Your deck looks rough.

A few boards are cracked. The stain disappeared sometime during the Obama administration. One railing has a little more personality than you'd like. And there's a spot near the stairs you've started instinctively stepping over.

So naturally:

Do I repair the deck or replace the whole damn thing?

Maybe neither extreme.

A deck doesn't need to look new to be good.

And a fresh coat of stain doesn't make a bad deck safe.

The question isn't:

How ugly is it?

The question is:

What's happening underneath you?

Because deck boards are the part you see.

The structure is the part keeping you out of the emergency room.

FIRST: A WEATHERED DECK ISN'T NECESSARILY A BAD DECK

Utah is brutal on exposed wood.

Salt Lake's climate gives your deck hot, dry summers, intense sun, snow, freezing temperatures and seasonal moisture changes. Utah State University describes Utah as having a semi-arid climate with hot, dry summers and cold, snowy winters.

Over time, exterior wood can:

• fade

• dry out

• split

• check

• warp

• cup

• lose its finish

• develop small surface cracks

None of those things, individually, means:

DECK DEAD.

If the structure underneath remains sound, an ugly deck may simply need repairs, maintenance and refinishing.

I own sunglasses.

I'm capable of looking past appearances.

START WITH THE STRUCTURE, NOT THE DECK BOARDS

When homeowners inspect a deck, they naturally look down.

I want you to look under.

A typical wood deck is a system.

You've got:

footings and posts supporting it,

beams carrying the load,

joists supporting the decking,

a ledger connecting many attached decks to the house,

then the deck boards, stairs and railings you actually interact with.

If the deck boards are tired but the structural system is healthy?

That's potentially a repair project.

If the boards look beautiful but the structure underneath is deteriorating?

Congratulations on your extremely attractive problem.

REPAIR THE DECK IF A FEW BOARDS ARE BAD

This is the easy one.

If you've got:

three split boards,

one warped board,

a board with localized rot,

or a couple boards that have reached the end of their useful lives—

replace the boards.

You don't throw away the motorcycle because it needs a tire.

Localized surface damage is exactly what deck repair is for.

But whenever I replace a damaged board, I want to know:

Why did this board fail?

Age?

Water?

Bad fasteners?

Poor drainage?

Something trapping moisture?

If we don't answer that, we're just installing a nicer future problem.

REPAIR IT IF THE FASTENERS ARE THE PROBLEM

Deck screws and nails have a surprisingly dramatic existence.

Over time you may find:

raised fasteners

loose boards

corroded hardware

missing screws

connections that have loosened

Sometimes the wood itself is perfectly serviceable.

The connections need attention.

This is why walking your deck slowly once or twice a year is useful.

If something moves that didn't move last year:

Investigate it.

Decks aren't supposed to develop new dance moves.

REPAIR IT IF THE RAILING IS LOOSE—BUT FIND OUT WHY

A loose railing doesn't automatically condemn the entire deck.

It does, however, deserve attention.

Immediately.

Railings are not decorative suggestions.

People lean on them.

Children grab them.

Your uncle will absolutely put his entire body weight against one while holding a beer.

Figure out whether the problem is:

loose hardware,

a damaged rail,

a failing post,

deteriorated wood,

or a larger structural issue.

Then fix the cause.

Don't just drive another screw into something rotten and announce:

“She's solid.”

She may not be.

REPAIR IT IF THE STAIRS HAVE AN ISOLATED PROBLEM

Deck stairs take abuse.

People.

Dogs.

Snow.

Water.

Ice.

Repeated foot traffic.

They can develop problems before the rest of the deck.

A loose tread, isolated damaged board or failed piece of hardware may be repairable.

But if the:

stringers are deteriorating,

stairs are pulling away,

supports are failing,

or the entire stair assembly feels unstable—

we're past cosmetic handyman territory.

Stairs are one of the places where I have essentially zero interest in optimism.

WHEN SHOULD YOU REPLACE THE DECK?

Now we get underneath it.

REPLACE IT WHEN STRUCTURAL ROT IS WIDESPREAD

This is the big one.

If significant deterioration affects multiple structural components—posts, beams, joists or other critical members—the economics and safety calculation changes.

One localized damaged component may be repairable.

Widespread structural deterioration?

You're not preserving a deck anymore.

You're systematically replacing a deck while pretending you aren't.

At some point, starting over is smarter.

PAY ATTENTION TO THE LEDGER

If your deck is attached to your house, the connection between the two matters enormously.

The International Residential Code contains detailed requirements for deck ledger connections, fasteners, flashing and lateral load connections because failure at the house connection can have serious consequences. Salt Lake City currently uses adopted building codes based on the 2021 International Residential Code with Utah amendments.

Translation:

That board against your house isn't just another piece of lumber.

If you see:

water damage,

significant deterioration,

movement,

missing or questionable connections,

or anything about the house-to-deck connection that concerns you—

have it properly evaluated.

This is not where we deploy the:

“Eh, probably fine.”

method.

REPLACE IT WHEN THE POSTS & SUPPORTS ARE FAILING

Walk underneath if you can safely access it.

Look at the posts.

Especially near the bottoms.

Do you see:

rot,

splitting,

significant deterioration,

movement,

questionable connections,

or supports that appear to be shifting?

One isolated problem may have a repair solution.

Multiple failing supports are telling you something.

Listen.

Your deck is literally standing on these things.

REPLACE IT WHEN YOU'RE CONSTANTLY REPAIRING IT

This is the economic test.

Last year:

three boards.

This year:

two joists and a stair.

Next year:

another post.

Then the railing.

Then six more boards.

At some point you've entered a subscription service.

Deck+

$399 every spring for the rest of your natural life.

There comes a point where repeated repairs stop being preservation and become installments on the replacement you should have done earlier.

Look at the whole system, not just today's broken component.

WHAT ABOUT RESURFACING THE DECK?

This can be a great middle ground.

If the underlying structure is sound but the decking itself is worn out, replacing the deck boards while retaining a healthy structure may make sense.

That's very different from rebuilding everything.

This is also where some homeowners consider changing the decking material.

You might retain appropriate structural components and install new wood or another compatible decking product.

But—and this is important—

don't put expensive new decking over a questionable old structure.

That's like putting leather pants on a corpse.

Stylish.

Still a corpse.

CAN I JUST STAIN IT?

Maybe.

If the issue is primarily:

fading,

surface weathering,

loss of finish,

or cosmetic aging—

cleaning and refinishing may be exactly what it needs.

But stain is not:

wood filler,

structural reinforcement,

rot treatment,

joist repair,

or divine intervention.

If you can push a screwdriver into deteriorated wood, I'm not interested in discussing which shade of cedar you prefer yet.

HOW DO I CHECK FOR WOOD ROT?

You don't need to start stabbing your deck indiscriminately.

Look first.

Potential warning signs include:

soft wood

crumbly areas

deep cracking associated with deterioration

discoloration

fungal growth

wood that easily gives way under gentle probing

Pay particular attention to areas where moisture can linger:

around connections,

near the house,

around stairs,

beneath planters,

at post bases,

and anywhere debris accumulates.

If you're not sure what you're looking at, that's fine.

That's what inspections are for.

You don't have to diagnose the deck yourself.

You just have to notice when something looks wrong.

YOUR FLOWER POTS MAY BE SECRETLY TERRIBLE

I like plants.

I do not like large planters sitting directly against wood for seventeen consecutive years.

Anything that repeatedly traps moisture or debris against the decking can create localized deterioration.

Move things occasionally.

Look underneath.

Same goes for:

outdoor rugs,

storage boxes,

furniture that never moves,

and whatever enormous object you've decided is simply part of the deck now.

Your deck needs to dry.

Let it.

WHAT ABOUT SNOW?

Snow itself isn't automatically a death sentence for a properly designed deck.

But winter exposes weaknesses.

Water gets into cracks and vulnerable areas.

Temperatures change.

Snow and ice sit on surfaces.

And if the deck already has deteriorated components, winter isn't going to improve them.

Utah State University specifically discusses freeze-thaw cycles as a concern for outdoor materials in Utah's climate.

That's why I like inspecting decks in spring.

Winter has just finished submitting its performance review.

Read it.

DOES MY SALT LAKE CITY DECK NEED A PERMIT?

Potentially.

Salt Lake City's building-services guidance requires permits for many construction projects and directs homeowners to determine applicable requirements before beginning work. Deck requirements can depend on factors including the scope, height, attachment and type of work being performed.

A few replacement deck boards are obviously a different project from demolishing and rebuilding an elevated attached deck.

If you're doing substantial deck construction or replacement, check the requirements for your jurisdiction before work begins.

And remember:

Salt Lake City rules apply in Salt Lake City.

If you're in Millcreek, Murray, Sandy, West Jordan, Holladay, Draper or elsewhere, check with your municipality.

Your ZIP code can change the answer.

WHAT ABOUT UTAH'S HANDYMAN RULES?

The scope and value of the project matter.

Utah regulates contractor activity while providing a handyman exemption for qualifying work under specified conditions. Larger projects and certain regulated work may require appropriately licensed contractors regardless of whether somebody casually calls the project “deck repair.”

That's why I look at the project before promising anything.

Replacing several boards?

Potentially straightforward handyman territory.

Rebuilding a substantial elevated deck?

Different conversation.

The phrase “I own a circular saw” is not a Utah contractor classification.

DECK REPAIR VS. REPLACEMENT: THE BRADLEY TEST

Here's the simplified version.

REPAIR IT WHEN:

The underlying structure is sound.

Damage is localized.

Only a few deck boards need replacement.

A railing has a repairable issue.

Hardware or fasteners need attention.

The stairs have an isolated problem.

The deck mainly needs maintenance or refinishing.

You still have a fundamentally good deck.

CONSIDER RESURFACING WHEN:

The structure is sound.

But a large portion of the decking has reached the end of its life.

Keep the good skeleton. Replace the worn surface.

REPLACE IT WHEN:

Structural rot is widespread.

Multiple posts or supports are failing.

Joists or beams have significant deterioration.

The house connection is compromised.

The deck moves substantially.

Repairs keep multiplying.

Or you're about to spend a small fortune preserving something that is structurally asking to retire.

At that point, let it retire.

THE MOST IMPORTANT TEST ISN'T VISUAL.

Stand on the deck.

Walk around.

Without doing anything stupid, pay attention.

Does it feel:

solid?

Do the railings feel secure?

Do the stairs feel stable?

Does anything noticeably move?

Bounce?

Shift?

Sag?

A deck should feel boring.

Boring is excellent.

I don't want an immersive experience.

I don't want character.

I don't want your deck expressing itself.

I want you to walk onto it carrying a drink and completely forget that structural engineering exists.

That's a successful deck.

DON'T REPLACE A GOOD DECK BECAUSE IT LOOKS OLD.

And don't keep a bad deck because it photographs well.

That's the entire philosophy.

I've got no interest in selling somebody a full replacement because their boards turned gray.

I've also got no interest in staining a structurally questionable deck and pretending we accomplished something.

Repair what's worth saving.

Resurface what's structurally good but worn out.

Replace what's actually done.

Your deck doesn't care which option costs less.

Physics gets the deciding vote.

NOT SURE WHAT YOUR DECK NEEDS?

Send me pictures.

I want:

one photo of the entire deck

one underneath the deck

the posts near ground level

the joists and beams

where the deck meets the house

the stairs

the railings

and close-ups of anything making you nervous.

Tell me where you are in the Salt Lake Valley and what you've noticed.

If it's repairable handyman territory, I'll tell you.

If what you actually need is a larger appropriately licensed deck contractor, I'll tell you that too.
