We have that issue, too, only it's the smell that lets us know as it's kind enough to back up into our crawl space...
We have a plumber here called Day and Night, and they charge a flat rate of $89 no matter the time of day (or night), weekend, etc. I love them dearly.
My neighbor who has the same issue throws a handful of rock salt down his toilet every night before bed this time of year and flushes a few times to get it in the 'right area' (how could you know?) and he hasn't had the problem in a while.
We have had a few yeas where we resorted to the root kill stuff you flush- there's an organic brand of it- and we've gone without a back-up for three years, knock porcelain!!
