Finished properly, from the slab up
In our climate, a basement conversion succeeds or fails on moisture control. That is where we start every time.
- Moisture control and waterproofing
- Code-compliant egress windows
- Insulation and vapor barriers
- Framing, drywall and finish carpentry
- Electrical, lighting and HVAC extension
- Full bathrooms and kitchenettes
- Sound isolation between floors
- Durable, moisture-tolerant flooring
Typical timeline: 6–14 weeks
