Community Tips
Replace corroded fasteners with corrosion-resistant deck screws rather than re-tightening original bolts, as rust weakens structural integrity even when boards feel snug—Spax Stainless Steel Deck Screws ($12-18 per box) prevent the galvanic corrosion that causes premature board failure in 3-5 years.
Never overtighten railing posts with structural screws, as this compresses wood fibers and creates stress points that crack under lateral load—tighten until snug resistance is felt, then add only one-quarter turn to avoid damage that compromises safety certification.
Budget $150-300 for a full deck board and railing refresh using quality fasteners like GRK RSS Plus Structural Screws ($25-35 per box of 50), which costs significantly more upfront than standard hardware but eliminates the need for repeat repairs every 2-3 seasons. ---
