Smoke damage restoration in Milan, MO for residue you can see and odor you cannot escape

How smoke moves through a home

Smoke behaves like a hot gas. It rises, spreads along ceilings and pushes toward cooler areas, following openings such as stairwells, attic hatches, electrical boxes and gaps around pipes. As it cools, particles settle on surfaces and cling to anything with texture. A small fire in one room can leave residue in closets, cabinets and the attic on the other side of a Milan, MO house. The HVAC system can carry it further if it ran during or after the fire.

Smoke damage also happens without a fire inside the home. A furnace or boiler malfunction can release a burst of soot called a puff back. A candle left burning can blacken a ceiling. Smoke from a neighboring structure fire can enter through vents and open windows.

Reading the residue

Before cleaning, our technician tests surfaces to see what kind of residue is present. Dry residue from fast burning materials wipes away more easily. Oily or wet residue from plastics and smoldering fires smears and needs degreasing products. Protein residue from burned food may be almost invisible yet carry a strong, persistent smell. Fuel oil soot from a puff back is heavy and greasy. Test spots tell us which method will lift the residue without spreading it.

Common signs of residue include gray or yellow film on walls, dark outlines where air flowed past a doorway, shadows on ceilings above lights and vents, and discoloration on plastic outlet covers and appliance housings.

Cleaning surfaces and air systems

Loose particles come off first with HEPA vacuuming. Dry chemical sponges then lift residue from flat paint and ceilings. Washable surfaces are cleaned with solutions suited to the residue type. Textiles such as curtains and bedding may go to specialized cleaning. Because ductwork can hold residue and redistribute odor each time the system runs, we inspect the HVAC system, replace filters and clean the ducts when contamination is found.

Some surfaces cannot be cleaned to an acceptable result. Porous ceiling texture, insulation with embedded odor and heavily stained drywall are removed and replaced by our Drywall Repair crew.

Removing odor, not covering it

Smoke odor comes from particles and compounds lodged in materials. Air fresheners only hide it for a while. Lasting deodorization combines source removal, thorough cleaning, sealing of surfaces that retain odor with a primer made for the purpose, and air treatment. Hydroxyl generators can run while people are present; ozone treatment requires the space to be empty because ozone irritates the lungs, a caution the EPA emphasizes.
