"If I could give this company a 10, I would! I am a retired interior designer who has worked with many contractors. None have been as competent, professional, and considerate as Pristine Construction. Pristine was not the lowest bid, but I hired them because I knew I could work with them and liked the suggestions that Nathan suggested for the plans that I designed. It is hard to live with a team of strangers for several months and the overall construction itself is stressful because you have to empty the rooms and still try to have an organized life. But Pristine worked to make the disruption as minimal as possible. The workers arrived early, worked diligently, and cleaned thoroughly at the end of each day. They even worked the day after Thanksgiving. Love the result!"

"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.

"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."

I had very specific plans when it came to this room addition and new bathroom. They met and exceeded all of my expectations. If you’re planning any kind of construction in your home and you want a company that is respectful, skilled, and timely you should give them a call. My house has become my dream home. I'm really enjoying it!"

"Mike Mamen called back within the hour. Next day I showed him the problems with my 90-year-old garage's roof and wiring. He tell me that existing 2x4 rafters could be sistered rather than replaced with 2x12. Additional 2x6 tie beams across garage. He recommended all new shingles, garage door, side door, window, lights, and outlets. Exterior paint on stucco and wood trim. Mike recommended replacing the house 100A electric service panel with 200A, in addition to trenching a conduit between house and garage. He also recommended grading behind the garage to route water away from its foundation. Also, adding gutters and downspouts to both the garage and house. Later we discovered that the house's facia needed to be replaced. He drove me to two current job sites, introduced his crew, and showed the work being done. Mike is knowledgable, direct, friendly, and talkative. Listens to my concerns and ideas, then presents options and his recommendations. Responds to later questions and text messages. Knows local building codes and permitting process. Works by the book -- written contract proposals describe the job and materials. Flexible in handling changes and unexpected glitches. Does minor tasks gratis. Personally attends inspections. Likewise, foreman and electrician Luis is friendly and competent. I am pleased with the competence and results of MF Construction and Design. The entire job took about seven weeks. It was more expensive than I would have thought. OTOH I did not get other bids."

"Imperial Remodeling took on a top-to-bottom remodel of my small three-level townhome, including a roof-top deck. The home, which was previously occupied by a hoarder, was transformed! Gino Henn and his crew replaced everything, from the flooring in every room, to each of the 2.5 bathrooms and the leaky 2-stage roof. The roof is now an urban oasis, with turf and a deck cover. Imperial did a fantastic job. I love my totally new kitchen! Because the condo complex was old and not well maintained, there were unexpected and tricky problems with electrical and plumbing systems. But Imperial handled it all -- and stayed on schedule. The workmanship is excellent and detailed. The crew was careful and mindful of my neighbors and the cleanliness of building's common areas. Overall, I am very happy with the finished project."

"We recently hired a construction company to complete an addition on our home, and we couldn?t be happier with the results. From the very first consultation to the final walkthrough, their professionalism, transparency, and attention to detail truly stood out. The team took the time to understand our vision and offered thoughtful suggestions that improved both the design and functionality of the new space. Throughout the project, communication was clear and consistent. We always knew what phase we were in, what to expect next, and any questions we had were answered promptly. The quality of workmanship exceeded our expectations. The addition blends seamlessly with the original structure of our home?it looks and feels like it was always meant to be there. The crew was punctual, respectful of our property, and kept the worksite clean and organized each day. We highly recommend this company to anyone considering a home addition or renovation."

FAQs for addition to existing structure building service projects in Mount-wilson, 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.
