"When I found IND Construction and decided to move forward with them, I felt at ease. Every single step, from design to architecture to clearing out an old shed, to building the structure and final touches, was done with care. That meant a lot to me and my dad, especially now, with COVID-19. The workers were thoughtful and all my questions were answered and attended to. At the end of the day, I was really thankful that my guesthouse was built. It gave me a sense of relief and accomplishment. When I look at it, I think of my mom, who had wanted to build a guesthouse. I think she would have been really happy."

"H&A MY Design made building our garage an effortless and enjoyable process! From the moment we walked into their incredible 5,000-square-foot showroom, we knew we were in the right hands. The showroom truly is a one-stop shop where we could explore construction materials, finishes, and design ideas all in one place. The team helped us narrow down options that fit both our vision and budget. Their professionalism, attention to detail, and seamless communication were second to none. The construction crew was respectful and clean, completing the job on time without any hassle. I wouldn’t hesitate to recommend them for any home improvement project."

"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.

"I hired Unique Home Design to build an addition, big and not easy project but Steve and his team made it pretty simple. They were well organized, professional, efficient and helpful. Steve was very communicative and always ready to answer all my questions, listened my requests and gave me his valuable advises. The project was finished ahead of schedule and with no unexpected extra costs. I am super satisfied with result and high quality work, thanks for everything. Highly recommended contractor!"

"I am very pleased with the work done by Hic builders. Our initial contact was Josef. He came out and gave us a fair price to replace a wood fence, patio cover, and deck. Materials were sourced and brought in without delay despite supply shortages. My dad is a civil engineer and he noted the wood to be of good quality. He and his workers showed up daily, on-time until the project was completed. Every day the work area was left tidy and cleaned up. We live in a townhome. The only access to the backyard is through the front door and living area. His team covered our furniture and flooring. We will definitely call on Hic Builders in the future and recommend others to do the same."

"If you are looking for an honest contractor that does great work, look no further than ING Construction. We hired them to build a recreation room onto our detached garage, which came out amazing. 4 years later, we had them come back and turn that rec room and part of the garage into a legal ADU (Accessory Dwelling Unit). 3 of our neighbors have now used ING Construction for their projects. I do not think that you can find a better recommendation than that."

"It's not easy to find a contractor these days, especially one that you can trust We hired KN Remodeling to do an addition to our home. After a long research, we decided to go with KN Remodeling. Nathan was very honest and professional, and their price was very fair... from the first meeting we knew what we are going to get... QUALITY! Throughout the all project, Nathan was involved in every step that was made, he was always a call away and I never felt like I need to chase someone to get answers. Their team was always on time, very professional, clean and did the job in a timely manner (like promised) and on the best side! I really don t have anything bad to say about KN Remodeling. I also referred some of my friends to them because they deserve it! We are very happy with our Home Addition; the final outcome is just beautiful! We highly recommend KN REMODELING AND NATHAN , very professional and quality work thank you again!"

FAQs for addition to existing structure building service projects in Simi Valley, 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.
