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 did an excellent job in replacing the belt to my treadmill. He was very knowledgeable and worked diligently until the job was done. His efforts were greatly appreciated and most welcome. I would highly recommend him for any handyman job you might have on your list.

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.

I contacted them with an odd job, received a message right away, sent some images, received an accurate estimate and they came to my place that same week. They worked non-stop all day and managed to finish a 2-day job in one. They paid attention to detail, called out a rotten wood problem I had not expected and solved the issue at the same time. Will call again and recommend.
