Home Improvement Costs in St. Louis (2026)
St. Louis runs about 12% below the national average for home renovation costs, offering excellent value in a metro with one of the most interesting architectural housing stocks in the Midwest. The city's famous brick construction - most pre-1960 St. Louis homes are solid brick - requires specialized masonry expertise that is well-represented in the local contractor market. Washington University and a growing healthcare and biotech sector have supported steady renovation demand without major cost inflation.

What to Know About the St. Louis Market
St. Louis's signature brick construction is both an asset and a consideration in renovation planning. The brick itself is remarkably durable - homes built in the 1890s often have structural brick walls that outperform modern frame construction. But aging mortar, deteriorating lintels above windows and doors, and tuck-pointing needs are common maintenance issues. Hiring a mason who understands historic lime-based mortar (rather than using modern Portland cement mortar that can actually damage historic brick) is important for older homes. Repointing a single-family home's exterior runs $3,000-$8,000 depending on scale.
St. Louis's older neighborhoods - Soulard, Lafayette Square, The Hill, Webster Groves - have tight streetscapes with attached row houses and close-set single family homes. This affects renovation logistics: equipment access is limited, material staging requires permits in some neighborhoods, and neighbor relations matter. The city has active historic preservation overlay districts in several neighborhoods that add an approval layer to exterior changes. City of St. Louis permit processing runs 2-3 weeks for standard residential permits; St. Louis County municipalities vary.
Tornadoes and severe thunderstorms are a genuine consideration for St. Louis renovation planning. Impact-resistant roofing materials, reinforced garage doors, and sump pumps with battery backup are standard recommendations. The Mississippi River's proximity and Missouri clay soil create periodic flooding and basement moisture challenges. Many older St. Louis homes have the original clay tile sewer laterals, which are prone to root intrusion and failure - a sewer scope inspection before purchasing or doing major renovations is strongly recommended.
