Sealed roof
Markisha G.

Thanks so much to John and his team! After months of dealing with unreliable contractors I reached out to John via Yelp, received a response in less than an hour, same day quote and repair. They were fast and we are still leak free.

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!

Miguel's Home Services

I hired Miguel to paint a small alcove in my San Francisco apartment (about 7 x 5 ft). After an…read moreinitial site visit and quote ($900), communication became very difficult--texts went unanswered and he even canceled once because he mixed up the job date. I had changed the color from white to a blue-green and texted him the exact flat and satin finishes. He confirmed twice that he had the correct paint, but on the day of service arrived with white instead. He then went to buy the right color, and his son and another worker did the painting. Unfortunately, the first job was poor: uneven coverage on each wall, holes and trim hooks left unpatched, light ceiling coverage, messy edges, and paint spots on the floor. They also didn't leave the paint cans behind. Miguel wasn't present, even at the end to look it all over. When I contacted him a few days later, he agreed to fix it and returned a week later with the crew. They repainted the whole alcove, and the result the second time was satisfactory. While I appreciate that he came back and corrected the work, the overall experience--miscommunication, bringing the wrong paint, poor initial workmanship, and the delay it caused--means I wouldn't hire this company again.

Miguel provides a high quality service and was quickly available for installing a large French…read moredrain, channel drain and sump pump setup. His team was courteous and effective, they used quality materials, state of the art procedures, and communication was great. He was flexible incorporating our change requests, provided a competitive estimate and stayed within the estimated costs (plus my added voluntary changes) and time frame. Highly recommend for your drainage needs! Update: a day after the work was finished, we had an atmospheric river. Unfortunately, it caused water entry in two of our rooms, which did not have water issues before. For part of the drain trench, the team overlooked that the foundation switched from crawl space to slab foundation and did not dig deep enough, backing the water right into two of our finished spaces. I reported the problem immediately and the team worked quickly to mitigate the issue by reworking the affected area under their warranty. I had to give feedback during the repairs to the team onsite that the foundation foil and protection was properly applied to the deeper level, instead of just lowering the trench on the bare concrete.

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

Over the past five years, we have completed a number of home remodeling projects, from kitchen and…read morebathroom renovations to HVAC replacement. 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!

Unfortunately, when the window had to be reinstalled, the window company used a different contractor who didn't do a good job. Thankfully, Morales Construction was eventually brought back to repair the damage--and once again, the results were gorgeous. They completed everything in just one day, and the quality of their work really shows. They're professional, efficient, and a pleasure to work with. I highly recommend Morales Construction.

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.

Among the details, the rain chain is made of copper while the gutter is made of aluminum. Having these two metals come in contact could compromise the aluminum over time. So, Saber installed the copper rain chain with a protective barrier. 3) Their client service and sales director, Jake, was super helpful and extremely responsive to all my questions. 4) The crew was very efficient, provided high quality workmanship, and left the site spotless. 5) The gutter guards that were installed provide a really fine barrier to prevent even small debris from entering my gutters, but are easy to rinse so that fine particles can be washed through the gutters. 6) The two downspouts that were installed were matched to the color of our trim. Other companies offer limited colors or simply white downspouts, but Saber offers a wide variety. 7) Their pricing is very competitive. From end to end, this was a great experience and I highly recommend Saber Roofing.
