    Guest Bathroom
    Ollie S.

    My family started work with Extreme Home Addition and Art Vartanian back in 2018 on a large 2 bedroom, 2 bathroom addition to our house, and three years on we are absolutely delighted with the quality, communication and attention we received. Art put us in touch with a great designer, George Mendez, who drew up our plan ready for submission to the city, and when permits were approved, we started construction in 2020. The workers were respectful, helpful, punctual and their work was excellent in quality. We were so impressed with what a single team could do: foundations, flooring, roofing, electrics, HVAC, painting, tiling and plumbing. The prices that were quoted were extremely reasonable, and the work was done on time and with a minimum of fuss. On the rare occasions that we needed some flexibility with payments, Art was accommodating and understanding. Most of all, we were absolutely delighted with the communication we had with Art, who bent over backwards to accommodate all the changes-of-mind we had during construction. The team really worked hard to create as little disruption as possible, and our 3 year old child became good friends with the workers. Extreme Home Addition are an extremely professional company who do top quality work at a very competitive price. We would absolutely hire them again to do any and all of our future work on our home.

    I can't say enough about this contractor. Art and his team are outstanding. They are so fast, the work quickly and immediately and they are honest and trustworthy. Art gave a straight price from the beginning and kept his word. His crews were working first thing in the morning until late every day getting the job done. He did a two month bathroom remodel in 4 weeks and it's stunning. On top of that, during these difficult times we've had to call him for urgent services like electrical work, plumbing and he has someone at our house right away. It's helped us deal with the situation of being forced to stay at home during quarantine and avoiding losing power or electricity. I couldn't recommend this business more for any urgent home needs and also for remodel projects moving forward.

    Very please with Art and his team! Our kitchen remodel came out beautifully and the quality speaks for itself. They even went above and beyond with making sure previous plumbing & electrical issues were updated properly. Would recommend them if you're thinking of a small renovation or even a larger project!

    Thank you Art and team! We recently completed a total home renovation/makeover. Art worked with us from the very beginning. Rough drafts, design layouts, etc. When we were finally ready to move forward with the project, Art put so much thought and care into every detail. He equipped our home with new plumbing and electrical throughout and a brand neww HVAC system which our home never had. Art and his team Completely redesigned our home layout: new structures within, brand new everything from the kitchen, both bathhrooms, living, dining, bedrooms, garage/den, new roofing. The project took close to 10 months for completion, but was worth the wait. Art made the entire process stress and worry free.

    Bathroom framing (phase 1)

    With all the delays with house remodels due to the lack of supplies and contractors we had to be very selective with who gave our bathroom remodel to. After doing a lot of due diligence we decided to go with Extreme Home Addition. If there's two words to describe Art it would be "straight shooter". His skill set was noticed after a couple minutes of speaking with him. I've given him the canvas! He's taken pressure off my shoulders by communicating with my other vendors to make sure all pieces of the project are in sync. I'm extremely impressed with what I've seen so far. I'll post another picture once our bathroom is complete. As of now...absolute 5 star and beyond!

    The hallway. They added the pipes for the washing machine.

    we were looking to complete a second story addition above our garage and turn our recreation room into an ADU for my parents. we were very lucky to find Art and his team; Art and his team did a wonderful job, added the framing into our existing recreation room, changed the walls and added the bedroom, took care of the plumbing electrical and HVAC and did all the tile installation and the kitchen. I was impressed to see the project went so effortlessly. I have heard that materials are hard to find during these post pandemic times, but our project was completed without any distributions. I also loved how accessible Art was, when we emailed him, he always got back to us within hours and he and his team were great personalities to work with. one other thing about this team that impressed us was their tidiness. They did an excellent job of cleaning the area and keeping the materials away in nice piles. we have little children and they always play in the backyard and we never had any issue with any dust or dirt. we are hoping to work with Art again in remodeling our bathrooms hopefully in the near future. thank you Art and team for giving us a beautiful home! you are the best!

    Art did my shower and bathroom. Could not be happier with the end result. His workers are professional and clean. I would highly recommend.

    Ugly bathroom BEFORE Extreme Home Addition!

    I have a beautiful and crazy little hillside cottage in the Silverlake hills. My home was originally built in 1902... now I don't think our bathroom was 112 years old but it sure looked liked it. We HATED our main bathroom and we swore to remodel it the moment we bought the house. We got several bids on it, they ranged from $14K up to $30K. I found Art and Extreme Home Addition here on Yelp and gave him a call. He showed up like a day later and spent a good long time talking to me about my options, his ideas, my style, my budget, timeline. He was SO cool about everything and about $5K cheaper than anyone else with great reviews. He even loved up on my dogs a little which was awesome (yay, dog people!). We got started 10 days later and it was an amazing experience. His guys were efficient, Art was almost always around to discuss things with, I texted him a couple of times with crazy new ideas about stuff and he was always enthusiastic about it. Super high-quality workmanship, I feel like I got truly unique and fun bathroom that looks beautiful and completed on time and on budget. I could not possibly be happier about calling them.... I am thrilled about our new bathroom, our whacky gorgeous bathroom and I am definitely calling Art for our next project. Client for life! Thank you, Art!

He was straightforward, knowledgeable, and really took the time to understand what we wanted instead of pushing his own agenda. Building an ADU is overwhelming from the start.. But Avo really carried that weight for us. He dealt with the back-and-forth, and made it feel manageable instead of stressful. He kept us updated every step of the way and was always available when we had questions. We never felt confused or left wondering what was happening. That kind of communication and ownership made all the difference. What stood out most was how much care he put into the details. Everything was done thoughtfully and with intention. If something needed adjustment, he handled it right away. The finished ADU honestly came out better than we expected. The space feels comfortable, well-designed, and solidly built. It's clear he takes real pride in his work and wants the final result to truly reflect that. Working with Avo felt organized, professional, and stress-free. We would 100% work with them again.

We hired Ron to do the architectural plans for the remodel of a fourplex. He came in with a fancy camera scanner to measure everything, a very efficient process. He was very much on time with the delivery of the initial draft. We discussed minor changes and submitted to the city, and they had just had a few minor corrections before approval, which is better than other architectural teams I have worked with. After we began work on the project, we discovered a beam in the ceiling was not pointing in the right direction, leading to the need for a revision to the plans. The engineer Margarito went on site and approved changes, which allowed us to quickly adapt.

The timeline was totally reasonable (honestly, my slow email responses probably added more time than anything on their end), and the plans were approved by the city on the first try, which was a huge relief. It was also hard to find someone willing to take on a smaller project at a fair price, and they were very thorough. Even months later, they've still been responsive with follow-up questions from our contractor. Would definitely recommend, especially for smaller renovations or additions.
