When my mom started getting older, she needed an agency to come into the home to provide care giving services. When they came to do an assessment, we were told that the clutter needed to be removed before they'd be willing to do the job. Given mom was in poor health, she needed someone else to do it, someone suggested a junk removal service.
We looked at homestars and decided on 1hrjunk. All we did was organize stuff into piles, put post it notes on the piles we wanted removed and watched/supervised the guys hauling it away.
I've seen ads for these companies before and always thought what a great idea it was. These guys did a great job and made what seemed like a really daunting task - simple as can be.
Would strongly recommend giving the clutter bug in your life the gift of a junk removal service :)
