"I am sorry it has taken me this long to write my glowing review of Pristine Construction! They completed a kitchen remodel for us in February and we are thrilled with the results. In the past we have had some nightmarish experiences so we were reluctant to take this project on. But after reading all the positive reviews and meeting the team in person we moved ahead and we are so glad we did. From the start, Nathan patiently worked with us to draw up the plans, scope of work, budget and timeline. His expertise and suggestions made all the difference in ensuring we made the most out of the space we have. He met me at the tile store to select the backsplash, he has a good eye for design and style. Once the project got underway Mike was on site overseeing their own personal crew for flawless execution. Mike also lent his expertise in helping me to select final touches like drawer pulls, kitchen faucet and lighting. The crew were courteous and neat. Every day I received emails or phone calls from Emma in the office updating me on what was happening, who was coming and going, when payments were due, etc. I felt completely looped in and reassured at the overall coordination of all the people involved. This is a top notch company. The project was completed on time and on budget. We are thrilled with the results. Even my children's friends remark that it looks like an HGTV remodel! Nathan and Mike are honest, detail oriented and very professional. It was a pleasure to work with them. We would recommend them to anyone and already have!"

"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!"

"Structural engineer came by to confirm if wall was non-load bearing as suspected. Confirmed, can now move on with my project."

"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!"

"Office personnel knowledgeable and patient and professional and courteous. The Engineers' who arrived at my thank you. Very professional and explained all questions I asked thoroughly. Great job. Will recommend."

"The architect was professional, knowledgeable, and responsive throughout the project. Communication was clear, questions were addressed promptly, and the design met our needs and expectations. Their attention to detail, understanding of code requirements"

"My husband and I hired G & L Design to create a Tuscany inspired backyard which is comprised of pavers stone patio, custom outdoor fireplace, and soft landscaping. They beat out several other landscaping companies because their willingness to work with our design vision and preset budget, as well as their stellar reviews on Angie's List. Rick Shadley, the landscape architect/designer, worked all of our aesthetic inputs and personal styles into his ultimate amazing artistic yard design. He truly captured our wish of reliving the Tuscany trips we took by giving us a Tuscan inspired garden that looked like a page torn out of a landscaping magazine. He was one of the most humble, gracious, and talented designers we have had the pleasure of collaborating with. The only drawback my husband and I saw was the company's decision not to involve him during all the construction phases of the project. I am sure that he would be more than happy to help if he was called upon -- we just hoped his involvement was already part of the built-in processes. Dee the project manager showed up not once but sometimes numerous times a day to monitor and guide the progress of our project. He was very knowledgeable and easy to work with. He decided to deliver us a custom built fireplace (much sturdier than a pre-fabricated version) after discovering the windy nature of where we live. Based on our experience and observations, the company also hires reliable and hardworking workers. Since the completion of our yard, we have received many compliments from family and friends alike. As with all projects, there were challenges. The company would have received all five stars if it were not for the minor time delays (partially it was caused by holidays and weather challenges). My husband and I will undoubtedly host many parties and spend a lot of free time enjoying the garden and be virtually transported back to our favorite Tuscany spots. I would definitely recommend G & L to our family and friends in the future!"

"Couldn't be happier with the project from start to finish. Same day quote, with work following quickly after that. Tile installer was outstanding."

"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."
