    I first met Fred about 20 years ago. Fred has now bolted 3 houses for us through the years. A+. Use him with confidence.

He found things that other inspectors missed and he did not oversell like other contractors did. I immediately feel he is a contractor that I can trust. He explained what my foundation condition is and the detailed steps he would take to bolt and brace it to make it earthquake safe. he even worked with my budget so that I'm able to go forward with this project. Believe me, there were some outrageous quotes out there. Big thank you to Juan for amazing customer service. I highly recommend him.

That was an unacceptable waste of my time. On top of what I was already paying for the plans, I was hit with additional fees that I was not expecting. Then I was quoted $440,000 for a 400-square-foot addition, which was completely unreasonable in my opinion. The entire process was frustrating, expensive, and unnecessarily drawn out. I had to keep messaging them and emailing them to see where we were at in the process. I feel like my time and money were completely wasted. Do your research, get multiple quotes, and be very careful before giving this company your money. I would not recommend them based on my experience.

    Julian Construction's team replaced two foundation walls that formed a corner. My problem was the…read moreold corner had cracked from top to bottom in two places, one on each of the adjacent walls, and the detached corner was beginning to sink, causing the house to slide to one side. The lack of a long tube from the gutter downspout leading away from the house was a likely culprit. How did I know? The doors around that corner were not closing. I like treating issues as they arise and I knew this problem could stand no delay. I asked for estimates from a handful of foundation companies that other homeowner friends had recommended. Julian's was the only one that had a well-documented inspection, a thorough scope of work, a fair price, and reasonable contract terms. Mayo was on top of it. She scheduled me within a week after I submitted the signed contract and deposit. The crew showed up at 7AM and the foreman spent an hour talking with me while he guided his team into action.They had to jack up the house. The foreman and I stood in the room being elevated and I could hear the creaking wood and straining nails like an old man stretching his joints to his limit (my house is 115 years old). It was scary but I felt like I was in good hands. The foreman was observing every reaction of the house and giving immediate instructions to his team. He also gave me an education on foundations and how houses slide, pointing out the the accelerating slant of the vertical wood pieces in my cripple wall. I do some much home repair myself so I ate up this education! The team worked fast. I was onsite the first and last day. On the first, they asked me a lot of questions about how much leveling I wanted (I opted to keep a slight slant or else my old doors would be jammed) and I could show them all the resources (power, water, fusebox) to help them do their job. They were really nice and had a good sense of humor even though the work was heavy and hard and the summer temps were nearing 100. Mayo had asked me to clear the space (remove plants, remove gutters, remove siding if I wanted to reuse them, protect the AC unit, so I did before they came. On the last day, I was dazzled by the new foundation walls. The floor in the house even felt better to walk on, much more solid. Julian's team offered to put the gutter and the siding back for me, making a vent hole to match the old one. This saved me so much time. Their work passed inspections. The entire process was very smooth. The crew was orderly and handled all items with care. We spoke in English and in Spanish and it was fine. I'm a native Californian so knowing some Spanish comes with the culture here. Up until this experience, I was nervous about foundation replacement but working with Julian Construction made me feel it is a manageable process, even a pleasant one. When I need further work on my foundation, I know who to call and I won't be stressed out about it anymore!

    Mark and Matt have visited my home for inspection twice now over the last few years. The…read moreprofessionalism and pride of ownership was clear from the moment they arrived, fashionably early I may add (being on time, an understandable challenge amongst LA contractors). We live in a 70 yr house on a hillside with amazing mountain views; but often besieged by the paranoia of being on a hill. Mark allayed fears both times, answered questions to explain the subtle phenomenon that concerned me every so often, & confirmed everything was normal. Inspections were thorough & no unnecessary work suggested. Often, homeowners aren't knowledgeable about civil and construction work. Speaking to these gentlemen is like speaking to professors who'll tell you clearly if you don't need work; and what you may need 15 years from now. We ended up being advised that nothing was needed to be done. The most remarkable example of integrity.

Adam visited my property and spent almost an hour mapping out the entire floorplan and created a detailed plan of attack - all free of charge!!! He carefully measured whether the floor was uneven using a laser, took numerous photos of the areas of concern in the crawl space (wearing a full hazmat suit, goggles, and a high-end face mask), and patiently answered all of my questions. I had another vendor visit the property, and he only spent 3 minutes poking his head around - he did not even enter the crawl space! Therefore, it was an easy choice to go with Sunshine. I felt comfortable enough with Adam to ask him to visit my parents' home for a possible retrofit. Unfortunately, this structure does not have a crawl space / cripple walls and thus is not able to be retrofitted. I feel very comfortable in recommending Adam for other projects, and I look forward to engaging with Sunshine again soon. Thank you, Adam!!
