2.3 Wood Treatment: Sealants, Stains, and Rot Prevention

Wood remains a popular pergola material for aesthetic appeal, but its longevity depends on proper treatment. Hardwoods like teak and cedar resist decay naturally, yet applying water-repellent sealants and UV-resistant stains extends lifespan. Softwoods require pressure treatment or chemical preservatives to resist rot and insect damage. Installation steps include:

1. Sealing all cut edges immediately to prevent moisture ingress.

2. Applying two coats of stain or sealant to exposed surfaces, reapplying every 1–2 years.

3. Ensuring drainage around posts to prevent standing water at the base.

When maintained correctly, treated wood can last decades while preserving natural beauty, though it requires more ongoing attention than metals like aluminum or coated steel.

3.Maintenance Requirements by Material

Proper maintenance ensures that pergolas retain their structural integrity and aesthetic appeal over time. Aluminum structures, including Aluminum pergola house, require minimal upkeep compared to wood or steel.
