I would highly recommend atleast talking to G & O Waterproofing before you make a final decision as to who you are going to use. My first impression is they are a A+ / 5 star company and honest. Thank you Alex for your time today.

Look no further! As a homeowner I was overwhelmed with the process of finding a professional and…read moretrustworthy waterproofer as I was struggling with a leaky 600 sq ft deck that was literally a sieve into the bedrooms below. Living by the beach made us susceptible to overbidding subcontractors trying to take advantage of the unassuming and desperate homeowner. Omar came over and gave me a FAIR bid not knowing what he would find underneath my 40 year old deck. He found layer upon layer of cement and materials that needed to be demolished. The deck was on my 3rd floor and the crew had to enter my home to get to the location. They were respectful, professional, timely and communicative. They advised me on what to do both before and after their job and is still available via text or phone. If you have ANY leaks and are in need of a waterproofer - CALL OMAR at G & O. You will no longer stay up in the middle of night worrying about where your leaks are coming from because your house will be sealed! This was my first interaction with a waterproofing expert that could own that title. Leaking deck? CALL OMAR.

Professional Drainage Experts were awesome to work with! Foster was on time for our initial…read moreproperty assessment and showed us two options that worked within our budget. He walked around the property and broke down the different drainage solutions while answering our questions. He made it easy for us to understand each option. We did get quotes from other vendors but ultimately chose Professional Drainage Experts based on the customer service and willingness to work to find a solution for our property that was in budget. We were able to get a full system added to the property in 3.5 days. Julio and his team were great! They were promptly on time each morning. Cleaned up after themselves. Even hosed down the driveway, stucco, and walkways afterwards. After everything was installed, Julio walked us around the property and explained all of the elements of our new system. For what feels like a draining home project as a first time home buyer, Foster and Julio made the process feel less daunting and stressful. Highly recommend. 10/10

From the estimate process all the way through to the last touches, I am happy to say I now have a…read moredrainage company that I know and can trust! Their estimator, Foster, was alongside me throughout the job process with any questions or concerns that I had. Before the job even began, he ran through several scenarios with me and was very patient. He understood my objectives both as they related to aesthetics and my pocketbook. In the end, we came up with a plan that was viable and as aesthetically pleasing as could be managed given the situation. Once the job began, the primary person of contact shifted to Julio, one of their project managers. He was on property every day supervising and working alongside his crew. The crew was very polite, hard-working and friendly. They were very well supported by Julio. This may seem like a given, but often it is not so it did stand out to me. Once all of the work was done, Julio gave me a final walk-through, showing me how the various components function and made certain that I did not have any lingering questions. I think there were two follow up visits after the work was completed in order to accomplish this. There was no point along the way where I felt like they were taking shortcuts, using materials that were inferior quality, or anything of that nature. Their concrete cuts were incredible, and I have seen some really bad cuts in my past. And they did a beautiful job with brick work, including redesigning some curved areas of brick that needed to be removed during the job. Veronica in the office was very helpful as well. All in all, having my work done by Professional Drainage Experts was a very positive experience and I give a hearty recommendation to them!

The work is of exceptional quality, and everything was clearly communicated prior to us signing anything. I can't say enough good things about the entire experience - the quality of the work, the great communication, the reasonable pricing, and the easy, convenient scheduling. The team was friendly, professional, and knowledgeable, and they went above and beyond. We've already had a very heavy rain to test it out, and it is perfect! Highly recommend!

He obviously has a wealth of experience and was thoughtful in his approach in both identifying our problem and presenting solutions. We went rather far down the road together, but because we needed to bundle our work with various other projects, we ultimately went with another company. That said, I felt compelled to write a quick review and let people know that Eldar was quick to respond, thorough, and thoughtful in his approach with us. Will certainly reach out to him if problems present themselves in the future.

As a real estate developer and general contractor, I've worked with countless contractors and…read morevendors across Southern California. I've seen the full spectrum--the good, the bad, and everything in between--and there isn't a component of a home I haven't rebuilt or replaced multiple times across various projects. I don't give recommendations lightly. California Decking and Waterproofing was excellent to work with from start to finish. Their team was punctual, reliable, and professional, and the quality of their work speaks for itself. The deck they rebuilt is significantly better than the original construction, and the warranty provides real peace of mind. We interviewed four different companies before making a decision, and I'm confident we chose the right one. I would not hesitate to recommend California Decking and Waterproofing.

I had a roof leak during heavy rain back in February 2024 and reached out to multiple roofing…read morecompanies to get it checked out. The first roofer showed up, glanced at my house (didn't even go on the roof), and immediately said I'd need a full roof replacement--based off Google Maps. That didn't sit right with me. The second roofer came out and said they'd need to use a drone (and charge for it), and also suggested I'd probably need a new roof. Again, no real inspection. Then I contacted JNSA Roofing, and this is where things changed. Nathan's dad--the founder--came out personally. Old school, straightforward, and clearly takes pride in his work. First thing he said was basically, "How can they say that without even going up on the roof?" And then he actually got up there and inspected it properly. He identified the real issue and recommended a repair instead of a full replacement. The work included cleaning debris, pressure washing, fixing problem areas, sealing seams, and applying a silicone coating to the flat roof with proper materials and standards. They also provided a 5-year workmanship warranty. Bottom line: they did a great job and the leaks completely stopped. Later on, I noticed water near my back window and thought it might be related to the roof. I called Nathan in April 2026, and he came by to check it out. He showed me it was actually the window caulking and explained exactly what needed to be done to fix it. Both Nathan and his dad were professional, easy to work with, and clearly know what they're doing. I'd absolutely use them again for any roofing needs--hopefully not for another 15+ years.

We had an abysmal experience with Nathan and his son(s) from JNSA…read more We contracted them for simple repairs to a flat roof that had undergone soffit extensions and fascia replacements. After 4 major leaks which caused extensive damage to our wood floors in the kitchen, dining and living rooms, we contracted a new roofer. They showed us multiple problems with Nathan's work: 1) roof sheeting had not been torched down. 2) sheeting was left unattached to the subroof structure and lifted away with almost no force. 3) seams were crooked and uneven. Some had large gaps where water could seep under 4) subroof was not leveled properly leaving areas that would eventually break apart. A $12K job that cost us $20K to do over. Existing works had to be completely removed and replaced. Ruined $8K in custom aluminum fascia that we had to purchase and wait 4 weeks to be replaced, before the new contractors could start again. Over $4K needed to sand, stain and refinish our hardwood floors. We were told they used a roofing technique that was the bare minimum and would never meet basic code regulations.
