Smoke damage cleanup for Logan Square homes

A greystone on Logan or Kedzie Boulevard usually stacks two or three flats around a shared front stair, with a wooden rear stair or porch and often a garden unit below ^[2]. When one flat burns, smoke climbs the front stair into the flats above and drifts out through the rear porch enclosure. The garden unit may get little smoke but plenty of water.

That layout means smoke cleanup in a greystone almost always covers more than one household. Each flat off the affected stair is checked, along with the stair itself, the top-floor ceiling and the space under the roof.

Logan Square's greystones and large boulevard homes are known for original interiors: plaster walls and ceilings, oak trim, built-in buffets, pocket doors and sometimes leaded glass. Smoke film on these surfaces usually cleans well if it is lifted dry first and then washed with cleaners matched to the residue and tested on a hidden spot.

Old shellac and varnish finishes can soften under strong solvents, so restorers test before scaling up. Where heat has clouded a finish, refinishing gives a better result than scrubbing, and it avoids the lead hazard of sanding old paint layers unnecessarily ^[4].

Bucktown and the side streets of Logan Square have many older frame cottages and two-flats. Some are balloon framed, with studs running from the sill to the roof and no blocking between floors ^[5]. Smoke from a basement or first-floor fire can climb inside the walls and stain the attic without passing through a single room.

A careful contractor checks the tops of walls and the attic floor even when the visible smoke damage is downstairs. Residue in those cavities is a common reason a cottage still smells months after its rooms were cleaned.

Newer three- and four-story condo buildings near the Blue Line and along Milwaukee Avenue use drywall, engineered flooring and ducted heating and cooling in each unit. Smoke in these buildings spreads through corridors and the HVAC systems more than through stairs and wall cavities.

Drywall with smoke film can often be cleaned and sealed, but each unit's ductwork usually needs cleaning too. The condo association handles corridors and common elements; owners handle their own interiors under their unit policies.

Milwaukee Avenue's mixed-use buildings put restaurants and bars at street level with flats above. A commercial kitchen fire sends greasy protein residue up through the stair and floor into the apartments. It is lighter in color than soot but strongly scented and clings to cabinets, curtains and closet contents.

Apartments above a restaurant fire need degreasing on every surface the film reached, plus odor treatment. Each tenant documents their own unit, and the building owner and business deal with their own insurers.

The Logan Square Boulevards Historic District is a Chicago Landmark district as well as a National Register listing ^[1]. Cleaning smoke from inside a home there needs no special approval. Exterior work that requires a permit, such as replacing scorched windows or restoring the limestone front, may need review by the Commission on Chicago Landmarks ^[6].

Smoke-stained limestone can usually be cleaned with methods suited to the stone. Acidic cleaners and harsh pressure washing damage it, which in a landmark district can also complicate approvals.

Garden units are the one place in a greystone where smoke and water problems usually meet. The unit may hold residue that drifted down the stair, plus firefighting water that drained from above. Drying comes first, because cleaning wet plaster smears residue and traps moisture.

Once the unit is dry, smoke cleaning proceeds normally. Belongings stored there, often in basement storage areas, need to be checked for both smoke and water damage.

In an owner-occupied two-flat or greystone, the owner may be dealing with their own flat, a tenant's flat and the common areas at once. The Illinois Department of Insurance recommends photographing damage before cleaning and keeping damaged items for the adjuster ^[7]. Tenants' belongings fall under their own renter's insurance.

A single cleanup plan for the whole building, shared with each household's insurer, usually moves faster than separate contractors working unit by unit.

Older Logan Square buildings benefit from a wiring inspection after any fire, since many fires in vintage flats start electrically. Working smoke alarms on every level, including the garden unit and basement, give everyone in a stacked building more warning.

Keep the front and rear stair doors closing properly; a door that latches slows smoke moving from one flat to the next.
