Dirty Ducts.
Clean Air. Done Right.
After any fire, mold, water, or biohazard event — and for routine maintenance — contaminated ductwork spreads damage to every room it serves.
What We Do
Negative Pressure Duct Cleaning That Eliminates Contamination
Your HVAC system is the circulatory system of your building. After a fire, mold event, water intrusion, or biohazard situation, ductwork becomes a vector that distributes soot, mold spores, and contaminants to every room in the structure. Cantt Restoration provides thorough air duct and HVAC cleaning using negative pressure and contact cleaning methods that meet NADCA standards, protecting indoor air quality and preventing secondary contamination from spreading restoration gains. Do not run fans or your HVAC over wet or contaminated materials — call us first.
Pre-Cleaning System Assessment
We inspect the duct system, identify contamination type and extent, and determine the appropriate cleaning method before any equipment is deployed — the right method depends on what is actually in the system.
Negative Pressure Cleaning
We create negative pressure in the duct system to capture loosened debris and contaminants directly into collection equipment — debris does not re-enter living spaces during the cleaning process.
Contact Cleaning of Duct Surfaces
We mechanically clean duct surfaces using rotary brushes, air whips, and contact vacuum tools to remove adhered contamination — soot, mold, dust, and biological material that negative pressure alone cannot dislodge.
HVAC Unit Cleaning
We clean evaporator coils, blower assemblies, and drain pans — components that harbor mold and contamination that recirculates through the system if not addressed alongside the ductwork.
Antimicrobial Application
Where appropriate, we apply EPA-registered antimicrobials to interior duct surfaces following mechanical cleaning, reducing microbial growth in the system after a mold or water event.
Post-Event System Evaluation
After fire, mold, or water events, we assess whether the HVAC system can be cleaned to an acceptable standard or requires component replacement — and we document that assessment for your insurance claim. Content restoration of any salvageable HVAC components is always pursued before recommending replacement.
Immediate Steps
What You Should Do Right Now
- 1 After any fire, smoke, mold, or water event — turn off your HVAC system immediately. Running the system distributes contamination to every room it serves and significantly expands the scope of damage. No fans. No HVAC on wet or contaminated materials.
- 2 Do not run portable fans through the duct system or over contaminated materials. Contamination follows airflow — fans spread soot, mold spores, and biological material faster than any other single mistake at a loss site.
- 3 Video the system's condition before any cleaning begins — video first, then photograph. Capture register covers, visible duct interiors at accessible points, and any obvious contamination at the HVAC unit. This documentation supports your insurance claim.
- 4 Call Cantt Restoration at (903) 251-9525. We do not give estimates over the phone — we assess on-site and provide a scope based on what the system actually contains. We respond 24 hours a day.
Insurance & Documentation
How We Document It
Pre- and Post-Cleaning Visual Documentation
We photograph representative duct sections and system components before and after cleaning — a before-and-after record that supports both the work performed and the results achieved, formatted for your adjuster's review.
Contamination Type Documentation
We document the nature and source of contamination (smoke, mold, biological, etc.) and connect it to the primary loss event — essential for claim support when HVAC cleaning is part of a broader insurance loss.
System Condition Report
We provide a written assessment of system condition, cleaning outcomes, and any components requiring replacement, giving your adjuster a clear basis for the HVAC line items in your claim. HVAC cleaning after a covered loss is frequently a reimbursable expense that gets missed without proper documentation.
Why Cantt
Built Different. Independent.
Independent, Not Franchised
We clean HVAC systems as part of complete restoration projects — we understand how duct contamination connects to the primary loss and document it accordingly. Decisions are made by our crew, not a corporate call center.
Insurance Experience From Both Sides
HVAC cleaning after a covered loss is frequently a reimbursable expense that gets missed. Our staff includes former insurance adjusters who know to include it in the scope and document it properly so it does not fall off your claim.
Restoration-First Approach
We clean and restore HVAC components before recommending replacement — saving cost for you and your carrier while achieving the same clean-air outcome. We follow ANSI/IICRC S500, S520, and S700 standards on every job, and content restoration is always the first priority.
What Our Clients Say
Real Results
"After our house fire, Cantt cleaned our entire duct system as part of the restoration. The difference in air quality was immediately noticeable and they got it covered by our insurance. We had no idea that was even an option."— Carl J., Kilgore, TX
"Cantt found mold in our ductwork during a mold remediation job. They cleaned the ducts, documented everything, and our adjuster covered it without any pushback because the paperwork was so thorough."— Lynn A., Troup, TX
Questions
Frequently Asked
Do I need duct cleaning even if the event seems contained to one room?
If your HVAC system was running during or after a fire, mold event, or water intrusion — yes, in most cases. Your system does not respect room boundaries. A single return air grille pulls contaminated air from the affected room and distributes particulates throughout every room the system serves. The only way to know the extent of duct contamination is an on-site inspection. We assess before recommending — we do not give scopes over the phone because we cannot see your system remotely.
Will my insurance cover HVAC cleaning after a covered event?
In most cases, yes — when the contamination is directly caused by a covered loss such as a fire, water intrusion, or mold event, HVAC cleaning is a reimbursable scope item. The key is documentation: we document the contamination type, the connection to the primary loss event, and the cleaning outcome in a format your adjuster can use without requiring additional follow-up. Our staff includes former insurance adjusters who know exactly how this scope item is evaluated and what it takes to get it approved.
How long does duct cleaning take?
We do not give timelines over the phone — the duration depends on the size of the system, the type and extent of contamination, and whether the HVAC unit itself requires detailed cleaning. We assess on-site and give you a realistic scope and schedule based on what we actually find in the system. We work efficiently and do not leave equipment running unnecessarily in your home or business.
