"Cal Preserving did a great job on our very difficult to install Ipe (Brazilian Walnut) deck. I would definitely use them again."

"Javier did a fantastic job with our deck project. We had structural issues with our deck so Javier had to come up with solutions to shore up the foundation before new Trex decking could be laid. The final result was a beautiful deck that exceeded my expectations. Javier was great to work with. He was very knowledgeable in deck construction. He is very communicative, kept me updated on progress. Javier is trustworthy and displayed honesty throughout the process. He finished on time and on budget. I will definitely use him again and would wholeheartedly refer him to others."

"Our new deck is stunning solid construction, great design, and exactly what we envisioned. The crew showed up on time and worked through some tricky layout challenges with ease. We’ve already had two BBQs out there!"

"I just wanted to take a moment to express my gratitude for the amazing work Geico Builders, did in my backyard. The pavers and design are absolutely awesome! I highly recommend them—every worker was always on time and very professional. Our project manager, Brian, went above and beyond to ensure the quality of the job was exceptional. If you're looking to enhance your outdoor space, look no further!"

"As a client of Bayside Builders Group, I have enjoyed working with them. Their crews were pleasant and organized. Installation was completed when they said it would, and the deck turned out to be beautiful! I know they are the best in the industry! You tell them what you want, and they make it happen! Great job! Don't think twice; call them today!"

"Needed my deck sealed after a year of curing. Quote was high, but I decided it was worth it. Lots of positive reviews. Had some water marks from pots on the deck. After the first brightening there were still watermarks. I sent Bruce pictures and asked that the guys coming to seal make sure the watermarks were taken care of. He told me to point out the spots and they would take care of it. When the sealers came, I pointed out the marks and asked that they make sure they were taken care of before the sealing. They told me that the water marks were the result of leaving pots on the deck...duh. Obviously this is what happened, but was why I was paying Cal Preserving to take care of it. I don't appreciate having to convince my contractors I want something done the right way. I ended up calling Bruce and explaining that I felt like this was being done in a rush, but he assured me his team was professional and that it would get done properly. Placated, I decided to trust it would be OK, despite the static. That was my first mistake. After they were done sealing they asked for the check (before it had a chance to dry and for me to inspect the work). I told Bruce I didn't feel comfortable with this (over the phone), but he reassured me that they weren't that kind of company and any mistakes or issues would be taken care of. I gave the sealers the check. Mistake number 2. The next day I inspected the work to find huge sections of the hand rail completely unsealed and with power-washer damage. Also the water marks were still there and now sealed in. I took pictures and sent them to Bruce. He came out and we discussed the issues. He was nice and told me not to worry and that his guys would take care of it. Another iteration and the handrail was fixed, but the watermarks are still there. At this point I feel like I didn't get the full value of what I paid, and the hassle I went through to get to where I am now, which is barely passable should be avoided by others so I am writing this review. I don't mind paying premium prices, but when I do, I expect premium work. And if I find something wrong with the work, I expect it to be fixed without contention. The fact is I feel like the job was rushed, and I was pressured into paying early. I am a relatively new homeowner and this whole experience has just been a lesson learned. If the watermarks were taken care of, and the rail done right the first time, and nobody gave me static, I would be rating Cal Preserving with five stars. Take warning!"
