    Old rust under old patch
    max k.

    I was having a lot of water leaking after a bad storm. John was able to come out quickly and found an old patch that wasn't sealed anymore. His team sealed it quickly. It was $850, which was on the expensive side but I was glad to have it over and dealt with quickly.

    Love the balcony with new pavers and fully Waterproofed!

    John and his team did a great job on waterproofing our balcony which had been giving us headache for years. His team, including Samuel and Lupe, is hard working, responsible, and attentive to details. They did a good job on making sure the work will not damage the landscape plants below, and on cleaning up after every day's job is completed. We are very happy with every phase of the project, from removing the old tiles and concrete, replacing the damaged plywood, applying the waterproofing membrane to manufacturer's specs, conducting a 24-hour water test, and to installing the amazingly looking pavers. They also did a good job on fixing the downstair ceiling where leak was. I like the warranty they provide and their commitments to honor it. We look forward to a leak-free balcony for years to come, and I have confidence that John has delivered it. I highly recommend Bay Area Waterproofing!

We had to reach out ourselves to find out what happened. In response, they blamed one of their employees for leaving and had no idea about the project despite the whole team cc'd on every communication since the quote. Geovanny in particular demonstrated a complete lack of accountability and professionalism. He was curt and disinterested in his responses, offered no apology, and showed no consideration for the time and effort wasted on our end. When we asked for reassurance on the revised timeline and quote Geovanny simply told us that it was "not up for negotiation." It is doubtful that Q7 is interested in or values your business. With service this bad before they started work or got paid it is hard to imagine they would even pretend that you exist afterwards if an issue were to arise. EDIT: See business owner response below obfuscating rather than simply offering an apology and solution to ghosting the project without a single attempt to reach out about it. Evidence that this was not a one time accident but just business as usual

On the positive side, the crew (Antonio) was punctual, easy to work with, and efficient. The whole job took 3.5 hours. The issue came with the placement of the sump pump discharge location. I had talked to their sales lead (Bill) about having the water be discharged to the street where there is a storm drain. Instead, the sump pump "pop up" was placed 8 feet from the front of the house, way too close. Water can flow back under the house, defeating the purpose of the sump pump entirely. When I called Bill during the job to talk about our options, he dismissed our concerns and immediately pointed to the contract, implying that this was our fault because we signed the contract. In reviewing the contract, the design was completely unclear about where the sump pump would exit water. Bill continued to skirt the fact that that we had discussed pumping water to the street, and instead, he baked a different design into the contract with unclear markings. We are dissatisfied with the poor communication, but even more so, the lack of accountability from the company. If you hire this company, just a word of caution to walk through the design with them before signing and make sure you're on the same page about everything. We are going to have to bring someone else out to fix the issue. One more thing ... I was flabbergasted that when talking to Bill on the phone about the iffy sump pump discharge location, Bill was trying to upsell me on encapsulation! Read the room, dude.

There were many guys who came and different guys for each stage of the job. Their workmanship was beautiful. I also know how good they are because they came months ago to patch up the work of a 'bad' stucco guy and they turned an ugly result to something beautiful. I would highly recommend them and would definitely use again.

Morales Plastering Construction has been our smoothest experience yet! The owner, Alejandro Morales, is a joy to work with. He takes immense pride in his work, and it's evident that his team respects and enjoys working for him. He is a hands-on owner who (literally) isn't afraid to get his hands dirty to ensure the highest quality; he even personally helped complete the finishing paint work on the repaired stucco and surrounding areas. Communication with Alejandro and his team was top-notch. All workers showed up on time and cleaned the job site at the end of each day. We had multiple leaks in our windows, and Mr. Morales was able to diagnose the root cause immediately. He offered repair recommendations and a very fair quote--a much better route than replacing the windows entirely! If you have leaks associated with rain or any non-roof-related stucco or siding issues, look no further than Morales Plastering Construction!

I trusted his work and his company name was referred by a reputable contractor. Saber Roofing did an excellent job!  Ryan explained my roof-tile options and had great links to what they look like on real houses through his website.His site also provided information about the roofing process and materials. I waited for his service through winter rain & my own scheduling limitations, and it was more than worth the wait. Ryan's crew were professional, kept the site clean, repaired some rot of my 26-yr-old roof, installing new roof vents that only his company had recommended for safety & energy savings. I had asked for certain areas to be sealed well, preventing any  "creatures' " entrance that he'd agreed needed to be professionally corrected, which his crew did very thoroughly.  Ryan was available throughout the process and got back to me immediately with any questions I had. The contract added the plywood replacement  for the rotted areas, all clearly noted and within the price frame in the contract for unknown rot once the old roof was removed. The total payment was understandable & reasonable. The roof looks great, their guarantee also great. I couldn't be happier with the excellent professionalism, caring & quick communication Ryan's Saber Roofing provided.
