"Jakubek did a great job on our basement remodel. David, Robert, Aric, and Tom showed up everyday on time, and were very polite, very quick, and very clean. They put down floor protection when they moved materials in and out of the house. At the start of each day they would explain what they were doing and at the end of the day we could walk through to check on progress and next steps. All of our requests were accommodated, and David was very responsive and flexible with change orders and a last minute decision that we made. Overall, the basement turned out great. It adds 50% more space to our house and provides a warm/clean place for the kids to play. If I could go back in time I'd hire David and Jakubek sooner."

FAQs for second story addition building service projects in Crystal Lake, IL

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.
