"The KN Remodeling team did an excellent job at our home completely remodeling 3 bathrooms, painting our entire home and rebuilding a huge planter outside. We trusted them in our home while we are out of town almost the entire time. We hired them back to do additional work in our home that they did quickly and expertly. The team was professional, very friendly, worked quickly, quietly, cleanly, and I would highly recommend them."

"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 recommend MF Construction without hesitation for any and all of your home remodeling needs. Mike and his team did a beautiful job! They exceeded our expectations in performance, outcome, attention to detail, and timeline. From the start of the project to the finish, the team showed up every single day, even on some weekends. They stayed late when necessary to keep the project on track and worked tirelessly to ensure our satisfaction. Mike, Melvin, and the team are exceptionally clear communicators. I always knew what was going to happen next with the project. They checked on the team's progress and my satisfaction frequently. Mike was kind and patient with both of my elementary-aged children. Their bedrooms got a complete redesign and overhaul and he treated them just like customers, giving them input and ownership into the process. Thank you so much, MF construction! We could not be happier with our "new" home!"

"My wood balcony has termites and water damages. So I hired RET to do the job. Kevin gave estimates and recommended composite planks for floor and red woods for railings. His workmanship was very professional and finished on time! On top of that, Kevin updated my balcony to the latest building codes. His price is very reasonable. If you want cheap prices and lousy jobs,hire someone else! Highly recommended!"

"Skyline converted our attached garage into a beautiful ADU with quality workmanship, fair pricing, and top notch materials. They were very particular with respect to details, which made a huge difference in the end. I would strongly recommend skyline and will use no other company for any project, large or small. If you want the job done right, with transparency and professional service from start to finish, look no further!"

"Satisfied customers reporting! We're writing this review four months after the completion of our bathroom renovation. We've been thrilled with the final product and the experience of signing with Ouri from day one was a pleasure. This was our first large project and we would undoubtedly hire Ouri again. Project We instinctively knew Ouri was the best fit for us after the on-site consultation. Not only are his reviews overwhelmingly positive, but he's knowledgeable, respectful, patient, and honest, with competitive pricing to boot. He's also a very responsive communicator. We needed some time after signing the contract to shop for materials. Ouri kindly rolled with our uncertain timeline, checking in periodically without any pressure to see where we were at and advising on any questions we had along the way. From the beginning of the project, his crew was respectful, clean, and always checked in with us as any questions came up. The project went smoothly and for one very minor hiccup that came up, Ouri & crew were quick to address without question. And months later, he sent a member of his crew to come troubleshoot something minor, again without any hesitation. It's challenging to keep these brief when you have such a great experience, especially when you read and hear about horror stories from other people. Selfishly, maybe we should keep this to ourselves so he isn't so busy when we need him for another project in the future :) Scope The bathroom was totally gutted save for some sections of drywall. A full tiled shower with a bench was installed (replacing a tiny old corner unit!), along with added lighting & exhaust fan, new floor tile, and all new fixtures/ cabinets/ paint. The plumbing and the shower drain were relocated. An old window was removed and replaced by a new one on an adjacent wall."

"I could not recommend Ben Oded and his team more. I've now worked with Ben on multiple projects, including a new bathroom, renovations of existing bathrooms, electrical, plumbing, and most recently, an ADU, and on every occasion, Ben and his team have delivered. Ben is honest, reliable, and direct. When he says he is going to do something, I never have to worry about it getting done. He'll also be very honest with you about what's possible and at what price. There are also numerous examples of Ben going above and beyond. One such example was around my wedding. The week before the wedding, we lost all hot water...We had multiple plumbers over, but no one could find the solve. Two days before the wedding, we were scrambling. I called Ben, and within an hour, we had a plumber over, who fixed the issue and at a fraction of the cost. I could not recommend Ben more. Call him for your home or investment property renovation needs..you won't regret it!"

FAQs for addition to existing structure building service projects in San Marino, 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.
