The short answer

Initial Assessment and Preparation

The first step is a thorough inspection of your home. The pros look for visible soot, check the HVAC system, and identify porous materials like drywall, wood, and fabric that may have absorbed the smoke. They also note any areas where the odor is strongest, such as near windows, vents, or walls.

Before any cleaning begins, the space is prepared. Furniture and belongings are moved or covered, and the pros may set up air scrubbers to filter the air. They also protect unaffected rooms to keep the smoke odor from spreading. This preparation helps the cleaning process be more effective and reduces the chance of recontamination.

  • Inspect all rooms for soot and odor sources
  • Check air ducts and filters for trapped smoke
  • Identify porous materials that may need deep cleaning or replacement
  • Protect unaffected areas with barriers or negative air pressure
  • Document the condition for your insurance records

Cleaning Every Surface

Cleaning is a detailed process. The pros wipe down walls, ceilings, floors, and hard surfaces with specialized cleaners that break down smoke residue. They also clean inside cabinets, closets, and other hidden spots where odor can linger. Upholstery, curtains, and bedding are either laundered or dry-cleaned if possible.

For items that cannot be washed, like books or electronics, the pros use methods like dry cleaning sponges or ozone treatment. The goal is to remove the oily film that smoke leaves behind. In some cases, the pros may need to replace items like carpet padding or insulation that hold the smell even after cleaning.

Using Ozone and Thermal Fog

Ozone generators and thermal foggers are common tools for odor removal. Ozone is a gas that reacts with odor molecules and neutralizes them, while thermal fog uses a heated solution to penetrate porous materials. Both methods are used in a controlled way, often while the home is empty, to avoid health risks.

These treatments can be very effective, but they are not instant. The pros may run ozone generators for several hours or days, depending on the severity of the odor. After treatment, the home is aired out to remove any residual ozone. This step is often combined with other methods for the right results.

Sealing and Replacing Materials

Some materials cannot be fully cleaned. In those cases, the pros apply a sealing primer to block the odor from escaping. This is common on wood beams, concrete, and drywall that have been exposed to heavy smoke. The sealer creates a barrier that traps the odor molecules inside.

If the damage is too deep, replacement is the only option. Drywall, insulation, and carpet may need to be removed and replaced. The pros will advise you on which materials can be saved and which should be replaced. This decision often depends on the extent of the smoke damage and the type of materials in your home.

Final Verification and Prevention

After the cleaning and treatment, the pros do a final check. They use moisture meters and odor detectors to ensure the smell is gone. They may also recommend air purifiers or dehumidifiers to help maintain good air quality. In humid climates, keeping humidity levels down can help prevent musty smells from developing.

You can also take steps to keep your home smelling fresh. Change HVAC filters regularly, clean surfaces often, and address any water leaks quickly. If you live in Columbus, keep your windows open on dry days to let fresh air circulate. These habits can reduce the chance of lingering odors in the future.

Frequently asked questions

How long does smoke odor removal take?

The time varies based on the severity of the smoke damage and the size of your home. It can take anywhere from a few days to a couple of weeks. The pros will give you a timeline after assessing the situation. Factors include the type of materials affected and the methods used.

Can I remove smoke odor myself?

You can try basic cleaning and airing out, but deep odor removal often requires professional equipment and techniques. Ozone generators and thermal foggers are not typical household items. If the smell persists after your efforts, it may be time to call in the pros for a thorough treatment.

Will my insurance cover smoke odor removal?

Policies vary, and your insurer decides what is covered. Smoke damage from a fire is often covered, but coverage for odors from other sources may differ. Check your policy and talk to your insurance company to understand your options. Documentation of the damage can help with your claim.
