Common Questions
Frequently Asked Questions
Can every NYC basement become a legal bedroom?
No. Egress window/door size, ceiling height, and light/ventilation rules decide. We design for the use that is actually approvable — recreation and home office are common legal paths when bedrooms are not.
Waterproofing first or finishes first?
Waterproofing and drainage always first. Finishing over active moisture is the most common failure mode we see in quote requests.
How long does a typical finished basement take?
Rough range after moisture plan approved: 4–10 weeks depending on bath/kitchenette and permit path. Weather and DOB queues can extend.
Will upstairs apartments smell or get dust?
We use sealed dust barriers and negative air when needed; plumbing tie-ins still cause brief interruptions we schedule with occupants.
Do you handle DOB filings?
We coordinate scope for filings and work with the owner’s expediter/architect when required. Exact filing party is named in the proposal — .
What drives price most?
Water control method, ceiling height solutions, bath/plumbing runs, and whether structural beams are needed — not just square footage of LVP.
