Maintaining your pergola is essential to keep it looking its best and prolong its lifespan. Regular maintenance tasks include cleaning the structure to remove dirt, debris, and stains. Depending on the material used, you may need to apply a protective sealant, stain, or paint to prevent damage from the elements. Inspect the pergola periodically for any signs of wear, such as loose or damaged components, and repair or replace them as needed. Lastly, trim any nearby vegetation to prevent overgrowth or contact with the pergola, which can cause damage or reduce airflow.
