Odor Removal (Smoke, Pet, Ozone)

Smells are stubborn because they live inside materials: carpet padding, drywall, subfloor and ductwork. Spraying a fragrance only covers them, while real odor removal finds the source, cleans what can be cleaned and seals what cannot. NorTech connects you with vetted independent cleaning companies who set their own price for the treatment.

Finding and removing the source of the smell

The first job is detective work: pet stains under carpet, smoke film on walls, a damp patch behind a cabinet. Cleaners test with moisture meters and ultraviolet lights, and they may lift flooring to check the pad. Once the source is found, it has to be cleaned or removed, because no machine can erase the odor of soaked padding. A thorough cleaner will tell you honestly if materials need to be replaced. Tell the provider where the smell is strongest and when it started, and show any past leaks, accidents or repairs, because the history often points to the source.

How ozone and hydroxyl treatments work

Ozone generators and hydroxyl machines break down odor molecules in the air and on surfaces. Ozone is powerful but harmful to people, pets and plants, so the home must be vacated during treatment and aired out afterward. Hydroxyl units are gentler and can run while some work continues. Sealers are used on stains that cannot be fully cleaned, to lock the smell beneath a barrier. Your provider will explain the safety steps before starting. A moisture reading in walls and floors helps rule out a hidden leak, which would bring the smell back no matter how well the surface is cleaned.

Preventing the smell from coming back

Odors return when the source is still there or when moisture remains in the structure. After treatment, good ventilation and dry air help. Smoke odor in HVAC ducts may need a duct cleaning, and pet odor in a subfloor may need sealing. Change the air filters and wash fabrics in the home. Ask the provider for a follow-up check a few days later to confirm that the smell has stayed gone. Change the HVAC filter after treatment and consider a duct cleaning for smoke odors, since ducts can recirculate the smell through every room.

Frequently asked

Odor Removal (Smoke, Pet, Ozone) — common questions

It can, especially for smoke and some pet odors, but it works best after the source has been cleaned. Ozone is unsafe for living things, so the home must be vacated during treatment.

A single room can be treated in a day, while a whole home takes longer. Airing out afterward adds time. Your provider will give a schedule. Heavy contamination or materials that must be replaced can add days, so ask for a timeline after the inspection.

Sometimes. If urine or smoke has soaked into pad, replacement is often the only reliable solution. A provider will tell you honestly when cleaning will not be enough.

Pets, kids and plants should stay away during ozone treatment and until the home is aired out. Ask your provider about timing and safe re-entry. Hydroxyl treatments can be gentler, but the provider will still explain who should stay out and for how long.

It can if the source or moisture remains. A follow-up inspection helps confirm that the smell is gone. If it does return, mention it quickly, because early retreatment is easier and often points to a missed source.

The 30-day workmanship warranty covers retreatment if the original odor returns because of the work performed. New smells from new sources are outside it.
