    Our new roof!
    Grace T.

    Ves and Nathan were excellent to work with. They gave us a very reasonable estimate and came highly recommended by a friend. They were punctual and very professional. The whole team was efficient. They were quick to answer our questions. They finished just as scheduled. We are satisfied with their service and couldn't be happier with our new roof!

    Perimeter is not water tight. Flashing does not extend to cover roof edge & substrates are exposed and will be ruined by moisture

    I bought a house that recently had work done by this roofing contractor and it was not done correctly. As you can see in the photos, the perimeter edges are completely exposed with large gaps that will allow moisture and water intrusion into the roofing system and probably ruin the foam and plywood sheathing layers, jeapordizing the waterproofing integrity of the assembly. I tried reaching out to the contractor to ask them to repair the work under their workmanship warranty, but they have been ghosting me and failed to respond. After multiple texts, phone calls and emails, I have up. If I could give 0 stars I would. DONT EVER use this roofing contractor.

    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!

He responded immediately, was very friendly and thorough, and was super upfront in his assessment and options to fix our drainage problem in our front entryway. We had a huge problem in the previous design of our that caused the inside of the house to flood during any heavy rain. 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!

Eldar was easy to work with and he kept to his original estimate even though our job turned out to be a little more complicated than he anticipated. We also had a few small issues with his workers but Eldar took responsibility for everything and made sure everything was addressed. In terms of his work- he actually ended up installing 2 french drains instead of one and I'm looking forward to the first fall rain to see how it does.

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.

What stood out most was their professionalism and honesty--they never tried to upcharge or renegotiate the price at any point. I also had tenants on the property during the work and received zero complaints, which says a lot about how respectfully and professionally they operated. Technically, it hasn't rained yet, so I can't fully speak to the long-term performance--but from what I've seen so far, the work looks solid and well done. On top of that, they offer a strong warranty, which gives extra peace of mind. If you need waterproofing done, don't overthink it--just go with Victor.

But this is a rental property. There are elderly people in the home as well as people who work from home. The person texting me was apologetic. My biggest concern on communication were when fees increased or new fees needed to be paid. PFR had to order additional material which was not expected or disclosed it might be needed in the original contract. I noticed when they sent me the bill. Had I not looked over my bill in detail I would not have known about the additional cost. I spoke to the owner who apologized and gave me a discount. My last bill had an additional fee for a special inspection. Again I was not notified about this additional fee. While this special inspection possibility was disclosed no one told me it had happened. Therefore I had to scramble to get the extra $825 to pay PFR. I should have known about this charge the moment it happened so I could plan accordingly. Those were the main hiccups. Other than that the process was great. It took awhile because of unforseen material that needed to be ordered. The whole process took about 7 months. Which I suspected it would because we were dealing with LA County for permits. The work they did looks great! I am very happy with their work. Everyone was very helpful and nice when I spoke to them, apologetic for the mishaps. The tenants say all the workers were nice and respectful.
