Winter Preparation

Winter in New Hampshire can be brutal. To protect your deck, start by thoroughly cleaning it. Remove any debris, leaves, or dirt that could trap moisture and lead to mold or mildew. Once clean, apply a high-quality water-repellent sealant to prevent water from seeping into the wood.

Consider using a tarp or cover to shield the deck from snow and ice. If your area is prone to heavy snowfall, regularly clear snow using a plastic shovel to avoid damaging the wood surface.

Spring Maintenance

As snow melts and temperatures rise, inspect your deck for any winter damage. Look for loose boards, popped nails, or signs of rot. Repair any issues promptly to prevent further deterioration.

Spring is also an excellent time to reseal your deck. A fresh coat of sealant will protect against spring showers and prepare the deck for the coming summer heat.

Summer Care

During the summer, decks become a focal point for outdoor activities. To keep yours in top condition, regularly sweep away dirt and debris. Consider using a mild soap solution to clean the surface and prevent stains from spills or food.

If your deck gets direct sunlight, think about adding some shade. Umbrellas, pergolas, or awnings can help protect the wood from UV damage and make the space more comfortable for use.

Fall Preparations

Fall is a critical time to prepare your deck for the winter months. Start by giving it a thorough cleaning, clearing away fallen leaves and debris. Leaves can trap moisture and cause staining if left unchecked.

Inspect your deck for any repairs needed after summer use. Tighten loose screws and replace any damaged boards to ensure the structure is sound before the cold sets in.

Year-Round Tips

Regardless of the season, regular maintenance is key to extending the life of your deck. Schedule routine checks and cleanings, and address any issues as soon as they arise. This proactive approach will keep your deck safe and beautiful year-round.
