Frequently Asked Questions

What qualifies as “light” commercial construction?
Answer:
Projects that don’t require full-scale GC management — like retail fit-outs, small business units, and plumbing-intensive additions. If it involves pipes and planning, we can likely help.
Can you handle framing or drywall too?
Answer:
No — we focus strictly on plumbing. For any framing or drywall work, we’re happy to refer you to one of our trusted partner contractors.
Are permits required for commercial plumbing?
Answer:
Yes. We’ll help submit the necessary permits and arrange for inspections through local building departments.
What’s your availability for new projects?
Answer:
We typically book 1–3 weeks out, depending on project size. Emergency work and member clients are prioritized when needed.
