Step 1: Have a garage sale, if you have some good stuff. Anything that you can even give away, you don’t have to pay to throw away.
Step 2: Donate any usable items, or offer them on Craigslist or Facebook Marketplace.
Step 3: Put trash into as few piles as practical to determine how much trash you have. This will help in determining what size dumpster you will need. Trash always looks like less when it is spread out. Do not under-estimate. The cost for a slightly larger dumpster is much less money than that to rent a second dumpster of any size.
The most common sizes are below:
10yd (11’L x 7.5’W x 4.0’H), great for a bathroom renovation, or small cleanout.
15yd (15’L x 7.5’W x 4.0’H), an option for a small kitchen, or a small cleanout.
