I only cleaned it out by ordering dumpsters and tossed out garbage and ceiling debris.

They are basically throwing spaghetti on the ceiling to see what sticks - only their hands are so sticky with so many hands in the pot, the entire ceiling is crashing down.

There were many challenges that came about after the inspection; from outlets that were not up to code, possible water leaks above the shower head in the ceiling, water pipes from bathroom vanity was the same as kitchen sink with no shutoffs, etc.

It's inspiring to know the ceiling and to have a lofty goal to shoot for but also a metric for success that is modest. edit: we are only looking at multifamily, not sfh.

This may involve installing drywall, flooring, and ceiling materials, as well as painting and decorating to your taste.

I have had to kilz paint ceilings, floors, and sometimes even remove Sheetrock and floors of people who were illegally smoking in units as opposed to people with pets In their units where I have had no issues.

Cabinets went up to the ceiling which gave them a place to hide and nest.

We designed the hot tub room to be well ventilated & have never had any sign of mold or staining on the walls/ceilings, but I did use a commercial exterior paint on all walls & the ceiling.

I have experience as an HVAC technician so I am relatively familiar with the constraints of renovating near or around HVAC systems, how much space is needed if walled off, ventilation requirements, etc. but I am sure there would be other issues like needing a larger window for egress and needing to do a window well, needing a drop ceiling to cover pipes in an already short basement, etc.

Expect a new roof, scrape the ceiling, new flooring, sub-flooring, and update electrical, many repairs are the reflection of water damage over time.
