What Is Cypress Wood?
Bald Cypress (Taxodium distichum) is a native American softwood with exceptional natural decay resistance — often called "the wood eternal" by Southern builders who have used it for centuries. Growing in the swamps and wetlands of the southeastern United States, Cypress has evolved unique chemical compounds (cypressene) that make it naturally resistant to rot, insects, and moisture.
While technically a softwood (510 lbf Janka), old-growth Cypress heartwood has decay resistance rivaling many tropical hardwoods. The wood's natural preservative oils — particularly in old-growth and sinker cypress — provide excellent protection without chemical treatment. Modern second-growth Cypress is still highly durable, though slightly less so than the legendary old-growth material.
Cypress features a light yellowish-brown to medium brown color with a straight, fine grain. It's easy to work with standard tools, takes stain and paint well, and is significantly lighter than tropical hardwoods — making handling and installation easier. Its combination of durability, workability, and domestic sourcing makes it a popular choice for siding, fencing, outdoor structures, and anywhere rot resistance matters.
Key Facts
- Called "the wood eternal" for centuries of proven rot resistance in the South
- Natural cypressene oil provides chemical-free decay and insect resistance
- Lightweight and easy to work — no special tools required
- Domestically sourced from sustainably managed southeastern US forests
- Takes stain, paint, and clear finishes exceptionally well
- Significantly more affordable than tropical hardwoods
Why Choose Cypress?
Natural Rot Resistance
Cypressene oil provides natural preservation — no chemical treatment needed for above-ground outdoor use
Insect Resistant
Natural compounds repel termites, carpenter ants, and other wood-boring insects

Cypress Siding
Cypress siding is the traditional choice for Southern homes and has proven its durability over centuries of service in the humid, insect-rich southeastern climate. Its natural cypressene oil protects against rot and termites without chemical treatment, and its straight grain creates clean, attractive lap siding, board-and-batten, and shiplap installations. Cypress siding takes paint and stain exceptionally well — better than most other woods — providing unlimited color options while maintaining natural protection underneath. The wood's lightweight nature (32 lbs/ft³) makes handling and installation easy, and its moderate price offers excellent value compared to both tropical hardwoods and premium cedar.

Cypress fencing leverages centuries of proven rot resistance in the most demanding Southern climates. Its natural oils protect against termites and decay without the chemicals found in pressure-treated alternatives — making it safe for garden borders, animal enclosures, and children's play areas. Cypress fence posts and pickets resist moisture absorption and maintain structural integrity for 20-30+ years. The wood can be left natural for a rustic weathered look, stained for custom color, or painted for a traditional appearance. For homeowners in the Southeast who want a chemical-free, naturally durable fence, Cypress is the clear heritage choice.

Cypress is an excellent choice for pergolas, arbors, raised garden beds, dock structures, and outdoor furniture throughout the southeastern United States. Its natural decay resistance means these structures last decades without pressure treatment, and the lightweight wood is easy to cut, shape, and assemble on-site. Cypress's moderate cost compared to tropical hardwoods makes it practical for large structures where material volume is significant. The wood accepts all finishes — from transparent stains that showcase the grain to solid paints for a polished look.

- Standard tools work well — no carbide tooling or pre-drilling needed
- Can be nailed directly without splitting in most applications
- Use stainless steel or hot-dipped galvanized fasteners for exterior use
- Allow to acclimate 5-7 days before installation
- Apply a UV-protective stain or finish for best color retention
- Heartwood provides the best decay resistance — specify heartwood for ground-proximity applications

Maintenance & Care
Cypress is low-maintenance compared to treated lumber. Its natural oils protect against decay without chemical treatment.
Finishing Options
Cypress can be left unfinished for a natural weathered gray look, stained for custom color, or painted for a traditional appearance. All approaches work well. A penetrating UV stain provides the best color retention.
Cleaning
Clean with mild soap and water or a deck cleaner. Power wash on low setting for deeper cleaning. Reapply stain or sealer every 2-3 years for exterior applications.
Heartwood vs Sapwood
Cypress heartwood provides natural decay resistance. Sapwood does not. For maximum durability in exterior applications, specify heartwood-only or "select" grade material.
Important Considerations
Softer Surface
At 510 Janka, Cypress dents and scratches more easily than hardwoods. Best for low-to-moderate traffic areas and vertical applications.
Second Growth vs Old Growth
Modern second-growth Cypress is less decay-resistant than legendary old-growth material. Still durable, but manage expectations accordingly.
Sapwood Not Durable
Only heartwood has natural decay resistance. Sapwood will decay if exposed to moisture. Specify heartwood for exterior applications.
