St. Louis Web Design
St. Louis businesses deserve a website that actually works.
St. Louis sits at the center of a deep Midwest economy — healthcare systems along the Central West End, logistics and manufacturing along the river, professional services downtown and in Clayton, and a dense corridor of HVAC, plumbing, and roofing contractors serving the metro and Metro East. Competition for local search is real, and most business websites in the market are still slow, thin on schema, and built like brochures.
If you're a St. Louis business competing for attention online, your website needs to do more than look polished — it needs to perform. That means fast load times, clean code, proper schema markup, and content built around how people actually search in St. Louis County, St. Charles County, and the Metro East.
FlintHorn is expanding into the St. Louis market. We work with St. Louis businesses that want design and SEO handled as one engagement — not three separate contracts. We build on a modern, performance-first stack, and every site ships with a 100 Lighthouse score and architecture built to rank.
Whether you're in Downtown, the Central West End, Clayton, Chesterfield, Kirkwood, or across the river in Belleville and Edwardsville — we build sites that rank locally and load fast for every visitor.

What makes FlintHorn different for St. Louis businesses.
The technical gap most St. Louis agencies can't close.
St. Louis has plenty of web shops — but many are still shipping bloated WordPress builds that score poorly on Lighthouse and take seconds to load. Your competitors are using the same playbook. We build on Astro, Sanity, and a performance-first stack that produces 100-score sites loading in under a second. That's a different category, not a marginal tweak.
Built for home services — and the rest of the metro.
We specialize in HVAC, plumbing, and roofing websites, and we work with adjacent St. Louis businesses that share the same lead-flow problems. Local search intent, call tracking, service-area pages, and conversion paths are part of the brief — not an afterthought.
Growing into St. Louis — intentionally.
We're adding St. Louis as a primary market we serve, with a physical presence on the roadmap. You get senior-level work now — remote-first collaboration with clear scope — and a partner investing in this market long term, without the overhead of a downtown office markup.

St. Louis web design questions, answered.
How much does web design cost in St. Louis?
Most St. Louis web design projects with FlintHorn range from $5,000 to $25,000 depending on scope, number of pages, and whether SEO and content strategy are included. We provide a detailed proposal after an initial consultation — no ballpark guesses or surprise invoices.
How long does it take to build a website for a St. Louis business?
Typical timelines are 4 to 8 weeks for a standard business website. Larger projects with custom functionality, content migration, or extensive SEO work may take 8 to 12 weeks. We'll give you a realistic timeline before starting — and we stick to it.
Do you work with St. Louis HVAC, plumbing, and roofing companies?
Yes. Home services is a core focus. We build contractor websites that capture high-intent local searches and pair cleanly with lead qualification. Start with our HVAC website design offering, or ask about plumbing and roofing in a consultation.
Are you based in St. Louis?
We're expanding into St. Louis as a primary market we serve, with a physical address planned. Engagements today are remote-first with clear scope and senior people on the work — the same model we use successfully across Wisconsin and the Twin Cities.
Can you migrate my existing St. Louis website without losing rankings?
Absolutely. We handle full migrations — including content mapping, redirect strategy, and post-launch monitoring. Whether you're on WordPress, Wix, Squarespace, or a custom platform, we'll move you without losing what you've already built. See our website migration process.
