Mark and his son are amazing. they will call if they would run behind. Mark always double check with me before he leaves. I have tried to shampoo my carpets on my own with a rug doctor and even after 5 hours of trying I wouldn't be able to get the clean results like he does in 30 mins. This business is a quality one, and I feel comfortable with them in my home and never worry about my valuables. I will always use Mark carpet cleaning! I HIGHLY RECOMMEND
