"Excellent! Dave took care of a number of repairs, communicated very well, had to purchase some items to do the repairs, was honest about his time and billing, and researched some future projects which I plan to hire him for. I am so grateful I found him through Angi!"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"I reached out to DB Construction needing my ceiling repaired and repainted due to a leak in my condo. David and Daniel were extermely easy to reach, prompt, and professional. The scope of work was clear from the beginning to end. Their quality of work was superb as well. They were receptive to my needs, which is greatly appreciated considering that this is a smaller scale job. I also appreciate their awareness and courtesy while working in my condo; they were conscious of the noise that was created and even made sure to clean any common areas where they tracked. Thanks so much! You have a customer for life. :)"

"I canâ t recommended Petra enough. As a first time home owner, dealing with renovations for the first time is stressful. Petra made it a smooth, transparent and even a fun process. Everything from design, ideation, cost considerations to execution was professionally and personally managed. The workers themselves were very polite and professional and also left everything clean â like newâ when they left. Overall our bathroom remodel was successful and I will definitely hire them again."

"I can’t say enough good things about Jake and his construction company. He recently completed an addition on our home, and the entire experience was outstanding from start to finish. Jake was professional, dependable, knowledgeable, and took a lot of pride in his work. He kept us informed throughout the project, paid attention to the details, and made sure everything was done right instead of cutting corners. The quality of the finished addition exceeded our expectations and looks like it was always meant to be part of the house. It’s hard to find a contractor you can truly trust, but Jake is one of them. He showed up, followed through on what he promised, and treated our home with respect. We couldn’t be happier with how everything turned out. I would recommend Jake and his company without hesitation to anyone looking for quality construction work. Five stars all the way — we would absolutely hire him again!"

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