He responded quickly to my inquiry about needing a survey, his crew who came out to do the survey was very friendly and provided me with a lot of information, and his price was extremely fair for the work performed. I highly recommend this company, and have even passed along his information to my architect to refer clients to in the future!"

"I have nothing but wonderful things to say about this company and every single person who works for them. It all began with the designer, Liz. She came out talked to me about my ideas, drew some plans and then provided me with a detailed, to scale drawing. We fine tuned things together and then she did the renderings. OMG, my dreams for my yard in pictures! A month later we were getting started! From the beginning with removal of existing landscaping to now I am beyond pleased. The crew is awesome, Dee the owner is here on a daily basis to check on progress and answer my questions. If it's not raining they are here at 7:00 am and work tirelessly all day. They are friendly and professional. I will post pics when the job is completed but for now you can see some of the renderings. Do not hesitate to hire this company. You will not be disappointed. As a note best way to communicate is with email as they are out working 99% of the time. Response to email is very fast! I just posted two pics of job in progress. I will post more when everything is completed."

"Hutch was professional and personable , easy to talk to about my design for front yard. His experience in design suggested minor adjustment of my idea/drawings but willing to landscape any way of my preferences. His contract was thoroughly itemized and didn’t add any additional “surprise” costs. Payments were installments as project progressed. Hardworking Crew stayed on expected timeline. Hutch came by every day to supervise progress of our landscaping. Our front and backyards were transformed from weed fields into beautiful landscaping. Removed weeds and unwanted plants, prepped surface, laid weed barrier and installed Artificial turf in backyard, laid pavers and stone walkway. Transformed front yard into rock riverbed surrounded by plants accented with boulders, and installing drip system. Planted border shrubs and a rose garden. Lined walkway and rose garden with pavers matching our flagstone. Our sewer line needed realignment which Hutch arranged to be repaired. Other company estimate quotes were either vague, didn’t itemize, or way over priced. Offered a few addresses for us to drive by to see his actual work which helped us on our decision to work with Hye Turf Design. I would highly recommend Hye Turf Designs. Thanks Hutch !"

"Excellently well! Sandy helped me coordinate the inspection expediently. We were on a tight timeline and she pulled some strings so we could get the inspection done in time. Our inspector/structural engineer, Erinn, was personable, thorough, knowledgeable and timely. I highly recommend him and Alpha Structural!"

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."
