Frequently asked questions
Do NYC co-ops allow tile in kitchens? Most do, provided the STC assembly meets the Alteration Agreement's sound-rating clause. Some pre-war co-ops still prefer hardwood for common-corridor aesthetics.
Can I add heated floors to my NYC bathroom? Yes — Schluter Ditra-Heat, WarmlyYours, or Warmup mat systems. Requires dedicated circuit and a GFCI. Triggers electrical permitting if exceeding panel capacity.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
