Soot removal in Preston Hollow homes

Soot is abrasive, and dragged across a polished floor it can scratch. So the first job is to vacuum with a HEPA machine and keep foot traffic off. On marble, limestone and travertine, acidic residue can dull or etch the surface if left too long, and some cleaners can do the same. Crews test first, and use pH-neutral products. Porous or honed stone can absorb soot, and it may need a poultice to draw it back out. Fireplace surrounds carved in limestone can be especially difficult, since soot settles into the detail, so ask for a specialist on any important piece.

Soot rises, and two-story foyers, coffered ceilings and tall stairwells all collect it at the top. Scaffolds or lifts may be needed indoors, which requires protecting stone and wood floors. Look for dark bands along cornices and on top of beams and light fixtures, which are easy to miss from below. Black, web-like strings in corners are soot, and they smear when touched. Cleaning runs from the top down, so anything falling lands on surfaces still waiting to be cleaned. Before scaffolding is taken down, go up or ask for close-up photos.

A fast, hot fire leaves dry soot, which often lifts with a vacuum and dry sponge. A smoldering fire leaves a smeary, sticky residue. Burned synthetic furnishings and plastics, including electronics, can leave oily, dark marks. A kitchen fire on a high-output range leaves a thin, greasy film. A large house may have all of these in different zones. The cleaning plan should change from room to room, and crews should be testing as they go, rather than using one product everywhere.

Plated plumbing fixtures, polished brass, iron railings and gilded mirrors can all be marked. Soot should not stay on them for long, but rubbing with a rough cloth can scratch. Crystal chandeliers may be taken down, photographed and cleaned piece by piece. Gilded frames and leaf should go to a conservator, since water and many cleaners can remove the gold. Silver can tarnish quickly, so wrap and move it soon. Keep metal polish out of the picture until the residue has been lifted.

Fine paneling has been finished by hand, and a harsh product may leave a cloudy or uneven mark. Dry methods come first, then mild products. Wire-brushed or reclaimed beams have a rough face that traps soot, and these may need vacuuming and brushing in the direction of the grain. Wood floors need soot taken off before anyone walks on them. If wood needs refinishing, ask for samples and a color match in writing before the job begins.

Silk and grasscloth wall coverings cannot be washed the usual way. Dry sponging may help, but some will need replacing. Drapery is generally taken down and sent to a specialist, and hand-knotted rugs should be rolled and sent out. Do not vacuum soot from delicate fabric with a household machine, as it can press soot into the fibers or blow it back into the room. Photograph patterns, and find any remaining rolls or order records so that they can be matched.

Older estates may have paint that contains lead ^[3], and old ceiling, flooring or pipe materials could contain asbestos ^[4]. Cleaning can usually go ahead, but sanding, scraping or demolition should wait for testing. Keep children and anyone pregnant away from dust. Ask your contractor how the area will be contained and cleaned. Keep the results with your records, as they may be needed by later trades.

Look at stone from a low angle in daylight, as dull patches show up well this way. Wipe a white cloth along ledges and tops of frames. Check drawers, cabinet interiors and the backs of doors. Ask for before and after photos by zone, and share them with your adjuster. If surfaces look clean but rooms still smell, see odor removal in Preston Hollow.

Soot can reach places that nobody thinks of right away. Walk-in closets, safe rooms, elevator shafts, laundry chutes, dumbwaiters and storage under the stairs can all hold it. Elevators in particular can move air between floors, so an elevator cab and its shaft may need attention from a qualified technician. Pool houses and garages may also have taken smoke. Go through each floor with the contractor, using a printed floor plan, and mark every room as cleaned or still to do. This simple sheet helps avoid the common problem of one forgotten room spreading soot back through the house once doors are opened and air systems restart.

Large pieces that cannot leave right away should be covered with clean plastic that does not touch delicate surfaces, and crews should clean around them with care. Tell the crew which pieces are fragile, and let a specialist decide when they can safely move.
