Siding Replacement Cost in Myrtle Beach: 2026 Complete Breakdown

Siding replacement in Myrtle Beach costs $5,000 to $25,000 or more for a full house, depending on the material you choose, the size and complexity of your home, and whether the sheathing behind the old siding needs repair. That range covers everything from basic vinyl on a small ranch to premium fiber cement on a large two-story home with extensive trim work.

Here is the quick cost-per-square-foot breakdown by material for the Myrtle Beach market in 2026:

• Vinyl siding: $4 – $8/sq ft installed | 15-25 year lifespan
• James Hardie fiber cement: $8 – $14/sq ft installed | 30-50 year lifespan
• Engineered wood (LP SmartSide): $6 – $11/sq ft installed | 15-25 year lifespan
• Aluminum siding: $5 – $9/sq ft installed | 25-40 year lifespan
• Stucco: $6 – $10/sq ft installed | 20-50 year lifespan

Those per-square-foot numbers are just the starting point. Myrtle Beach is one of the harshest environments for siding on the entire East Coast. Salt air eats through cheap materials and fasteners. Humidity breeds mold behind walls. Hurricanes rip off siding that was never rated for the wind zone. And the UV exposure along the Grand Strand fades and degrades siding faster than anywhere inland. The material you choose and how it is installed determines whether your siding lasts 15 years or 50 years. This guide breaks down every cost factor so you can make the right decision for your home and your budget.

Siding Replacement Cost by Material

The material you choose is the single biggest cost variable. Each option has different material costs, labor requirements, and lifespans — and each performs differently in Myrtle Beach's coastal climate. Here is a detailed comparison for the local market in 2026:

Vinyl siding is the most common choice in the Myrtle Beach area purely because of upfront cost. Standard vinyl at $4 to $8 per square foot installed is roughly half the price of fiber cement. It comes in hundreds of colors and profiles, requires minimal maintenance beyond annual power washing, and most contractors can install it quickly. The downside in coastal SC: standard vinyl becomes brittle from UV exposure within 10 to 15 years, fades noticeably in direct sun, and can crack or blow off in sustained hurricane winds above 110 mph. If you go with vinyl in Myrtle Beach, choose insulated vinyl — the foam backing adds rigidity, wind resistance, and a small R-value improvement.

James Hardie fiber cement is the premium choice and the one we recommend most often for Myrtle Beach homes. It is made from Portland cement, sand, and cellulose fibers — a combination that does not rot, warp, burn, or attract termites. The HZ10 formulation used in our climate zone adds extra moisture resistance. It withstands 150 mph winds, carries a Class A fire rating, and lasts 30 to 50 years with minimal maintenance. The higher upfront cost is offset by the fact that you will likely never replace it again. For a detailed Hardie board cost analysis, see our Hardie board siding cost guide.

LP SmartSide engineered wood sits between vinyl and fiber cement in both cost and performance. It is treated with a zinc borate process that resists termites and fungal decay, and it installs more easily than fiber cement because it is lighter and can be cut with standard woodworking tools. LP SmartSide comes with a 5/50-year limited warranty. The concern in Myrtle Beach is moisture: engineered wood handles humidity better than natural wood, but not as well as fiber cement. Proper installation with sealed edges and a quality moisture barrier is critical for coastal longevity.

Aluminum siding was popular in the 1960s through 1980s and still has a niche following. It will not rot, is fireproof, and handles salt air reasonably well. The drawbacks: it dents easily, produces a hollow sound in rain and wind, fades over time, and has a distinctly dated appearance that most homeowners want to upgrade away from. Aluminum is rarely installed new in Myrtle Beach today unless matching an existing commercial building.

Stucco works well on certain architectural styles — Mediterranean, Spanish, and some modern designs. Traditional three-coat stucco is durable and fire-resistant, but it is labor-intensive to install and requires a skilled crew to apply correctly. In Myrtle Beach's climate, stucco is prone to cracking from thermal expansion and moisture intrusion if not properly detailed. EIFS (synthetic stucco) has a troubled history in coastal South Carolina due to moisture trapping issues and is generally not recommended for new residential installations near the coast.

Siding Replacement Cost by Home Size

Home size is the biggest driver of total project cost after material choice. The table below shows estimated total costs for the three most common siding materials in Myrtle Beach. Actual siding area is calculated at approximately 1.25 times the home's living square footage to account for wall height, gable ends, dormers, and soffits.

These ranges assume standard two-story construction with average complexity. Homes with extensive trim work, multiple dormers, complex rooflines, bay windows, or difficult access such as steep lots or tight side yards will land toward the higher end. Simple ranch-style homes with straightforward wall surfaces will be closer to the low end. The estimates include old siding removal and disposal but do not include sheathing repair, which is an additional cost covered below.

Factors That Affect Siding Replacement Cost

Beyond material and home size, several factors specific to your project and the Myrtle Beach market will move the final price up or down. Understanding these helps you avoid surprises when the estimates come in.

Number of Stories

Second and third story work requires scaffolding or lift equipment, which adds $1 to $3 per square foot for the elevated sections. Multi-story homes also take longer to complete because of material handling and safety requirements. A two-story home typically costs 15% to 25% more per square foot than a single-story ranch with the same total wall area, purely because of access.

Old Siding Removal

Removing existing siding adds $1 to $3 per square foot to the project. Vinyl removal is the cheapest and fastest — panels unsnap and pull off quickly. Wood siding removal costs more, especially if it contains lead paint, which is common on pre-1978 homes and requires safe handling procedures. Asbestos-containing siding, found on some homes built before 1980, requires licensed abatement and can add $5 to $15 per square foot for the affected areas. Disposal fees for a typical project run $300 to $800 for non-hazardous materials.

Sheathing Repair

This is the cost that catches most Myrtle Beach homeowners off guard. Once old siding comes off, the wall sheathing and moisture barrier underneath need inspection. In our humid coastal climate, moisture damage behind siding is extremely common — especially on homes with vinyl siding that has been trapping moisture for years. Replacing damaged sheathing (typically OSB or plywood) adds $2 to $5 per square foot for the affected areas. Some homes need only a few patches. Others need entire wall sections replaced. A new weather-resistive barrier adds $0.50 to $1.50 per square foot for the entire project and is required by code and by most siding manufacturer warranties.

Trim, Windows, and Doors

Corner boards, window and door surrounds, fascia, frieze boards, and soffit panels typically add 15% to 25% to the overall siding material cost. Many homeowners underestimate trim. A home with 20 windows, two entry doors, a garage door, and standard corner and fascia trim can easily add $3,000 to $8,000 in trim materials and labor. If you are upgrading from vinyl to fiber cement, the trim should be upgraded to match — mixing PVC or aluminum trim with Hardie board siding creates an inconsistent look and different expansion rates that can cause joint problems.

Architectural Complexity

Bay windows, dormers, turrets, curved walls, multiple roof intersections, and intricate rooflines all increase labor time and material waste. A simple box-shaped ranch with four straight walls costs significantly less per square foot than a home with a dozen angles, bump-outs, and covered porches. Complex homes also require more caulking, flashing, and trim work at every junction point — all of which adds up.

Signs You Need New Siding

Siding does not fail all at once. It degrades gradually, and many homeowners live with deteriorating siding for years without realizing it is costing them money in energy bills, property value, and eventual repair costs. Here are the signs that replacement is overdue:

Warping or Buckling

Siding that is pulling away from the wall, bowing outward, or developing visible waves is no longer doing its job. Warping usually indicates moisture behind the panels, improper installation, or heat damage. In Myrtle Beach, vinyl siding on south-facing and west-facing walls is especially prone to heat warping from direct sun exposure. Once warped, the gaps between panels allow water, insects, and air infiltration.

Cracking and Splitting

Cracks in vinyl siding mean the material has become brittle from UV exposure — a process that accelerates in the intense Myrtle Beach sun. Once vinyl cracks, it cannot be repaired and the affected panels must be replaced. If cracking is widespread across multiple walls, individual panel replacement becomes impractical and full replacement is more cost-effective.

Rot and Soft Spots

Press against your siding in several places, especially near the bottom courses, around windows, and under eaves. If it gives or feels spongy, there is rot behind or within the siding material. Wood siding rots from moisture exposure. Even fiber cement and engineered wood can develop soft spots if water has been entering through failed caulk joints or damaged sections. Rot behind siding means the sheathing and possibly the framing are also compromised.

Mold or Mildew Growth

Some mold on the surface of siding can be power-washed off. But mold that keeps coming back, mold growing at seams and overlaps, or mold visible on the interior walls behind the siding indicates a systemic moisture problem. Myrtle Beach's average 78% summer humidity makes mold an ongoing battle. If your siding is not keeping moisture out, replacement with a properly installed moisture barrier is the only permanent solution.

Rising Energy Bills

Siding is part of your home's thermal envelope. Damaged, warped, or deteriorating siding allows air infiltration that drives up heating and cooling costs. If your energy bills have been climbing and your HVAC system is functioning properly, the siding and the insulation behind it may be the culprit. Modern insulated vinyl siding adds R-2 to R-5, and proper installation with sealed house wrap creates a much tighter building envelope than aging siding with gaps and cracks.

Paint Peeling or Fading

If your painted siding is peeling within 3 to 5 years of a paint job, the problem is usually not the paint — it is moisture coming through the siding from behind. Moisture pushes paint off from the inside out. Repainting is a temporary fix at best. If paint keeps failing prematurely, the siding and moisture barrier system need replacement, not another coat of paint.

Storm Damage

After any hurricane, tropical storm, or severe hailstorm, inspect your siding carefully. Wind-driven debris creates impact damage that may not be obvious from the ground. Hail dents aluminum and cracks vinyl. High winds can loosen fasteners and shift panels out of alignment, creating gaps for water entry. Even if your siding looks intact from a distance, a close inspection after a storm often reveals damage that will lead to moisture problems if not addressed. Storm damage is typically covered by homeowner's insurance.

Partial vs Full Siding Replacement: When Each Makes Sense

Not every siding problem requires tearing off the entire house. Sometimes a partial replacement or targeted repair is the smarter financial move. Here is how to decide:

When Partial Replacement Makes Sense

• Storm damage to one or two walls: If a hurricane damaged the south-facing wall but the rest of the siding is in good condition, replace only the damaged section. Insurance often covers this scenario.
• Localized rot or moisture damage: If rot is limited to areas around one or two windows or at the base of one wall, targeted repair and re-siding of that section is more cost-effective than full replacement.
• Siding is less than 10 years old: If relatively new siding has isolated damage, repair makes sense financially. The remaining siding has significant useful life left.
• Budget constraints with immediate risk: If you cannot afford full replacement right now but one wall has critical issues, partial replacement buys you time until you can address the rest.

When Full Replacement Makes Sense

• Siding is 15+ years old with multiple issues: If you are seeing problems on multiple walls, full replacement is more cost-effective than patching. You also get to inspect and repair the entire sheathing and moisture barrier system at once.
• You are changing materials: Switching from vinyl to fiber cement requires a complete strip because the underlayment, fastening, and trim systems are different. You cannot mix old vinyl with new Hardie board.
• Color matching is impossible: Vinyl siding fades over time. If your original siding color has been discontinued or has faded significantly, new panels will not match the existing ones. This is especially visible in Myrtle Beach where UV fading is accelerated.
• You are selling the home: Full replacement provides a clean, uniform appearance and allows you to market the home with brand-new siding and a transferable warranty. Patched siding raises inspection concerns.
• Widespread moisture damage behind the siding: If the sheathing and moisture barrier need replacement on most of the house, you are taking all the siding off anyway. Full replacement at that point makes economic sense.

A free inspection from a qualified siding contractor will tell you which approach makes the most sense for your situation. WeatherShield provides honest assessments — we will not recommend full replacement if a targeted repair will solve the problem.

Best Siding Materials for Myrtle Beach Coastal Homes

Not every siding material performs the same within a few miles of the Atlantic Ocean. Here are the top three choices ranked for Myrtle Beach conditions, considering durability, wind resistance, moisture performance, maintenance, and total cost of ownership:

#1: James Hardie Fiber Cement (Best Overall)

Hardie board with the HZ10 coastal formulation is the gold standard for Myrtle Beach homes. The HZ10 product line is engineered specifically for hot and humid climate zones with enhanced moisture resistance built into the cement mix itself. It resists salt air corrosion because it is made from inorganic materials — cement and sand that salt cannot degrade. It withstands 150 mph winds when properly fastened. It carries a Class A fire rating. It will not rot, warp, or attract termites. And James Hardie backs it with a 30-year non-prorated warranty plus a separate 15-year ColorPlus finish warranty. The higher upfront cost ($8 to $14 per square foot) is the best long-term investment for any home within 15 miles of the coast.

#2: Insulated Vinyl Siding (Best Budget Option)

If fiber cement is outside your budget, insulated vinyl is the best alternative for coastal Myrtle Beach. The foam backing adds structural rigidity that standard vinyl lacks, improving wind resistance to 160+ mph in some product lines. The insulation also reduces the hollow sound that standard vinyl produces and adds a small energy efficiency improvement (R-2 to R-5 depending on thickness). Insulated vinyl costs $5 to $10 per square foot installed — a meaningful step up from standard vinyl at $4 to $8 without approaching fiber cement pricing. Expect 20 to 25 years of service life in coastal conditions versus 15 to 20 for standard vinyl.

#3: LP SmartSide Engineered Wood (Best Appearance per Dollar)

LP SmartSide gives you the look and feel of real wood siding at a fraction of the cost and maintenance of natural cedar. The engineered wood substrate is treated with SmartGuard, a zinc borate treatment that resists termites and fungal decay. At $6 to $11 per square foot installed, it sits in the middle ground between vinyl and fiber cement. The trade-off for Myrtle Beach homes: engineered wood is more susceptible to moisture damage than fiber cement if edges are not properly sealed during installation. It requires more diligent maintenance — repainting every 5 to 7 years and prompt repair of any damaged caulk joints — to achieve its full 25-year lifespan in our climate. LP SmartSide is a solid choice for homeowners who prioritize the natural wood aesthetic and are willing to stay on top of maintenance.

Siding and Roof Replacement Combo: How to Save

If your roof is approaching end-of-life at the same time your siding needs replacement, combining both projects with one contractor can save significant money:

• Shared mobilization costs: Scaffolding, dumpster rental, and crew setup are one-time costs. When you do siding and roofing together, you pay for these once instead of twice. Typical savings: $1,500 to $3,000.
• Proper integration: The transition between roof and siding is a critical waterproofing junction. Having one crew handle both ensures the flashing, drip edge, and ice-and-water shield are installed correctly where the two systems meet. When different crews handle roofing and siding at different times, this junction is the most common source of leaks.
• One disruption: A combined project means your home is under construction once, not twice. One permit application, one dumpster, one set of scaffolding, one period of noise and dust.
• Package pricing: Most contractors offer a 5% to 10% discount on combined roof-and-siding projects because they can keep their crew on one job site longer with better scheduling efficiency.

WeatherShield Roofing handles both roofing and siding under one roof (no pun intended). Ask about combo pricing when you request your estimate — especially if your roof is within 5 years of needing replacement.

Insurance Coverage for Storm-Damaged Siding

Myrtle Beach sits in a hurricane zone, and storm-damaged siding is one of the most common homeowner's insurance claims in the area. Here is what you need to know about filing a claim for siding replacement:

• Covered perils: Hurricane winds, hail, tornado, falling trees, and fire are all covered under standard homeowner's policies. If any of these damaged your siding, the replacement cost should be covered minus your deductible.
• Not covered: Normal wear and tear, sun fading, age-related deterioration, and maintenance neglect are not covered. Your insurance company will not pay to replace siding that simply reached the end of its useful life.
• Wind/hail deductible: Many Myrtle Beach homeowner's policies have a separate wind/hail deductible that is a percentage of the home's insured value (typically 2% to 5%) rather than a flat dollar amount. On a $300,000 home, a 2% wind deductible is $6,000 out of pocket.
• Documentation is critical: Take photos of the damage immediately after the storm. File the claim within the time limit specified in your policy (usually 1 to 2 years for wind damage in SC). Do not start replacement work until the insurance adjuster has inspected and documented the damage.
• Matching requirement: South Carolina law allows you to argue for replacement of all matching siding if the damaged sections cannot be matched in color, profile, or material. This can turn a partial claim into a full siding replacement if the insurance company cannot find matching materials.

WeatherShield Roofing works with insurance claims regularly and can help you navigate the process. We document the damage, provide the detailed estimate your adjuster needs, and coordinate timing so the work starts as soon as the claim is approved.

How Long Does Siding Replacement Take?

The timeline for siding replacement depends on your home's size, the material being installed, and whether sheathing repairs are needed. Here are realistic timeframes for Myrtle Beach projects:

Fiber cement takes longer than vinyl to install because the material is heavier (a single HardiePlank board weighs about 2.5 pounds per square foot versus less than half a pound for vinyl), requires specialized cutting tools to avoid silica dust, and demands more precise fastening. The extra time is not wasted — it produces a more durable result.

Weather is a factor in Myrtle Beach scheduling. Rain delays are common during summer storm season (June through September). Siding cannot be installed in active rain because the moisture barrier and sheathing must stay dry. Most contractors prefer spring (March through May) and fall (October through November) for siding work when the weather is more predictable and crew availability is better.

South Carolina Building Code for Siding Replacement

Siding replacement in Myrtle Beach is not a DIY-friendly project from a code standpoint. The City of Myrtle Beach and Horry County enforce the International Residential Code (IRC) with South Carolina-specific amendments. Here are the key code requirements that affect your siding project:

• Building permit required: A permit is required for siding replacement in Myrtle Beach and all of Horry County. Your contractor should pull the permit and schedule required inspections. Unpermitted work can create title issues when selling and may void manufacturer warranties.
• Wind resistance requirements: Homes in Myrtle Beach's wind zone must use siding materials and fastening methods rated for the local design wind speed. The basic wind speed for Myrtle Beach is 150 mph per ASCE 7. Your siding installation must be engineered to resist these forces, which means specific fastener type, spacing, and attachment to structural framing — not just sheathing.
• Weather-resistive barrier: IRC Section R703.1 requires a weather-resistive barrier behind all exterior wall coverings. This is typically a house wrap (like Tyvek or similar) installed over the sheathing before the siding goes on. It is not optional regardless of the siding material.
• Flashing at penetrations: Every window, door, utility penetration, and wall-to-roof junction must have proper flashing installed per code. This is the most common area where code violations occur and the most common source of water intrusion.
• Fire resistance in certain zones: If your home is in a high-density area or near a commercial zone, the exterior wall assembly may need to meet fire resistance requirements. Fiber cement siding with its Class A rating automatically meets these requirements.

A licensed siding contractor handles all code compliance, permits, and inspections as part of the project. This is not something to cut corners on. Code-compliant installation protects your home, preserves your warranty, and prevents legal issues when you sell.
