"Pristine Construction handled everything from design, city permits, construction and any extras we needed.  Pristine has a crew of employees and they only take a limited number of jobs so they can provide quality service to their customers.   They usually deal with referrals by former clients and are constantly busy.  Once we met Nathan and saw his level of commitment, Pristine is well worth waiting for!!
Nathan Moses provided the design.  He spent 3 hours with us at the appliance store to select the bathroom hardware, he spent an hour with me at the window store selecting windows and doors and he spent about 2 hours with us at the tile store selecting tile for the bathrooms............all about 1 1/2 months before we even began the project.  They only had a $1000 retainer and he spent all of this time with us!  This is the level of commitment you get with Pristine!
As with any older house you can expect the unplanned or unexpected.  We had to replace the sewer system because it was leaking,  fix broken drainage pipes and add french drains but at each step, Pristine said, "No problem" and had a worker on site the next day.  We didn't think the AC was strong enough to cool our western exposure bedroom, Nathan had the AC guy out the next day talking about solutions or removing our reservations.  We thought the room needed a third coat of paint in one room, no problem.  Everything was perfect.
As I mentioned above, Nathan Moses and Mike Malka are fantastic.  Mike will be onsite every day once the construction moves 'inside'.  We were fortunate to have both Nathan and Mike come to the site every single day that workers were here.  
Pristine took care of the architect plans, city permits, inspections and coordinating everything.   Sharona would call every day to tell us what was going to happen the following day so we always knew what to expect.
We decided to add a spiral staircase and deck on top of the bathroom, Nathan researched and found comparative prices for the staircase.  We ended up going with a company because we just connected with the owner from the start!  It turned out to be a friend of Nathan....should've known!!  Another advantage with Pristine is you pay direct for the tile and appliances using their contractor's discount and don't get charged an additional 20% as some contractor have done in the past.  Why should I pay 20% more to the contractor depending on the cost of a bath tub?  Pristine doesn't do that!
Their work is outstanding! and they stand behind the work  For example, I selected the tile for the shower nook and Faustino spent hours putting it together but once done, I didn't like it at all.  The Pristine team says, "We want you happy."  He came back on Sunday, took out all the tile and manually cut small pieces based on a custom design I drew and didn't think twice about making it absolutely perfect!!  Amazing teamwork and wonderful group to work with!  (And we weren't charged extra!!!!)
You will love their work, their staff and entire team of professionals.  There was never a disagreement or negative response.  The team has a positive attitude, great work ethic and outstanding results.  We hesitated for 15 years about doing this room addition because we heard terrible remodel stories!!   If only we knew about Pristine Construction but sure glad we were referred.  They are the best!
 The cost that I listed above is for room addition, additional closet built in master bedroom and guest room, new addition walk-in, complete remodel guest bath, new AC in 4 rooms, new sewer line, city permits.

"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!"

"Very experienced structural engineer who could analyze our rooftop deck and give us a plan for doing the roof and hotub of our dreams!"

"Having built many projects and delt with many engineering firms in my business, I’m very impressed with how quick and professional they are, I personally met with Peter himself, a class act gentleman all the way! I would recommend him and his team without a doubt, look forward to giving them all my projects from now on, apricate all you and your team are doing for us. Thanks guys!"

"I highly recommend Franco and Rene as skilled architects. We hired them to design plans to remodel our kitchen, bathrooms, and design a new master bathroom and bedroom that we are adding to our home by converting an existing space. After meeting with them, they got a sense of our design aesthetic and the 3D renderings came out great. They were easy to work with, professional, and the work they produced was high quality. Exceptional customer service and they are very responsive. They also handled filing our permits. You will be in good hands with Franco and Rene."

"Tolga was very professional and far exceeded our expectations. He drew up our structural plans very quickly and was easy to reach whenever we had questions. I would highly recommend TY Engineering to anyone looking for a structural engineer, and if I need one in the future they will be the first I call."

"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!"

"David and his team did a great job with the drawings for our room addition remodeling project. We added a large section to the back of the house and created a 1 bedroom and a bathroom room with a small kitchen. David came up with comprehensive blueprints for the entire remodeling project, and he also generated a great 3D renderings of the addition for us. He also got for us all the permits from the city."

"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 !"
