Malta Construction Siding: What It Is and How It Works in South Carolina

Malta Construction siding is a fiber-cement product made from wood fibers, Portland cement, and sand, pressed together under high pressure and heat

Malta Construction siding mimics the look of wood lap siding but uses cement and fiber instead of lumber. The material comes in planks that overlap like traditional wood, and it's manufactured to resist rot, insects, and weather damage—problems that plague real wood in South Carolina's humid climate. You'll find it sold under the brand name Hardie Board (the most common version), though other manufacturers produce similar products.

The siding is installed over a house's exterior frame and sheathing, just like wood siding would be. Contractors nail or screw the planks to the wall, leaving small gaps for expansion and contraction. Once installed, the surface is typically painted or stained, and it requires periodic maintenance to keep the finish intact.

Key Takeaways

• Malta Construction siding resists rot, termites, and moisture damage far better than wood, making it practical for South Carolina's climate.
• The material costs more upfront than vinyl or wood but lasts 25 to 30 years with proper maintenance.
• Installation requires cutting and fastening planks to the house frame, and the work should be done by contractors experienced with fiber-cement products.
• The surface must be painted or stained every 7 to 10 years to maintain water resistance and appearance.

How Malta Construction Siding Performs in South Carolina's Climate

South Carolina's combination of heat, humidity, and salt air (especially near the coast) breaks down wood siding quickly. Malta Construction siding handles these conditions better because the fiber-cement blend doesn't absorb moisture the way wood does, and it won't rot or become a food source for termites. The material also resists mildew growth, which thrives in humid environments.

The siding does expand and contract slightly with temperature and humidity changes, which is why installers leave small gaps between planks. In coastal areas, the salt air can eventually corrode fasteners if they're not stainless steel, so contractors should use corrosion-resistant nails or screws. The paint or stain finish is what actually protects the cement underneath from water penetration, so maintaining that finish is critical to the siding's longevity.

Installation Process and What to Expect

Malta Construction siding installation begins with the contractor measuring and planning the layout so the planks align properly around windows, doors, and corners. The first plank is nailed to a starter strip at the foundation line, and each subsequent plank overlaps the one below it by about 1.25 inches. Contractors use a nail gun or drill to fasten planks every 16 inches along the studs underneath.

Cutting the planks requires a circular saw or fiber-cement shear, and the dust created during cutting contains silica, which can damage lungs if inhaled. Professional installers use wet-cutting methods or dust collection equipment to manage this hazard. Once all planks are in place, contractors install trim around windows and doors, seal all joints with caulk, and prepare the surface for painting.

The entire installation process typically takes several weeks, depending on the size of the house and weather conditions. Contractors must wait for caulk to cure and primer to dry before applying finish paint. Most painters recommend two coats of exterior paint to ensure durability.

Cost Comparison: Malta Construction Against Other Siding Options

Malta Construction siding costs more per square foot than vinyl siding but less than real cedar or composite alternatives. Material costs vary by region and supplier, but fiber-cement typically runs higher than vinyl because of its durability and the labor required to install it safely. Installation labor is also more specialized—contractors need experience with cutting and fastening fiber-cement without creating silica dust hazards.

Over a 30-year period, Malta Construction often costs less than wood siding because wood requires more frequent repainting, repair, and eventual replacement. Vinyl siding is cheaper upfront but may need replacement sooner in extreme weather, and it doesn't offer the same authentic wood appearance. The choice depends on your budget, how long you plan to stay in the house, and whether the aesthetic matters to you.

Maintenance Requirements and Lifespan

Malta Construction siding lasts 25 to 30 years with proper care, but the paint or stain finish needs refreshing every 7 to 10 years. In South Carolina's intense sun and humidity, the finish may fade or peel sooner, especially on south-facing walls. Repainting involves power-washing the surface to remove mildew and loose paint, then applying primer and two coats of exterior paint.

Between paint jobs, inspect the siding for cracks, especially after storms or temperature swings. Small cracks can be caulked, but large cracks or splits may indicate a structural problem and should be evaluated by a contractor. Check that caulk around windows and doors remains intact and flexible—dried-out caulk should be removed and replaced to prevent water from entering the wall cavity.

The fasteners holding the planks in place can rust if they're not stainless steel or galvanized, so look for signs of rust staining. If you see rust, the fastener should be replaced before it weakens the connection. Gutters should be kept clean so water drains away from the siding rather than pooling against it.

Common Problems and How to Address Them

The most common issue with Malta Construction siding is paint failure—peeling, chalking, or fading—which happens when the finish breaks down and stops protecting the cement underneath. This is normal wear and requires repainting. Delaying repainting can allow water to penetrate the siding and cause damage to the sheathing and framing behind it.

Cracks in the planks themselves are less common but can occur if the house settles unevenly or if a plank was damaged during installation or by impact. Small cracks can be caulked and painted over. Larger cracks usually mean the plank should be replaced, which requires removing fasteners and sliding out the damaged piece.

Moisture problems behind the siding often result from poor installation—gaps left unsealed, fasteners driven through the paint, or caulk that wasn't applied where planks meet trim. If you notice soft spots, mold, or water stains on the interior walls, the siding may not be shedding water properly, and a contractor should inspect the installation.

Choosing a Contractor for Malta Construction Installation

Not all siding contractors have experience with fiber-cement products, so ask specifically whether they've installed Malta Construction or Hardie Board before. Request references from recent projects and ask those homeowners about the quality of the work and whether any issues arose after installation. A contractor who understands the silica hazard and uses proper dust control methods is more likely to do safe, quality work.

Get written estimates from at least two contractors that break down material costs, labor, and any additional charges for prep work, trim, or painting. Ask whether the estimate includes caulking, primer, and paint, or whether those are separate. Clarify the warranty—most manufacturers warrant the product itself, but the contractor should also warranty their labor for a set period.

Check that the contractor is licensed and insured in South Carolina. Fiber-cement siding installation involves working at heights and handling materials that create dust hazards, so liability insurance is important. Ask about the timeline and whether the contractor can work around your schedule or weather delays.

Frequently Asked Questions

How does Malta Construction siding compare to Hardie Board?

Malta Construction and Hardie Board are essentially the same product—fiber-cement siding made from wood fibers, Portland cement, and sand. Hardie Board is the most widely available brand in the United States, while Malta Construction is another manufacturer's version. The performance and maintenance are nearly identical.

Can I paint Malta Construction siding myself, or do I need a professional?

You can paint it yourself if you're comfortable with exterior work and have the right equipment, but hiring a professional painter ensures the job is done correctly and lasts longer. The surface must be properly prepped—power-washed and primed—before painting, and two coats of quality exterior paint are recommended. Poor prep work or cheap paint will fail faster.

What happens if Malta Construction siding gets wet during installation?

Fiber-cement can absorb moisture, which can cause swelling and warping if it dries unevenly. Contractors should protect the siding from rain during installation and allow it to acclimate to the local humidity before fastening it to the house. If siding gets soaked, it should be allowed to dry slowly in shade rather than in direct sun.

Is Malta Construction siding fire-resistant?

Yes, fiber-cement is non-combustible and has a Class A fire rating, the highest rating for exterior materials. This can lower homeowners insurance premiums in some cases, though rates vary by insurer and location. Check with your insurance agent about potential savings when switching to fiber-cement siding.

Can Malta Construction siding be installed over existing siding?

It's possible but not recommended. Installing over old siding can trap moisture and create an uneven surface that makes the new siding look wavy. Most contractors remove the old siding first, inspect the sheathing for damage, and repair or replace it before installing new fiber-cement planks.
