The paths smoke takes in this kind of house

Warm air rises, and tobacco smoke rides it. In a two-story plan with an open foyer or a great room that rises to the second floor, smoke drifts up into the landing, the loft and the bedroom hallway. The upper walls and ceilings in those spaces collect a yellow-brown film that looks like ordinary dinginess until it is wiped with a damp white cloth.

The air system spreads it further. Most homes of this era have one furnace with returns in hallways or at the base of the stairs. The return pulls air from wherever smoking happened, passes it through the filter and blower, and pushes it out to every supply register. Over years the inside of the return duct, the blower wheel and the supply trunks pick up a coating that releases odor every time the system starts.

Gaps do the rest. Smoke follows pressure differences through electrical outlets, around recessed lights in vaulted ceilings, up plumbing chases and into attic space. Closets with closed doors often smell strongest because residue settled on stored items and walls and never got aired.

Matching the treatment to where the smoke went

  • IfThe white-cloth test turns yellow on ceilings in rooms far from where smoking happenedThenPlan for whole-house wall and ceiling cleaning, not just the smoker's room.
  • IfOdor surges when the furnace or air conditioner fan startsThenInclude the air handler, coil and duct interiors in the scope, and replace the filter before and after.
  • IfClosets and cabinet interiors smell stronger than the rooms around themThenEmpty them, clean all interior surfaces and consider a sealing primer on closet walls.
  • IfCarpet was replaced but the smell remains near the floorThenResidue may be on the subfloor or tack strip. Ask whether the subfloor should be cleaned and sealed under the next carpet.
  • IfOdor lingers around recessed lights or ceiling fansThenSmoke may have reached the attic or ceiling cavity. Ask a provider to check above the ceiling where it is accessible.

Surfaces that are easy to leave out of a smoke scope

  • Window blinds, window tracks and the tops of window frames
  • The underside of the stair landing and the stair stringers
  • Ceiling fan blades and light fixture globes
  • Inside the furnace cabinet and the return plenum
  • Interior faces of kitchen and bath cabinet boxes
  • Garage walls if a smoker used the garage with the door to the house open
  • Switch plates and outlet covers, which are best removed and washed

Questions to put to an odor provider about smoke

  1. Will walls and ceilings be cleaned before any sealing or deodorizing step?
  2. How will the ductwork and air handler be handled, and by whom?
  3. Which rooms are in the scope, and why were any left out?
  4. How long must the house stay unoccupied after each treatment step?
  5. How will results be checked, and what happens if odor returns after the house warms up in summer?

Common questions

Is fresh paint enough to cover smoke residue?

Usually not. Residue left on walls can bleed through standard paint as yellow staining and odor. Cleaning first, then using a sealing primer where staining or odor is heavy, holds up much better.

Do I need to replace the ductwork?

Not usually. Metal ducts can often be cleaned. Flexible duct with a fabric or plastic liner that is heavily contaminated is harder to clean, so ask whether replacing those runs makes more sense.
