"Great! Excellent communication from the project manager, work crew went out of their way to do a great job and to pick up materials for me when delivery wasn't possible. They were punctual, cleaned up at the end of each day, tried to minimize the intrusion as much possible, and were really nice guys, great to work with. Work was done on time and on budget. Kitchen looks great and I couldn't be happier. The price was for labor and raw materials. We supplied the cabinets, lighting, countertops, sink, appliances, and windows. We also decided to get the attic insulated at the same time at their suggestion- that addition was not included in the cost below (I don't remember how much it was but it was reasonable.) Here's what the work included: Demo existing kitchen including walls, floor, ceiling and windows. New electrical sub panel and wiring in kitchen Gas line added to kitchen (gas was already in the basement area) Installation of new walls, floors, ceiling, windows, doors, trim Installation of cabinets, countertops, appliances, sink Painting Attic insulation (additional)"

Josh?s dedication and communication was crucial in ensuring the job was done quickly and professionally. He was is always available and provided quick response! We decided to do a bathroom remodel a couple of weeks ago. The entire process was done properly and as described to me at the start. Project was on schedule and went extremely smooth. The workers and staff were really professional, polite and easy to work with. I highly recommended BE Home Remodeling and specifically Josh Zack."

"After meeting with around 10 contractors, I decided to go with EA Homebuilders. Eric seemed honest and willing to do our remodeling the way we wanted it done. Great decision. Eric, Hector and crew were courteous and finished the job in the time they said it would be done, less than a month. We love our new bath/ shower. Highly recommend and would use again."

"We hired Bear Remodeling to convert our garage into an ADU for my mom to live in, and they knocked it out of the park! They handled everything. The team added proper insulation, installed new windows for natural light, and created a small but efficient kitchen area. They even finished the exterior paint to match our house perfectly. The transformation is incredible. You'd never know it used to be a garage. It took about 8 weeks from start to finish, which was actually faster than we expected. If you need more living space but don't want to move, I'd recommend their garage conversion service without hesitation."

"We received quotes from 3 different contractors. We chose GAXL because it's close to Newark and I like how Jose explains everything in detail. Originally we thought the remodeling would take 4 weeks but it took close 6 weeks. The whole project was great, the craftsmanship was superb. At one point, we found some tiles that are not very nice (from the manufacturer) and we asked them to redo the bathroom wall. They don't complain and understand our request. The workers are great, especially Marvin and this other guy (forgot his name). They WORK very very hard from 8a to 6p everyday. Jose is on time and is very prompt in returning calls or text. In fact he's the only contractor who's very prompt and I like that! On one of the walls they discovered a mold due to rain leaking and they're able to fix it in 4 days which is great. Jose and his son pickup the materials from the suppliers and drop them in our house. Overall, Jose and his men are courteous. I will definitely use GAXL for future remodeling."

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