"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.

"Let me tell you about Amir he is a stand up and honest guy!! When all architect companies wanted to take me for thousands of dollars Amir instead gave me the tools (knowledge) of what needed to be done to get the site and floor plan done for the city. You don’t meet many business people that will give you honest free advice so Amir is greatly I meant greatly appreciated for his assistance and guidance in getting my site and floor plan completed for the city. Will definitely work with Amir again!!!!"

"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!"

"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."

"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."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."
