When weeds and moss start growing in the joints of a retaining wall cap, it’s a sign that moisture is trapped and the seal between the blocks has broken down. In Lombard, IL, many single-family homes and townhomes have retaining walls that are exposed to rain, snow melt, and high humidity. Over time, organic matter builds up in the joints, creating a damp environment where moss and weeds take root.<\/p>\n
If left unchecked, the roots of weeds can widen the gaps between cap blocks, moss retains moisture that accelerates freeze-thaw damage, and the overall appearance of the wall deteriorates. For homeowners in Lombard and nearby suburbs, cleaning the joints and resealing the cap is a practical maintenance task that protects the wall structure.<\/p>\n

The fix involves removing all plant matter, cleaning the joints thoroughly, replacing any deteriorated joint material, and applying a sealant to prevent regrowth. If the cap blocks are loose or damaged, they should be reset or replaced during the cleaning process.<\/p>\n Retaining wall caps are exposed to the elements, and several factors contribute to weed and moss growth in the joints:<\/p>\n For minor weed and moss growth, a careful homeowner can pull the weeds by hand, scrub the moss with a stiff brush and a mild cleaning solution, and rinse the joints with a pressure washer on a low setting. After the joints are clean and dry, apply a joint sealant to prevent regrowth.<\/p>\n However, if the infestation is extensive, the cap blocks are loose, or the wall structure is compromised, professional cleaning and repair is recommended. A handyman can remove all organic matter, check the wall for structural issues, and properly reseal the joints for long-lasting results.<\/p>\n Step 1:<\/strong> Remove all visible weeds and moss by hand. Use a stiff brush to scrub the joints and dislodge embedded organic matter.<\/p>\n Step 2:<\/strong> Rinse the joints with a pressure washer on a low setting. Let the wall dry completely. Check for loose or damaged cap blocks.<\/p>\n Step 3:<\/strong> Reset any loose cap blocks with construction adhesive. Replace damaged blocks if needed. Fill the cleaned joints with exterior-grade sealant.<\/p>\n Step 4:<\/strong> Apply a moss inhibitor or sealant to the cap surface to prevent future growth. Clean up the surrounding area and monitor the wall over the following months.<\/p>\n Lombard is a village just west of Chicago with a mix of historic homes, newer developments, and townhomes.
