We started LEVEL because, after years in the building industry (Civil, Structural, Home Building, etc) we continued to see something missing in our industry that cost homeowners untold stress and frustration, contractors lost time and money and realtors and lenders left unable to satisfy their client's needs. We decided to do something about it, and then - LEVEL Engineering was founded. We serve your interests and provide knowledgeable, expert inspection, analysis, recommendation, and reporting. So whether your need is for permitting, forensics, foundation problems, new or repair engineering designs; or just for your peace of mind - let us help you navigate your structural engineering projects."

Now, our bathroom feels like a spa every time we step in. I appreciate the quality and attention to detail. These folks definitely know what they?re doing!"

"We had several contractors give us estimates and Ani of LGC was the best. She was knowledgeable, professional and not pushy at all. My husband and I felt very comfortable with her and it didnâ t take us long to choose her. She helped with the design, locating materials and also helped us save money. The workers arrived on time, put in a full dayâ s work and did an amazing job for us. What started as a primary bathroom remodel turned into primary bedroom, bathroom and master closet redo, flooring to most of our house and two patio redos. We felt comfortable with the entire process from start to finish. Ani and her crew kept us informed and helped with giving us other options that we didnâ t even think of. In a few weeks they will put in a beam in our family room. Iâ m very excited. The entire crew were very professional, knowledgeable, neat and cleaned up afterwards. We will definitely use them again. We couldnâ t be more happier with the choice we made. It was the RIGHT one."

"I wanted to replace carpet with wood-look vinyl in living room, dining room, library and office in my house, but the floors were very uneven. One company said they would only recommend replacing with new carpet and a second company gave me a ridiculously high estimate for the work. Jacobs Construction quoted a fair price, which went up a bit when they pulled up the carpet and saw just how bad the floors were. The final cost was far below the other quote. The work was done in just two days, and the floors are beautiful!"

"Jeromes extensive experience with business TI projects made him the perfect choice for our needs. Hiring him was one of the best decisions we could have made. His exceptional skill, combined with his genuine kindness and honesty, truly set him apart. Culver City presents its fair share of challenges, particularly with the citys responsiveness, but Jerome and his team went above and beyond. They consistently communicated with the city on our behalf, advocating tirelessly to expedite the permit process and relieve so much of the stress on our end. Jerome dedication and professionalism are unmatched, and his commitment to his clients is evident in every step of the process.
