THEY ARE CONTRACTED WITH THE WORST PEOPLE EVER! Service One has some of the worst contractors I have every worked with and when it comes to getting someone back out to fix a problem that wasnt fixed the first six times good luck. They will be quick to try and collect their $55 fee every time as well. They wouldnt be so bad if they actually worked with people who could get the job done. Your better off putting your $500 bucks in a "oh shit" bucket.
