Honest fit check

Where WPC earns its keep — and where it doesn't.

It's the right call when…

  • You want a timber-look composite board and can follow its care instructions
  • You want to compare the complete installed scope, including boards, frame and finishing
  • You are planning a balcony, patio or garden deck with the board selected for its sun and rain exposure
  • You want to choose the grain and colour from a physical sample and understand its care requirements

Check the specification when…

  • The proposed boards have not been confirmed as suitable for the exposure of your space
  • You expect a finish with no fading or surface wear without checking its maintenance and warranty terms
  • The space will have heavy foot traffic: confirm the proposed board and supporting frame suit that use
What it looks like finished

Timber-look boards for your outdoor space.

Wood-plastic composite combines wood fibre and polymer, with finishes that can resemble timber. Compare the selected board's grain, surface and care instructions with a physical sample.

Board and sample
Ask for the board manufacturer or model, profile, dimensions, grain and colour sample. WPC describes a material family rather than one identical product.
Use and exposure
Describe the direct sun, rain and intended use. Confirm that the quoted boards and their warranty terms suit those conditions.
Installation
Check the specified supporting frame, board spacing, fixings, edge trim, door thresholds and access to drains.
Care and cover
Obtain cleaning instructions and written warranty coverage for the boards, finish and installation. Compare these alongside the installed price.

WPC decking for a condo balcony

Exterior Design supplies and installs WPC composite decking for condominium balconies, patios and gardens in Singapore. For a balcony, compare a physical board sample alongside the proposed frame, finished floor height and access to drains. We can discuss the deck on its own or with zip blinds if you also want side screening.

Send photos for a quote

Send the approximate balcony dimensions and photos of the floor, doors, edges and drains. Include a wider photo showing sun and rain exposure, and say whether there is existing decking. The board, supporting work and job-specific terms are confirmed in the written quotation.

Questions

The questions we actually get.

Short answers, and a plain no when the honest answer is that a figure is not confirmed yet.

Who supplies and installs WPC composite decking in Singapore?
Yes. Exterior Design supplies and installs wood-plastic composite decking for balconies, patios and gardens in Singapore. We check the space and supporting structure before confirming the board system in your quotation.
Can WPC decking be installed over an existing balcony floor?
That depends on the existing floor, drainage, support and available finished height. Send photos of the whole balcony, floor and edges so we can assess the layout before recommending a deck build-up.
What affects a WPC decking quotation?
The deck area and shape, supporting substructure, site access and edge details affect the scope. Send the property type, rough dimensions and photos of the space. We confirm the material and job-specific terms in writing.
Does WPC decking need sealing or staining?
Care requirements depend on the selected composite board. Ask for the manufacturer’s cleaning and maintenance instructions, and check whether any treatment is permitted or required under its warranty.
Can composite decking follow a curve?
A curved deck layout needs the board direction, edge cuts, trim and supporting frame planned together. Send the shape and dimensions for assessment. Do not assume that the boards themselves can be bent; the proposed layout must suit the selected board system.
How do I tell WPC and aluminium apart in a photograph?
Often you cannot, because aluminium decking is commonly sold with a wood-grain finish. Do not choose from a gallery. The board material on your job is named in your written quotation.
Can you install WPC decking as part of a roofing and blinds project?
Yes. WPC decking is part of the range Exterior Design supplies and installs. We can assess the decking, roofing and zip blinds together and confirm the board system and installation details for the intended space.
Do I need to choose WPC or aluminium before contacting you?
No. Tell us how you use the space, its exposure to sun and rain and the look you prefer. We can compare the available decking options and confirm the actual material and job-specific terms in your quotation.
What is WPC composite decking made of?
WPC means wood-plastic composite: a decking board made from wood fibre and polymer. It is a different material from natural timber or aluminium, even when the finishes look similar. Exterior Design confirms the supplied board model, grain and colour in the quotation.
How is WPC decking different from natural timber decking?
WPC is a wood-plastic composite board rather than a natural timber plank. Compare a physical sample, board specification and cleaning and treatment instructions for the selected product, including the conditions of its written warranty.
Can I compare WPC and aluminium decking samples in Singapore?
Yes. Exterior Design keeps decking samples at 6 Ubi Road 1, #04-05 Wintech Centre, Singapore 408726. Contact us to discuss your space and compare the available board materials and finishes before deciding.
Does new WPC decking remove the need to check balcony drainage?
No. The existing floor, drain access, finished deck height and door thresholds still need to be assessed. Exterior Design considers these together with the board layout and supporting frame; changing the visible boards alone does not resolve an underlying drainage problem.
Who installs condo balcony decking in Singapore?
Exterior Design supplies and installs WPC and aluminium decking for condominium balconies in Singapore. We assess the existing floor, drainage, supporting structure and available finished height before confirming the actual board system. The material is named in your quotation; a timber-look photograph alone does not establish whether the boards are WPC or aluminium.
How much does balcony decking cost in Singapore?
The quotation depends on the balcony area and shape, actual board system, supporting frame, edge finishing and site access. Existing floor conditions and any work needed around thresholds or drains also affect the scope. Send dimensions and photos, then compare quotations for the same board, frame, installation work and written warranty. Ask whether any existing-deck removal or other additional work is required and how it would be priced.

One photo is all it takes.

Send photos and rough dimensions if available. We will review the space and discuss the installation scope before confirming your quotation.
