Most deck restoration in Portland runs $800 to $2,500, depending on deck size and whether you add sanding and staining. A simple clean-and-seal starts near $400, while a full strip, sand, and restain on a large deck reaches $3,000. GreenTree locks the full price in writing first.
Portland sees about 43 inches of rain over roughly 155 wet days a year. As a result, deck boards stay damp, the wood grays, and the old finish fails. Left untreated, that trapped moisture leads to soft, rotting boards.
A deck in the Portland metro takes a beating. UV fades the color in summer, and the long wet season soaks the wood the rest of the year. Once the protective stain wears off, water gets into the grain. Then the boards cup, splinter, and grow the slick green algae that makes a deck dangerous in the rain.
Restoring a deck on schedule is far cheaper than replacing it. For example, a Portland homeowner who cleans and reseals every two to three years keeps the wood sound for decades. By contrast, a neglected deck can rot out in under ten years. A proper restoration also restores traction and removes the trip hazards that come with lifting, splintering boards.
Restoration is more than a wash. Our crew lifts the gray, weathered surface layer, removes the failing old stain, and clears moss and algae from the boards and between them. Then we sand the surface smooth, set any popped nails or screws, and apply a fresh stain or sealer. Finally, the railings and stairs get the same treatment, so the whole structure matches.
From the front of the property to the back, we handle every surface that needs it.
Cedar, fir, and pressure-treated boards cleaned, sanded, and resealed to bring back the grain and color.
The detail work most companies skip. We hand-clean and refinish every rail and spindle to match the deck.
High-traffic, high-slip zones get extra attention so they stay safe and grippy in the rain.
Trex and similar boards soft-washed to lift algae and grime without the harsh scrubbing that voids warranties.
Overhead structures cleaned and sealed alongside the deck so the whole space looks finished.
Lattice and skirting cleared of moss and cobwebs, finishing the look from every angle.
A four-step process that matches the method to the surface, so it comes clean without damage.
First, we inspect the boards, railings, and fasteners. We note rot, loose boards, and how much of the old finish is failing. Then we agree on whether it needs a clean-and-seal or a full strip-and-restain.
Next, we soft-wash the deck to lift gray fibers, moss, and grime, and we strip the failing old stain. Soft washing protects the wood, where high pressure would gouge and fuzz the grain.
We then sand the boards smooth, set popped nails and screws, and spot-treat any rough or splintered areas. As a result, the new finish goes on evenly and the surface is safe underfoot.
Finally, we apply a quality stain or penetrating sealer matched to your wood and color goals. Two coats on the high-wear areas help the finish stand up to {city} weather for years.
deck restoration in Portland typically runs $800 to $2,500 for most decks. A clean-and-seal starts near $400, and a full strip, sand, and restain on a large deck can reach $3,000. The exact figure depends on size, condition, and finish, and GreenTree quotes it all in writing first.
The price of deck restoration in Portland comes down to the deck’s size, its condition, and the finish you choose. A deck that only needs cleaning and sealing costs far less than one that needs a full strip and restain. Either way, the full price is locked in writing before we start.
| Deck Restoration service | Typical Portland price | Notes |
|---|---|---|
| Clean and seal (good condition) | $400 to $900 | Soft wash plus a fresh coat of sealer |
| Clean, light sand, and stain | $900 to $1,800 | Most common, for a deck with worn finish |
| Full strip, sand, and restain | $1,800 to $3,000 | For heavily weathered or neglected decks |
| Railings and stairs (add-on) | $200 to $600 | Detailed refinishing to match the deck |
| Composite deck soft wash | $250 to $600 | Cleaning only, no sealing needed |
| Deck plus fence package | $1,200 to $3,500 | Restore the deck and matching fence together |
For comparison, tearing out and rebuilding a deck costs $30 to $60 per square foot, often $8,000 or more. Restoring it every two to three years protects that investment for a small fraction of the rebuild cost.
Different surfaces need different methods. Here is when each applies.
GreenTree recommends the right level after inspecting your boards, so you never pay for a full restoration a deck does not need, or seal over a surface that should have been stripped first.
Low pressure plus a wood-safe cleaner lifts gray and moss without gouging the grain.
Smooth the boards and knock down splinters so the new finish goes on evenly.
Penetrating, UV-resistant finishes matched to your wood and color goals.
We set popped nails and screws so the deck is safe and the surface is flush.

Most deck restoration in Portland runs $800 to $2,500. A simple clean-and-seal starts near $400, while a full strip, sand, and restain on a large deck can reach $3,000. The figure depends on size, condition, and the finish you choose, and GreenTree locks the full price in writing first. Restoring a deck costs a small fraction of the $8,000-plus a rebuild runs.
Every two to three years in Portland’s wet climate. The 43 inches of annual rain wear the finish faster than in a dry region, and a horizontal surface takes the worst of it. Resealing on schedule keeps water out of the grain and prevents the graying and rot that force a costly rebuild.
Yes. A gray, weathered deck usually needs a full restoration rather than a simple seal. We strip the dead finish, sand the boards smooth to bring back fresh wood, then apply new stain. As long as the structure and boards are sound, restoration brings back the look of new wood. If any boards have rotted through, we will point those out at the quote.
High pressure will. A pressure washer on full power gouges soft wood, raises the grain, and leaves fuzzy, splintered boards. That is why we soft-wash decks, using low pressure and a wood-safe cleaner to lift gray and moss, then sand for a smooth finish. The result is clean wood without the damage a careless pressure wash causes.
Both, and we recommend the right level after inspecting the deck. Cleaning alone refreshes the look but leaves the wood unprotected. Sealing or staining after cleaning is what actually protects the boards from Portland moisture and UV. We carry quality stains and sealers and apply them as part of a full restoration.
Late spring through early fall, when there is a stretch of dry, mild weather. Stain and sealer need a dry surface and a dry window to cure, which is harder to find in the wet Portland winter. We watch the forecast and schedule the staining stage for a dry run so the finish bonds properly.
Yes. Composite and PVC decking does not need sealing, but it does grow algae and collect grime in Portland’s damp climate. We soft-wash it with a cleaner safe for composite, which lifts the green and dirt without the harsh scrubbing that can void the manufacturer warranty. It comes out looking close to new.
A clean-and-seal on an average Portland deck is often a single day. A full strip, sand, and restain usually takes two to three days, since the staining stage needs the wood dry first. We give you a clear schedule when we lock the quote and work around the weather for the finish coat.
Yes. Railings, balusters, and stairs are part of a proper restoration, and skipping them leaves a deck looking half-done. We hand-clean and refinish every rail and spindle to match the deck boards. Stairs get extra attention because they are the highest-traffic, highest-slip part of the structure.
A film of algae and mildew builds up on damp deck boards, and it turns dangerously slick when wet. Portland’s 155 rainy days a year give it plenty of time to grow. A restoration removes that growth down to clean wood and a fresh finish, which restores traction and removes the slip hazard for the season.
Yes. GreenTree is Oregon-registered and carries $2M in general liability coverage plus workers compensation, with documents available on request. That protects your home if anything goes wrong during the work, and it meets the vendor requirements most Portland HOAs and property managers set.
Restore, by a wide margin, as long as the structure is sound. A Portland deck restoration runs $800 to $2,500, while a full tear-out and rebuild costs $8,000 or more. Restoring every two to three years keeps the wood healthy and pushes a rebuild decades down the road. We will tell you honestly if a deck is too far gone to save.
