    My yard was left in this state for nearly 7 months. l
    Tyson Q.

    The Worst Business Owner I've Ever Worked With First, I want to mention that I am also a business owner with 15 years of experience, so I understand the challenges of running a business. That said, Markus at Liaison is the worst business owner I've ever had the misfortune of working with. I first contacted Liaison in September 2021 and received a top-end quote of $99,646. I signed the contract expecting work to begin within a month. However, seemingly because Markus took on every project he could get, my project was delayed until February 2022. Then, when work was supposed to start, they said they forgot to get the permit, pushing the project back again to March 2022 - a full 6 months after I signed the contract. The project finally ended, unfinished, in October 2022 - an astonishing 7 months after it began. During this entire time, my yard was torn up with a portable toilet in the front. There was no sense of urgency or efficient project management. I wish the delayed start was the end of my issues with Markus and Liaison, but it was just the beginning of the worst contracting experience of my life. Once the project finally started, I was informed that Sean, the project manager I originally met with, had quit. I was left without a project manager for weeks while the subcontractors tried to figure things out on their own. I had only met Markus in person for 10-15 minutes when he came to tell me Sean left. The project began with demolition and trenching. The trenching bill came in at exactly the high end of the original quote, even though it was supposed to be based on hours worked. It became clear that hours weren't being tracked in detail and Markus planned to simply bill the maximum for each line item. The original quote only included a line for "Retrofit existing - Time and material at $85 pr. hr." Yet I was billed $7,200 for trenching alone, not even the irrigation retrofit. No change order was ever made for this major scope increase. Next was the hot tub pad and decking, which ended up costing nearly $50,000. Issues included: - The deck was finished before the gas line was hooked up, requiring boards to be pulled up - The deck finish needed to be redone by a third party - The removable stairs to access the hot tub panel were misaligned and wobbly Furthermore, despite repeatedly communicating our desire for a clover lawn, Markus' crew showed up one day and added gravel, compacting it down because they thought we wanted grass turf. This not only added cost but required completely tearing up the yard later because they didn't fully remove the gravel, leaving the soil too compact for growth. When it came time for planting, the crew brought about 20% of the wrong plants. After I rearranged many of them into the correct layout, we later discovered that some still weren't the ones we originally selected. Many aspects of the project were changed without any negotiation. When I brought this up, I was told that I had made the changes myself, without any evidence or even an in-person conversation. This is the result of a detached business owner who has taken on too many contracts, a lack of project management, poor business organization, and/or blatant dishonesty. After more than a year, $125,000 paid, going through two project managers who did next to nothing, a budget overrun of nearly 30%, much of the original plan scrapped, and having to redo a lot of the work ourselves, I was done with this disorganized company. The only positive was working with Ernie, the electrical/gas subcontractor, who demonstrated integrity, communication, respect, and quality work. I strongly encourage anyone considering a project larger than simple decking or fencing to find a different contractor. Even for those, I'd advise finding someone more organized and honest to work with than Liaison. The experience was so bad, I am likely considering a lawsuit against Markus and Liaison.

    I recently had to find a contractor to repair the sidewalk in front of my house due to inspection requirements from my home insurance company. I was given strict parameters and a timeline for the repair. Markus and Chrissy from Liaison Landscapes were extremely timely, thorough and super professional to work with from bidding to work completion. They even looked at the weather in advance and given rain forecasted, planned and completed the job in half the time originally allotted. Phone and email readiness and follow-up was good all along plus the work team itself was friendly and efficient. Nothing but 5 stars here. Highly recommend Liaison Landscapes!

    WOW is all I can say. I was so impressed with Sean and Octavio on this massive undertaking. I shopped around for quite some time and hadn't been able to find a company that was able to handle all the various complexities of hardscape, drainage, wood construction and planting that I was looking for in this backyard remodel until Liaison. They were so professional and Sean was extremely patient working around my 100+ revisions as the project evolved. He stayed on time and in budget which I have found to be a huge rarity. As you can see in the before pictures, our yard needed A LOT of work to reconstruct the retaining wall, flatten land next to the garage to add another parking strip, add a platform for the hot tub, add drainage and repair broken pipes throughout, add automatic irrigation, build custom wooden benches and under deck lattice. This project was a monster and Sean and Octavio handled it with grace. I really appreciated how they came up with solves along the way when we hit roadblocks (built-in bench was there idea) and created useable spaces at every corner of the complicated hillside property. They worked tirelessly 8-4, 6 days a week for months. Was such an incredible value for the amount of work this was. Would highly recommend!! Can't wait for all the plants to grow in so it will turn into the privacy garden of my dreams, thanks guys! - Krista

    Markus and team did an awesome job on our backyard. We gave them a rough idea of what we wanted and they came up with a great design that fit our budget. They got the work done quickly and were very professional. Every guy on the team took a lot of pride in their work and made sure it was done correctly. They worked with our last minute adjustments and made sure the final result was something we were happy with. We used to avoid going in our backyard because of the mess that it was but now we love it!

    We couldn't be happier with our backyard work. From a barren very steep incline to a beautiful garden with various fruit trees and small shrubs that lead you down to the platform at the bottom where the kiddos can play in their new play yard and the adults get their own little corner to lounge as well. All extremely well light as well as irrigation and drainage lines setup so that everything can be the done the right way. Making small tweaks and changes along the way to suit our taste we had no issues getting things to look the way we wanted. The workmanship is top notch and always looking to make things more useful like moving our irrigation valves from the side of the house to the back so they could all stay together and out of the way. To coming up with the idea of using the ropes as a bannister to give things a fun and unique look. See for yourself in the pictures I've attached at how great things look in the day and night.

    Markus and his team at Liaison did a stellar job transforming our SF jungle of a backyard into a beautiful and functional space. Markus was extremely professional and straightforward from the initial consult all the way to the closeout walk thru. We came to them with a general concept of our vision, and he helped us finalize and execute the plan within our budget, ahead of schedule, and with no surprises along the way. A contractor myself, I cannot speak highly enough of the quality, value, professionalism, and ease of execution we experienced with Liaison. I wish more contractors of this caliber existed to service Bay Area homeowners!

    New Concrete, Turf, and Planting
    Patty A.

    Liaison Landscapes did an incredible job with the complete re-design and construction of both our front and rear yard. As an interior designer myself, I have been through many projects and worked with a ton of contractors, and I have to say that the entire team at Liaison was an absolute pleasure to work with. We began the process with Elliot, their (all-star) designer and he created a beautiful plan which we felt represented all of our 'must haves' and even our 'nice to haves'. He was incredibly helpful in nailing down details like materials selections, finishes, plant palette, landscape lighting, and even finding and artificial turf that looks so real! We then worked with Octavio, one of their crew leaders who implemented the design with excellent craftsmanship, great communication, and no delays in the schedule. The crew was always punctual, courteous, and most importantly left our property tidy and presentable each day after they left. I would highly recommend the team at Liaison Landscapes for both their design expertise and their ability to make a plan come to life. We are extremely happy with the finished product.

    We had a great experience working with Sean, his site manager Luis, and the entire crew at Liaison. As one other reviewer mentioned, I too was wondering who Sean was after all of the initial reviews mentioned Markus, but Sean is great. He came out a few months ago (pre-COVID) to talk through some general concepts that my wife and I were looking to do with our yard, as well as suggest various options to work with our budget. After inundating Sean with questions via email, we paid a deposit to get a full CAD drawing done as our project was hardscape and not just plants. Sean was then open to our suggestions and revisions on said drawing and answered, again, more questions than I'd want to answer myself. (Thanks, Sean!) Work began right after the COVID restrictions for outdoor companies lifted in early May. There were various parts of the Liaison crew specializing in different areas. We had a fantastic team that built our fence and a custom box for our utility meter (Thanks, Rene!) as well as others handling stones, debris removal, planting, irrigation, etc. Everything was done on time, and any concerns I had throughout were addressed by Sean or Luis on an ongoing basis. They also have 90 day guarantees post install for plants and offer an optional maintenance service going forward. A few of our neighbors have complemented the work done, and we've been happy to refer them over to Sean for their own projects the last few weeks. This is a great team, highly recommended.

    After: New outdoor kitchen and concrete work
    Shali N.

    Markus and his team did an awesome job on redoing our entire yard. Their concrete work is top notch, and they were even able to do a very specific finish that I was looking for! His team also did beautiful work with our custom wood and steel pergola. We are so pleased with the results!

    New everything, including the little outdoor office.

    Writing this review as I sit on my beautiful deck in my amazing backyard which was recently completely redone by Liaison. Markus and his crew (Elvis) were great to work with and we couldn't be happier. Our project was pretty intensive - we had the typical small SF city lot: sloping as we are on a hill, concrete, old fences and failing retaining walls. We wanted to make it usable, low maintenance, utilizing every inch of the space and of course, nice to look at. Not without its challenges, but with each new "curveball" thrown at us during the project, we were able to work with Markus and Elvis to come up with a solution that met our needs and didn't slow the project down. Besides having a great working relationship, the quality of work is top notch. We've had a ton of compliments and are definitely the envy of all our neighbors. Even after the project has finished, Markus has been available for follow up questions or minor adjustments we wanted to make. Doing big backyard projects like this in SF is always challenging (old homes, various city stuff, neighbors, cost), but Liaison was a great choice and we can't recommend them highly enough.

    These guys were fantastic! Spoke to the owner Markus who was very knowledgeable and easy to work with. We were not exactly sure what we wanted, but he took his time to give my wife and I plenty of ideas to think about. We went ahead and booked Liaison Landscapes and their team did an amazing job. Our backyard was a major source of stress but now it is a relaxing and tranquil place to spend time. We updated the walkway as well, and it gave our house a whole new look. Really happy with everything these guys did, and I would absolutely recommend them. Just overall a really great experience.

This involved shoring the house, pouring all new foundation and retaining walls, and expanding the walls and framing. Overall, Mick (owner) and his team's work was thorough and detailed, and I would recommend him to other home owners, and consider him for my next project. 1) Mick (the owner) was the most thorough in bidding compared to other contractors. He came to the house multiple times, brought subcontractors to look at the job, and ultimately gave an estimate that was competitive and had my confidence. 2) Mick was one of the safest and most punctual contractors I have met. The work would start at the exact time every day, the work site would be thoroughly cleaned each day, and there would be high emphasis on safety (hard hats, signage, etc) 3) Mick had to communicate with an architect, three engineers, and a variety of subcontractors and he handled that very well. He was always a step ahead in seeing upcoming problems to resolve. 4) Mick was at the job site and worked with others himself each day! This raised the quality and made sure the work stayed on track. 5) the work finished on time, as previously estimated, despite the fact that the work was done during the rainy winter. 6) Most importantly, the end result was great, all inspections passed on the first try, and other contractors and subcontractors that visited the site were impressed.

During the free consult Alejandro was clearly much more engaged in actually solving my problems. Example: the fence needed to be low enough to see over as I back out of my driveway, for safety reasons. Alejandro held a tape measure at various heights and various points as I backed out. It seemed obvious to him that this was the right thing to do, but no other contractor I met with did this. 3. Construction was done in a single day (7 hours). 4. Sometimes I work with contracting firms where an attentive sales person asks about your project, and then a separate team (plus an annoying game of telephone) comes to actually work on the project. Not with Maldonado! At least for now Alejandro is not only figuring out the design with you but actually building the fence 5. Alejandro made several AI renderings showing the different options, which were quite helpful. I'm surprised more people aren't doing this 6.

    Jim and his crew did a phenomenal job on our foundation replacement project. From the first time I…read morereached out to him, he was very patient and forthcoming with me, even offering advice and guidance with how best to get started with approaching the city, as well as assessing bids. We have a three-story Victorian that needed the original brick foundation replaced, as the condition was very deteriorated and well past its useful life. Jim came out to assess the situation and wasn't intimidated at all. He is a straight shooter and tells it as it is, and our job was going to be a major one. I picked Jim because he truly knows his craft and enjoys what he does. Plus he doesn't sugarcoat the inevitable surprises that will arise (plus he has a wicked sense of humor and some great stories to share). We started in the middle of last Summer and finished right on schedule during early Fall. I will be the first to say that it was a huge capital investment to undertake: excavating, removing the original perimeter foundation and shoring up the massive structure, while ultimately putting rebar and pouring the new concrete. I was quite nervous about all of the things that could have gone wrong, but Jim communicated constantly throughout the process and made sure his men were on task and doing quality work. Mid-way through, we had a incident where the sprinklers were inadvertantly triggered overnight, causing water to flood into the trenches. Jim came out immediately with his men after they became aware of the situation (even though it happened on the Labor Day holiday) and personally went to work to shore up the beams that were supporting the house and checking and double-checking any structural weakness caused by the water. Because of his diligence and attentiveness, I honestly felt like we averted a major catastrophe. Jim treated our home with the care and attention he would have given had it been his own home. He has a penchant for finding creative solutions to deal with a host of unexpected problems, and through it all, he was punctual, steadfast and very thorough with his oversight, being on-site every day. We have now moved on to our next phase of the project, but without Jim Patterson & Co, we literally wouldn't have a solid foundation for which to proceed. My thanks to him and his team for the transformative work they did to our forever home.

Last summer Jim and his crew replaced our 130 yr old brick foundation. It was a huge job and we shopped it around, but Jim's estimate came in at the bottom end of the range. What really won us over, however, Jim's approach. He is old school and dedicated to the craft - you could just tell by the way he approached the bid and the conversations w/ the Engineer. And he did not disappoint. He showed up early every morning, had his crew in line and busy every moment of the working day. His guys respected him and all mentioned how much they learned working w/ Jim. I was pretty hands-on, crawling around and checking things. Jim helped me understand all of the parts of the process and how he was making key decisions. He was patient w/ my questions and often went the extra mile to keep me happy. For example, I needed to replace some drainage and he had his guys dig up the concrete on the side of the house to help me out (definitely NOT in the contract). There are also little personal touches that you can't pay for. When his crew found an antique bottle from the SF Dairy Company, Jim put it by the front door with a little note - he knew that this kind of thing would matter to us. Anyway, the job was done on budget and ahead of schedule with great communication throughout. Most importantly, Jim always worked with us to resolve any issues (real or perceived) that I came to him with over the course of the project. Five stars!!
