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.

Why Cardinal Air Duct Cleaning Is Norwalk’s Preferred Air Duct Cleaning Company
We spend a lot of time in Norwalk, from the tree-lined streets near Cerritos College down to the 605 corridor by Santa Fe Springs. The homes here share something that shapes how we work: most were built between the mid-1950s and late 1960s, and their duct systems were installed when a 1,200-square-foot ranch with a wall furnace was considered modern. Those short, low-static runs need a different approach than the long, high-velocity ductwork in newer subdivisions. Our Air Duct Cleaning team knows the difference, and it shows in how we set pressure, select brush heads, and decide whether a camera inspection is necessary before any agitation begins.
Customers in Norwalk consistently mention two things in reviews: the written flat price they received before any work started, and the fact that the technician’s name and photo arrived before the tech did. Every booking runs on The Relay Standard – a live trackable arrival window, uniformed and background-checked techs, and photo documentation at the end. Omar Haddad leads the team, and the standard he set is simple: if it is not done right within 365 days, we come back and make it right at no charge. That promise covers every job in Norwalk, not just the ones that fit a promotional calendar.
Air Duct Repair in Norwalk
Air Duct Repair in Norwalk typically means sealing separated joints, patching cracked flex runs, or replacing collapsed sections in slab-embedded or tight attic chases. On a 1962 ranch off Pioneer Boulevard, that often means the return trunk has pulled away from the plenum after six decades of thermal cycling. Licensed duct repair in Norwalk runs $150 – $400 for standard joint resealing and flex patching, with full section replacement landing higher depending on access. We scope every repair with a camera first, so you see the problem before we touch it.
Slab and Tight-Chase Repairs
Norwalk has a lot of slab-on-grade foundations, and some supply ducts were run directly through the slab or in crawl spaces barely tall enough to turn a wrench. A crack in those runs is not something you fix by blasting a brush through it. We locate the exact section, camera it, and quote a flat repair price before anything is cut or resealed.
Mastic and Joint Failures
Old mastic dries out. It cracks. Air leaks rise and dust gets pulled in. In Norwalk’s aging tract homes, we regularly find return-side joints pulling 20 – 30% of their airflow from the wall cavity or attic instead of the conditioned space. Our repair work includes re-mastic on the joint, re-taping where needed, and a pressure test on the repair before we call it done.
Ductwork Cleaning in Norwalk
Ductwork Cleaning in Norwalk means cleaning the full system the way it was installed, not just the registers you can see from your hallway. For most Norwalk homes that means the supply trunk, return trunk, and every branch run between them. A flat-per-system cleaning runs $350 – $550 here, with commercial or larger custom homes running higher based on the number of systems, not the number of vents. We use negative-pressure extraction – that means the loosened debris goes straight into the vacuum, not back into your living room.
Camera-Verified Process
Before we agitate anything, we run a camera through the trunk and branches. On older Norwalk systems with aged flex connections, this step catches weak joints that high-pressure brushing would tear open. We document what is there, clean what is cleanable, and flag what needs repair instead of vibration.
Full System Cleaning with HEPA Extraction
Our trucks carry Nikro HEPA-rated vacuums and Abatement Technologies containment units. That means the air leaving your ducts during cleaning passes through HEPA filtration before it re-enters the room. We run Rotobrush rotary brush systems through the supply branches, then pull the return side under negative pressure so nothing escapes into the hallway.
Trusted Brands We Service in Norwalk
Most Norwalk homes were built with sheet metal trunk lines and flex branches, but plenty have been retrofitted over the decades with newer filtration and zoning components. We service and clean systems that use Aprilaire media cabinets, Guardsman filter housings, and standard residential flex from a range of suppliers. If your system has an Aprilaire filter cabinet, we can replace the media during the visit rather than sending you to a supply house. Our trucks carry common filter sizes and replacement access panels for Norwalk’s older floor-register systems, so the job does not stall waiting on a part.
Common Air Duct Cleaning Problems We See in Norwalk Homes
- Drywall dust packed in return trunks. Norwalk saw a huge wave of remodeling in the 1990s and 2000s, and contractors often ran sanding and cutting without sealing off returns. We regularly pull several pounds of fine gypsum dust from homes near Norwalk Boulevard and the 5 freeway that never saw a post-remodel duct cleaning.
- Rodent nesting debris in slab-adjacent returns. The crawl spaces and chaseways under older Norwalk homes are access points for rodents. Nesting material and droppings in the return run means the system circulates contaminated air. HEPA extraction and full containment are required, not a shop-vac pass.
- Cracked flex from aggressive past cleanings. We have repaired enough torn flex in Norwalk to know what high-pressure agitation without an inspection first can do. Aged flex splits, mastic joints pop, and air starts pulling from the attic. The camera inspection we run before cleaning catches this before we add pressure.
- Disconnected or sagging return branches. On homes near Artesia Boulevard and the older tracts east of the 605, we find return branches that have sagged or separated from the trunk entirely. That means unfiltered air is being pulled into the system from unconditioned space, and cleaning alone will not fix the leak. We flag it, quote it flat, and repair it if you want it done.
Pricing for Air Duct Cleaning in Norwalk, CA
A standard single-system air duct cleaning in Norwalk runs $350 – $550 as a flat price that covers the full system – supply and return – plus documentation. You get a written price handed to you before a single duct is touched, and it does not change at the door. Larger homes with two systems or long commercial runs run higher, but we quote the flat system price during the booking process, not after an inspection finds “extra vents.” We do not price per vent, ever. That model punishes Norwalk’s older tract homes that often have eight or nine registers on short runs. Estimates are free. Call (737) 727-2314 and get a written number before you commit.

FAQs About Air Duct Cleaning in Norwalk
We charge a flat per-system price in Norwalk, never per vent. A standard single-system home runs $350 – $550, and the written quote you get before work starts is the number on the invoice after. We do not add on per-register fees or “complexity” surcharges once the job begins. Call (737) 727-2314 for an exact flat quote on your system.
Most Norwalk homes benefit from a full duct cleaning every three to five years, but that changes with circumstances. Remodeling, pets, smokers, or a rodent issue in the crawlspace pull that timeline shorter. If you have not renovated and have no allergy symptoms, air pressure at the registers feels fine, and the ducts were cleaned less than four years ago, you likely do not need it yet. We will tell you that straight before we book anything.
We run a camera inspection first, then clean supply and return runs with Rotobrush rotary agitation under Nikro HEPA-filtered negative pressure. At the end you receive before-and-after photographs of your own registers and trunk lines, a written summary of what was removed, and a digital invoice payable by link. The whole thing runs three to five hours for a standard Norwalk single-system home.
Yes, and that is exactly why we do not run high pressure on Norwalk’s 1950s – 60s tract systems without a camera inspection first. The short, low-static runs on these homes often have aged flex connections and dried mastic that will tear under aggressive brushing. We match the tool and the pressure to what the camera shows, and we pre-flag any joints that need repair before we clean.
We do not promise same-day or one-hour duct cleaning, because a real cleaning with negative pressure, containment, and camera documentation takes three to five hours and is scheduled in advance. Same-day rush pricing in this trade often means a corner-cutting job. We schedule appointments at the next available slot and honor that window with a live trackable arrival time on The Relay Standard. Call (737) 727-2314 to find the soonest opening.
What Makes Norwalk Ductwork Different
Norwalk’s housing stock is dominated by 1950s – 60s tract homes whose original duct runs are short, low-static, and often buried in slab or tight attic chases. A camera inspection matters more here than raw cleaning pressure. Those systems share some of the lowest static pressures in the region, which means aggressive agitation can damage aged flex and mastic joints rather than help them. In the Keith Street tract near Norwalk High, our tech pulled several pounds of drywall dust and rodent-nesting debris from the return trunk of a 1962 ranch home that a previous “tune-up” had skipped entirely. Using negative pressure with HEPA filtration and Rotobrush agitation tools, we cleaned the supply and return ducts, resealed two separated joints, and handed the homeowner before-and-after photos of their own registers. That is the standard on every Norwalk job, not a special case.
