"I hired Dana and his crew after he came out to my home and discussed a few details of what I needed done. We agreed on a price and Dana did not waste anytime and scheduled the job. Once he and his crew arrived they did not stop working for 2 days until the job was completed. I am extremely happy with the final result. I've had several people comment on the job and how solid it was. He built a nice 12 X 20 stone pad with 8X8 pressure treated wood. and filled with stone. He had to level the area and rip out some stumps. Now it's ready for the 10X18 shed which is going on the pad. Well done !!!!! Highly recommend !!!!!!"

"Bob was here when he said he would be, he kept me appraised of what he found on my sump pump when he worked on it in his shop. He rectified prior instlllation issues with the pump setup, with good ideas, (this is my 3rd pump) that I think will stop future pump failures. Very helpful and pleasant even when digging under the snow to find the end of the pipe. Price was very reasonable considering all the work he did, including his 2 trips to the house/shop time and the price of the new pump and supplies. Thank you Bob"

I purchased a condo about six months ago and have noticed a surprising number of cracks in the walls which are slowly getting worse. I'm concerned that this is more than just a house settling since the place was renovated 8 years ago not recently. Yesterday, I noticed that the ceiling on my second floor stairwell has started to separate at a joint. That could just be bad workmanship with the drywall but... A month or so ago, the town filled a sinkhole on the street near my condo. At the time, I didn't think anything of it. Now, my fear is that this worsened settling could be related. I walked around my condo today and found that there is a hole under one of the gutter drains, covered up by a splash guard. I can't tell if it goes very deep but again.. doesn't seem like a good sign. Rather than bring in a contractor to fix the drywall and cover up a potential problem, I'd like to determine if I have a bigg
