"Damien came out and checked my unit and told me exactly what was wrong. The unit had a leak. He fixed the problem and checked back on several occasions to make sure that the unit was running properly ( never had a company to do a follow up like he did). Very impressed. He will be the only person that I will call for any future HVAC needs. Very professional and will highly recommend."

"I found him off Craigslist, I didn't find him on Angie's List. He did his thing, he was on time, but I thought he was outrageously expensive for what he did. I didn't know it was Mister Sparky. I went on to Craigslist and they had this one ad that didn't identify who they were. They just said that they were super cheap and the lowest cost etc etc etc. I called them up and I set up an appointment and then Mister Sparky rolls in to the driveway. I had no experience with Mister Sparky. He is the on time electrician. He showed up, he wasn't in the house for more than 50 minutes. All he did really was, he took a wall socket and turned it upside down. I had the polarity upside down, I didn't know it, it was a dimmer switch, a really simple job that he knew and I didn't know it. It was knocking off some wall sockets and then he installed a ceiling light fixture for me that I couldn't do because I just needed three hands and I didn't have them. So, he had the experience. That was all he did. He really just did practically nothing and he charged me $180. It was like $200 an hour. I live in Mount Pleasant. Mount Pleasant is on the Carolina coast here, north of Charleston. It has a lot of people like myself who aren't native to the area. Mount Pleasant in here is perhaps the state's most affluent suburb. It's a very popular place because of its proximity to the downtown of Charleston, with all those attraction for dining etc. The rest of the population kind of lives elsewhere. My experience and I've been here eight years, there is like a Mount Pleasant price and there is a price for rest of the people, wherever they live. That's the problem that you have. You mention that you live in Mount Pleasant and all of a sudden the price is, "How much?" You just have to kind of grin and bear it and shop around. That's just the way it goes around here. They think everybody is rich who lives in here. I pulled them off Craigslist. They didn't identify themselves. They rolled in the driveway and I got a $200 bill, I was a little bit shocked. It was $200 an hour. I was expecting a little over $100 or something, not even that much for what he did. They were on time."

"Austin did an awesome job with my bathroom remodel. He was great from start to finish. From setting the shower pan, doing detailed trim work and solving my plumbing and electrical needs. Austin was very knowledgeable of the work needing done and very personable. Will hire again for future projects."

"Mike and Crystal were very professional from the first phone contact through the completion of the work. They showed up on time, their work was neat and they worked very efficiently. My windows were in pretty bad shape. They really took their time and prepped them very well which showed in the finished product. When asked to redo or touch up anything it was done without question. In the end we received a very good paint job on a timely basis and at a competitive price. I have already recommended Mike's Painting to others in my neighborhood and would use him again for future painting needs.
