Decon Builders Pte Ltd is a builder based at 208 Hougang St 21 in Hougang, Singapore, registered with the Building and Construction Authority and holding a 5.0 Google rating. Choosing a builder here starts with paperwork: BCA licence grades cap the size and value of works a firm can legally take on, so check the licence before signing anything. If a job involves an HDB flat, a good builder will know which renovations need HDB approval and will secure the permits before any demolition starts, because unapproved works can end in reinstatement orders. Regulars also swear by an itemised quote covering materials, labour and debris disposal, with working hours agreed up front, since estate renovation times are restricted and close neighbours notice everything. For homeowners around Hougang's blocks and landed streets, this highly rated local firm is a convenient place to start.
