Suck Out Insulation
Tearing down a drywall ceiling is not a super-pleasant experience, but tearing down a ceiling that has 14 in. of blown-in insulation on top of it is a complete nightmare. Avoid that gigantic mess by sucking out all the insulation in the attic before pulling down any drywall.
The huge vacuum required for the job costs about $220 a day to rent, but if your local rental center doesn't carry them, call an insulation contractor in your area. Many blow-in insulation installers also have the equipment to suck out the insulation. But this service isn't cheap: Expect to pay about $1 to $1.50 per sq. ft. You might be able to get a deal if you use the same company to blow in the new insulation. Make sure your insulation is fiberglass or cellulose. If you even suspect there's vermiculite insulation in the attic, get an expert opinion before touching the stuff—it could contain asbestos.
Cut It Up With a Circular Saw
Sledgehammers, pry bars and reciprocating saws aren't the only demo heroes on the job site—your circular saw can be used for a heck of a lot more than cutting studs and sheets of plywood. Fitted with the right blade, your circular saw can cut up roofing, tin, concrete, rebar, steel doors and fiber cement. With a demo blade, you can cut up nail-embedded debris all day long.
Rent a Walk-Behind Floor Scraper
Some old vinyl sheet or tile floors are super easy to pull up. Others are so thoroughly glued down that you're lucky to remove quarter-size chunks with every whack of your handheld floor scraper. If a shovel and hand scraper are just not getting the job done, rent a walk-behind scraper. For about $50 to $60 a day, you can save yourself a bunch of time and prevent a whole lot of wear and tear on your back and wrists. Many floor scrapers have an attachment for busting up ceramic tiles as well.
