What fire and smoke damage needs before repainting

First: safety and the insurance inspection

Nothing should be cleaned or painted until the fire department has released the house and your insurance adjuster has documented the damage. Cleaning first can make a claim harder, because the damage the adjuster needs to see is gone.

Take photos of every room before anything is moved, and keep receipts for any emergency work.

Remove what cannot be saved

Charred wood, blistered or soaked drywall and insulation that smells of smoke usually cannot be cleaned back to sound condition. These are cut out and replaced before any cleaning of the remaining surfaces, so you are not cleaning material that will be thrown away.

Structural framing that has charred needs an inspection and possibly a contractor or engineer before anything is covered up.

Clean the soot properly

Soot is oily and spreads well beyond the fire room. It is lifted first with dry chemical sponges, so it is not smeared into surfaces, then washed with a degreasing cleaner from the top down.

A simple check helps: wipe a white cloth across a cleaned wall. If it comes back gray, the wall is not ready to seal.

Treat the odor at its source

Smoke odor sits in porous materials and in the air system. Ducts, filters and contents are often handled by a restoration company with deodorizing equipment before painting starts. Sealing walls without dealing with the source only hides part of the problem.

Seal before you paint

Every smoke-exposed surface gets a shellac-based or dedicated smoke-sealing primer, including closet interiors and the backs of cabinets. Ordinary latex primer lets odor and stains pass straight through.

Rooms next to the fire room often need sealing too, even if they look clean, because smoke travels through doorways and wall cavities.

Then repaint, room by room

Only after cleaning, repairs and sealing does the finish paint go on, usually two coats wall to wall and ceiling to floor. Patching only the darkest areas leaves visible differences, because sealed and unsealed surfaces take paint differently.

A written room-by-room scope helps with your insurance claim and makes sure nothing is skipped.
