Real cost ranges for St Louis, MO, priced in USD. Every row is what homeowners actually spend across the scope spectrum — the low end is a pull-and-replace on the existing footprint, the high end is a full custom build with premium finishes.
Cabinets, counters, appliances, and plumbing/electrical updates drive the range. The top of the band reflects full layout changes and premium finishes; the bottom holds for pull-and-replace scopes on the existing footprint.
Tile, fixtures, and waterproofing are the big drivers. Primary and ensuite bathrooms with walk-in showers or freestanding tubs sit near the top of the band; hall baths come in closer to the bottom.
Detached units and garage conversions vary most by square footage, foundation type, and utility runs. Where local law does not recognize ADUs, this row maps to the nearest annex / granny-flat / laneway equivalent.
Whole-home scope covers all trades plus permitting, structural, MEP, and finishes. Historic properties, listed buildings, and seismic-retrofit markets sit well above the median.
Material choice (asphalt shingle, tile, standing-seam metal, membrane) dominates the range. Pitch, access, and city-specific wind/fire codes add the rest.
Framing, insulation, egress windows, and waterproofing move together. Adding a bathroom or full kitchen pushes the cost well above the base finish scope.
Prep work (siding repair, pressure wash, priming) is the hidden driver. Coastal and high-UV markets use specialty coatings that cost more but last longer.
Ask Baily about your St Louis renovation and you will not be passed around. St Louis is one of the most distinctive remodel markets in the United States because its housing stock is older than almost any other major metro in the country, its preservation districts are more numerous than most homeowners realise, and its limestone-foundation building tradition from the pre-1940 era asks questions of contractors that national lead-generation sites like Angi simply cannot vet. A Central West End four-square on a raised basement, a Soulard brick row house, a Lafayette Square Second-Empire mansion and a Chesterfield post-war ranch all need different specialisms, different permit pathways with the City of St Louis Building Division, and different relationships with the Cultural Resources Office. Baily holds that context and introduces one vetted St Louis builder who fits your property and your scope. No twelve quote-spray phone calls. No re-explaining your kitchen drawings to a new tradesperson every week. One professional, one relationship, one accountable name from permit through punch list.
