeper. In Longmont’s older homes near Old Town, we regularly find ducts that were retrofitted through balloon-frame walls with multiple unmarked elbows; our camera lets us map the run and make sure we’re not leaving packed lint behind a hidden turn. A typical cleaning runs $149-$219 for a single-story with accessible ductwork.
Dryer Vent Repair and Rerouting
Sagging flexible duct, crushed sections, and improper slopes are common in Longmont’s 1960s-1980s ranch and split-level stock on the east side, where builders often ran 25-foot flexible ducts through crawl spaces with no support. We replace these with rigid metal duct where code allows, supported at proper intervals, and we document the before-and-after with photos. Repair and rerouting work typically falls between $189-$289 depending on access and materials.
Exterior Vent Hood and Termination Replacement
This is the Longmont-specific service we do more of than almost anywhere else in our territory. The Chinook downslope winds funneled through St. Vrain Canyon regularly blow off standard louvered hoods and force moisture past flimsy screens. We install wind-rated hoods with secure four-point attachment and proper backdraft dampers, using hardware rated for the gust loads this corridor sees. Hood replacement with cleaning runs $179-$249.
Camera Inspection and Airflow Verification
Every dryer vent cleaning we perform in Longmont includes a camera scan of the duct interior and a measured airflow reading at the termination. You’ll get photos of what we found, a written summary, and the airflow number in cubic feet per minute. If the duct doesn’t meet manufacturer specs after cleaning, we keep working until it does or we tell you exactly why it can’t. This documentation is standard under Haven Standard Clause 4, not an optional add-on.

BeforeAfterTrusted Brands We Service in Longmont
We stock termination hardware and replacement materials from Famco, Copperfield, and DuraFlex, sourced through Haven’s buying network to keep prices honest. For Longmont customers, that means we’re not ordering a wind-rated hood after we see your house; we’re carrying it on the truck. Same for rigid duct sections, fire-rated wall penetrations, and the specialized collars for older masonry installations. If your vent configuration needs something we don’t stock, we tell you before we book, not when the tech is standing in your laundry room.
Common Dryer Vent Cleaning Problems We See in Longmont Homes
- Exterior hoods blown off by Chinook winds. The downslope winds through St. Vrain Canyon hit east and south-facing walls with sustained force that standard louvered hoods aren’t built for. We find hoods cracked, missing, or hanging by a single screw, with lint packed around the opening and moisture staining the wall board behind.
- Freeze-thaw damage at wall penetrations. At 5,000 feet with aggressive temperature swings, the mortar and sealant around where the duct exits the wall cracks and spalls. Wind-driven rain gets in, freezes, expands, and opens the gap wider. By year three or four, you’ve got a leak path that rots siding and rusts duct collars.
- Long, unsupported flexible duct runs in east-side ranches. The 1960s-1980s tract homes east of Main Street and Ken Pratt Boulevard often have 20-35 foot duct runs through crawl spaces with no support straps. The sag creates low points where lint accumulates in layers; a surface cleaning misses it entirely, and the restricted airflow extends dry times and overheats the machine.
- Lint backup after hood screens clog with debris. Longmont’s cottonwood fluff in spring, combined with the fine limestone dust that blows off the Front Range, packs into vent screens faster than in lower-elevation cities. Homeowners clean the screen and think they’re done; the real blockage is six feet back where the reduced airflow let lint mat against the first elbow.

FAQs - Dryer Vent Cleaning in Longmont
Chinook downslope winds through the St. Vrain Canyon gap hit Longmont’s east-facing walls with sustained force that standard louvered hoods can’t withstand. We replace these with wind-rated terminations using four-point mechanical attachment and heavier-gauge metal. Call (970) 598-0453 and we’ll assess whether your current hood is rated for this exposure.
Yes. At roughly 5,000 feet with aggressive temperature swings, the sealant and mortar around your wall penetration cracks and opens gaps where wind-driven moisture reaches the duct collar and surrounding framing. We inspect this as part of every cleaning and reseal with appropriate materials when needed. If you’re seeing stains on interior walls near the vent location, that’s likely the cause.
Every 12-18 months for typical household use; every 6-12 months if you dry pet bedding, towels daily, or run multiple loads per day. Longmont’s combination of wind-driven debris and freeze-thaw wall damage means the exterior termination needs inspection at least annually even if the duct itself isn’t heavily used. We’ll put you on a reminder schedule if you want.
It can be. The 1960s-1980s ranch and split-level homes east of Old Town often have 25-35 foot flexible duct runs through crawl spaces with no support, creating low points where lint accumulates. A surface cleaning won’t address this. Our camera inspection maps the full run, and we’ll recommend rigid replacement with proper supports if we find sagging or blockage. The written price covers whatever we find.
We’re happy to. Our Dryer Vent Cleaning techs are trained to NFPA 211 Level 2 standards and can perform a full chimney inspection with camera scan while on site. Many Longmont customers book both services together, especially before burning season. We’ll quote the chimney inspection separately in writing; there’s no pressure to combine, but there is a convenience to getting both documented in one visit.
