What refinishing is

Staining and refinishing that actually lasts.

A good stain job isn't about the stain — it's about what happens before the stain. We pressure wash the whole deck, sand out the rough and splintered spots, strip failed old finish, and only then lay down color and sealer. Skip that prep and the finish peels in a year. That's the difference between a deck that looks good this summer and one that still looks good three summers from now.

We refinish structurally sound decks— wood and composite. If a board is soft, a railing's loose, or the framing's giving out, that's a structural board & railing repair job, not a finish job. And if you're thinking about tearing it out and starting over, that's a new deck build. Staining over a rotting deck is a waste of your money, and we'll tell you that before we quote it.

Scope of work

What deck refinishing includes.

Prep — 70% of the job

  • Pressure/power wash the entire deck surface, railings & stairs
  • Sand rough, raised-grain, and splintered boards smooth
  • Strip failed or peeling old stain and finish
  • Mask and protect siding, trim, and plantings
  • Set popped nails and re-seat loose fasteners
  • Probe every board for soft spots before we commit to a finish

Finish

  • Two coats of premium stain, brushed and back-rolled into the grain
  • Clear or satin sealer for water and weather protection
  • Full railing, baluster, and stair-tread coverage — the spots that get skipped
  • Composite deck deep-clean and brightening (no stain — see below)
  • 24-hour cure before your furniture goes back
  • Final walkthrough so you sign off on the finished deck

Broken boards, loose railings, or soft joists? That's structural board & railing repair — we'll handle that first if your deck needs it.

Deck restoration

From gray and weathered to rich and protected.

Sun and rain turn a wood deck gray, dry, and splintery — but gray doesn't mean gone. Under that weathered surface is good wood waiting to be brought back. We strip away the dead, oxidized layer, sand the boards back to fresh grain, and pull the color back out with a stain matched to your wood and your sun exposure.

The difference is night and day: a deck you were embarrassed to have people over on becomes the reason they come over. And because we seal it properly, the color holds — it doesn't wash out with the first hard rain. Restoration costs a fraction of replacement, and on a structurally sound deck, it's almost always the smarter buy.

Color & opacity

Transparent, semi-transparent, or solid — we help you choose.

There's no single "best" deck stain — there's the right one for your wood, your sun exposure, and how often you want to recoat. Here's the honest tradeoff on each, and we'll help you pick on-site.

Three deck-board stain samples side by side — transparent, semi-transparent, and solid

Transparent / clear

Shows off the wood grain fully and gives the most natural look. It also gives the least UV protection, so the color fades faster and it needs recoating most often — usually every year or two. Best on newer wood or premium species you want to show off.

Semi-transparent

The popular middle. You still see the grain, but you get real pigment doing the UV work, so the color holds longer than clear. It's the go-to for most wood decks in our area — enough protection for full Illinois sun, enough grain to still look like wood.

Solid

Maximum protection and the longest interval between recoats. It hides most of the grain and reads more like a painted finish — exactly what you want on an older deck with mismatched or weathered boards you'd rather even out. The most forgiving on tired wood.

We match opacity to your deck's sun exposure and wood — not whatever's on the shelf.

Brushing stain into deck boards during the Northern Illinois staining season

Timing matters

The Northern Illinois staining season.

Stain and sealer need dry conditions and temperatures above 50°F to cure and bond right. In Northern Illinois, that's roughly late April through early October — and we won't stain outside that window and pretend it'll hold. A finish laid down on a damp deck or in a cold snap will peel, and then you've paid twice.

  • Spring & early summer book up first — schedule your assessment early
  • Late summer & early fall are quieter and just as good for the finish
  • We watch the forecast and won't stain into rain

Know what you have

Wood decks, composite decks — different care.

Real wood (cedar, pressure-treated, hardwoods)

Wood needs to be stained and sealed — that's what protects it from the sun and water that turn it gray and split it. Plan on recoating every 2 to 3 years depending on how much direct sun and rain your deck takes. We can put you on a simple maintenance schedule so it never gets to the "too far gone" stage. Kept up, a wood deck stays rich and protected for decades.

Composite (Trex, TimberTech, Fiberon, AZEK)

You don't stain composite — and anyone who offers to, doesn't know the material. Composite is capped to resist fading, so stain won't bond to it. What it does need is periodic cleaning and brightening to lift off the gray film, mildew, and grime that dull it over time. We deep-clean and brighten composite decks to bring the factory color back. If a board's faded badly or damaged, we can swap it when the brand's still made.

Not sure which you've got? We'll tell you on the assessment — and give you the honest answer on what it actually needs.

Craft over shortcuts

Why homeowners trust us with their deck.

Prep is 70% of the job

Most failed stain jobs failed at prep, not paint. We wash, sand, and strip properly before a drop of stain goes down — because that's what makes it last.

We probe before we quote

Every board gets checked for soft spots. If your deck needs repair before finish, we'll tell you — staining over bad wood wastes your money, and we won't do it.

We match the finish to your deck

Sun exposure, wood species, how often you want to recoat — we help you pick the right opacity for your deck, not the one that's easiest for us.

Premium stains, applied right

Quality semi-transparent, oil/hybrid, and solid acrylic systems, brushed and back-rolled into the grain — not sprayed on and left to sit on the surface.

Honest about the season

We only stain when the weather will let it cure — late April to early October. We won't take your money for a finish that's going to peel.

Written workmanship guarantee

Our labor is backed in writing. If the finish fails on prep we did, we come back and make it right.

No surprises

Straight pricing.

We price deck refinishing by the square foot, and we confirm the number on-site once we've seen the wood and its condition. Here's the honest range so you're not guessing.

Pressure wash + stain + seal (refinish)$2.75–$4.50 / sq ft
Composite deep-clean & brightenQuoted on-site by deck size
Recoat / maintenance visit (existing clients)Discounted per sq ft

Where you land in the range depends on the deck's condition, the opacity you choose, and whether railings and stairs are involved. We confirm the exact number on the assessment — before any work starts.

Maintenance schedule: Real wood does best on a recoat every 2–3 years. Get on a schedule with us and your deck never hits the "too far gone" point — the upkeep coats are faster and cheaper than a full strip-and-refinish down the road.

Coverage & guarantee

When a company's newer, the paperwork matters more, not less. Here's exactly what stands behind our work.

  • General liability — $1M per occurrence / $2M aggregate
  • Certificate of insurance (ACORD 25) available before any job starts
  • Licensed & bonded in Illinois and Wisconsin
  • Workers' comp coverage on every tech
  • Written workmanship guarantee — if the finish fails on our prep, we come back

Deck staining & refinishing FAQs

What's the best time of year to stain a deck in Northern Illinois?
Late April through early October. Stain and sealer need dry conditions and temperatures above 50°F to cure and bond properly, and that's the window we get up here. Spring and early summer book up fastest, so schedule your assessment early. We won't stain outside that window and pretend it'll hold.
How long does deck stain last?
On real wood, expect 2 to 4 years depending on opacity, sun exposure, and how much rain the deck takes. Solid stains last longest, clear finishes the shortest. Composite doesn't get stained at all — it just needs periodic cleaning. We'll set you up on a recoat schedule so it never gets away from you.
What's the difference between staining and sealing a deck?
Stain adds color and UV pigment that shields the wood from sun damage; sealer is the clear layer that blocks water and weather. Most homeowners use the words interchangeably, but they do different jobs — and a good refinish uses both. Stain for the fade, sealer for the rain.
Transparent, semi-transparent, or solid — which stain should I pick?
It depends on your wood and your sun. Transparent shows the most grain but fades fastest and recoats most often. Semi-transparent is the popular middle — real UV protection with the grain still showing. Solid gives the most protection and the longest interval but hides the grain, which is ideal for evening out an older, weathered deck. We help you choose on-site.
Can you stain a composite deck?
No — and be wary of anyone who says yes. Composite (Trex, TimberTech, Fiberon, AZEK) is capped to resist fading, so stain won't bond to it. What composite needs is cleaning and brightening to lift the gray film and mildew and bring the factory color back. We do that, and we can swap a faded or damaged board when the brand's still made.
How much does it cost to stain a deck?
We charge $2.75 to $4.50 per square foot for a full pressure wash, stain, and seal. Where you land depends on the deck's condition, the opacity you choose, and whether railings and stairs are involved — a deck with heavy old finish that needs stripping costs more than a lightly weathered one. We confirm the exact number on-site before any work starts.
Should I just stain my deck myself?
You can — but understand that prep is about 70% of the job, and it's the part most DIY jobs skip. Staining over a deck that wasn't properly washed, sanded, and stripped is why so many home stain jobs peel within a year. If you've got the time and tools to do the prep right, go for it. If not, that's exactly what you're hiring us for.
What ruins a deck stain job?
Staining over a wet or dirty deck, skipping the sanding, choosing the wrong opacity for the sun exposure, painting instead of staining, and putting furniture back before the finish cures. Every one of those shortcuts shows up within a season as peeling, blotching, or fade. We do the unglamorous prep specifically so none of that happens to your deck.
