Chicago Deck + Patio — Pressure-Treated, Composite, Freeze-Thaw, CDOB Permit
Chicago deck reality. Pressure-treated southern yellow pine dominates, composite (Trex, TimberTech) for low-maintenance, freeze-thaw cycle kills untreated wood, CDOB Easy Permit for non-structural, Standard Plan for elevated or attached. $14K-$65K typical.
Chicago freeze-thaw cycles destroy untreated wood. Pressure-treated southern yellow pine is the baseline; composite (Trex, TimberTech) trades higher upfront cost for zero annual maintenance. Ground-level patios use concrete pavers or bluestone with sand set.
Frequently asked questions
Do I need a permit for a Chicago deck? Yes — any deck over 30" above grade requires CDOB permit. Ground-level patios over existing grade: typically non-permit.
Pressure-treated or composite in Chicago? Composite (Trex, TimberTech, Fiberon) for zero-maintenance and UV-stable color. Pressure-treated for lower cost + natural aesthetic but requires annual sealing.
How much does a Chicago deck cost? PT pine deck: $35-$60/sqft installed. Composite: $55-$95/sqft. Typical 300 sqft deck: $14K-$28K PT or $22K-$42K composite.

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.
