5.0 Agnal K. Campbell, CA

First of all, these guys are rockstars. I never thought that I will say this about contractors - but they really impressed us with their professionalism and quality of work. We bought a new house with a big yard for our kids to run around (realizations during the pandemic), but it meant that we had to compromise on the quality of the house interior. It looked really old and didn't look renovated after it was build in the 60s. I started talking to general contractors to get it remodelled and was shocked by the timelines and prices being quoted. I found Ohad (owner of Quartz Construction) via yelp reviews and what struck me most was that everyone was commenting on his clear communication. We had done a remodel of our townhome in the past and it was not a great experience since the contractor kept changing timelines and prices in the middle of the job. My wife and I went to their office and had a detailed conversation with Ohad on what we were looking for. We had just a vague idea of what we wanted and this is where Ohad really helped us. He worked with us to create a plan on how we can make the home better and he even played the role of the designer to change the layout to create a new bedroom and bathroom. Post that, he drafted up everything and gave us a detailed quote on everything. 1. Remove 2 fireplaces and an indoor bbq pit within the home. 2. Change complete flooring. 3. Remove the popcorn cieling (and asbestos) and put new cieling. 4. Complete remodel of kitchen including structural changes. 5. Complete remodel of 2 bathrooms. 6. Construction of a new room and bathroom (with structural change). 7. Remodel the laundry room and guest washroom. 8. Recess lights across the house (close to 80 + recess lights across the house). 9. Painting interior and exterior. 10. New sub-panel for appliances. 11. All the required permits for these. Ohad a quoted a very reasonable price for all of this and he quoted 2 months to finish the project. I was a bit shocked, but he was very confident about it. We really liked the way he communicated and had an open discussion about everything, so we decided to go with him. Ohad had promised us that we will see progress in our house everyday and he kept that promise. His workers are honest, hard working folks and we were really impressed by everyone - especially Omar who was the worksite supervisor. The workers showed up everyday on time (8 am or earlier) and left late evening by 7 pm. They left the worksite so clean after every day's work that we used to wonder whether they were planning to come back the next day :-). Even our new neighbors were commenting about the punctuality and asked us for the contractors phone number for their remodeling (without seeing the interior, just based on the punctuality). We were expecting it to at least take 3-4 months and were prepared for the wait - but the entire project finished in 2 months a 1 week ( 1 week over the agreed timeline). And, the reason why it took 1 week more was since we added exterior painting and slanting roof+insulation for our new bedroom at the last moment. Since almost everything at our place was new, there were things to be fixed and reconfigured after we moved in. Anything we called and asked for was done the same day or the immediate next day. Everyone coming in and seeing the house cannot believe that it was done in 9 weeks (and within the budget) and a lot of my friends are now planning remodelling keeping Ohad and Quartz construction in mind. Ohad always says that he is "talking out loud" so that there is no confusion. It is his way of making sure that everyone is on the same page and there are no surprises. He is brutally honest and that is the best quality a contractor should have. This was the biggest remodeling we ever did and we were expecting a grind - but it was a breeze thanks to Ohad and his men. Highly recommended !!

I hired Quartz Construction for a Master bathroom remodel due to a cracked shower pan. They were very accommodating with preserving what we could to minimize costs on finished materials. Provided great vendor recommendations. Evaluated invoices for competitive prices for materials picked. Their quote was competitive with other contractors. Happy with their craftmanship and thorough attention to detail. They were promptly responsive to each call, text and question but most importantly kept me in the loop on everything. Great customer service. The workers cleaned up after themselves, they were polite and arrived promptly every day.

This is the 4th time I've used Quartz Construction and they gave me a competitive quote for a complete renovation of our old bathroom. As always, Ohad, (the owner) provided guidance on all aspects of the job: materials, design, vendors and schedule which was 3 weeks to complete the job. Ohad's team did a great job and demonstrated outstanding workmanship across all phases of the renovation which included: flooring, tiling, fixture installation, electrical, plumbing and very importantly ensuring all the detail work was completed to our satisfaction. The project was completed on time and again Quartz confirmed that they are true experts in this field.

5.0 Amy H. San Jose, CA

Excellent workmanship and professionalism from Ohad (owner), Luis and David! Ohad is very thorough going over the details of the project, cost and time. Luis and David were on time, worked extremely hard and cleaned up the site at the end of every day. Luis would let me know immediately if there were any issues (a couple and very minor) and the quality of workmanship is amazing. I had all my cabinets, countertops, backsplash tiles and fixtures ordered and in stock (with guidance from Ohad) before work began and the entire process took two weeks!

5.0 Lisa B. Saratoga, CA

We are so impressed with Ohad and Quartz Construction s professionalism, skill, and perfectionism. Ohad built a pergola and installed it above my garage and installed IPE wood siding to modernize our home. His team also installed new lighting to our exterior. Quartz construction works quickly, efficiently, and cost effectively. We recommend them to everyone!!

I contacted Quartz Construction to check a leak in my bathroom. Ohad (owner) did an immediate inspection under the house and discovered a bad leak under the toilet bowl. He took photos and video for insurance purposes. Ohad provided a competitive written contract which I approved and work commenced immediately to fix the leak and repair the considerable damage. Quartz did a great job and the overall workmanship was excellent: flooring, tiling, fixtures and attention to detail. They are truly experts in this field.

5.0 Barb W. Sunnyvale, CA

We were very happy with our experience with Quartz Construction and remodeling. When we contacted them for an interview andestimate, they replied immediately and were able to come over in a few days. We remodeled our large master bathroom. In a nutshell: Quartz was everything we hoped for in a contractor/remodeler they were professional courteous kind trustworthy knowledgeable reliable helpful fast easy accessible skilled and great at communicating and cleaning and work unobtrusive. We love our new bathroom!

5.0 David E. San Mateo, CA

Ohad and his crew completed both a major bathroom remodel and replaced an old balcony in our home much faster than I thought would be possible. Ohad made some extremely helpful suggestions about how to rethink our initial plans and the resulting layout is wonderful. The results were beautiful, and they were extremely responsive to any concerns, questions, or requests. When there were small issues, they went above and beyond in an effort to make things right.
