"Our basement went from a dark storage area to a cozy family room and home office. The remodel was smooth from start to finish. Great communication, thoughtful design ideas, and skilled workmanship throughout."

"The finished work turned out beautifully but the length of time it took the crew to complete the job could have been better. The project manager was great to work with and very responsive however there are a couple of small details that I am waiting for them to resolve."

"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project."

"It was a challenging time to undertake this project between COVID, engineering errors (not the builder), labor shortages, and the price of lumber. I would not say it was easy, but the end result is a very well built, comfortable, attractive, and energy efficient living space. I learned a lot from this project and provided feedback to the contractor about what I didn't know about the process when we began and what others would benefit from. One key item is a clear list of what the "finishing" materials are and a schedule indicating when these materials are needed. I recommend that anyone working on a building project of this intensity insist upon a detailed list as part of the contract and in advance of the work beginning. Since our work was done, this contractor has hired two additional people to focus on those types of needs. The people performing the labor were always polite, friendly and respectful of masking and social distancing. We felt comfortable with them around our home. One thing that could have been better is more orderly disposal of materials and separation of recyclable and non-recyclable items."

"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 !!"

Customers say: Quality work

"At our first meeting, it was clear to me that John Hagenbach was a very honest and hardworking individual. His understanding of my goals and budget was exceptional and together we were able to map out the project to add a bay to our garage and to renovate and expand the apartment above our garage where our daughter, son-in-law and two young grandson's live. Having John and his crew at our home was more like having skilled family members working to insure we would have 100% satisfaction. They exceeded our expectations on every level including price, schedule and exceptional workmanship. It should also be said that this was accomplished during one of the severe weather we experienced this winter. FIVE STARS understates the performance of John and his team of craftsmen."

"It's difficult to trust contractors these days. We had a bad experience in the past with another contractor and we were very hesitant to use one again. However, we decided to give Tech Line Construction a chance because our friend recommended them. We are so glad that we did! They painted the exterior of our house and handled a bigger project for our property. I admire how Luis always kept us in the loop and he was always available to answer our questions. We'll pass the word to our friends and family about this company. They're the real deal!"

"Sol was the Unique Home Design & Remodeling project manager for the recent kitchen and bathroom renovation that we recently did and his team of skilled and hardworking did a wonderful job. We greatly recommend Unique Home Design & Remodeling and mainly Sol, The working crew and the office staff that was involved in our project and we will hire them again for any additional remodeling project in our house. Sol was the project manager on both remodeling projects (kitchen and bathroom), did a perfect designing job for the kitchen space by using most of the existing space with features that we needed and wanted for a while now. From start to end, the extra attention that Sol put to all the details of both projects was more than what we were looking for. He always gave wonderful ideas and suggestions and he made sure that we are happy with all the decisions about both renovations. We love both projects very much! The kitchen and the bathroom got a completely brand new look and they are very functional for our needs. It makes us very happy each time any of us walk into any of them!"

FAQs for addition to existing structure building service projects in Sunol, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
