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.
Trusted Dryer Vent Cleaning for Littleton Homeowners
Dryer vent cleaning in Littleton typically costs $150-$350 for a standard single-family home and takes 60-90 minutes from arrival to photo documentation. CleanRun Air Duct Cleaning Littleton has cleared 52,000+ vent systems since 2013, every one starting with a written price and ending with before-and-after images of the duct interior. Call (720) 315-7291 and a live person will answer, 24/7, to schedule your free estimate or answer questions about what we’ll find inside your run.
Littleton’s combination of mature cottonwood canopy, freeze-thaw cycles that crack exterior vent caps, and the lint-heavy loads generated by Colorado’s hard-water laundry produces vent blockages we document weekly in neighborhoods from Columbine Valley to Ken Caryl. In Willow Springs and Roxborough, we regularly see bird nests in capped terminations after spring migration. The 365-Day Done Right Promise applies to every cleaning: if airflow doesn’t test at manufacturer spec, we return and make it right, backed in writing on every invoice.
Tomas Reyes established CleanRun in 2013 under the Haven Standard after watching competitors quote $79 by phone and invoice $400+ on arrival. That practice doesn’t exist here. Haven Standard Clause 1 requires a written price before any work starts. No exceptions.
What Our Dryer Vent Cleaning Service Includes
Dryer Vent Inspection
Every cleaning begins with a full Dryer Vent Inspection using a borescope camera threaded through the duct run, the metal pathway that carries exhaust from your dryer to the exterior termination. We photograph the interior at the elbow behind the dryer, at mid-run joints, and at the exterior cap, documenting lint density, moisture staining, and structural damage before proposing any work. In Littleton’s Ken Caryl Ranch, we inspected a vent last March that showed 4 inches of packed lint at the second elbow, the result of a previous “cleaning” that never advanced past the first 3 feet. The photo record becomes your property, delivered with the written scope.

Vent Cleaning
Vent Cleaning is the mechanical removal of lint and debris from the full length of the duct run using negative-pressure extraction, a sealed suction method that pulls debris toward a collection unit rather than blowing it into your laundry room. Our crews use Nikro equipment paired with rotary brush systems sized to your duct diameter, 4-inch rigid metal or semi-rigid flex, never compressed air alone. We clean from both terminations when accessible, verifying airflow with an anemometer before and after. A typical single-story vent in Littleton’s Columbine Knolls runs 12-18 feet; two-story runs in Heritage West often exceed 35 feet and require additional access points.

Lint Removal
Lint removal addresses the combustible fiber accumulation that escapes your dryer’s internal screen and adheres to duct walls, particularly at elbows and transitions where airflow slows. We remove lint from the full run, the transition hose behind the unit, and the dryer cabinet itself when accessible, using HEPA-contained collection to prevent redistribution. In Littleton’s older homes near Downtown, we’ve found lint packed with dryer-sheet residue that hardens into a shell, reducing airflow by 60% before the homeowner notices longer dry times. The photo record shows exactly what was removed and from which section.

Vent Rerouting
Vent rerouting relocates the exhaust pathway when the original design violates manufacturer safety guidelines or building code, such as runs exceeding 35 feet, more than four 90-degree elbows, or terminations beneath decks or into garages. We design a new route using rigid metal duct, the only material approved for concealed installations, with proper slope for condensation drainage. Last year in Littleton’s Broadmoor Bluffs, we rerouted a vent that terminated in a soffit, recirculating moist air into the attic and producing mold on the roof sheathing. The new route exited through gable end with a bird-guarded cap, and the photo record documented both the old hazard and the corrected installation.

Bird Guard Installation
Bird guard installation replaces standard vent caps with screened terminations that block nesting while maintaining proper exhaust flow, critical in Littleton where house sparrows and starlings colonize uncapped vents from March through August. We measure your duct diameter and install guards compatible with your siding type, verifying that the screen mesh meets NFPA 211 clearance standards and won’t clog with lint. In Roxborough Park, we install guards with removable screens for annual cleaning access, since the area’s piñon-juniper woodland attracts persistent cavity nesters. Every installation includes a written 5-year warranty on materials and workmanship.

Vent Cap Replacement
Vent cap replacement addresses cracked, missing, or improperly sealed terminations that allow water intrusion, pest entry, and backdraft of cold air into the duct run. We match replacement caps to your siding profile and duct diameter, sealing the penetration with proper flashing to prevent the freeze-thaw damage common in Littleton’s elevation-driven climate. In neighborhoods like Columbine Valley and Bow Mar, we see original caps from 1990s construction that have lost their damper flaps, creating a direct thermal bypass. The replacement is photographed before sealant application and after, with the written scope noting manufacturer and model.

Brands We Service for Dryer Vent Cleaning

CleanRun technicians are trained on vent configurations for all major dryer manufacturers, with specific expertise on systems paired with Honeywell whole-house ventilation controls and Aprilaire humidity management equipment. We’ve serviced hundreds of Honeywell-integrated installations in Littleton’s newer construction, particularly in Sterling Ranch and Terrain, where the vent system communicates with the home’s central air handler. Our crews carry replacement sensors and know the calibration sequence for these integrated systems, documented in the photo record if accessed.
We also maintain Abatement Technologies HEPA containment equipment for jobs where vent damage has released lint into wall cavities or occupied spaces, a scenario we’ve encountered in Littleton’s remodeling market where drywall repairs expose deteriorated ductwork. Whether your dryer is a standard residential unit or connected to a whole-house system, we can service the vent configuration. Bring us any make, any model, any year.

AfterSigns You Need Dryer Vent Cleaning Right Now
- Loads take more than one cycle to dry. When a standard cotton load requires 70+ minutes, restricted airflow is the likely cause, not the dryer’s heating element. We measure exhaust velocity at the exterior cap; readings below 15 MPH at the termination indicate blockage requiring cleaning.
- The laundry room feels humid or smells of lint during operation. Moisture and odor escaping the duct run signal a breach in the transition hose, a disconnected joint, or backpressure forcing exhaust through gaps. In Littleton’s dry climate, this symptom often appears before the homeowner notices longer dry times.
- Visible lint accumulates around the exterior cap or behind the dryer. Lint escaping the system means it’s not being carried to the termination, either from overload or partial blockage. We photograph these escape points during inspection to trace the source.
- The exterior cap’s damper barely opens or stays closed during operation. A properly functioning vent produces steady damper movement you can observe from outside. Static or minimal movement indicates airflow restriction, often from lint packed at the termination or a bird nest in the cap.
- It’s been more than 12 months since professional cleaning, or never. The Consumer Product Safety Commission recommends annual inspection for households doing 5+ loads weekly. In Littleton’s hard-water areas, mineral-laden lint adheres more aggressively to duct walls, accelerating buildup compared to soft-water regions.
Our Dryer Vent Cleaning Process - Step by Step

- 1
Arrival and written price confirmation. The technician introduces themselves by name, verifies your appointment details against Haven Standard Clause 3: Verified Crews, and presents a written price for the agreed scope before touching equipment. No work begins without your signature on the scope.
- 2
Borescope inspection and photo documentation. We thread a camera through the full duct run, capturing the condition at each joint, elbow, and the termination. These images display on a tablet you can review; they become the “before” record in your job documentation.
- 3
Mechanical cleaning with negative-pressure extraction. Using Nikro rotary brush systems and sealed suction, we clean from the dryer connection to the exterior cap, sizing brushes to your duct diameter to prevent damage to flex duct or joint seals. Debris collects in a HEPA-filtered container, not your laundry room.
- 4
Airflow verification and component testing. We measure exhaust velocity at the termination with an anemometer, comparing against manufacturer specifications for your dryer model. The exterior cap damper, transition hose, and clamps are inspected for integrity.
- 5
Photo record delivery and written warranty. The “after” images are captured, compiled with the “before” set, and delivered as your Documented Photo Record. The 365-Day Done Right Promise is printed on your invoice, with Tomas Reyes’s direct contact for any concern.
How Much Does Dryer Vent Cleaning Cost in Littleton?
A standard single-story dryer vent cleaning in Littleton runs $150-$220; see our Dryer Vent Cleaning cost guide for full pricing details, depending on duct length, accessibility, and lint density. Two-story homes with roof or soffit terminations, common in Heritage and Willow Springs, typically range $220-$350 due to ladder work and extended hose requirements. Vent rerouting, when code violations require redesign, starts at $400 and is quoted only after inspection and photo documentation.
Several factors affect your specific price. Duct material matters: rigid metal cleans efficiently; damaged flex duct may need replacement at $8-$12 per linear foot. Termination height adds labor for second-story and roof exits. Bird nest removal, when we encounter active nesting, requires additional containment and sanitizing per Colorado Parks and Wildlife guidelines. We disclose all variables in writing before work starts, under Haven Standard Clause 1.
The $79 coupon model works by arriving with a higher invoice prepared. CleanRun doesn’t operate that way. The price we write is the price you pay, inclusive of the photo record, airflow testing, and warranty documentation. No per-vent pricing exists for dryer vents; there’s one system, one flat price.
To avoid overpaying, request that any competitor specify in writing: whether they clean the full duct run or just the first few feet, whether they photograph the interior, and whether their quote includes the transition hose and cabinet. Most cannot answer affirmatively. CleanRun does, on every job, and provides a Free Second Opinion on any written estimate you bring us.

Frequently Asked Questions - Dryer Vent Cleaning in Littleton

Dryer vent cleaning is the mechanical removal of lint and debris from the metal duct that carries exhaust from your clothes dryer to the exterior of your home. It matters because lint accumulation restricts airflow, forcing longer dry cycles and creating fire risk; the National Fire Protection Association identifies clothes dryers as a leading cause of home fires, with failure to clean as the primary factor. CleanRun’s process includes borescope inspection, rotary brush cleaning, and airflow verification with documented photography of every stage. Call (720) 315-7291 for a free estimate.
A standard cleaning takes 60-90 minutes from technician arrival to photo record delivery, assuming accessible ductwork and no structural repairs needed. Complex jobs, two-story terminations, or rerouting requirements may extend to 2-3 hours, always with the revised scope presented in writing before additional work proceeds. We schedule appointments with arrival windows, not vague “morning” or “afternoon” blocks. Call (720) 315-7291 to check this week’s availability in Littleton.
Most Littleton homeowners pay $150-$220 for standard single-story vent cleaning, with two-story or roof-termination jobs at $220-$350. Rerouting, cap replacement, or bird guard installation are quoted after inspection with written pricing before work begins. The estimate is free, the price is flat per system, and the photo record is included at no additional charge. Call (720) 315-7291 for your specific quote.
Yes. We clean vent configurations for all residential dryer manufacturers, with specific expertise on systems integrated with Honeywell and Aprilaire whole-house controls common in Littleton’s newer construction. The vent duct is independent of the dryer’s internal components; our service addresses the exhaust pathway, transition hose, and termination, regardless of appliance brand or age. Call (720) 315-7291 if your system has specialized ventilation controls.
We do not advertise same-day or emergency dispatch for dryer vent cleaning. This is scheduled maintenance, not an acute repair, and we maintain consistent route density rather than on-demand premiums. If you’ve discovered a blocked vent creating immediate hazard, call (720) 315-7291; our live answering service will triage and expedite if warranted, with transparent timing and no urgency surcharge.
Every cleaning is backed by the 365-Day Done Right Promise: if airflow doesn’t meet manufacturer specification or lint remains visible in the photo record, we return and correct the deficiency at no charge. This is a written guarantee on your invoice, not a policy subject to manager approval. Bird guard installations carry a separate 5-year materials and workmanship warranty. Call (720) 315-7291 with any concern within the coverage period.
Clear a 3-foot workspace around the dryer, remove items from the top and front of the unit, and ensure pets are secured in another room. The technician needs access to the exterior termination, so unlock gates or note access codes. You do not need to move the dryer; our crews handle repositioning with protective floor covering. Have any previous service records available if you’d like us to compare against prior findings. Call (720) 315-7291 when you’re ready to schedule.
