"The experience of working with Pristine Construction greatly exceeded my expectations. At least one of the owners was on site every day, and from the moment construction started they did not skip a day of work. Everybody was friendly and knowledgeable. I can't imagine hiring another company in the future."

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 recently hired G&L Design Building and Landscape for a major outdoor project, and I couldn't be more thrilled with the results! From start to finish, the experience was seamless, professional, and truly impressive. Dror, the owner, is a visionary. His attention to detail, creativity, and commitment to quality were evident in every phase of the project. He took the time to understand my vision and brought it to life even better than I imagined. His team built a stunning retaining wall, installed lush, vibrant turf, and laid down beautiful interlocking pavers that completely transformed the space. On top of that, they planted an incredible selection of trees and flowers that added the perfect finishing touch—absolutely breathtaking! The crew was punctual, respectful, and worked with great care and precision. It’s rare to find a team so dedicated and passionate about their craft. If you're looking for top-tier landscaping and design, look no further than G&L Design. Dror and his team are the real deal—professional, talented, and a pleasure to work with. Highly recommended!"

"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 !"

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."
