Communication was prompt and clear - early the next morning after I placed my inquiry. The estimate was given same day and the job completed the next morning. The job was removing an old fuel tank from the basement and was done at a very fair price.

"Good salesmanship and promises up front , high prices. Apparently it's a crapshoot what work crew you get. The crew I got did extremely sloppy work, made lame excuses for shortcuts they took and damage they did, needed constant supervision to check on the work quality, took triple the estimated work time, (promised 2 days, took 6 and kept us and our kids up until 10:30 pm the on last day because they had another job scheduled), and finally needed the intervention of a supervisor in order to finish with barely acceptable job quality with a gravelly mess left around my sliding door. They used property without permission. It was overall an unpleasant experience having them in my living space, I ended up having to move out until they were finished. I hope never to have to repeat that experience. Hopefully the work they did will be effective in keeping water out of my basement during any upcoming monsoon."

"Great experience. All staff were professional, respectful, and empathic. The staff all followed through with everything discussed and kept me informed every step of the way. The staff responded in a very prompt manner, and always with a positive professional manner. I would give them a 10 star on customer service if I was allowed, but the graph only allows a 5 star max. It has been a pleasure to work with this company and the people were real people, never felt like a number in their busy schedule. They went above and beyond in making a referral to another professional to assist us with another concern that did not relate to their work scope. I cant say enough about the politeness and responsiveness of all the staff which I came in contact with. It was a truely a pleasure interacting with Midstate Basement. I would recommend them to anyone who needs work done."
