"Our family decided to build an ADU. We got three estimates they where all kind of close but My Construction Group responded to every question sent out very knowledgeable professionals. Made us feel really comfortable about their building strategies and customer service. They will not only give you what you want but better than what you expected. I promise, you won't regret it!"

"Karol and his crew are very talented, efficient builders. We hired Karol to build a composite deck to compliment the pool we had installed in the back yard. It turned out beautifully. He is a great communicator and listener, prompt and reliable."

"We just finished to build an ADU in the backyard with ON Design & Remodeling. In the beginning we met Aviv and he guided us with his team along the design process. They helped us to get the permit faster and choosing all the visible materials before starting the work. During the construction we received weekly updates regards the process so we always knew what to expect. We build the unit for my parents and they are so happy with their new small home, and to share the yard together with us. Currently we are in the planning process to remodel our main resident kitchen with ON team, so obviously we are so happy working with this amazing team."

"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 went with Sky Tech Builders on a room addition. I decided to hire this company because they gave me very realistic offer, were available in short time and I also got some recommendations from my friends. The project started soon after we signed a contract and it went very smooth, there were no issues or hidden costs. Sky Tech Builders team was professional, efficient, quick and communication was great. They finished this project ahead of schedule, quality is superb and final product is excellent. I couldn't ask for more! Thank you!"

"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!"

FAQs for addition to existing structure building service projects in Santa Clara, 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.
