Maintenance Guides

Utah-specific advice based on our experience across Salt Lake County and the Wasatch Front.

🌞

Deck Maintenance in Utah's High-UV Climate

Utah sits at over 4,200 ft elevation — UV radiation is 25–50% more intense than at sea level. That accelerates wood fading, stain breakdown, and sealer failure faster than most national product timelines assume.

  • ✓Inspect and re-apply UV-blocker sealer every 1–2 years (not the 3–5 years listed on most national product labels).
  • ✓Clean off pollen, dust, and bird droppings monthly — they trap UV-accelerating moisture.
  • ✓Use semi-transparent or solid-color stains in high-sun areas; clear sealers offer almost no UV protection.
  • ✓West-facing decks in SLC should be inspected each September after peak summer sun exposure.

Protecting Your Deck Through Freeze-Thaw Cycles

Salt Lake City averages 30+ freeze-thaw cycles per year. Water gets into micro-cracks, freezes, expands, and widens them — turning hairline surface cracks into board-splitting damage within a season or two.

  • ✓Seal all surface cracks before October — even small ones — with a penetrating wood sealer.
  • ✓Clear all standing water from your deck surface after rain or snow melt; don't let it pool.
  • ✓Remove snow with a plastic shovel, not metal-edged tools that scratch the surface coating.
  • ✓Inspect fasteners and board ends each spring — freeze-thaw makes fasteners work loose and end-grain rot more likely.

Composite vs. Wood Deck Maintenance

Composite decks need less refinishing than wood but are not maintenance-free — especially in Utah's dusty, high-UV, freeze-thaw environment.

  • ✓Wood decks: sand, clean, re-stain, and re-seal every 2–3 years in Utah's climate.
  • ✓Composite decks: power wash annually; check for mold behind boards; inspect fasteners every 3 years.
  • ✓Never sand composite decking — it exposes the wood-fiber core to moisture.
  • ✓Composite boards still need board-end protection from snowmelt and winter moisture.

When to DIY vs. Call a Pro

Some deck maintenance tasks are safe for experienced DIYers. Structural work — anything involving joists, ledger boards, or railings — is not.

  • ✓DIY-safe: Cleaning, power washing (1200–2000 PSI), and applying fresh stain/sealer on sound boards.
  • ✓Call a pro: Any board replacement, railing work, joist repair, or structural reinforcement.
  • ✓DIY-risk: Renting a pressure washer and using too high a PSI can strip the wood grain — 1500 PSI max for softwood.
  • ✓If in doubt, get a free assessment — we'll tell you honestly what's urgent and what can wait.

🔍 Repair vs. Replace Decision Guide

Match your deck's symptoms to the right response. When in doubt, get a free assessment — we'll give you an honest answer.

✓ Repair

Surface discoloration, gray color, fading stain

Sand and re-stain — common after 3–5 Utah winters.

✓ Repair

Hairline surface cracks (< 1/4" wide)

Fill with wood filler, seal the board end, re-stain.

✓ Repair

1–3 soft or spongy boards in otherwise solid deck

Replace affected boards. Check joists underneath for moisture.

✓ Repair

Loose or wobbly railings

Likely fastener failure. Rebolt or sistering. Urgent safety issue.

⚠ Replace

More than 30% of boards soft, cracked, or rotted

Board-by-board repair exceeds rebuild cost. Full deck replacement is smarter.

⚠ Replace

Rotted ledger board or main beam

Structural failure risk. Full rebuild required by code in most Utah jurisdictions.

⚠ Replace

Sagging, uneven, or visibly tilting deck frame

Foundation/post failure. Do not use until professionally assessed — liability risk.

❓ Frequently Asked Questions

Common questions from Utah homeowners about deck care, costs, and timing.

How much does it cost to resurface a deck in Salt Lake City?
A full deck refinishing in the SLC area typically runs $800–$2,500 for a standard 400 sq ft deck, including power washing, light sanding, and 2 coats of premium stain and sealer. Structural repairs (board replacement, joist work) are priced separately. Request a free quote for an exact number specific to your deck.
When is the best time to refinish a deck in Utah?
May through September is ideal — temperatures above 50°F, low humidity, and no rain in the forecast for 24–48 hours. Avoid refinishing in direct sun above 90°F as stain dries too fast and can lap. Early morning or evening application works best in Utah's summer heat.
How often should I reseal or re-stain my deck in Utah?
Due to Utah's high UV index and 30+ annual freeze-thaw cycles, we recommend: re-sealing every 1–2 years for clear/semi-transparent finishes, and a full refinishing every 2–3 years for solid stains. National product labels often say 3–5 years — that's for coastal climates. Utah is harder on finishes.
How do I know if my deck needs repair or full replacement?
If fewer than 30% of your boards are soft or rotted, and the frame/joists are structurally sound, targeted repairs usually make financial sense. If the main beam, ledger board, or joists are rotted or compromised, or if more than 30-40% of decking needs replacement, a full rebuild is typically cheaper long-term. When in doubt, get a free professional assessment — we'll give you an honest answer.
What's the best deck stain for Utah's climate?
Look for stains with UV blockers (zinc or titanium dioxide) rated for western or desert climates. Defy Extreme, Armstrong Clark, and Ready Seal all perform well in the SLC area. Avoid clear sealers alone — they provide almost no UV protection. Semi-transparent formulas offer the best balance of protection and natural wood look.
Can I power wash my own deck before refinishing?
Yes, but only at 1,500–2,000 PSI max for softwoods like pine or cedar. Use a fan-tip nozzle held 12"+ from the surface. Going too close or using too high a PSI will raise the wood grain and require sanding before staining. If you're not sure, our prep service is worth the cost — it's the single biggest determinant of how long a finish lasts.
Does Deck Resurfacing Specialists serve Utah County cities like Provo and Orem?
Yes — we now serve the full Wasatch Front, from Ogden and Logan in the north to St. George in Southern Utah. See our Utah locations page for specific city coverage.
