Comments: One would be hard pressed to find a contractor that would top the quality and service offered by Kurt, Steven, Gaspar and Alex with KT Construction. Our project was a complete renovation of our backyard including solid patio cover, 1,000 sf of pavers and complete re-landscape. I was provided a color copy of the design they suggested which laid out sprinklers, drains, patio cover fire pit, pavers etc. They were very patient while I was delayed multiple times by our HOA but once approved, they were here every am at 7:00 and did an outstanding job of clean up every day before leaving. The project was completed exactly on time. My wife and I could not be more pleased with the entire process and end result. Kurt, Steven√ ¬Ę√ ¬ √ ¬¶. Please express our gratitude to your entire crew. Anxious to have you out to tackle the front yard!!!!!!!

Comments: 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.

Comments: 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.

Comments: 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.

Comments: 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.

Review Date: 08/22/2019 | Author: Nancy W.

Comments: 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.

Comments: 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!

Comments: 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.

Review Date: 02/21/2018 | Author: Richard P.

Comments: 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.

Review Date: 01/12/2018 | Author: Cathy A.

Comments: 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!

Comments: I am extremely pleased with how my yard looks! After 20 years my entire yard needed renovating. I was hesitant to use a landscaping company due to our past unpleasant experiences with other companies. But we have a third of an acre and needed professional help. KT Construction was a dream come true. Bob was wonderful to work with, very capable and knowledgeable. He understood what I wanted to do with my yard and worked with me to bring my vision to life. Alex and the entire crew were skilled and conscientious workers. Now we are thoroughly enjoying our yard! One zone is a beautiful orchard and edible garden, another zone features native California plants and the last zone is a park-like area. And all of it glows in the evening with striking beautiful new lights. I highly recommended this company.

Comments: Excellent job. Replaced landscaping of our newly remodeled home in Corona del Mar. Steve was very knowledgable about what plants would work best. Alex and his team were fabulous. We are very pleased.

Review Date: 05/09/2017 | Author: Robert P.

Comments: Landscape project involved a residential landscape replace & refresh for our 27 year old existing landscape -- front & back yards. Excellent planning and execution of project, on time, on budget. Steve was excellent listener about our needs and recommended an attractive, thoughtful plan. Project involved removing virtually all plantings in beds, significant clean-out / remove work - including several tree & stump removals, prepping beds and installing new plants. Also created new feature planting areas in front lawn; integrating project with existing mature trees / palms which were kept; fun & creating planting of succulents into new pottery, and additional work. Alex and the crew had versatile skills and worked hard, cleaned up at the end of each day, and were very professional. Neighbors commented positively about the results. Overall, recommend them highly.

Review Date: 11/19/2016 | Author: Bernard P.

Comments: Great team of workers, led by Chuy and Alex. The entire team worked extremely hard throughout a multi-month very big project, where we did a complete rebuild of our front and rear yards. Pavers was a significant part of it and they look great with many positive reviews from neighbors and friends. Also, we had a number of unforeseen additions and they were extremely fair and reasonable with the change orders. I would highly recommend KT Construction.

Review Date: 10/04/2016 | Author: Gary D.

Comments: We hired KT Construction to build a patio and install a spa in our back yard. Bob, Alex and the team were exceptional. They came on time, worked hard, kept the project moving, took care of issues right away and always cleaned up before they left for the day. They did what they said, they were honest and best of all, the patio and spa look awesome. We haven't always had great luck with contractors, but we will definitely call KT back for our next project.

Review Date: 08/26/2016 | Author: Elizabeth C.

Comments: Thanks to KT Construction, we have a showcase backyard! Everyone on Bob's team was outstanding. They worked very hard and the craftsmanship was excellent. Very nice people to deal with and amazed they finished a 3.5 week job in only 9.5 days! Rockstars! I would highly recommend KT construction to anyone who is planning on doing a landscape project- large or small.

Comments: KT Construction did an EXCELLENT job with my backyard remodel far exceeding my expectations! Bob was the person I worked with to plan the project and was very visible from the start of the project until its completion. Bob has over 30 years of experience and was very helpful in making recommendations and helping us visualize the end result before a shovel ever hit the ground. The entire crew (Chewy, Tony, Alex and others) were exceptional and very professional. They promised the project would be completed in 3 weeks and delivered a couple of days early. I researched many local Orange County landscaping companies and selected KT Construction based upon the reviews I read and after meeting with Bob. The cost for the project was very fair based upon the scope of the effort. If you are looking for a company who will deliver what they promise at a fair price then I would highly recommend KT Construction.

Comments: We have a rental in OC that needed some landscaping on the back slope. We met with Bob once and I knew right away we would be in good hands. My father had a xeriscape landscape business when I was a kid so I was somewhat familiar with being able to tell if KT had expertise. Bob absolutely knows his stuff and has been in the business a long time. After our initial visit I didn't have to go on site once. (We live 3.5 hrs away.) KT's crew cleared and replanted a beautiful selection of plants that are going to fill in very nicely. Various flowers should bloom throughout the year too. Sprinklers were installed along with a timer that will make the slope essentially hassle free. To top it off, Bob will check on the slope in a couple of months to make sure everything is looking good. Definitely would recommend this business.

Comments: We are just completing a MAJOR hardscape/landscape project using KT Construction and we have been very pleased from the very beginning of the project right through near completion. Our project manager, Steve has been very responsive and easy to reach. He has done a wonderful job of picking out drought-friendly, yet attractive, plants as well as keeping his foremen and workers on task. They are finishing ahead of schedule. No hidden costs or fees. The workers are very professional and our neighbors keep telling us how polite they are as well as how clean they have kept the jobsite. These guys are honest, hardworking and very competitively priced! We couldn't be happier with our choice to hire this team!

Comments: From start to finish KT Construction did an outstanding job on our backyard remodel. Bob Zeis and Steve Scharf provided top notch customer service, always available on site and on the phone when we had questions or suggestions. The work crew was at our house every day, several neighbors remarking how unusual that is since they'd worked with other companies that hadn't been as reliable. Bob and Steve kept the job moving along and we were always informed of what we could expect that week. The construction crew was very polite and conscientious, arriving each morning on time and leaving the job site with everything put away in the afternoon when they finished for the day. We are completely happy with the finished product, so much so that we are planning to work on the front yard with KT Construction again this spring. For full service landscaping from the design to the construction phase of both hard and soft scape I strongly recommend KT Construction.

Comments: Bob arrived promptly to provide a quote and was understanding when I wanted to visit with 2 other contractors before making a final decision. He surveyed the property helped with ideas for both the front and back yards keeping my budget restraints in mind. His crew was courteous, hard working and neatly stored tools and equipment in the backyard at the end of each day during the project. A few follow up items regarding the sprinklers were handled timely by Alex who actually left me with his personal cell number should I have additional questions. Great job and I would be happy to recommend them to neighbors and friends.

Comments: We were contacted by Bob, who came out the same day to survey our property and provide us with an estimate for some landscaping and patio masonry repairs. Within one day of providing the quote, Bob had his workers on site and the repairs were completed that same day! Bob demonstrated superior knowledge and experience pertaining to the work that needed to be done. We were impressed when Bob came on site a week later after a rain storm to check on the operation of the drainage repairs. Great performance and followup!

Comments: I only rated a 4 for now becase we are not finished yet because the stone that I want is on back order. What is finished though looks spectacular. I worked with Steve Scharf and he took my designs and made them come to life. They quoted the project, started on time and have been quite willing and flexible to my wants and desires. I get compliments on their work everytime I'm outside. Can't wait for the stone to arrive.

Comments: The work was excellent. The workers were polite and cooperative. There were some delays, due to extenuating circumstances, including extreme heat which made it impossible to pour concrete or to work long hours in the heat of the afternoon. After they finished, they cleaned up the work site. Overall, we were happy with the results and would recommend them to others,

Comments: Created brick hearth for fireplace. Workmanship was outstanding however were not able to match new bricks to existing bricks on the face of the fireplace. Contractor completed work without notifying me first about the different brick. Would have appreciated them running the issue by me first before beginning the work. The work however was great - very detailed; and the contractor was on time and completed the work within a few hours.

Comments: : Bob was the third landscaper to come out. Another guy was the first, and he wanted to do what he wanted to do, not what I wanted, and talked to me as if I just wasn't too bright. He never got back to me with an estimate. The second was a woman who talked about herself the entire time, never listening to a word I said, and she also never got back to me. Then came Bob - he listened to what I wanted, made his suggestions, and gave me a quote before he left. And I love the results.

Comments: Working with KT Construction was a smooth and rewarding experience. Steven Scharf designed our landscape planting with all the important elements of not only the yard, the weather and the needs of the plants for each and every area, but for our tastes and desires. As the homeowner, we are very pleased with our beautiful new plant-scape environment and highly recommend Steven Scharf and the KT crew!
