A full living level with a bathroom and smart storage is $45,000–$80,000, our most common basement project. Premium lower levels with a theater, guest suite or wet bar run $80,000–$150,000+. Itemized written estimate within 48 hours of the free visit.
Most basements take 5–8 weeks from first framing to final walkthrough, with a written schedule up front. The work zone is downstairs and sealed off, so daily life upstairs barely changes.
Moisture is handled before anything else: we test, seal and correct drainage issues before a single stud goes up. A finished basement is only as good as what's behind the drywall — that's the part we never rush.
We pull all permits and schedule the inspections. If you want a legal bedroom downstairs, code requires an egress window — we cut, frame and waterproof those ourselves as part of the project.
Yes — a full bathroom is part of most basement projects we build. We handle the plumbing rough-ins, ejector pit if needed, and ventilation, all to code and all by our own crew.
