Deck Repairs & Restoration in Boulder, CO

Common Deck Problems We Repair in Boulder

• ROTTED DECK BOARDS: Wood rot is the #1 deck repair in Boulder. Moisture trapped between boards and joists causes invisible rot that spreads until boards feel soft or break through. We identify all affected boards, check joists for damage, replace rotted wood, and improve drainage to prevent recurrence.

• WARPED AND CRACKED BOARDS: Colorado's dry air and intense sun cause deck boards to cup, twist, and crack. We replace damaged boards with properly acclimated lumber and adjust spacing to accommodate seasonal movement.

• WOBBLY RAILINGS AND LOOSE POSTS: Railing posts loosen over time as wood shrinks and hardware corrodes. This is a safety issue—we reinforce posts, replace corroded hardware, and stabilize railings before someone falls.

• BOUNCY OR SQUEAKY STAIRS: Deck stairs take concentrated loads and wear faster than deck surfaces. We repair stringers, replace treads, and reinforce connections to eliminate bounce and squeaks.

• STRUCTURAL ISSUES: Posts sinking, ledger boards pulling away, joists sagging—these problems affect deck safety. We assess structural issues and make repairs to bring your deck back to code.

Wood Deck vs. Trex & Composite Deck Repair

WOOD DECK REPAIR

Traditional wood decks (cedar, redwood, pressure-treated pine) require more maintenance but are easier to repair. We match wood species and grain, replace individual boards, and refinish to blend with existing surfaces. Wood repairs are typically faster and less expensive than composite.

TREX AND COMPOSITE DECK REPAIR

Trex, TimberTech, and other composite decking materials don't rot but can still be damaged—scratches, stains, mold growth, and fading are common issues. Composite boards can also sag between joists in Boulder's heat. We repair and replace composite decking, source matching colors when possible, and address underlying structural issues that cause sagging.

Deck Repair FAQs

How much does deck repair cost in Boulder?

Most deck repairs cost between $200-$800 depending on scope. Simple board replacements start around $200. Full railing repairs or extensive rot remediation can run $500-$1,500. We charge $120/hour plus materials at cost—no markup, no surprises.

How do I know if my deck needs repair or replacement?

Repair makes sense when damage is limited to surface boards, a section of railing, or a few stairs. If your deck's substructure (joists, ledger board, posts) shows significant rot or the majority of boards are failing, replacement may be more cost-effective. We'll give you an honest assessment.

Can you match new boards to my existing deck?

In most cases, yes. We source matching lumber and can stain new boards to blend with weathered wood. Perfect color matching on older decks isn't always possible, but we get close.

How long does deck staining last in Boulder?

With quality stain and proper application, expect 2-3 years on horizontal surfaces and 3-5 years on vertical surfaces like railings. Boulder's intense sun is tough on finishes. Annual cleaning and resealing high-traffic areas extends the life significantly.

Do you repair composite decks like Trex?

Yes. We repair Trex, TimberTech, and other composite decking materials. While composite doesn't rot, it can warp, fade, and develop mold. Fasteners loosen, and substructures still need maintenance.

When is the best time for deck repair in Boulder?

Spring and fall are ideal—moderate temperatures help stains cure properly. We do repairs year-round, but staining works best when temps are between 50-80°F. Read our guide on deck staining timing.

Beyond Deck Repairs

Your deck is just one part of your home's exterior. We handle fence repairs with the same high-quality craftsmanship—many Boulder homeowners tackle both at once, since decks and fences face the same weather damage. If your deck boards are sound but the finish is failing, our deck staining and sealing services can restore protection and appearance without a complete rebuild. We also provide siding repair for homes where moisture damage has spread from the deck ledger board to adjacent walls—a common issue we catch during deck inspections. For custom built-ins, benches, or pergolas that extend your outdoor living space, our team offers custom carpentry to match your existing deck design. Want to stay ahead of deck problems before they start? Our Proactive Home Maintenance program includes seasonal deck inspections so you catch issues early.
