Backyards wear out slowly and then all at once. A deck that skipped a season of finish starts to check and crack; a grill that was never cleaned becomes a fire risk; cushions left out through a wet autumn grow mildew. Most of this is avoidable with a short routine tied to the seasons. This checklist covers the main parts of an outdoor living space, wood decks, patios, furniture, grills and fire pits, and storage, with guidance from the USDA Forest Service’s Forest Products Laboratory, the National Fire Protection Association (NFPA), the Seattle Fire Department and local public health advice. Product instructions take priority for anything you clean, finish or service.

The yearly rhythm: inspect and clean in spring, protect and keep up in summer, clean and store in fall, and check on stored items in winter. Two tasks matter most for safety: clean the grill and check propane equipment before the first use of the year, and keep fire features a safe distance from anything that can burn.

Spring: inspect, clean and get ready

Decks

Walk the deck looking for loose or popped fasteners, soft or split boards, wobbly railings and stairs, and mildew. The Forest Products Laboratory (FPL) explains that weather makes deck boards swell and shrink, and that without maintenance decks develop checks, cracks, raised grain and mildew, which raise the risk of decay and insect attack. Its guidance on cleaning:

  • Commercial deck cleaners or brighteners remove mildew and dirt and restore colour without adding stain.
  • Avoid aggressive scrubbing with caustic cleaners or power washing, which can strip wood from the surface, especially on softer woods such as western redcedar.
  • Mildew can be removed with household bleach diluted with three parts water plus some detergent. Never use a detergent containing ammonia, which reacts with bleach to form a toxic gas. Rinse the deck with water afterwards.
  • If you will refinish after cleaning, FPL advises allowing at least two warm, windy days for the wood to dry.

Patios and paths

Sweep, then look for lifted pavers, cracks, low spots where water pools, and weeds in joints. Reset sunken pavers and top up joint sand. Check that water still runs away from the house. See patio cleaning.

Grill

Before the first cookout, NFPA advises checking a propane grill’s gas tank for leaks and removing grease or fat build-up from the grates and the trays below. NFPA’s data show the grill had not been cleaned in about one in five grill fires. Confirm the grill’s position is well away from the house and deck railings and not under eaves or overhanging branches.

Furniture

Bring out stored furniture, wash frames, tighten hardware and check cushions for mildew. Details by material are in outdoor furniture care.

Standing water

Start a weekly tip-and-toss routine. Mecklenburg County, North Carolina, advises emptying anything that holds water once a week, because mosquitoes can develop from egg to adult in 7 to 14 days. Common sources include plant saucers, buckets, watering cans, bird baths, pet bowls, children’s toys, tarps over woodpiles, wheelbarrows and bins.

Summer: protect and keep up

Refinish the deck when it needs it

Summer’s dry spells are the usual time to refinish. The FPL recommends penetrating finishes, such as water-repellent preservatives, coloured water-repellent preservatives and semitransparent stains, over film-forming finishes such as paint and solid-colour stain on deck surfaces. Film finishes wear quickly under foot traffic and can trap moisture and peel; penetrating finishes are easier to reapply. FPL notes a clear water-repellent preservative lasts about a year on exposed deck surfaces, while pigmented finishes last longer. Railings, which see no foot traffic, can take paint or solid stain. FPL observes that most decks are retired because of cracks and checks that timely finishing could have largely prevented.

Grill and fire pit habits

  • Clean grease from the grill regularly; never leave a lit grill unattended.
  • Let charcoal cool completely before disposing of it in a metal container, per NFPA.
  • Keep a 3-foot zone around the grill and fire pit for children and pets.
  • Check local fire restrictions in dry spells before lighting a fire pit; NFPA advises checking the local fire danger rating.

Ongoing

  • Bring cushions in or cover them before rain.
  • Continue the weekly standing-water check.
  • Trim plants away from fences, structures and the grill area.

Fall: clean and store

Clear leaves and debris

Wet leaves left on decks and patios stain surfaces and hold moisture against wood. Sweep them off regularly, and clear gaps between deck boards so water drains. Leaves make good compost material.

Furniture and cushions

Clean and dry everything before storing; mildew grows on items put away damp. Store cushions indoors or in a ventilated deck box. Furniture that stays out should be covered with breathable covers. See outdoor equipment storage.

Fire pits and heaters

Cooler evenings bring heavier fire pit use. The Seattle Fire Department advises keeping fire pits at least five feet from the house, vegetation and anything that can burn, on a non-combustible surface rather than a wood deck or grass, and keeping water, a hose or an extinguisher ready. For patio heaters, keep anything that can burn at least three feet away, place them where they cannot tip, and turn them off when the area is empty. Children’s Wisconsin notes fire pits can stay hot for 24 hours after a fire looks out, so let ashes cool fully and wet them before removing.

Water lines

Where winters freeze, drain and disconnect garden hoses, shut off and drain outdoor faucets if your house has an interior shutoff, and empty drip irrigation lines and fountains.

Grill

Give the grill a full clean before storage. Propane supplier Ferrellgas advises storing cylinders outdoors in a well-ventilated, shaded spot, upright and at least 10 feet from flammable materials, and never in a garage, shed, basement or storage unit, where vapour from a valve that is not fully closed can collect.

Winter: protect and plan

  • Before clearing snow or using deicer on decks and pavers, check the decking or paver manufacturer’s care instructions and the deicer label for the surfaces it is safe on.
  • Check on stored furniture and covers after storms.
  • Plan projects for spring, including any repairs found during the year. If a project involves digging, book an 811 utility locate a few business days before work starts.
