Our Guide to Essential Deck Maintenance for Every Season

Spring Cleaning and Inspection
After winter, your deck needs a thorough refresh. We recommend starting with a comprehensive inspection. Check for any loose boards, protruding nails, or signs of rot that may have appeared. Pay close attention to the ledger board where the deck attaches to your house, ensuring it's secure. Once you've made any necessary repairs, it's time for a deep clean. Use a deck-specific cleaner to gently scrub away mildew and grime. A light power washing can be effective, but be sure to use a low-pressure setting to avoid damaging the wood fibers.

Summer Protection and Care
The intense South Texas summer sun can be harsh on your deck. This is the perfect time to apply a quality sealant or stain with UV protection. This vital step shields the wood from sun damage, prevents moisture from seeping in, and keeps your deck looking its best. We suggest testing the wood's seal by sprinkling some water on it; if the water beads up, the seal is strong. If it soaks in, it’s time to reapply. Regular sweeping to remove dirt and leaves will also prevent stains and keep the surface safe.

Autumn Preparation for Winter
As the weather cools, your main task is to keep the deck clear of debris. Fallen leaves, pine needles, and twigs can trap moisture, which is a primary cause of mold, mildew, and rot. Make it a habit to sweep your deck regularly throughout the fall. This is also a good time to give it another gentle wash to clean off any grime accumulated over the summer. Trim back any overhanging tree branches to reduce the amount of debris that falls onto the deck and to prevent damage during storms.

Winter Watch and Planning
Our South Texas winters are milder than in other places, but it's still important to keep an eye on your deck. Continue to sweep off any leaves or debris that accumulate. Avoid using harsh chemical ice melts on the wood, as they can cause discoloration and damage. Instead, use a plastic shovel for any clearing. Winter is also the perfect season for planning. If you noticed areas needing significant repairs or are dreaming of an expansion, now is the time to design the project and gather material lists for the spring.
Your deck is a valuable part of your home, and with a little attention each season, you can ensure it lasts for decades. Our experience has shown us that the best outdoor spaces start with quality materials and are maintained with consistent care. This understanding is at the core of everything we do.
