Frequently Asked Questions (FAQ)
What is waterproofing and why is it important for Singapore homes?
Waterproofing involves applying protective systems to prevent water intrusion into areas like bathrooms, roofs, balconies, and walls, and is especially crucial in Singapore’s climate of heavy rainfall and high humidity, where inadequate protection can lead to leaks, dampness, mould growth, and eventually serious issues such as concrete spalling and structural damage.
How does Singapore's climate and monsoon season affect my property's waterproofing?
Singapore’s tropical climate continuously stresses waterproofing systems, accelerating deterioration, while monsoon conditions with prolonged rainfall, increased ponding on roofs and balconies, and the expansion of hairline cracks further weaken protection and increase the risk of water seepage over time, especially without proper maintenance.
What are the most common signs that my property needs waterproofing in Singapore?
Early warning signs such as water stains, peeling paint, damp patches, mould growth, musty odours, dripping water, or hollow tiles indicate potential waterproofing failure and should be inspected promptly and rectified before the issue worsens.
How long does waterproofing last in Singapore's humid weather?
Waterproofing typically lasts 5–10 years for bathrooms, 5–8 years for roofs and balconies, and 5–7 years for external walls, but its actual lifespan depends on various factors such as material quality, workmanship, weather exposure, and usage conditions.
What is the difference between waterproofing and water resistance?
Waterproofing completely blocks water penetration (commonly used for roofs, toilets, and basements), whereas water resistance only slows moisture ingress, making proper waterproofing essential for wet areas in Singapore homes where water resistance alone is insufficient.
What types of waterproofing services does WaterproofingSG offer?
We offer a comprehensive range of waterproofing solutions, including toilet and bathroom waterproofing, roof and balcony protection, external wall treatments, ceiling leak repairs, basement waterproofing, PU/epoxy crack injection, and non-hacking waterproofing solutions.
Do you provide waterproofing services for both HDB flats, condominiums and private property?
Yes, we provide waterproofing works for HDB flats (BTO and resale), private condominiums, and landed properties, with strong familiarity in HDB regulations and condo MCST requirements.
Do you provide waterproofing services for commercial buildings, is this costly?
Yes, we provide waterproofing services for commercial properties including offices, retail shops, warehouses, and MCST-managed developments, with costs depending on many factors such as area size, leakage severity, and site accessibility, while larger projects are generally more cost-efficient on a per square foot basis
Can you do all waterproofing without hacking tiles?
Yes, non-hacking waterproofing solutions such as clear penetrative treatment, surface-applied coatings over tiles, and injection grouting can often be used, but if the underlying waterproofing membrane has fully failed, hacking and replacement may still be required.
What is involved in roof waterproofing in Singapore?
Roof waterproofing typically involves surface cleaning and preparation, crack repairs, construction of angle fillets wherever necessary, application of a liquid or sheet-based waterproof membrane, and a protective coating, with flat roofs requiring extra attention due to their higher risk of water ponding.
Can waterproofing be done over existing tiles or surfaces?
Yes, waterproofing can often be applied over existing finishes using methods such as transparent coatings, liquid-applied membranes, or injection grouting, but suitability depends on the substrate condition, severity of leakage, and whether the original membrane has fully failed, making a proper assessment essential.
Why does my toilet leak only when showering?
If leakage occurs only during shower use, it typically indicates wet area waterproofing failure caused by deteriorated membranes, gaps in grout or silicone joints, or poor slope leading to water ponding.
Will repainting or re-grouting solve my water leakage problem?
No, repainting or re-grouting only addresses surface symptoms and not the root cause, as repainting merely conceals stains and re-grouting improves appearance without stopping water penetration, so if the underlying waterproofing has failed, the leakage will return unless the source is properly repaired.
How do you fix ceiling water leakage in Singapore?
Ceiling leaks are typically caused by failed upstairs bathroom waterproofing, pipe leaks, or external wall seepage, and should be addressed through proper leak detection, repairing the source of the leakage (not just patching the ceiling), and reinstating the affected ceiling areas.
Why all my waterproofing services engage is not able to solve my water leakage?
Recurring leaks are often caused by incorrect diagnosis, poor workmanship, unsuitable materials, or multiple unresolved sources, making proper leak detection essential before carrying out any repair work.
What is basement waterproofing and when do I need it?
Basement waterproofing prevents groundwater from entering underground structures and is necessary when signs such as wall seepage, dampness or mould, or hydrostatic pressure build-ups behind walls are present.
Do you offer leak detection services, and how does it work?
Yes, we use non-destructive leak detection methods such as thermal imaging, moisture meters, and ultrasonic detection to accurately identify the source of leaks without unnecessary hacking.
How long does a waterproofing job typically take to complete?
Waterproofing works typically take 1–2 days for minor repairs, 2–5 days for bathrooms, and 3–7 days for roofs, although drying and curing times may extend the overall duration.
Do I need to vacate my home during waterproofing works?
Not usually, but you may need to temporarily avoid using affected areas such as bathrooms or restrict access during works, while major projects may require short-term relocation for safety and convenience.
What should I do to check if this is a waterproofing issue?
You can perform quick checks by observing if leaks worsen during rain (likely external issues), occur when the upstairs unit uses water (likely bathroom-related waterproofing issues), or persist as constant dripping (possible pipe leak), though a professional inspection is recommended for accurate diagnosis.
What warranty do you provide for your waterproofing works?
Most of our waterproofing works come with a 1 to 5-year warranty depending on the system, scope, and site conditions, with localized spot repairs typically covered for 1 year, while new roof waterproofing and full system replacements generally carry a 3–5 year warranty.
Who is responsible for water leakage between HDB floors?
In Singapore HDB flats, the upper unit owner is typically responsible for toilet-related leaks, while responsibility for pipe leaks depends on whether the pipes are classified as common or private, with HDB often conducting joint inspections to determine liability.
Can HDB or condo management be involved in waterproofing disputes with neighbours?
Yes, they can. HDB can assist with mediation and inspections, while condo MCSTs can arrange joint inspections and enforce necessary repairs, making proper reporting important for faster dispute resolution.
What should I do immediately when I discover a water leak in my Singapore home?
Take immediate action by turning off the water supply if necessary, containing the leak to minimise damage, informing your neighbour or management, and engaging a professional for inspection, as delays can lead to more severe issues.
Is there a report before and after waterproofing if engage a waterproofing?
Yes, professional contractors can provide documentation such as pre-work inspection reports, leak detection findings, method statements, and post-work completion reports.
Can waterproofing be done during rainy season in Singapore?
Yes, but certain works may be delayed or require weather protection.
Why does my wall feel damp even when there is no visible leak?
Damp walls without visible dripping are typically caused by slow moisture ingress such as external wall seepage during rain, failed waterproofing behind tiles, capillary action, or poor ventilation, and should be addressed early to prevent progression into peeling paint, mould growth, and internal damage.
