A well-maintained deck adds value, beauty, and usable space to your home. It’s a great spot for relaxing, entertaining, or simply enjoying your backyard. But to keep it safe and looking its best, routine deck maintenance is key. From seasonal cleaning to repairs and inspections, here’s what you need to know to care for your deck year-round.
Deck Maintenance Includes Cleaning
One of the easiest ways to extend the life of your deck is to keep it clean. Dirt, leaves, pollen, and mold build up over time, leading to discoloration and surface damage. A cleaning twice a year—once in the spring and again in the fall— makes a big difference.
Start by removing furniture, grills, and planters. Sweep away debris and check for areas with trapped moisture. For a deeper clean, use a deck cleaner and a stiff brush or power washer on a low setting. Rinse it thoroughly and allow the deck to dry completely before replacing your furniture.
If your deck has mildew or algae, a mixture of water and mild detergent or white vinegar can help. Avoid using bleach on wood decks, as it weakens the wood fibers over time.
Check for and Repair Damage
Once your deck is clean and dry, look for any problems that might need fixing. Walk around the entire structure and check the boards, railing, stairs, and fasteners. Look for any loose or sticking-out nails or screws and replace or tighten them as needed to avoid injury. If you find cracked or split boards, it’s best to replace them before the damage spreads. Pay special attention to railings and stairs—if they feel wobbly or unstable, secure them right away to prevent safety issues.
You should also watch for soft spots, rot, or any sections that feel spongy underfoot. These areas often appear near where the deck connects to the house or close to the ground. Rot and moisture damage can worsen quickly, so act fast if you notice these warning signs. Also, inspect the metal connectors and fasteners that help support the structure. If you spot rust or corrosion, it may be time to replace them with new, rust-resistant hardware.
Reseal or Re-stain When Needed
Wood decks need periodic sealing or staining to protect against moisture, sun damage, and general wear. Depending on weather exposure and foot traffic, most decks benefit from a fresh coat every two to three years. To check if it’s time to reseal, sprinkle water on the surface. The protective layer has worn off if it soaks in rather than forming beads.
Choose a quality deck sealant or stain designed for outdoor use. Follow the manufacturer’s instructions and apply it during mild weather for the best results. Always work with a clean, dry surface and use even strokes for a smooth finish. This simple step can extend the life of your deck and keep it looking like new.
Schedule a Professional Deck Inspection
Even with regular upkeep, some issues can go unnoticed without a trained eye. A professional home inspector can perform a detailed deck inspection to evaluate its structure and safety—especially if your deck is older or hasn’t been checked in several years.
During an inspection, the inspector will look at the ledger board, posts, joists, fasteners, and overall construction. They’ll also examine the connection points, check for wood rot or insect damage, and verify that the deck meets current safety standards. A proper inspection gives you confidence that your deck is structurally sound and can help identify small problems before they become larger, costlier repairs.
Preventative Deck Maintenance Tips
You can take a few extra steps to help prevent damage throughout the year. Trim back any overhanging tree branches or nearby bushes to improve airflow and reduce the buildup of leaves and moisture. Move furniture, rugs, and planters occasionally to prevent uneven fading and moisture marks. In winter, clear snow using a plastic shovel to avoid scratching the surface, and avoid using harsh ice-melting products. If you use a grill on your deck, place a mat underneath it to protect against grease stains and reduce the risk of fire.
Caring for your deck doesn’t have to be complicated. With regular cleanings, timely repairs, and professional inspections, you can keep your deck safe, beautiful, and ready for years of use. If you’re unsure about your deck’s condition, scheduling an inspection is a smart and easy first step.
Frequently Asked Questions About Deck Maintenance
How often should I clean my deck?
Cleaning your deck at least twice a year—typically in the spring and fall—is recommended. If your deck is exposed to lots of leaves, moisture, or shade, more frequent cleanings may help reduce the buildup of mold and mildew.
What’s the best way to remove mildew from a wood deck?
A solution of water and white vinegar works well to scrub away mildew. Use a stiff brush to clean the affected area, then rinse thoroughly and allow the surface to dry.
Can I inspect my deck myself?
While you can look for surface-level issues like loose boards or visible rot, a professional home inspector has the training to evaluate hidden damage, structural integrity, and code compliance.
How long does a deck inspection take?
Most professional deck inspections take between 30 and 60 minutes, depending on the deck’s size, age, and condition.
Is staining better than sealing?
Staining adds color and protects the wood, while sealing is typically clear and focuses more on water resistance. Some products offer a combination of both. The best option depends on your deck’s material and the look you want to achieve.
