Odors are particles, not just air
Every lasting smell comes from something physical: residue on surfaces, contamination absorbed into materials, microbial growth or moisture trapped where it should not be. Air fresheners and fragrance sprays cover the smell for a while, but the source keeps releasing odor until it is removed.
Odor removal in Tamalpais-Homestead Valley, CA starts with investigation. We ask when the smell started, when it is strongest and what has happened in the building recently. Then we look for the source using moisture meters, visual inspection and, frequently, our noses.
Common odor sources
Smoke odors come from residue on walls, ceilings, fabrics and inside ductwork. Sewage and damp odors come from contaminated or wet materials, often under flooring or inside wall cavities. Musty smells usually point to hidden moisture and microbial growth. Pet urine penetrates carpet, pad and even subfloor. Decomposition odors from animals that died inside walls or crawlspaces require locating and removing the remains.
Each source calls for a different response. Sometimes the fix is cleaning. Sometimes it is removing and replacing a section of carpet pad, subfloor or drywall. Sometimes it is drying a hidden wet area. Treatments only work after the source is dealt with.
Neutralizing what remains
Once the source is removed or cleaned, we treat the remaining odor with methods suited to the space and the type of smell. These include thermal fogging, which penetrates materials in a similar way to smoke, hydroxyl generators that break down odor molecules and can be used in occupied spaces, and sealing primers for porous framing or subfloors.
We also clean or replace HVAC filters and clean ductwork when odor has spread through the system. The result should be a neutral-smelling space, one where you stop noticing the air entirely.
