Frequently Asked Questions
How do I choose a reliable waterproofing contractor in Singapore?
Check for BizSafe certification, verifiable project history, and clear written warranties (Allseal offers up to 10 years on completed works). A reliable waterproofing specialist in Singapore will inspect the site before quoting, explain the root cause of the leak, and recommend the least invasive method that actually solves the problem rather than defaulting to full hacking.
What does a waterproofing company in Singapore typically handle?
A full-service waterproofing company handles bathroom and toilet leaks, balcony and roof waterproofing, concealed pipe leak detection, external wall waterproofing, and planter box or RC roof waterproofing, using methods ranging from non-hacking PU injection and flood infusion through to full membrane replacement for HDB, condo, and commercial properties.
How much do waterproofing services cost in Singapore?
Costs vary by scope: minor bathroom leak repairs typically range S$200-S$1,000, concealed pipe detection and repair S$300-S$1,500+, and full waterproofing with retiling S$3,000-S$5,000+ depending on area and material. A waterproofing specialist should always inspect on-site before giving a firm quote.
Is a waterproofing specialist different from a general contractor?
Yes. A waterproofing specialist focuses specifically on diagnosing leak sources (using thermal imaging, moisture meters, and dye/pressure testing) and applying waterproofing-specific materials and methods, rather than general renovation work. This specialisation matters because incorrect waterproofing work is one of the most common causes of recurring leaks in Singapore homes.
Do waterproofing contractors in Singapore offer warranties?
Reputable waterproofing contractors offer written warranties on completed work, typically ranging from 1 to 10 years depending on the method and area treated. Always get the warranty terms in writing before work begins, and confirm whether it covers materials, labour, or both.
