    Pavers wet look

    I would highly recommend Alcon Concrete. Alvaro was very nice person and he did a really great job in our patio. He was very responsive and very punctual in his work. We had pavers in our patio and they look awesome. Earlier we were worried about the looks but he did it very well and gave it a nice natural stone look that we wanted. Attached some pics of our patio for pavers work.

    Didn't respond to my request for a quote. Looking at there response rate of 40% that's not unusual for them.

I reached out to Geoff and as always, he was very responsive and offered to repair these items. Geoff and his team stand by their workmanship and products. They put a lot of emphasis on both, the quality of their work and customer satisfaction. It's becoming hard to find companies/business owners that care and take pride in their work. I will continue to recommend Swanson!

    After waiting a year and a half I have decided it was time to review Swanson's Landscaping. I had…read moreSwanson's Landscaping build a pad for my swim spa and hot tub. They were recommended by my swim spa dealer, Turbo Spas in Dublin. The crew was easy to work with, professional and followed my instructions to the letter. I just want to give some feedback from what I have learned since because this will help others avoid the same mistake I made. After waiting 28 days for the concrete to cure I set my 12' swim spa and 8' hot tub on the pad. 6 months later my swim spa cracked on the bottom. I am not sure about this but I believe the spa cracked because of the control lines running underneath the spa because that is where the spa shell cracked. Lessons learned is never add control lines where a swim spa will be set. This was no fault of Swanson's, It was my fault for recommending control line locations. All is well now because my swim spa was repaired and I have the spa floating on 3" of crushed rock and a spa pad. The spa pad and rock sit on top of 6" steel reinforced concrete.

    We just wrapped up a huge overhaul of our backyard with Jeff and Courtney from TriValley…read moreLandscaping and we truly could not be happier. We originally called Jeff to talk about fixing our drainage issues - our yard would flood every time it rained, and pool near the patio and foundation. Jeff was so thorough and explained where all our pain points were and how we could most effectively fix them. We decided to install French drains and pumps on both sides of the house to get water moving the right direction. Once we started digging, Jeff and his team realized we could make the drainage work without pumps by grading the yard differently - saving us tons of money! Naturally, we got excited and decided to increase the scope of work to include more landscaping, a few footpaths, small seating area, a bunch of sod for a new lawn, irrigation and a ton of new plants and trees. Jeff and Courtney checked in with us about budget throughout the whole project, making sure to send us new estimates when I got excited about adding something else to the revamp. The team onsite were great - personable, on time, respectful, and they also seemed to really enjoy working with each other, which we felt was a good sign. I absolutely adore my new outdoor space and we anticipate enjoying it with our family for many years to come. If we ever need more work done, I'm calling TriValley!

Jeff does a terrific job laying out the details and presents a professional design with pictures of what it will look like before work proceeds. I cannot recommend TriValley Landscape enough.

    We worked with Landscape Experts Inc (LEI) to revitalize our wild yard, cutting back swaths of…read moreovergrowth and transforming it with a variety of beautiful California native plants and nine fruit trees. They also carved out a lovely hillside with custom stairs, a spacious terrace, and game trails perfect for enjoying the view. LEI works with YesPlease.Garden (YPG) who managed the design process and Fresh Coat Restoration who completed the new fence. The partnerships were well integrated and it felt like working with a single team. See my Google Maps review for more on YPG. We are very happy with our project and would recommend LEI because they were professional, courteous, reliable, and provided clear and upfront pricing. Documenting decisions in writing proved helpful for keeping everyone on the same page. Any problems we had were resolved fairly, such as correcting the direction of our stairs. Aaron is a man of his word but prefers to conduct most of his business through texting. We first contacted LEI and they promptly scheduled a time to visit our property with YPG to see what was possible within the budget we set out. We completed the design with YPG and LEI scheduled a time for the project demolition. A later approximate time for planting was set, but that was dependent on the availability of the various plants we had selected. Everything scoped in the design was completed within the budget and any add-ons we later requested were priced separately and fairly.

    My wife and I are in love with our yard again, and we are very happy with the work Aaron and his…read morecrew did. After deciding to remove our pool, we hired Aaron as the installer for our new landscape project, and we are so glad we did. For months, work was moving forward almost every day, from demolition prep and grading to hardscape, planting, irrigation, lighting, fencing, pergola installation, pebble work, and the finishing touches. The quality of the work was excellent throughout. The paver patio, carport, and front entry all turned out beautifully, and the plants, irrigation, and lighting were installed with great care. We were especially impressed by the rock and pebble work, particularly the dry creek and front mow strip. The mix of stone sizes gave everything a natural, detailed, and polished look that really elevated the final result. Aaron also has a strong eye for detail. He regularly caught things that needed adjustment, even when we had not noticed them ourselves, and he stayed focused on getting everything right. While there were some issues that delayed finishing the project, Aaron took responsibility and worked with us to make them right, which we truly appreciated. In the end, what matters most is that we are thrilled with the outcome. Our yard feels beautiful, welcoming, and complete, and we look forward to years of enjoying it.

We had a few folks out to assess the problem and Steve from Foundation Repair of CA was much clearer in communicating what the issue was than any of the others. He also offered us different options, giving us a straightforward assessment of the benefits and drawbacks of the different options. In the end, we went with drainage, encapsulation, and sump pump installation. Ernesto and his team (David, Juan, and Kelvin) came out for the installation and we were so impressed with the efficiency and quality of their work. Overall we're really happy we went with these guys, and are feeling so relieved that we don't have to worry about heavy rains anymore!

    Foundation Repair of CA (FRC) is the most disreputable, dishonest company I've ever encountered. I…read morehired them because I didn't want to hire the lowest bidder for a change, and I regret it. I wouldn't sign the contract when told I'd have to do my own masonry repair until sales agent Jesse Marquez showed me FRC corporate material that indicated the brick facade would be removed with a masonry saw, in an approximate 2x2' square. That was false and deceptive advertising. This is what they did to my house. No masonry saw was used, only impact drills, which act as small jackhammers. FRC significantly damaged the entire brick facade, adjacent areas showed extensive cracking, entire areas had the brick facade knocked completely off the house, and the wall foundation was separated from the brick wall entirely. I told the work crew, headed by Luis, to stop using impact wrenches on the bricks immediately, then told them TWICE. Not only did they not stop, despite direct STOP work orders, they then took all of the bricks they'd destroyed, which legally is theft, called conveyance. Jesse Marquez explained that the bricks were so old they'd shattered. Luis returned the bricks after Jesse Marquez called, ignoring my several phone calls and texts. Jesse texted that the bricks were so old they'd shattered. Luis returned them, none were shattered, all were broken by the impact drills. Luis confirmed, texting that the bricks were "broken". They took the bricks to hide the damage. The day FRC received my Contractor's State Licensing Board complaint, FRC messaged that someone would come to assess the damage for repairs, and FRC would repair the masonry they'd destroyed. They first sent Robert Pagan, who acknowledged both that there were no masonry saw marks, and that the damage was excessive. According to FRC, Jesse stated Robert hadn't said this. It wasn't until I pointed out he'd said it while standing in front of a Ring camera did that lie die. FRC then sent Troy Knight, who acknowledged the same, and stated he was there to help, and would see that the masonry was repaired and more. I have several texts, voicemails and emails from FRC stating they will complete the job. They never did. FRC employee Mike Crites was sent to perform the repairs. He returned the following week with the wrong sized bricks in the wrong color, and proceeded to do more damage. This is the work that they did. FRC employee Mike Crites initially stated that he had retired as a mason, he later revised that statement, saying he'd only worked with pavers and concrete. The work performed was so substandard, FRC sent Jovincio, who was the only honest person in my entire dealings with FRC. Jovencio said he wasn't a mason, but had "some training". Jovencio replaced the work done by Mike Crites. This is Mike's effort, and Jovincio's replacement work. The work performed is clearly substandard and unacceptable. FRC acknowledged the workers sent lacked the skills, training and necessary certifications to perform masonry repairs. When I requested that FRC send a mason, and included photos of the work, FRC responded that they'd done me a favor; the workers sent were a courtesy. The very clause they'd ignored (and invalidated) by removing the bricks was cited. That they would do no more, leaving me with the bill for their damage. This is what they left. I obtained a second quote to repair the deficient masonry 'work' FRC workers had done - without a REQUIRED permit, with no mortar pins, odd-sized and broken bricks mortared in randomly, mortar lines that range from non-existent to more than an inch. Crites' also removed the brick facade foundation in several sections, replacing it with sloppy concrete. This is a code-violating 'repair' that is neither plumb nor square. The legitimate mason company from whom I obtained a repair quote updated the quote, which has nearly doubled BECAUSE of the 'repairs' performed by the unqualified FRC employees. FRC called this doing me a favor, saying the inept crew was sent as a 'courtesy'. This is not doing me a favor, this is not a courtesy, this is at best fraud. After signing the contract (under false pretenses), Jesse insisted I needed an additional pier ($3,155) because piers can no longer be placed under a window. A pier was placed under the window. Two other piers were not placed according to the county approved structural engineering ($1,850) diagram. Half the piers were installed in the wrong places, apparently according to Luis' whims. Yesterday Groundworks gave an estimate on properly placing those piers. That's how I learned that the improperly placed piers had lifted a joist completely off its foundation supports. This, too, will require additional expense to correct, before it damages my house - literally to the roof. I should have stuck with Groundworks. This is your cautionary tale - no one who values integrity, ESPECIALLY senior women, shouldn't hire FRC.
