"Started out well. Job started earlier than originally planned which was fine. Paid a third down to start job with understanding that rest would be paid in full upon completion. Everything was going fine until near the end of the job. After shower fixtures were installed I noticed they were the wrong finish from what we agreed on for the estimate. Took a week for Joel to reorder & replace. When the frameless glass shower panel was going in, the installer realized it was the wrong size, and had to be redone. The grout on the stone shower floor was very sloppily applied. Bits of dried grit are stuck on the stones. Before job was finished Joel was asking for full payment as he was running tight of money. I insisted on paying him in full only when job was complete. He wasn't very happy. Overall, the tile shower walls & bathroom floor tile look great. I only wish there had been more attention paid to the other details."

Second story addition building services FAQs

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.
