Our work
FAQ
Costs vary by layout, finishes, and code requirements. Expect a broad range depending on necessary structural work, egress solutions, and mechanical upgrades. We provide a scoped estimate after an on-site walkthrough so you get line-item pricing for your project.
Typical projects take several weeks to a few months. Timelines depend on permit lead times, scope (bathroom/kitchen installs add time), and inspection schedules. We outline a projected schedule in the estimate.
Most disruption is confined to the basement but expect occasional access needs for HVAC, electrical, or plumbing lines. We protect adjoining areas, set work hours, and coordinate deliveries to minimize impact.
Request a site walkthrough and estimate. We review your goals on-site, note code or egress needs, then deliver a written proposal with options and a projected timeline.
