"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!"

"Bryan from level Engineering was very helpful and was aware of our time line. We really appreciated his work."

"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."

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

"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!"

"From our very first meeting I knew these were the right people for our project. We added a second story to our home in El Monte and they designed it so beautifully that it doesn?t look like an addition at all. Neighbors keep asking who our architect is."
