Here are recent client comments:

His no nonsense, rational question and answer approach saved my client an incredible amount of time and money; he basically saved the deal.
Katie R., realtor, Glendale


We highly recommend Greg for his expertise, professionalism,humility and good nature. He bolted our 1922 house and added cripple walls at a very reasonable cost compared to other contractors.
Raj H., Los Angeles


Greg did a great job replacing a rotted girder beam supporting my house. He was very prompt, fair with his pricing, and gave honest information about what was needed and what was not.
Johnathan A., Altadena


Greg just completed bolting and repairing the foundation on my house and did a fantastic job. He was professional and was really great at explaining the retrofit. He is also reasonable in his prices.
