    5.0 Paul K. San Clemente, CA

    We had an excellent experience with KT! Steve, Gaspar, Chewy were all true pros. We did a complete back yard remodel and we could not be happier with the end product. I am a super picky customer and Steve and the team made sure the everything was just the way we wanted it. Thank you KT, we were roasting s'mores in our firepit just last night.


    Steve was great to work with. He came right out and the job was done and completed within the timeframe given. They cleaned up everything every night and the plants he picked look great. Great service, done quickly and professionally. I would definitely use them again.


    I cannot say enough about Steve Scharf and his lead (Gaspar) at KT Construction. I hired KT to pull-and-replace all the landscaping at my home in Laguna Niguel in September 2020. Steve gave me such confidence during our first meeting that I asked him to draw the design (for new plants and irrigation) as if it were his own home. He quickly drew up the plan, reviewed it in detail with me, and scheduled the work for 3 days later. The work, including sprinkler replacement and modification, was done quickly, cleanly, and was overall top notch! Steve has already drawn a plan for us to complete the 4th and final phase of this project, which we will begin in May 2021. I can wholeheartedly recommend Steve Scharf and KT Const to anyone seeking a landscape design and replacement.

    5.0 Joelle K. San Clemente, CA

    Ive worked with several companies over the years, both landscaping and indoor construction. KT is by far the most responsive and helpful company I have worked with. We ended up adding several items to the list of relandscaping our front and backyard once they got started due to the fact we were so happy with the work and speed of the process. Steve was our designer and he made sure all of the final decisions resulted in what we were looking for, and was cost effective. Everyone shows up to work on time, and even with multiple added projects, they are still ahead of schedule. Would recommend over and over.

    Steve Scharf is personable and professional. The job consisted of removing over-grown and dead plants and replacing them, installing synthetic sod, seeing to it that our outdoor lighting system was working again as well as improving our irrigation. I was consulted about each aspect of the job. His team was knowledgeable and their work was excellent. They started the job when promised and finished two days early. I would use their services again in a heartbeat and recommend them without hesitation.

    5.0 Carol A. Laguna Niguel, CA

    This is a follow up review. We used this company 2 years ago and were thrilled with the professionalism and overall work. Fast forward to now, we had a cracking retainer wall. 1 single phone call to Steve (the project manager from 2 years ago) and within 2 weeks an enormous crew of men came and tore out the large amount of concrete did some major reinforcing and finished the job in a week. It looks perfect! This is a SOLID company who stands fully behind their work. I was very pleasantly surprised by how little effort it took to get such a great resolution to the problem. Use this company! They will make your project worry-free! Thanks so much KT Construction and especially Steve!

    5.0 Kathryn M. Laguna Niguel, CA

    Steve and everyone at this company was a pleasure to work with. They were responsive, reliable, on time and did an excellent job helping us design and redo our entire front and backyard landscaping. We are comfortable referring all our friends and neighbors to KT Construction.

    5.0 Richard P. Laguna Hills, CA

    My job was a complete redo of hardscape and landscape. The job was finished in a timely manner. Alex was a pleasure to work with and he has returned several times to address landscape lighting issues. I left the selection of plants up to Bob and was pleased with the results. I am happy with their work and would recommend them to others.

    5.0 Cathy A. Santa Ana, CA

    They were hard working and completed the project in a timely manner. Steve and Alex were both great to work with. Willing to listen, make changes and respectful of our property. We couldn't have been happier with the day to day work and the end result. Would hire them again in a heart beat!

    5.0 Carrie B. Ladera Ranch, CA

    They are talent good workers who clean up after each day and nice and respectful of your property. Bob is extremely well educated on landscaping and plants. Great group of men I would use them again!
