Window & door replacement in Mid-Cambridge
Mid-Cambridge is Cambridge's late-19th-century 2-family + 3-family (1880-1915) submarket. The Mid-Cambridge Neighborhood Conservation District (designated 1986) is one of three NCDs in Cambridge — alongside Avon Hill and Half-Crown-Marsh — and the substantive review intensity inside Mid-Cambridge is equivalent to the Boston Landmarks Commission, with the Cambridge Historical Commission rejecting window-mullion patterns and roof-line modifications that depart from the 1880-1915 reference period.

Because Mid-Cambridge's housing stock concentrates 2-family and 3-family wood-frame multifamily, kitchen renovations frequently engage 780 CMR §722 fire-rating retrofits between stacked units — Cambridge ISD interprets these requirements more strictly than Boston ISD, often requiring full 1-hour rated assemblies even on minor scope.
Mid-Cambridge's Trowbridge Street and Wendell Street single-family pockets carry some of the most expensive per-square-foot kitchen renovation costs in metropolitan Boston — the combination of 2x10 floor joists at 16-inch on-center, lime-mortar masonry foundations, and Cambridge Historical Commission review pushes mid-complexity kitchens toward the $250K-$450K range.

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.
