Experienced Fence Builders in Idaho Falls, ID 83401 - Custom Decks & Fencing

The main cause is our dramatic freeze-thaw cycles. Moisture gets into the wood, then freezes and expands, causing warping, cracking, and splitting. A sign of this is boards that look cupped or have large cracks. The solution is to replace damaged boards with pressure-treated or composite lumber, and ensure proper spacing for drainage. Custom Decks & Fencing can inspect your deck, identify problem areas, and perform targeted repairs or full replacements as needed.

Key signs include widespread rot, loose railings, or nails popping up. If the structural posts or beams are compromised, a repair may not be safe. In Idaho Falls, where snow loads are heavy, a failing deck is a safety hazard. Our team assesses the entire structure—joists, ledger board, and footings. If more than 30% of the deck is damaged, replacement is often more cost-effective and safer. We’ll give you an honest recommendation based on what we find.

For durability, we recommend composite decking like Trex or TimberTech. They resist moisture, won’t warp or splinter, and require minimal maintenance. If you prefer wood, pressure-treated pine is affordable but needs annual sealing to fight our freeze-thaw damage. For a premium option, cedar or redwood naturally resist rot. We’ll help you choose based on your budget and how much upkeep you want. Every deck we build is designed to handle our local climate.
