"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

FAQs for second story addition building service projects in Los Angeles, CA
Converting a vaulted ceiling into a second floor requires three to six months from planning to completion. The process begins with several weeks of design and engineering, followed by permit applications, which vary in processing time by location.
Construction itself spans several months, including framing, systems installation, and finishing work. Weather conditions, contractor availability, and inspection schedules can all influence your project timeline.
Several factors could make your conversion challenging or impossible. Inadequate roof support structures, insufficient foundation capacity, or problematic truss configurations might require prohibitively expensive modifications.
Some homes lack the minimum ceiling height (12 feet at the lowest point) needed for functional second-floor spaces. Building code restrictions in your area might also limit conversion possibilities, particularly in historic districts or homes with specific architectural designations.
Begin with professional assessments from both an architect and a structural engineer who will evaluate your home's specific characteristics. They'll examine existing framing, measure available headroom, assess load-bearing capacity, and identify potential obstacles like HVAC ducts or plumbing vents.
These experts will also review local building codes to determine feasibility. Their preliminary analysis provides crucial information about structural requirements and potential limitations before you commit to the project.
Whether you'll need temporary housing depends on several factors, including the project's scope and your tolerance for construction disruption. Major structural work creates significant noise, dust, and potential utility interruptions that many families find challenging to live with. Safety concerns may also arise during certain construction phases.
Some homeowners successfully remain by isolating the construction zone and establishing clear work schedules. Discuss living arrangements with your contractor early in the planning process to make informed decisions.
