We fix loose boards, rotting frames, failing stairs, and unsafe rails. Our team inspects every piece of your structure, then recommends what’s worth keeping and what needs replacement. We restore decks to full code compliance—and make them look great again.
Deck problems don’t always require demolition. We check post depth, joist condition, ledger integrity, and stair safety. If your base is solid, we’ll reinforce and reframe instead of starting over. You get a safe, long-lasting deck at a fraction of the cost.

You shouldn’t have to guess what’s wrong with your deck. We inspect posts, joists, beams, fasteners, stairs, and railings—then give you a written repair plan. We’ll tell you what’s safe, what’s borderline, and what needs to go. That way, you can make informed choices.

We reinforce aging decks with new joists, beams, braces, and posts—leaving the good structure in place while correcting weak points. It’s ideal for decks that have shifted, warped, or started to rot but don’t need full replacement. Safe, fast, and budget-conscious.
We replace worn decking with new boards—composite or wood—while keeping your frame if it’s up to code. We also swap out unstable stairs, rebuild handrails, and secure ledgers to bring everything back into safe condition. It’s a fresh start for your existing setup.

Lower Cost: Reinforcing your frame saves money versus total replacement.
Preserve What Works: We keep the safe structure and replace only what’s necessary.
Code-Ready Results: Your repaired deck meets today’s safety and building standards.
Fresh Look Without Starting Over: New stairs, rails, and boards give your deck a total refresh.
Don't worry, we can help!
Rotten boards, soft stairs, wobbly rails, or sinking posts are all signs your deck needs attention. Whether it’s moisture, age, or old construction, we’ll assess the cause and create a plan to fix it safely—so you can enjoy your space without worrying.

Rain causes rot. Heat warps boards. Freeze-thaw cycles shift posts and stairs. Over time, even well-built decks can fail. We repair weather damage with pressure-treated materials, smart drainage, and framing that resists movement—so your deck can keep up.
If your deck feels unsafe or looks worn out, don’t guess—get answers. Here are the most frequent questions we get about repair vs. rebuild, material lifespan, and what it really takes to restore a deck the right way.
We inspect the frame, posts, stairs, and railings to assess whether repairs can bring it back to full safety and code.
Yes—if the frame passes inspection. Re-decking over a solid frame is a great cost-saving option.
We’ll get the closest match available and can replace additional boards for a seamless look if needed.
Often yes. Composite adds durability and low maintenance—especially if we’re already replacing the surface.
