""It's like walking into a magazine" as stated by two different visitors to our newly remodeled home by Pristine Construction. Nathan and Mike, owners of Pristine Construction abide by the premise that your home is their home, as shown by their work ethics and end results. We had interviewed several contractors but we chose Pristine because of the initial interview that immediately gave us confidence that this company would take care of us in a timely and respectful manner. Due to a plumbing leak in our home, our hands were pushed to finally redo a portion of our home.  Our project included, a total demolition of our kitchen, down to the studs, addition of a powder room, and an addition to the master bedroom of a master closet and master bathroom.  It was a huge project! From the beginning, Nathan and Mike visited the sight every day and their sub-contractors showed up on time and cleaned up before leaving. Whenever, we needed to contact Nathan or Mike, they always answered their phones.  Their Office Manager, Shelley, called us, at least three times a week to check in with us.  The personal touch does still exist!  Nathan took us to his vendors to pick out plumbing fixtures, appliances, tile and windows and doors!  The vendor's products were top notch but budget friendly. On April 13, 2015, three months to the day of starting, our huge project was complete!  We now have a stunning white kitchen anchored by engineered hardwood floors, gleaming glass backsplash, beautiful soapstone counter tops, a huge island and pantry. We have more storage than we know what to do with.  The cabinets were personally made by a craftsman who knew how to handle our cove ceiling. The lighting in the kitchen is excellent and the under mount LED cabinet lights add such ambiance. Our master suite is a peaceful retreat with soft gray walls, a huge walk in closet with craftsman made cabinets and the bathroom, oh the bathroom!  The floor is marble, counter tops and backsplash a stunning quartz, flanked by another craftsman made linen cabinet.  The frameless shower is exquisite, with Grohe fixtures, glass tiles and a pebble floor meeting the custom built seat. A pocket door now encloses the toilet!  The exterior stucco of our house was also redone due to our addition of new, energy efficient windows.  Of course, we added many additional items to our original scope of work due to the fact that we saw the incredible work of Pristine Construction.  As other reviewers have noted that Nathan and Mike become a part of your family, so it has been for us.  We could not recommend Pristine Construction more.  We will actually miss seeing them each day.  Thank you Pristine Construction and all of the Sub-Contractors for a job, more than well done!

"Working with A. was hands down one of the best decisions I made for my remodel. From our first meeting, they really listened to what I wanted and brought ideas to the table that I hadn’t even considered. They found the perfect balance between style and functionality, making my home not just beautiful but also incredibly livable. Throughout the process, they were easy to communicate with, super responsive, and always on top of things. Remodeling can be stressful, but they made it as smooth as possible. The attention to detail was next level—I kept noticing little thoughtful touches even after the project was done. I couldn’t be happier with how everything turned out. Andi was friendly and helpful. If you’re looking for an architect who genuinely cares about their work and their clients, A. is the way to go. Highly recommend!"

"Jeff was great to work with! 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 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!"

"Design1 Studio designed our kitchen remodel in Glendale. They maximized every inch of our small kitchen and came up with a layout we never would have thought of. The permit drawings were detailed and our contractor said they were some of the cleanest he’s worked from."
