They do beautiful work. We’ve worked with them to do two projects that both included pool, spa, hardscape and landscape. I highly recommend them. **★★★★★ — Lacey L., April 2017** > John DeMaria, with DeMaria Landtech, Inc. of San Diego, is an outstanding contractor to work with and I highly recommend his services. He currently is completing a major remodel on our back yard including landscaping, hardscape, large spa and fire pit. Our yard was a challenge to say the least. We live on a steep incline and all work had to be done by hand. The workmanship of him and his team is fabulous and John was wonderful to work with every step of the way. Highly recommend him. He is creative, skilled and is extremely attentive to getting the details right! **★★★★★ — Karin C., March 2017** > Exceptional service and quality of work. John and his entire team were a pleasure to work with. They stayed on schedule and within budget. Great communication. We love our new backyard and highly recommend DeMaria Landtech. **★★★★★ — MimiValentin, Jan. 2017** > These photos don't do this project justice. These were just quick snaps. I could only upload 4 per the website. > > Anyhow, DeMaria is the best you will find in San Diego. He can seriously make anything you envision become reality. His experience and service is extraordinary! I can't say one bad thing. His team of guys from start to finish were amazing and the craftsmanship of his team is indescribable. > I have built custom homes, restaurants, you name it and this by far was the quickest and easiest team to deal with. He kept his word and always did what he would say... on time. You definitely get what you pay for... > I am so pleased with his services we have decided to take on more projects with DeMaria. > If you are looking for a one stop shop you got it. They can make anything happen. > Thank you for everything!! > On this project I rebuilt, renovated and created. > We built two heavy beam arbors, outside BBQ island, infinity parameter spa with Baja edge and shallow to deep end pool, 2 koi ponds with under stairway passage, lower botchy ball court, fire pit lounge area and entertainment area. Little bit of everything. > I will try to post more pictures if the website permits. Please view my page for more updates. Thank you **★★★★★ — 4casons, Jan. 2016** > DeMaria was excellent. Gary designed an incredible back yard encompassing everything on our "want" list and Johnny and his crew built it quickly and efficiently. They did a great job! We also installed the new OmniLogic Pool control system with the new HydroRite UVO3 system by Hayward Pool Products. The water looks amazing. We could not be happier! DeMaria outperformed our expectations. Thank you De Maria for a beautiful backyard! **★★★★★ — savitt, Nov. 2015** > We hired DeMaria Landtech after we were referred by friends who raved about their experience with John's company. In fact, John won top honors for the design and construction of their truly magnificent back yard. We worked with three companies during the bidding process and felt that DeMaria Landtech was the best fit for us as he shared our vision and passion for the project. Once we contracted with DeMaria Landtech, John delivered a team of professional highly skilled and detail oriented workers. The results were outstanding winning John the top honor for Achievement in the Large Estate remodel division. Following the job he demonstrated the highest customer service level you could ask for. He is a true professional, who cares about people and delivers on his promises. I highly recommend John for any landscape project. **★★★★★ — Sheri V, May 2015** > After purchasing a new-construction home on a large unfinished lot, we interviewed six contractors, regarding potential landscaping options and pool/spa installation. We selected the DeMaria Landtech team, based on design, price, and range of service, and were exceptionally pleased with all aspects of the experience, including the following: > > 1.Outstanding communication — John DeMaria personally answered each of our questions and was incredibly efficient in replying to texts, e-mails, and calls, on a real-time basis. He stayed in regular communication with us at every step and continually advised us about the project's upcoming phases. > 2.Comprehensive depth — Landtech has its own designer/horticulturist, which streamlines the planning phase. Also, because the company has its own pool-plastering division, John does not have to coordinate with a separate pool subcontractor. Pool and spa installation can have a significant impact on the schedule (due to the time required for digging, applying shotcrete, placing tiles and coping, and plastering the surface), so it is extremely helpful that these steps are synchronized in-house. > 3.Consistent professionalism — John offers a friendly, hassle-free approach. He presented various material options in an easygoing, matter-of-fact manner, always within the financial scope of the contract (no debates or hidden costs), and the design was executed to our complete satisfaction, right down to the final punch list. > 4.Strong reputation and emphasis on reliability — There is a reason Landtech is rated A+ by the Better Business Bureau; namely, the team is motivated, diligent, talented, and reliable. Despite at least a week of rain delays, the crew stayed on task and completed our project in a timely fashion, maintaining a courteous, helpful attitude throughout. John places considerable trust in his team and treats them with respect, and they return the favor. > 5.Consideration and competence — When we interviewed contractors, certain horticultural and architectural bids we received seemed more aligned with the planners' preferences than ours. The DeMaria team, on the other hand, incorporates a client-first perspective in every element of the work. John's designer/horticulturist, Gary, kept our preferences the primary focus of the project, taking scale into account and skillfully combining our requests with his knowledge (of soil type, sun exposure, and planting zones), to provide a thoughtful, aesthetically pleasing, low-maintenance design that optimized our initial input. > 6.Robust quality — John's aim is to offer a competitive price based on production of the highest caliber. He utilizes dependable Caterpillar equipment, superior building materials, and expert engineering/construction methods, with long-term durability in mind. > 7.Extensive follow-through — The Landtech team ensures that all aspects of the project are completed with thoroughness and attention to total client satisfaction, start to finish. > > We are greatly appreciative of DeMaria Landtech's efforts on our project and the excellent on-time, on-budget results — we highly recommend the company! **★★★★★ — Southwest Boulder & Stone, Oct. 2014** > DeMaria Landtech Inc is one of the top landscape contractors in San Diego. SWB and DeMaria Landtech have worked together for a number of years and we have always seen him do great work. Spend the time to look through his pictures; you will be blown away! ## Selected projects - [Wolfe estate](https://www.houzz.com/hznb/projects/wolfe-estate-pj-vj~147278) - Location: Not specified - Photos: 6 - [Casa De Encinitas](https://www.houzz.com/hznb/projects/casa-de-encinitas-pj-vj~872682) - Location: Not specified - Photos: 11 - [Las Villas](https://www.houzz.com/hznb/projects/las-villas-pj-vj~142708) - Location: Not specified - Photos: 27 - [Applegate](https://www.houzz.com/hznb/projects/applegate-pj-vj~758547) - Location: Not specified - Photos: 9 - [Casa de Fairbanks](https://www.houzz.com/hznb/projects/casa-de-fairbanks-pj-vj~142764) - Location: Not specified - Photos: 9 - [Wild Flower](https://www.houzz.com/hznb/projects/wild-flower-pj-vj~758557) - Location: Not specified - Photos: 4 - [Harry res.](https://www.houzz.com/hznb/projects/harry-res-pj-vj~171007) - Location: Not specified - Photos: 6 - [Fisk Res](https://www.houzz.com/hznb/projects/fisk-res-pj-vj~574827) - Location: Not specified - Photos: 9 - [Gaylis res.](https://www.houzz.com/hznb/projects/gaylis-res-pj-vj~171010) - Location: Not specified - Photos: 10 - [Casa de Cardif](https://www.houzz.com/hznb/projects/casa-de-cardif-pj-vj~872704) - Location: Not specified - Photos: 13 - [Lam Res.](https://www.houzz.com/hznb/projects/lam-res-pj-vj~148032) - Location: Not specified - Photos: 6 - [Katz / Jacobs res](https://www.houzz.com/hznb/projects/katz-jacobs-res-pj-vj~147292) - Location: Not specified - Photos: 5 - [Casa de la Costa](https://www.houzz.com/hznb/projects/casa-de-la-costa-pj-vj~1426793) - Location: Not specified - Photos: 11 - [El Mirlo](https://www.houzz.com/hznb/projects/el-mirlo-pj-vj~758553) - Location: Not specified - Photos: 7 [See all 14 projects](https://www.houzz.com/professionals/landscape-contractors/demaria-landtech-inc-pfvwus-pf~1199911720) ## Ideabooks - [johns favorites](https://www.houzz.com/ideabooks/28429671/list/johns-favorites) — 19 ideas - [jonny075's ideas](https://www.houzz.com/ideabooks/6335697/list/jonny075-s-ideas) — 89 ideas [See all 2 ideabooks](https://www.houzz.com/ideabooks/users/demarialandtech) ## Community Q&A **Q: ground cover plant** *(in Photo Questions)* Hello what is the plant that is growing in between the stone?
