Don't Ignore Deck Rot

A small soft spot today can become a structural failure in one season. In the St. Louis climate, freeze-thaw cycles accelerate wood rot rapidly. Early repair costs a fraction of full replacement.

What Homeowners Are Saying

4.9 average · 127+ reviews

"Our deck had severe rot damage. Hero Handyman replaced the damaged joists and boards for $2,800 — far less than the $15,000 replacement quote we got elsewhere."

— Mark T., Edwardsville IL

"Deck boards were soft and the railing was wobbly. They assessed the whole structure, replaced what needed replacing, and didn't try to upsell me. Fair pricing, great result."

— Chris B., O'Fallon IL

"Failed a home inspection for loose railings. Hero Handyman came out next day, fixed everything, and we closed on time. Lifesavers."

— Sarah L., St. Louis MO

Deck Repair FAQs

Common questions from St. Louis and Metro East homeowners about deck repair.

If less than 30% of the structure is damaged, repair is almost always more cost-effective. Warning signs that repair is needed: soft or spongy boards, loose railings, visible rot, large cracks, and wobbly posts. If the ledger board or more than half the joists are rotted, replacement may be the better investment. We'll give you an honest assessment during our free inspection.
Board replacements and railing repairs typically take 1 day. Structural repairs or full resurfacing take 2–4 days. We'll give you a firm timeline before we start so you can plan accordingly.
Simple board replacements start around $50–$150 per board. Railing repairs run $300–$800 per section. Full deck resurfacing ranges from $1,500–$4,500 depending on deck size. Structural repairs vary widely based on the extent of rot. We provide a detailed written estimate before any work begins.
We primarily use pressure-treated pine (ACQ or CA-C treated) for structural members and decking boards — the industry standard for outdoor use in the St. Louis climate. We can also work with cedar, redwood, or composite decking if you prefer to match your existing material or upgrade.
We do our best to match your existing decking material in species, profile, and dimension. Exact color matches are difficult with weathered wood, but we can stain or seal the new boards to blend. For a fully uniform look, we can resurface the entire deck at the same time.
Spring and fall are ideal — moderate temperatures help lumber and sealants cure properly. However, we perform deck repairs year-round in St. Louis. If your deck has safety concerns (loose railings, soft boards), don't wait for the right season — call us now.
Yes. We repair and replace composite decking boards from most major brands including Trex, TimberTech, and Fiberon. We'll source matching materials when possible, or recommend the closest available option.
Absolutely — this is one of our most common calls. We can repair specific items flagged in a home inspection report (loose railings, rotted boards, improper ledger attachment) quickly, often within 1–2 days, to help keep your real estate transaction on track.
