Frequently Asked Questions

Do attic renovations need permits?
Yes. Most attic renovations that create habitable space require permits, especially when structure, insulation, or exits are changed. We handle all drawings, engineering, and applications for you.
Can every attic be converted into a livable space?
Not always. Our feasibility review checks headroom, structure, access, and mechanicals. As experienced attic conversion contractors, we’ll advise if your attic can be safely and practically converted.
How long does an attic conversion take?
Timelines vary, but many attic conversions take several weeks to a few months, depending on size, complexity, and inspections. We provide a project schedule before work begins.
Do you handle structural reinforcement?
Yes. Our team coordinates engineering and reinforcement of joists, beams, and supports as part of your attic remodelling project.
Can you add skylights or additional windows?
Absolutely. Skylights and new windows are common in attic renovation projects and are designed to meet daylight, egress, and energy-efficiency requirements.
What is required for fire code compliance?
Fire separation, proper exits, and safe stairways are key. When we renovate attic spaces, we design and build to meet local fire and building codes and review these requirements with you in advance
