What Is Professional Deck Repair?

Deck repair is often the critical first step before deck restoration. You can’t sand and oil a deck that has rotten boards, structural issues, or damaged timber—the problems need to be fixed first.

Professional deck repair means identifying the root cause (not just the symptom), replacing damaged boards correctly, allowing new timber to weather properly, then using our sanding and chemical prep process to blend everything seamlessly. It’s not just about swapping boards—it’s about making new timber marry with old timber so you can’t tell the difference.

Our Approach: Specialists in Restoration, Not Full Carpentry

We’re specialists in the restoration and ongoing maintenance of decking. Here’s how we handle repairs:

Board Replacements (Up to 12 Boards)

We handle board replacements for jobs involving up to 12 boards. This typically covers:

• Rotten or split boards
• Boards damaged by termites or water
• Boards removed for spa removal or equipment access
• Small deck extensions or modifications
• Balustrade repairs
• Stair tread replacements

We carry the tooling needed for board replacement as part of our restoration workflow. It makes sense logistically—we’re already on-site with sanding equipment, and board replacement integrates naturally into our process.

Larger Carpentry Jobs (12+ Boards)

For jobs beyond 12 boards or significant structural work, we refer in trusted carpenters we’ve worked with for years. Here’s why:

Due to the amount of tooling we carry for our sanding, sealing, and repairs, it doesn’t logistically make sense to double up with full carpentry gear. Our vans are optimized for restoration work—belt sanders, orbital sanders, dust extractors, chemical treatments, oils, applicators.

Bringing full carpentry equipment (table saws, nail guns, framing tools) for large structural jobs would mean a separate van, separate crew, separate day—it’s more efficient to bring in a carpentry specialist while we focus on what we do best: making your deck look brand new.

The Perfect Workflow: Carpenter First, Us Second

It’s also great to have carpenters come through to conduct any sub-floor repairs before our wave of works. This way:

1. Carpenters fix structural issues (joists, bearers, stumps)
2. Carpenters replace boards (if more than 12 needed)
3. New timber weathers for 8-12 weeks
4. We come in with our tailored sanding and chemical prep process
5. We blend new boards with old using our 9-step restoration process
6. If needed, we apply custom pigmented oils to new boards to chase continuity between new vs old

This workflow ensures any breakages or replaced boards get pulled together seamlessly. You end up with a deck that looks completely uniform—no visible difference between new and old timber.

Why New Boards Need to Weather (8-12 Weeks)

This is critical and something most companies don’t tell you:

Generally speaking, when boards are replaced, we recommend that the timbers are left to weather for a good 8-12 weeks before we restore the entire deck. Here’s why:

Tannin Leeching

New timber (especially Merbau, jarrah, spotted gum) has natural oils and tannins that need to leech out. If you sand and oil too soon, the tannins will bleed through the finish and create dark streaks within weeks.

Timber Movement

New boards expand and contract as they acclimatize to Melbourne’s weather. If you sand and oil before they’ve settled, you’ll get cupping and gaps appearing after the finish is applied.

Colour Matching

Fresh-cut timber is much lighter than weathered timber. After 8-12 weeks of weathering (sun, rain, moisture cycles), new boards darken and move closer to the colour of your existing deck. This makes it much easier for us to blend them using our sanding and custom-tinted oils.

How to Speed Up Weathering

Hose down the new boards once a week to accelerate tannin leeching. This can reduce the weathering period from 12 weeks to 8 weeks.

Common Deck Repair Scenarios

Spa Removal Board Replacement

You’ve had a spa removed and now there’s a rectangular patch of missing or newer boards. We recommend:

1. Carpenter replaces boards (or we do if it’s under 12 boards)
2. New boards weather for 8-12 weeks
3. We restore the entire deck using our 9-step process
4. We apply custom pigmented oils to the new boards to match the old
5. Result: Seamless deck with no visible spa footprint

Deck Extension Blending

You’ve extended your deck and need the new section to blend with the old. Same process:

1. Carpenter builds extension (if large) or we handle board work (if small)
2. New timber weathers 8-12 weeks
3. We restore the entire deck (old + new)
4. Our sanding process brings both sections to fresh timber
5. Custom-tinted oils ensure colour continuity
6. Result: One uniform deck, no visible join line

Rotten Board Replacement

You’ve got 3-8 rotten boards scattered across the deck. We handle this:

1. We replace the boards (under 12 = within our scope)
2. New boards weather 8-12 weeks
3. We restore entire deck
4. Sanding removes the weathered grey from old boards and tannins from new
5. Result: Everything looks fresh and uniform

Sub-Floor Structural Repairs

You have rotten joists, bearers, or stumps. This needs a carpenter first:

1. We refer you to our trusted carpenter network
2. Carpenter fixes structural issues and replaces any damaged boards
3. New timber weathers 8-12 weeks
4. We come in and restore the entire deck surface
5. Result: Structurally sound deck with a like-new surface

Our Repair & Restoration Process

When repairs are combined with restoration, here’s our complete workflow:

Step 1: Assessment & Board Replacement

We identify damaged boards, replace up to 12 (or refer carpenter for larger jobs), countersink all fixings.

Step 2: Weathering Period

New boards weather for 8-12 weeks (you can hose weekly to accelerate tannin leeching).

Step 3: Decupping & Levelling Sand

We fix cupped, warped boards across the entire deck using 5 waves of sanding. New boards and old boards are brought to the same level—no trip hazards, no uneven surfaces.

Step 4: Full Deck Sanding

We sand the entire deck back to fresh timber. This removes the grey from old boards and the surface tannins from new boards, bringing everything to a uniform fresh-timber appearance.

Step 5: Deep Degrease

Our proprietary treatment pulls remaining tannins, oils, and contaminants from both old and new timber.

Step 6: Orbital Scrub Treatment

Power scrubbing ensures all timber (new and old) has completely open pores for maximum oil penetration.

Step 7: Fine Sand Finish

Second sand creates smooth, uniform grain across the entire deck surface.

Step 8: Timber Brightening

Brightening balances colour tones across old and new timber, prepping for oil.

Step 9: Custom-Tinted Oiling

This is where the magic happens. More often than not, we end up applying custom pigmented oils to the new boards to chase continuity between new vs old.

If the old timber is weathered darker, we’ll apply a slightly stronger pigment to the new boards on the first coat to bring them closer in tone. Then we apply a uniform second coat across everything.

Result: You can’t tell which boards were replaced. It all looks like one uniform, freshly restored deck.

Frequently Asked Questions

Can you handle structural repairs like rotten joists?

For significant structural work, we refer trusted carpenters. It’s more efficient to have a carpentry specialist handle sub-floor repairs, then we come in afterward for the restoration phase. This ensures you get expert work at both stages.

Why do new boards need to weather for 8-12 weeks?

New timber has natural oils (tannins) that need to leech out. If you sand and oil too soon, tannins bleed through the finish within weeks. New boards also need to acclimatize to Melbourne’s weather—they expand, contract, and settle. Weathering for 8-12 weeks ensures stability before we restore.

Can you match new boards to old boards?

Yes—this is our specialty. After the weathering period, we sand the entire deck back to fresh timber (old and new). Then we use custom-tinted oils to chase continuity between new vs old. More often than not, we apply slightly stronger pigment to new boards on the first coat to bring them closer in tone to aged timber. Result: seamless blending.

What if I’ve had a spa removed and need boards replaced?

We handle this regularly. We replace the missing boards (if under 12), let them weather 8-12 weeks (you can hose weekly to speed tannin leeching), then restore the entire deck. Our process makes the spa footprint completely invisible.

Do you replace balustrades and stairs?

Yes, for repairs and replacements within our scope (individual balustrades, handrails, stair treads). For full balustrade rebuilds or significant stair structural work, we refer carpenters.

Can you restore a deck that’s had boards replaced by someone else?

Absolutely. As long as the boards have weathered for 8-12 weeks, we can restore the entire deck and blend the new boards seamlessly with our sanding and custom-tinted oils.
