"I was drawn to Amber's Home Remodeling because of their unique design aesthetic. They incorporated subtle Filipino touches into my kitchen room remodel that I absolutely love. The free 3D design process was amazing-it helped me visualize everything perfectly. And the care they took with every detail was truly impressive "

Here at Embee & Associates, Inc., we pride ourselves in a job well done. With an eye for detail, we will help your dreams become realities so please contact us today for a fast and friendly service that you will not be disappointed in!!

"Overall my experience with this company was great! The work that was done was really really good! Our contractor who assisted us was Jose. We added a living space and master bedroom to our home. The additions done look as if they were part of my house this whole time. Honestly it looks way better than I expected. The only reason I rated the company a 4.5 was because there was always some kind of miscommunication between our contractor and his workers. Don t get me wrong, things were always resolved, Jose was great at that. But my recommendation to is to make sure communication is #1. That way the customer is not confused or left wondering what will happen next. There was an issue with his floor guy though, he was rude and unprofessional. BUT the reason I am mentioning this is not to put down the company but let you know that we expressed concern for this issue and it was resolved professionally by Jose and it never became an issue again. The quality of work was top notch! His workers were all pretty cool guys and we always felt comfortable of who was coming into our home to do the work. I highly recommend this company for your next big project😊👍🏼"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
