""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!

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

"My residential construction project was abruptly put on hold when a city inspector required a survey to verify the property boundaries. Unfortunately good surveyors are in high demand (at least 4 weeks out), and Voorheis and Voorheis was no exception. However, after discussing my job with Jeff, he thought he'd be able to work it in very soon between other clients. Jeff patiently answered my questions, and I ultimately felt confident to hire them for the survey. I was really happy with their thoroughness and professionalism, and ultimately the city inspector was satisfied and approved our setbacks. Thanks to Voorheis and Voorheis for getting my project quickly back on track with their excellent and timely work!"

"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."

"Amir is A1 his service was on time and on budget I remodel my whole house , I’m happy and I recommend thanks Eagle view remodeling and Amir"

"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."

"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."
