CUSTOMER TESTIMONIALS

This is one of Justin O’Brien’s very happy clients attempting to tell those who would want to know just how comfortable they would be doing business with this young man. He has installed wood floors in four rooms of my house, built an atrium fence and constructed raised vegetable bed which are pure delight for an octogenarian who does not think it is time to give up serious gardening. In addition to all of these obvious talents, Justin has a crew of talented young men who are not only good at what they do but love dogs and Cajun cooking and are intellectual conversationalists.
I could go on ad infinitum about how happy I have been with Justin and his helpers and I would be happy to
talk to anyone considering him as a builder. Since I can be very particular about work on my house, I would
expect my recommendations to be seriously worthy of consideration by anyone looking at perfection, or as
close as you can come.

O’Brien Building did do the job right! I love my new front deck. I make time every day to enjoy the luxurious wood and the sound construction. Having the crew on site was pleasant and positive, Santa Cruz county natives making a living and living it right. The job itself was not as straightforward as it sounds. Because it was a rebuild with some tension around the responsibilities for the initial errors in construction by a different contractor, finding someone to take the job was difficult. Michael Hartrich, guild founder, was my go to and helped pair me with Justin O Brien. Without their help I am afraid I would still have the buckled warped hazardous deck rather than the welcoming luxurious deck I now enjoy. Justin’s confidence and Micahels good will were responsable for this wonderful transformation. There are so many builders in Santa Cruz but to find a builder , and who is a member of a guild, that can promise and deliver, is a privilege. Highest regards for this team and its support, and big big thanks for an expert job.
