Nothing but headaches after hiring them. I wish I could give less than one star here. Mr. Jack Toki and Cornerstone Construction are nothing you would want in a contractor. They did not show up when they said they would, did mediocre work at best, caused damage, and failed to complete the job within the price they quoted. Not only that, but also they do not have insurance so anyone on the crew who gets injured could have sued us, the homeowners! Strongly recommend not to hire Cornerstone Construction or Jack Toki, or any of his crew (they may try to do some side business).
A nightmare. Hiring Cornerstone Construction and Jack Toki has cost us many sleepless nights and about twice as much money as we bargained for. Over three months of anguish for a three-week project. We hired this company to relandscape our back yard. They showed us a nice portfolio and did pretty drawings of our yard before we hired them. They asked for money up front and continued to ask for money until we realized we were on the verge for paying for the entire project. Then they disappeared leaving our back and front yards torn up, parts of our house damaged from being smashed by equipment, part of the yard used as a toilet, and piles of debris and waste everywhere. We ultimately paid them more than the contract price and are left with having to hire another company to fix the damage and finish the project. We did everything we could to work with them, but they took advantage of us. They are tricky because they are actually quite skilled and may start a project well before they claim to run out of money and either get you to pay more than they are due or abandon the job. Beware beware BEWARE!!!
"Jack Toki did the side patio and back patio of our home in flagstone and brick. It is a job to be proud of. Many neighbors have stopped by just to admire it. We recommend Jack Toki without reservation."

"This is to recommend the brick work Jack Toki completed at our home. My ideas were vague. Jack managed to understand them and the finished product is grand. He has an artist's eye and is a diligent worker." 2/27/03

"Jack Toki and his crew have done an outstanding job on our new patio floor and were very responsive to our requests. I highly recommend him for this kind of work." 6/5/04
Jack Toki "ran out of money" The balcony job was supposed to be $15k It right away went to $20k. Being an understanding person if did pay him in increments and paid him up to $15k and the job is only 50% done. I have documented attempts of calling and leaving messages of over 30 times. He has promised he will be back and finish, the weather is great and still no Jack or Cornerstone Construction. There is unfinished concrete work, patio, landscaping with horrible drainage and dangerous for my kids to go out to play. He started this job in December of 05 it is now 4/30/06 and no Jack.
