Deck Repair Services We Provide
Illinois and Missouri winters are hard on decks. Freeze-thaw cycles, moisture, and UV exposure cause boards to rot, fasteners to loosen, and railings to wobble. We fix all of it — before small problems become expensive full replacements.
Deck Board Replacement
Rotted, cracked, splintering, or soft deck boards are a safety hazard and an eyesore. We remove damaged boards and replace them with pressure-treated lumber or composite decking that matches your existing deck as closely as possible. The St. Louis region's humid summers and cold winters accelerate wood decay — especially on decks that don't get regular sealing.
Railing Repair & Replacement
Wobbly railings are a serious fall hazard, especially for children and elderly family members. We tighten, re-secure, or replace railing posts, balusters, and top rails to bring your deck up to safe, code-compliant standards. Illinois and Missouri building codes require deck railings to withstand 200 lbs of lateral force — we make sure yours can handle it.
Structural Deck Repair
Rotted joists, failing ledger boards, and compromised posts are the most serious deck problems — and the most dangerous if ignored. We assess structural integrity, replace compromised framing members, and ensure your deck is safe to use. We give honest assessments: if a deck is beyond repair, we'll tell you upfront.
Stair & Step Repair
Deck stairs take more abuse than any other part of the structure. Loose stringers, rotted treads, and wobbly handrails are common after a few Illinois winters. We repair or replace deck stairs to restore safe, solid footing — whether it's a single step or a full staircase.
Ledger Board Repair
The ledger board is where your deck attaches to your house — the most critical structural connection. A failing ledger can cause the entire deck to pull away from the home. We inspect, reinforce, or replace ledger boards and ensure proper flashing to prevent water intrusion behind the board.
Deck Maintenance & Sealing
Annual deck maintenance is the best way to avoid costly repairs. We handle cleaning, re-fastening loose boards, replacing isolated rotted sections, and applying sealant or stain to protect against moisture and UV damage. A well-maintained deck can last 20–30 years. A neglected one often needs full replacement within 10.
Signs Your Deck Needs Repair
Most deck problems start small and get worse with every season. A single rotted board leads to moisture spreading to the joists. A loose railing post becomes a fall hazard. Catching these issues early is the difference between a $300 repair and a $10,000 replacement.

Why Deck Repair Is Worth Doing Right
A deck is one of the most-used outdoor spaces in a home — and one of the most dangerous when it's in poor condition. Deck collapses and railing failures cause thousands of injuries every year in the U.S.
Beyond safety, a well-maintained deck adds real value to your home. A rotted or structurally compromised deck is a red flag during home inspections and can derail a sale or force a price reduction.
We've repaired hundreds of decks across the St. Louis metro area. We know what holds up in this climate, what corners get cut during original construction, and how to fix it properly the first time.
