Wellington Deck Staining and Sealing
Grey, mossy or patchy boards don't have to be replaced. With careful cleaning, proper preparation and the right finish, we restore the colour of your timber deck and give it a protective coat that helps it shrug off Wellington's weather.
Deck Staining and Sealing in Wellington
Unprotected timber has a tough time here. UV breaks down the surface fibres, rain and drizzle soak in and out, and shaded decks grow mould, lichen and moss that turn boards dark and slippery. Left alone, the surface checks and splinters and the boards wear out faster. As fence builders in Wellington who work with outdoor timber every day, we know a good finish is only as good as the preparation underneath it, so that is where we put most of our effort.
We clean, repair and prepare your deck, then apply a penetrating oil or stain chosen to suit your timber, its exposure and the look you're after. The result is a deck that looks cared for, is more pleasant to walk on and is better protected against moisture between coats.

Deck Staining and Sealing Services in Wellington
Protection Against Weather
Rain, wind, salt air and sun all damage unprotected timber, so staining and sealing your deck helps block moisture, reduce cracking and slow fading, extending the life of your decking. Protecting your deck early prevents costly damage much later on.
Thorough Preparation
Good results depend on proper cleaning, sanding and preparation, so we remove dirt, algae and old coatings, creating a clean surface that allows stains and sealers to bond properly. Cleaning and preparing the timber properly helps the finish last longer.
Colour and Finish Options
Choose from natural, tinted and solid-colour products in matte or satin finishes, giving you a deck that complements your home and garden while showing off the timber's character. The right finish can enhance the grain and suit your whole house.
Exterior-Grade Products
We use products designed for New Zealand outdoor conditions, offering durable protection against moisture, UV and wear, helping your deck stay attractive and easier to maintain. Quality products penetrate the timber properly, protecting against moisture, mould and harsh sun damage.
Slip Resistance and Safety
Algae and damp can make decks dangerous, so we can recommend finishes and cleaning methods that improve traction and help keep your deck safer underfoot throughout the year. Regular cleaning and the right finish reduce slippery surfaces, making decks safer.
Maintenance Schedule
We explain how often your deck should be recoated, and how to keep it clean, so you can protect your investment and avoid costly repairs and board replacement later. Regular care is cheaper than major repairs, so we guide you.
Preparation Is Most of the Job
Stain applied over dirt, mould or a flaking old coating won't last. Before any finish goes on, we work through a thorough preparation routine and adjust it to suit the condition of your deck.
Our preparation includes:
- Clearing furniture, pots and debris
- Treating mould, moss and lichen
- Deep cleaning the boards and gaps
- Removing failing or flaking old coatings
- Punching proud nails and tightening screws
- Sanding rough or furry areas
- Flagging boards that need replacing
- Letting the timber dry before coating
Choosing the Right Deck Finish
There is no single best product. The right choice depends on your timber species, how much sun and rain the deck gets, and how often you're happy to recoat. We will recommend a finish and explain why.
Clear and Natural Oils
Soak in and feed the timber while keeping its natural look. They offer less UV protection, so they typically need recoating more often.
Tinted Stains
Add colour and help even out older boards. The pigment improves UV resistance compared with clear finishes.
Solid Colour Stains
Give the most coverage for weathered or mismatched boards, at the cost of hiding the grain. Best for boards with a lot of character to cover.
We generally recommend penetrating products over film-forming coatings on decks. Films can look good at first, but on a surface people walk on they tend to peel and wear unevenly, which makes recoating much harder.
Timing a Deck Finish in Wellington
Finishing a deck depends on the weather more than most outdoor jobs. Timber needs to be dry before coating, and the finish needs dry conditions to cure. In Wellington that means planning around showers, overnight damp and wind that blows dust and leaves onto wet stain.
- We watch the forecast and book dry spells
- We check the timber is dry enough to coat
- We avoid coating in hot direct sun
- We reschedule rather than rush in poor weather
- We advise how long to stay off the deck
- We let you know when furniture can go back
Fences, Steps and Screens Too
If the deck is looking tired, the timber around it often is too. We can treat steps, planter boxes, privacy screens and nearby timber fencing in the same visit, so everything matches. If you're thinking about a new wooden fence to go with a freshly finished deck, we can quote both together.
- Deck stairs and landings
- Timber balustrades and handrails
- Privacy screens and slatted panels
- Pergola posts and beams
- Garden edging and planter boxes
- Timber fencing next to the deck

Deck Staining and Sealing FAQs
It depends on the product, the timber and how exposed the deck is. Sunny, exposed decks and clear finishes need recoating more often than shaded decks with pigmented stain. Water no longer beading on the surface and fading colour are signs it is due.
Some new timber needs time to weather or dry out before it will take a finish well. It depends on the timber and the product. We will tell you when your new deck is ready to coat.
If the old finish is compatible and in fair condition, yes, after a good clean. If it is flaking or a different type of product, it usually needs to come off first so the new coat can bond.
Composite boards generally aren't designed to be stained. We can clean composite decks, and we will focus staining work on any timber parts such as stairs, balustrades and screens.
Drying times vary with the product and the weather. We will give you clear advice on when it is safe to walk on and when furniture can go back on the day.
