Our process,
step by step
Assessment and moisture check
We evaluate ceiling height, moisture, existing mechanicals, and egress so the plan starts on a dry, code-ready foundation.
Design and layout
We design the lower level around how you will use it and confirm a written scope and allowances before construction.
Permitting and construction
We file permits and manage framing, mechanicals, and finishes with weekly written updates.
Inspections and walkthrough
Final inspections are coordinated and we walk every detail with you before handoff.
Typical timeline
Most basement remodels run 6 to 12 weeks after permits, depending on square footage, egress work, and whether a bathroom or kitchenette is included.
Basement finishing cost in the Treasure Valley
As of 2026, finishing a basement in the Boise area commonly plans $40,000 to $100,000 or more. Open family rooms sit at the lower end; egress windows, a full bathroom, a kitchenette, or a bedroom suite reach the upper end.
These are planning ranges, not bids. Egress work, plumbing access, and moisture or radon mitigation drive basement budgets, which we confirm in a written scope after your free in-home visit.

Why design-build for your basement remodeling
As a design-build remodeler, we bring design, estimating, permitting, and construction under one contract and one accountable team. That removes the handoffs and finger-pointing that happen when a separate designer and general contractor are involved - and it keeps your basement remodeling on a single, coordinated schedule.
You get a written scope before construction begins, clear allowances for selections, proactive communication throughout the build, and a workmanship guarantee when the project is complete.
