Introduction: I'll take each job seriously. No job too small. When I joined US Army I fixed helicopters. Attention to details is a must because lives of people depend on quality work. I carried this attitude to civilian life.

Val from CornerStone777 was excellent! He brought all of the tools and parts that he needed to complete my requests with him. I needed an overall tuneup of my John Deere Zero-turn riding mower, including a blade sharpening, steering adjustment, and repair of the blade height adjustment controller. Val took care of all of the requested services plus changed the oil and filter, cleaned the mower and left it not purring but ROARING. The mower has been tuned up before, but Val left the mower running better than when I first bought it. Great service for the price. And you can't beat the convenience of having a fully equipped van pull up to your driveway and take care of your repairs, saving me the hassle and/or expense of transporting the mower across town. Val is all about providing a high quality of service. He took his time and did the job right. He provided the best value for service around. I will highly recommend CornerStone 777 and use them again for my lawn mower repair and other handyman stuff. Thanks Val.

Val did an excellent job getting my riding mower back up and running. He diagnosed the problem and had everything needed to fix it that day. He’s also a personable guy with fair prices. We did have to reschedule our initial appointment after he ran out of time in the day to get to our house. However, he offered a new time and then was able to come several hours early. I would highly recommend his services.

Val was great to work with. He was very communicative, and repaired my grill without issue. It was a charcoal gravity fed grill that needed an air intake replaced. Val assessed and fixed very promptly, and patiently waited while I tested to confirm it worked properly. I look forward to working with Val again on other projects.

Val came to our home to work on a large zero turn lawn mower. He was thorough, extremely proficient and knowledgeable. When faced with difficulties he was resourceful and persistent. He has a very engaging personality and fascinating life experiences! We look forward to having him return for other projects!
