Keep the old locks to reinstall if you ever have any additional contractor work done.

The only specific request they made was to have the plumber come back and reinstall the old faucet.

We got involved talking to the contractor and they wouldn't make it right (ie find other personnel to reinstall correctly) and so we agreed that they would remove their carpet and not invoice.

Between now and the original listing date, the house has had both power meters for the two units removed and, since the seller will not allow the meters to be re-installing until conditions are removed, we would basically have to purchase the property 'as is'...

I am looking for a company to replace gutter board and reinstall gutters.

The floor is out of level and there was some rot from a dishwasher leak over the years so I am pulling up the sub floor, sistering joists for a level floor, and re-installing. 

So that old slate may be in good shape, but ... at some points "most" of those roofs (not all) require you to remove the tiles, prep, install new underlayment or water barrier membrane, then re-install the tiles. 

You have to remove the old carpet, the old mat, get the floor completely clear and flat, remove the trim in the house, lay a new mat down(in most cases), put the laminate in, then reinstall the trim.

Makes sense, it took two weeks to fix and reinstall everything

Level 5 (and others, probably) make skimming blades up to 48" wide now, so going from a rough wall to a smooth wall isn't as difficult as it used to be.Skimming should also be cheaper than adding 1/4" drywall because it won't require buying custom sized door jambs (to accommodate the thicker walls), using box extenders for electrical, removing and reinstalling base/crown molding, or any of the other issues you might run into by adding a layer of drywall.
