Get matched with top deck pros in Union City, CA

"A job well done to correct issues with my new deck!"

"I am writing this review on behalf of Javier Flores I engaged Javier Flores to build a deck in my back yard. I could not be happier with the job he did. Javier and his brother Daniel arrived promptly at 8:00 a.m. each day and worked hard all day, with the exception of lunch. The two of them work together very well. When they finished the deck, I told them that I would sweep off the saw dust, but Javier wouldn’t let me sweep the deck, He told me I am paying him to perform that duty. Javier and Daniel are experienced hardworking men who value precision, and pay attention to the littlest of details. Our new deck is as stiff as concrete, no sags, no squeaks at all. I am so happy with the deck, that I am going to have them install the deck railing also. I would gladly recommend Javier to anyone that needs a deck. Henry & Mary Anne Price"

"They started each day at 8:00 AM and worked until 5:00 or later. They were very polite and professional. The lead person George would explain what they would be doing each day and then perform the tasks. The deck looks like it is brand new and the redwood has the original color and grain. Note: the bill included 4 hours of setting the deck screws so they could sand. Otherwise they performed to the bid."

"Super happy with our new deck from Bayside Builders Group. From the initial quote down to the final inspection, everything was handled professionally. The builders were fast, respectful of our property, and clearly knew what they were doing. The finished deck looks amazing and feels built to last. Worth every penny."

"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!"

"EXCELLENT JOB! They built me a composite deck at a very reasonable price and I'm very happy with it. Thank you!"

"My aunt was right to recommend us Bayside Builders for our deck. They turned our neglected space into something amazing. We love it. Thanks guys!"

"Pleasure to work with. Made clear of what actions and costs would be up front. Cleaned up the area daily as much as possible. Hardest group of workers ever. Project manager Ben kept in close contact throughout project. Ended up with a beautiful deck."

"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!"
