Material choice determines both cost and maintenance commitmentVinyl siding is the most popular option in St. Louis — low maintenance, moisture-resistant, and costs $4,400–$6,330. Fibre cement (James Hardie) costs $5,275–$9,495 and is highly durable with a 30-year warranty — the premium choice for St. Louis's varies by season. Engineered wood costs $4,220–$8,440 and looks more natural. Wood and cedar shake are premium options at $8,440–$19,350+ requiring periodic painting or staining.
Removal of existing siding affects cost and reveals surprisesRemoving existing siding adds $1,500–$4,000 depending on material and home size — and often reveals problems: rotted sheathing, inadequate house wrap, missing insulation board, or moisture damage. In St. Louis, these discoveries are common and budget overruns are typical. Ask your contractor how they handle discoveries mid-project and whether there's an allowance for substrate repairs in their quote.
House wrap and moisture barrier are non-negotiableNew siding must be installed over a continuous, properly lapped moisture barrier (house wrap or felt paper). Skipping or improperly installing house wrap is the most common cause of moisture damage behind new siding — leading to mould, rot, and interior wall damage years later. In St. Louis, where varies by season, this step is critical. Ask your contractor what brand and specification of house wrap is included in their quote.
Trim, soffit, and fascia are often a separate costMany siding quotes cover wall panels only — trim boards, corner posts, J-channel, soffit, and fascia are quoted separately or discovered to need replacement when the old siding comes off. A complete siding replacement typically includes replacing these elements too. Get clarity upfront about exactly what's included: siding panels, trim, soffit, fascia, window and door surrounds. Hidden omissions are the most common source of siding cost overruns in St. Louis.
Fibre cement requires specific installation knowledgeFibre cement (Hardie) is an excellent product but requires factory-trained installers to maintain the warranty. Hardie's 30-year warranty is voided by improper installation, including incorrect paint, missing caulk, or improper clearance from grade. Confirm that any fibre cement installer holds HardieZone certification — this is a genuine quality differentiator, not just a marketing point.
Lead paint risk in older St. Louis homesHomes built before 1978 may have lead paint under the existing siding layers. Federal EPA RRP rules require certified contractors to follow lead-safe removal procedures — this adds cost but is legally required. Confirm your contractor holds EPA RRP certification if your home predates 1978. Non-compliant removal exposes you to EPA fines, health risk, and liability for any occupants or neighbours.

How much does siding replacement cost in St. Louis?
Siding replacement in St. Louis costs $10,550 on average, ranging from $4,400 for basic vinyl on a small home to $19,350 for fibre cement or premium materials on a larger home. St. Louis's COL index of 88 puts local installation labour 12% below the national average. Material choice (vinyl vs fibre cement vs wood), home size, removal of existing siding, and whether substrate repairs are needed are the main cost drivers.
What's the best siding material for St. Louis's climate?
In St. Louis's climate (seasonal factors affect pricing), fibre cement (James Hardie) is widely considered the best combination of durability, weather resistance, and aesthetics — it's resistant to moisture, insects, and fire, and carries a 30-year warranty. Vinyl siding is a practical lower-cost option but can warp in extreme heat and fade in high-UV environments. Wood siding looks premium but requires painting every 5–7 years in St. Louis's conditions. Match material to your maintenance tolerance and budget.
How long does siding replacement take in St. Louis?
A full siding replacement on an average St. Louis home (1,500–2,500 sq ft of exterior) takes 4–10 days for a crew of 2–3. Larger homes or those with complex trim, multiple gable ends, or fibre cement (slower to cut and install than vinyl) take longer. If the project involves removing old siding and discovering substrate repairs, add 2–5 days. Get a written schedule from your contractor and confirm when substrate inspection happens in the sequence.
Does new siding increase home value in St. Louis?
Siding replacement consistently ranks among the highest-ROI home improvements in St. Louis, typically returning 70–80% of project cost at resale according to Remodeling Magazine's Cost vs. Value data. The ROI is highest when replacing visibly worn, dated, or damaged siding — buyers discount homes with obvious exterior maintenance needs. New siding also improves energy efficiency (especially when combined with house wrap upgrade) and reduces future maintenance costs.
Do I need a permit for siding replacement in St. Louis?
Siding replacement that involves only like-for-like material (replacing vinyl with vinyl, same profile) typically doesn't require a permit in most St. Louis jurisdictions. However, if you're changing the home's exterior cladding type, adding insulation board under the siding, or if your home has known lead paint (pre-1978), a permit and EPA compliance may be required. When in doubt, ask your contractor and check with St. Louis's building department — the answer takes 5 minutes and prevents future headaches.
