8 Best Decking Contractors in Singapore (July 2026)

Before you compare contractors, settle the material, because it changes the price, the upkeep and who you should even be calling. There are three broad families for a Singapore deck, plus aluminium as a niche option, and they are not interchangeable.

Composite and WPC (wood plastic composite) are the default for most balconies and condos now, and for good reason. The boards are a blend of recycled plastic and wood fibre, so they are termite proof, splinter free and do not need the yearly oiling that real timber demands. They shrug off rain, sun and humidity, which is exactly what you want here, and a rinse with water keeps them looking new. The trade off is that a dark composite board can get hot underfoot in direct afternoon sun, and the very cheapest uncapped boards can fade, so the capped (cWPC) versions from a good brand are worth the extra.

Natural hardwoods are the choice when you want real timber warmth and grain. Chengal is the most durable hardwood commonly used here, naturally resistant to decay and moisture, and it is the classic Singapore decking wood. Balau and Merbau are the dense, dependable mid options, both resistant to rot and insects. The catch with all natural timber is maintenance: it greys and needs periodic sanding and re-oiling to keep its colour, so you are trading low upkeep for the look and feel of the real thing. Accoya is the premium step, a modified softwood that barely shrinks or swells and resists rot exceptionally well, so it behaves like a stable hardwood while taking a stain beautifully. Aluminium decking exists for rooftops and fire-rated situations where zero rot and low weight matter most, but it is a niche buy rather than a home default.

One more thing to settle upfront, and it is the one most people skip: what happens under the deck. On a balcony or terrace the boards sit on a substructure of joists, usually aluminium or treated timber, raised on adjustable pedestals so water can drain away underneath. In our climate that drainage layer and the waterproofing membrane below it are what keep the space dry and the frame sound. A deck is only as good as the frame and drainage you cannot see, so make that part of the conversation, not an afterthought.

Tulou is the one I would point most people to first for a premium composite deck done properly. It is one of the most established composite timber decking specialists in Singapore, with over a decade of experience and more than 300 projects across homes and commercial developments, and it brings in premium composite boards from the United States under its CULTURE and TUWOOD lines rather than the generic imports many shops stock.

What I like is the all-in accountability. Tulou backs the deck with a 12 year comprehensive warranty that covers the composite board, the aluminium substructure and the workmanship together, which is a genuinely strong stance in a trade where the frame and the drainage are where things quietly go wrong. It handles balconies, patios, planters and swimming pool decks, and the capped WPC boards are made to stay cooler and hold their colour under our sun. If you want a specialist who lives and breathes composite and stands behind the whole build, Tulou is a strong starting point.

Evorich is the household composite name, and its evoDECK line is the one many families land on for a balcony or poolside deck. Evorich has spent years as one of the bigger movers in the floors, deck and walls space here, and evoDECK is a wood plastic composite made partly from recycled plastic bottles and reclaimed wood fibre, so it carries an eco angle alongside the performance pitch.

The product is built for exactly the areas homeowners worry about: balconies, swimming pool surrounds and planter boxes. It resists moisture, termites and mould, has an anti-slip surface for safer walking when wet, and, unlike real timber, never needs yearly refinishing, so a rinse keeps it looking fresh. Evorich sits in the mid to high end of the composite market, so it is not the cheapest, but for a brand with a long track record, a proper showroom and nationwide installation, it is an easy shortlist entry for a low-maintenance outdoor deck.

If you want a contractor with deep timber roots and a design-and-build approach, Nam Soon is where I would start. Incorporated in 1986, it grew from a sawmiller and timber trader into a market-leading outdoor timber design-and-build specialist, and that heritage shows in how it talks about wood. It is now a second-generation family business, which tends to mean the knowledge and the accountability sit in the same place.

The range spans both worlds: Softline Merbau natural timber decking for people who want real wood, and its own ENV-Shield WPC composite for those who want the low-maintenance route, so it can steer you honestly between the two rather than pushing the only thing it stocks. It also runs a TimberMedic aftercare programme for ongoing maintenance, which matters more than people expect with a natural timber deck. With a 4.9-star rating across its reviews, Nam Soon is my pick for a design-led outdoor deck from a genuine timber house.

If your heart is set on real hardwood rather than composite, The Woodcrafters is the specialist I would flag first. It is a genuine timber house that works across interior and exterior installations, and for decking it leans into the two woods that suit our outdoors best: Chengal, the classic durable Singapore decking hardwood, and Accoya, the premium modified wood prized for its exceptional dimensional stability in a humid climate.

That focus is the draw. Chengal gives you the traditional, hard-wearing timber deck that ages into a natural silver-grey if you let it, while Accoya is the answer for anyone who has been burned by timber that warps and wants a real wood surface that stays put and holds a stain. Because the same team handles flooring, cladding, staircases and trellises in timber, they understand grain, finishing and outdoor detailing at a level a general decking shop rarely matches. For a considered natural-wood deck, The Woodcrafters earns its slot.

DW Decking is my pick for HDB balcony and value-focused jobs, and it is the one I would look at if you want the reviews to back the booking. It carries a 4.9-star rating across its Google reviews, which is a healthy signal in a trade where finish quality varies a lot, and its whole positioning is affordable, straightforward decking done well rather than showroom theatre.

The scope is broad and practical: composite and WPC decking, natural timber including Chengal, plus balcony decking and the varnishing, repair and replacement work that keeps an existing deck alive. That maintenance side is genuinely useful, because a timber deck needs re-oiling and the occasional board swap, and having the contractor who can install it also service it later is convenient. Note there is no walk-in showroom, so this is a survey-and-quote outfit. For a well-reviewed, wallet-friendly balcony or timber deck, DW Decking is a fair, safe pick.

Good Wood is the other premium WPC specialist I rate, and it is a solid alternative to shortlist next to Tulou and Evorich when composite is your material. It positions itself squarely as a wood plastic composite decking specialist, with a team drawn from the wood industry, and it carries several composite lines including Duradeck and its Rustic and Hidecki collections, so there is a real range of tones and textures to compare rather than a single house board.

Beyond composite it also handles timber decking and fencing, plus stairs, handrails and cladding, which makes it handy if your outdoor project is more than just the floor of the deck. The pitch is the usual composite upside, minimal upkeep and a boost to your property value, done by people who work with wood daily. For a good-value premium WPC deck with a decent choice of finishes, Good Wood deserves a place on your comparison list.

Floorrich is the name to know if you want your decking handled by the same specialist doing your indoor floors. It has been a one-stop flooring and decking provider since 2009, covering vinyl, engineered wood and solid timber indoors alongside composite decking outdoors, so it can coordinate a matching look from the living room out to the balcony under one roof.

Its FirmaDeck composite decking is the outdoor line, an engineered wood-plastic composite built for our weather with the usual low-maintenance, termite-proof and splinter-free benefits. What I like is the breadth plus the emphasis on non-toxic, low-emission products and in-house installation teams, with reviews consistently praising the value against the quality. If you are already renovating and would rather not juggle a separate decking contractor, Floorrich is a sensible, convenient single point of contact for the whole surface package.

Hue Landscape rounds out the list as the pick when the deck is part of a wider garden, poolside or landscaping job rather than a standalone balcony. It offers both composite and natural timber decking, and because it is a landscaping outfit at heart, it thinks about the deck in relation to the planting, the paving and the drainage around it, which is exactly the perspective you want for a ground-level terrace or a pool surround.

For a landed home garden, a poolside terrace, or any project where the decking needs to sit into a designed outdoor space rather than just cover a floor, that landscape-first approach pays off, because the slope, run-off and edge details get considered up front instead of being patched later. If your deck is one element of a bigger outdoor makeover, Hue Landscape is the natural fit to have quote alongside the pure decking specialists.

Prices move with the board grade, the brand, the substructure (aluminium frames and adjustable pedestals cost more than basic timber joists), how much levelling and waterproofing prep the area needs, and how the deck is finished at the edges. Location changes it too. A small HDB or condo balcony often works out higher per square foot than a large open patio, because the fixed costs of the survey, the frame and the waterproofing check are spread over fewer boards. A poolside or wet-area deck usually costs a little more again, because it needs an anti-slip surface and a more robust, well-drained substructure to cope with constant splashing. Always measure your area early and compare quotes on the same material, board grade and substructure, because that is the only fair comparison.

1. The right material advice, not just a hard sell. A good contractor asks where the deck goes, whether it is a covered balcony or a fully exposed poolside, and how much upkeep you are willing to do, then recommends composite, hardwood or Accoya accordingly rather than pushing the one line it stocks.
2. A proper substructure and drainage plan. The joists, the adjustable pedestals and the drainage gaps under the boards are what keep the deck sound in our rain. Springy boards, ponding water or a frame that traps moisture are the classic signs this was skipped, so make the frame part of the quote.
3. Waterproofing respected, not damaged. On a balcony or terrace the deck sits over a waterproofing membrane and drainage outlets, and a good contractor lays over them without piercing or blocking them. If yours is failing, sort it first with a waterproofing specialist, because a deck over a leaking balcony just hides the problem.
4. Honesty about HDB rules. On an HDB balcony you generally lay decking over the existing floor rather than hacking it, and you must not damage or obstruct the balcony drainage and waterproofing, with some works needing approval. Check the current guidelines on HDB before you commit, and for structural or safety standards on raised or rooftop decks you can also reference BCA.
5. Slip resistance and a real warranty in writing. Ask for an anti-slip textured or grooved surface for any wet or poolside area, and get the warranty covering the board, the substructure and the workmanship in writing, because installation and frame faults are where decks actually fail.

I am not a decking company and nobody paid to be on this list. I built it the way I research any outdoor renovation category: reading through Google reviews, renovation and landscaping forums and local guides, checking each contractor's live website for what it actually supplies and installs, and weighing the difference between a composite-first shop and a genuine hardwood specialist.

Prices, ranges and ratings shift over time, so treat the figures here as a guide rather than a quote, and confirm the current numbers, warranty terms and substructure details with the contractor before you commit. My aim was simple: give you a shortlist I would genuinely use myself, led by a strong composite specialist and covering both the low-maintenance and the real-timber routes.

Neither is universally better, they solve different priorities, so the honest answer is that it depends on how much upkeep you want to do. Composite and WPC win on maintenance: they are termite proof, splinter free, do not need yearly oiling and shrug off our rain and humidity, which is why they are the default for most balconies and busy family homes. The trade-offs are that a dark composite board can get warm underfoot in direct afternoon sun, and even a good board never quite matches the depth of real grain. Natural timber like Chengal, Balau or Merbau gives you that unbeatable warmth and ages beautifully, but it greys and needs periodic sanding and re-oiling to hold its colour, so you are buying a look in exchange for ongoing care. Accoya sits in between, a modified wood that behaves with the stability of composite while still being genuine timber. For a low-fuss balcony, I lean composite; for a statement garden or poolside deck where you love the material, real hardwood or Accoya is worth the maintenance.

In most cases yes, but with rules. On an HDB balcony you generally lay the decking over the existing floor finish rather than hacking out the original screed, which keeps cost and mess down and protects the waterproofing below. The critical constraints are that you must not damage or obstruct the balcony drainage outlets and the waterproofing membrane, and you should keep the deck removable enough that the drainage can still be inspected and maintained. Some balcony works need HDB approval, so always check the current renovation guidelines on the HDB website or ask your contractor to confirm before any decking goes down. A good decking contractor will raise the boards on a drained substructure that lets water run to the existing outlets rather than sealing the balcony floor and trapping it.

On any raised balcony, terrace or rooftop over a living space, yes, and it is the single most important thing under the boards. The deck itself is not the waterproof layer, the membrane on the concrete below it is, and the decking simply sits over that on a drained frame. If the existing waterproofing is failing, laying a deck on top only hides the leak while it keeps travelling into the unit below, so the membrane has to be sound first. That is why I treat decking and waterproofing as a pair on any balcony job. If yours is old or you see water marks on the ceiling below, get a waterproofing specialist to check and, if needed, redo the membrane before the deck goes on. A ground-level garden deck on soil is more forgiving, but it still needs good drainage and airflow underneath so the frame does not sit in standing water.

It depends on the material and the care. A quality capped composite or WPC deck typically lasts well over a decade with almost no maintenance beyond an occasional rinse, and premium brands back that with long warranties, which is a big part of their appeal in our sun and rain. Natural hardwoods like Chengal, Balau and Merbau can last a very long time too, Chengal especially given its natural durability, but only if you maintain them, sanding and re-oiling periodically to fight the greying and surface weathering that constant sun and humidity cause. Accoya is engineered for exactly this climate and is highly rot resistant, so it holds up well with modest care. Across every material, the substructure and drainage are the hidden factor: a deck on a well-drained, non-rotting frame lasts far longer than identical boards laid over trapped water, so the frame quality matters as much as the boards on top.
