"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"Trig Builders is an excellent one-stop shop for mainly excellent design, great help in selecting final materials/accessories and mainly for any complete home remodeling. Our master bathroom and kitchen needed to be completely demolished and redesigned. Yossi met with us several times and by listening to us and to what we want to get, he was able to come up with a new concept that included all the ideas and goals of what we wanted to have and his design was very clean, modern while still be within our budget. Yossi also managed and handled all the orders and purchased of the materials and final accessories which caused us to write this review because this was an excellent service. The bathroom was gutted and after the demolition, Yossi and his guys discovered that the floor support beams were damaged so we had to replace them with new ones and to have the floor leveled before they could start the new construction. This problem caused the budget increased by a small cost (Yossi charged us only for the materials) for the overall budget. All the professional people that were involved in the work including the plumber, drywall man, electrician and tile man were excellent and skilled people that executed their part in a very high level of work results. They were very careful about all the cleaning aspect by dropping cloths, plastic wraps for the floors. The kitchen was completely redesigned and Yossi was able to include everything we wanted and needed. He went with us prior to the work and helped us purchasing all the materials appliances. The remodeling job was a week behind the original schedule because of the floor problem and due to few days when we had to leave the house for personal reasons on top of complications in getting the necessary inspections completed. We must mention here that any of the delays was not caused because of Trig Builders fault. We are very happy and satisfied with Yossi, the workers and all the skilled people and mainly Trig Builders as the company and we highly recommend them."

"I recently completed my home remodeling project with HIC Builders, and my overall experience has exceeded my expectations. Avi, in particular, showcased extensive knowledge and was an absolute delight to collaborate with throughout the process. The team excelled in providing precise estimates for both budget and timeline. Despite minor setbacks due to city-related delays, they made sincere efforts to compensate for lost time. Having undertaken multiple projects in the past, I can confidently state that this has been the most gratifying working relationship I've had with a contractor. Without a doubt, I plan to engage HIC Builders again for my future projects."

"I was totally wrong in thinking that this company would do a good job because in reality they did something spectacular, the entire work team was very kind and attentive to our family, we are a family that does not open the door to anyone but we decided to trust American Professional Builders, Jose was very friendly and understanding with all of our needs, he always tried to adapt the work to each one's style, my children's rooms are comfortable, elegant and at the same time they can play and have fun with the design that Jose created especially for them, our yards are safe for the children and at the same time we can enjoy a weekend with the wonderful Deck with fireplace and kitchen, the pool with games that Jose recommended and that he built is beautiful and fun for the family, the type of tile he used looks luxurious and the pavers he installed with the artificial grass around it were exactly what we dreamed of, we are going to build an ADU soon and we are already working on the pl"

If you need a contractor, please save yourself time and grief, Ouri’s « Universal Home Design » is the dream company to work with. I am not kidding. Ouri and his team are the most pleasant, competent, responsive, on time, budget conscious people I have ever worked with. The work is flawless and the result is there to prove it.

"Golan Remodeling just finished a bathroom remodel for us, and we?re beyond impressed.The project manager was fantastic. He walked us through every step and made sure we were happy with the progress. The tile work and fixtures they installed are beautiful, and the whole bathroom feels like a spa now. The team was professional, clean, and respectful of our home. They are the best in Los Angeles. I?d give them 10 stars if I could!"

"When we think of family we think of the family members who have our back. They are willing to go that extra mile to make sure all is taken care of and weâ re happy. Such is the case with ADAR Builders. The extended family that makes sure your building dreams come true. A father, and two sons take charge as you add to or remodel your home. No job is too small or too large. They take their time in getting the details right so thereâ s no downtime later. The ADAR family cares for their customers and it shows. Problems that occur during the job are taken care of quickly and professionally. Not that there are a lot of problems during construction, but when there is concern, ADAR Builders is right there. When you hire a construction company youâ re looking for a partner that can guide you through the building process. ADAR Builders works with the client, listens to their concerns and suggests ways that their goals can be accomplished. From design to the final walkthrough ADAR Builders is there, every step of the way, guiding the client so their vision is realized. We met with many construction companies before deciding on ADAR Builders. I guess what sealed the deal for us, was that we knew we were dealing with family and whatever happens, we were in good hands. Amit, our project director, listened to our ideas and and gave us suggestions on how to implement them. We saw Amit many times during that initial phase, always refining and making sure that our plans were clear and concise. Talking about a project and then seeing 3 dimensional plans brings your project to life. Looking at our planned addition, with our actual furniture, gave us a realistic view of what could be accomplished. As we listened to Amit we knew that we were in good hands, and our project would be successful, brought in on time and budget. As you decide on what construction company will handle your project, donâ t be afraid to ask questions. Ask how long will it take to complete the project. Finally, lock down a price so there are no surprises at the end. Remember to be flexible when it comes to the timeframe, things happen (rain delays, illness building supplies out of stock). Also be aware that you will probably make changes to your plan, adding and subtracting items. This will affect the timeline and even the cost. Thank you ADAR Builders for working with us, and for us, to create our vision and bring it to life. Bob Sachs Karen Sachs"

"Fantastic. Not only is the end result superb but the process was as smooth and efficient as it could possibly have been. Gino consults you on everything, even after you’ve made the initial choice of cabinets, tile, countertop, scope of work, etc. He talks to you every day to update you. He has people working continuously, all organized so that no time is wasted. Once he started there was not a (week)day when his people weren’t working on my job, usually all day long. He has the work and teams organized and timed so that each one comes to your project as few days as possible, which reduces the cost. Gino is a stickler for detail, and getting everything exactly right, aesthetically and functionally, and the people he hires are very highly skilled with the same attitude. They’re also very clean. They sealed off the kitchen during the demolition so that the dust wouldn’t get to the rest of my open-plan condo. In construction they minimized particulate matter by doing all of the heavy cutting off-site. And they vacuumed the space every day before leaving! I’ve had contractors in several different cities and states and none came even close to this level of work, but it’s how remodeling should be! The price of my project was reasonable given the very high quality of the work, and the scope of work. Gino is very straight with you. The only costs that exceeded the estimate were due to my decisions to upgrade materials, or add a job to the project, and discovery of conditions in the existing structure that had to be upgraded (e.g., electrical). I’ve never been able to recommended a contractor before -- all the ones I’ve had have been so bad -- but I recommend Imperial Remodeling with two thumbs up."

"I had a problem in my home where one bathroom was not enough for my family, and the extra space we had was poorly arranged and unused. I contacted American Home Improvement to add an additional bathroom and fix the layout issue. Their team explained the process clearly and helped plan everything in a simple way. They handled plumbing, flooring, and fixtures without delays and kept the work area neat and clean every day. The crew stayed friendly and respectful, which made the whole process stress free. The new bathroom works perfectly and solved our daily problem completely. I am satisfied with the outcome and I highly recommend American Home Improvement for anyone planning an additional bath project."

FAQs for addition to existing structure building service projects in Stevenson Ranch, 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.
