Criminally negligent, this company has zero business claiming to be a snow removal company. They'll steal hard working people's money, won't even bother to show up to shovel the snow, then, lie to you, saying "We were there, we took care of it"-Flat out liars. Furthermore, I live in a 55 and over complex, every time it snows, my neighbors are struggling to get to their cars, slipping on ice, it's crazy! Yet, year after year, our hoa's management company hires them, I'm certain someone is getting a kick-back.

Do yourself a favor, don't even consider hiring these criminals. And, if you're shopping for a condo, ask who handles snow removal. If it's Quinn, buy another condo in another location. I can't stress this enough-Don't do business with Quinn! By the way, these photos were taken the day after the snowstorm last week, and the night after the most recent snowstorm, plenty of time for a reputable company to remove snow

Critical: Professionalism, Value THEY RAN OVER MY DOG LEASH LAYING ON MY SIDEWALK ATTACHED TO MY PORCH, HIT MY CAR (WHICH ISNT A CHEAP, INEXPENSIVE CAR)! THEY ALSO HAD THE NERVE TO TAKE THE EVIDENCE AND NOT EVEN LEAVE ME A NOTE OR ANYTHING SAYING SORRY, EXPECTED ME NOT TO NOTICE WHEN I GOT HOME! OWNER DOESNT WANT TO DO ANYTHING ABOUT IT. TERRIBLE BUSINESS.

I like in Oakhills at 7920 W Lakeview Ct. Palos Height, IL. You're employees block not only my driveway, but also the senior citizens driveways who live here. They even leave left over product and tree limbs on the driveway. It repeatedly happens no matter how often they are asked by my association and the police to stop. It is disrespectful. Please control you workers before I need to escalate this situation to the town and Congress. I have taken pictures if you want proof.

Had several quotes for completing the landscaping and patio at my home. Couldn't be happier with William Quinn & Sons. Not only was the quality even better than expected, but the communication and recommendations throughout the process were great! Have and will continue to highly recommend.
