We Eliminate It. We Don't Cover It Up.
If you've tried air fresheners, candles, ozone machines, or professional carpet cleaning and the smell keeps coming back, you're not alone, and it's not your fault. Those solutions treat the air, not the source. Odor-causing compounds from smoke, urine, mold and biological materials embed deep into drywall, insulation, upholstery, carpets, HVAC ductwork, and even the wood framing of your home. Until those compounds are neutralized at a molecular level, the odor will always return.
At Odor Removal Services Denver, we start by finding the odor source, then choose the treatment that fits it: source removal, bio-enzymatic treatment for organic sources like urine, cleaning and sealing, HVAC work, or a controlled chlorine dioxide vapor treatment for odor held in porous materials. The goal is a space that smells neutral, not like a plug-in air freshener.
We're a locally owned Denver company, proud to help homeowners, landlords, real estate agents and businesses reclaim their spaces from stubborn odors. Whether you're dealing with a home that smells like the previous owner's cat, a car that reeks of cigarette smoke, or a rental unit left in rough condition by a tenant, we build a treatment plan around what our assessment finds.
An Odor Shouldn’t Cost You the Sale
A Real Estate Reset is an odor assessment and treatment plan for a property changing hands. It helps sellers, agents and managers address a concern before photos, showings or a new occupant arrives, without promising a sale or a particular outcome.
When a whole-house reset makes sense
Consider one when cigarette smoke, pet accidents or cooking odors affect several rooms, or when a long-vacant home or rental has an odor that cleaning has not resolved. A small, isolated source may only need targeted work.
What the scope can include
We look at the likely source, affected rooms, carpet and padding, subfloors, walls and air pathways. Depending on what we find, the plan may call for source removal, surface cleaning, material replacement or sealing, and controlled odor treatment. Not every home needs every step.
Planning for the next showing or occupant
Homeowners can plan work ahead of listing photos. Realtors can coordinate access and share the scope with sellers. Property managers can schedule around cleaning, flooring and tenant turnover. We explain any vacancy, ventilation and re-entry requirements before work begins.

Whole House Reset for Odor Removal
ClO2 / Chlorine Dioxide whole house odor removal for homeowners and realtors.
The Whole House Reset is a property-wide assessment and treatment plan for odors affecting multiple rooms or materials. Depending on the source, work may include source removal, cleaning accessible surfaces and a controlled chlorine dioxide treatment. Saturated materials and ongoing moisture problems may require separate repair or replacement.
For homeowners, the Whole House Reset is a fresh-start treatment for stubborn old-house smell, lingering smoke, pet odor history, moisture, and the kind of move-in or move-out odors that ordinary cleaning cannot reach.
For realtors, it's a pre-listing and post-occupancy solution that removes odor objections before showings and inspections, making the home show-ready fast with a clean, professional, market-ready result.

Problems it solves
- Old-house smell that won't go away
- Heavy smoke or tobacco history throughout the structure
- Multi-room pet odor and urine saturation
- Musty moisture and basement odors that have spread upstairs
- Move-in / move-out odor resets
- Pre-listing whole home odor removal for realtors
How ClO2 treatment works
Chlorine dioxide is a professional-grade oxidizer that converts to a vapor and reaches every surface, void, and HVAC pathway in the home. It chemically destroys odor compounds at the source rather than covering them with fragrance. The treatment is controlled, contained, and applied only by trained technicians, with a clear pre-treatment prep, dwell, and ventilation process before the home is cleared for re-entry.
When to use the Whole House Reset
- Buying or selling a home with odor concerns
- Pre-listing odor removal before photos and showings
- Post-tenant turnover in rental properties
- After fire, flood or smoke damage cleanup
- Inherited or estate properties with decades of odor history
- Any home where room-by-room treatment isn't enough
Safety & process
ClO2 is a powerful treatment and we treat it that way. Our process includes an assessment, written scope, pre-treatment prep, controlled application, dwell time and ventilation before re-entry. People, pets and plants stay out of the treated space during dwell. We explain the re-entry requirements for the chosen treatment.

Inspection & Assessment
A thorough walkthrough to identify odor sources, assess penetration depth, and evaluate affected surfaces. You get a clear, honest quote before any work begins.
Surface Treatment
We apply our EPA-registered, bio-enzymatic neutralizers directly to carpets, flooring, walls and upholstery, breaking down odor molecules on contact.
Whole-Space Vapor Treatment
Our odor-neutralizing agents are delivered into the air, reaching HVAC vents, wall cavities and every corner that surface treatment can't access.
Dwell & Re-entry
We allow the specified dwell time, ventilate as required and explain re-entry steps before the space is used again.

Frequently Asked Questions About Odor Removal in Denver CO
How much does odor removal cost in Denver CO?+
The cost depends on the size of the area, the type and severity of the odor, and the number of treatments required. Call (720) 263-6069 or fill out our contact form for an honest quote.
How long does odor removal take?+
Most residential treatments take 1 to 4 hours to perform, plus a dwell time of 4 to 24 hours before the space is ready for normal use. Vehicle treatments are typically completed in 1 to 3 hours. We'll give you a specific estimate when we assess your job.
Will the odor come back after treatment?+
When the source is removed or fully treated, the odor should not return. Results depend on the source, how long it was present and which materials absorbed it, and some heavily saturated materials need to be replaced or sealed. We tell you what is realistic after our assessment and check results before we call a job done.
What about kids and pets during treatment?+
Children and pets must stay out of treated areas during active treatment. For vapor treatments such as chlorine dioxide, people, pets and plants leave the treated space, and the area is ventilated before re-entry. We give you written prep and re-entry instructions for your specific treatment and tell you when the space can be re-occupied.
How is this different from ozone treatment?+
Ozone can reduce some odors, but the EPA notes that concentrations effective against odor exceed public health limits, so spaces must be unoccupied, and ozone can degrade rubber, plastics and some finishes. Results can also be limited when the source is still present in porous materials. We choose between source removal, bio-enzymatic treatment of organic sources and controlled chlorine dioxide treatment based on what our assessment finds.
Do I need to leave my home during treatment?+
For whole-home vapor treatments, we typically ask residents to be out of treated areas for 4 to 8 hours while the product works and the space ventilates. Most homeowners find it easy to run errands or visit family during this time.
Do you serve areas outside of Denver?+
Yes. We serve Denver and the surrounding metro communities listed on our service areas page, including Aurora, Lakewood, Arvada, Westminster, Thornton, Wheat Ridge, Littleton, Highlands Ranch and Parker. For communities farther out, call us to confirm coverage. Reach out via our contact form to confirm your area.
