Introduction
Many Singaporeans assume that black mould in tile grout is just a hygiene issue. It is not. In humid HDB flats and condos, crumbling grout often signals water ingress that has already compromised the waterproofing membrane. The challenge is deciding whether you need a cosmetic fix or a structural repair. This distinction is hard to make without professional input. I researched these providers to help you identify who checks for hidden damage versus who simply patches the surface. This list covers services suitable for wet areas, dry kitchens, and exterior balconies, ensuring you find a contractor who matches the severity of your problem.

1. Mr Grout Singapore
Mr Grout Singapore focuses on the technical aspects of joint failure. Their technicians cut out broken grout, treat mould-affected joints, and repack tile lines in toilets and kitchens. They also replace flexible sealant at basins, toilet bases, shower screens, and internal corners. This dual approach addresses both rigid and flexible joints, which is critical in high-moisture areas.
What’s good
- Inspects the reason for joint failure before quoting
- Protects fixtures and floors during the grinding process
- Handles both grout and sealant, not only the tile joint
What to watch
- Confirm whether work is only on joint level or includes the waterproofing membrane underneath
- Cementitious grout needs time to cure, so plan around shower use
Who it suits
Homeowners who want joint repair and silicone renewal handled in one appointment. If your issue is a major leak, look at Ace Tiling instead.

2. Ace Tiling & Waterproofing Services
Ace Tiling targets wet-area repair work where regrouting alone is insufficient. The team checks for hollow tiles and substrate damage, then quotes for re-waterproofing, patch tiling, or full joint replacement. This is a more invasive service, suitable for bathrooms where grout loss is a symptom of movement or leaks.
What’s good
- Flags hidden issues such as hollow tiles before covering them up
- Can bundle regrouting with toilet waterproofing
- Work sequence follows HDB upgrading and MCST requirements
What to watch
- Job scope can expand once a hollow tile is lifted
- Ask for a separate line item for membrane repair and floor trap replacement
Who it suits
Bathrooms where lost grout is a sign of movement, leaks, or worn waterproofing. If your grout is just dirty, this is overkill.

What’s good
- Willing to take small one-room jobs
- Keeps furniture and cabinet bases covered during work
- Gives plain-language advice on whether to patch or re-tile

4. Khuan Seng Tiling Works
Khuan Seng re-grouts and re-seals condominium bathrooms, balconies, and roof terraces. They use weather-resistant joint material for areas exposed to rain and direct sunlight. This is essential for outdoor spaces where thermal expansion and UV degradation accelerate grout failure.
What’s good
- Understands weather exposure and joint movement on open floors
- Advises on correct expansion joints rather than filling every gap solid
- Suitable for small landed and condo repair scopes
What to watch
- Confirm access to the work area if it is part of MCST common property
- Expansion joints should be cut and filled separately from normal grout lines
Who it suits
Condos and landed homes with open terraces, planter ledges, or balcony tiles that keep leaking after rain. For indoor bathrooms, consider Mr Grout.

5. Solidgrout Services
Solidgrout applies epoxy grout on selected tile floors and walls for clients tired of scrubbing porous cement grout. They also repair existing cementitious joints before applying a sealant top coat. Epoxy is a premium option, offering superior stain resistance and durability in high-traffic or wet areas.
What’s good
- Uses more stain-resistant joint material
- Cleans old mould and weak material before repacking
- Can explain honest differences between epoxy and cement grout
What to watch
- Epoxy grout costs more and needs faster workmanship
- If budget is tight, they may recommend sealing instead of full epoxy replacement
Who it suits

6. Jin Tech Waterproofing
Jin Tech carries out regrouting as a starting step for full waterproofing jobs. The team removes loose joints, inspects the tile base, and applies cement-based waterproofing coatings in toilets, flat roofs, and planter boxes. This is a comprehensive solution for persistent leaks.
What’s good
- Checks where water is coming from before doing cosmetic joint work
- Has membrane coating experience beyond grouting
- Can quote a full reinstatement instead of a quick patch
What to watch
- Regrouting is only a small part of the scope if membrane work is needed
- Ask how many coats of waterproofing are included in the quote
Who it suits
Wet areas where water is escaping through tile joints and damaging false ceilings or the flat below. For minor grout issues, this is unnecessary.

What’s good
- Works across different tile and stone substrates
- Can treat dirt trapped in porous grout before sealing
- Suitable for maintenance after a full re-tiling project
What to watch
- Sealing does not stop grout from cracking if the floor substrate moves
- Re-sealing frequency depends on foot traffic and cleaning chemicals

9. SG Bathroom Grout Services

- Pays attention to corners, edges, and gaps around fixtures
- Can usually finish most bathroom spot jobs within a day
What to watch

How to Choose
| Criterion | Why It Matters | What Good Looks Like |
|---|---|---|
| Grout condition assessment | Surface repairs fail when water sits under old grout or hollow tiles. | Contractor checks for hollow tiles, moisture in walls, and waterproofing damage before quoting. |
| Grout material selection | Cementitious and epoxy grout have different cure times, stain resistance, and cost. | Provider offers a clear choice and explains where epoxy is worth paying for. |
| Scope of sealant and caulking work | Water often enters through flexible sealant at basin, toilet, and shower screen edges. | Quote covers removal and replacement of old silicone in internal corners and around fixtures. |
| Workmanship hygiene | Regrouting creates fine dust and loose debris that can travel through the unit. | Workers use dust barriers, drop sheets, an industrial vacuum, and a clean method of grout disposal. |
| Curing and drying management | New grout can wash out, shrink, or discolour if the area is used too early. | Contractor states the full cure time, protects the joints from water, and does not rush repeated visits. |
| Project scope transparency | A small regrouting job can grow once hollow tiles and damaged membranes are exposed. | Written quote separates joint work, membrane repair, and tile replacement. |
| Guarantee and defects period | Re-grouting should stay solid in normal use and not crack shortly after curing. | Contractor returns to fix shrinkage, hairline cracks, or joint separation without charging a new callout fee. |

FAQ
Can tile regrouting fix water leaking to the flat below?
No, not on its own. Regrouting seals the joints between tiles, but if the waterproofing membrane underneath is damaged, water will still find a path. You need to assess the source of the leak first. If hollow tiles or membrane failure are present, a full waterproofing repair is required. Regrouting alone is a cosmetic fix for minor issues.
Epoxy grout or cementitious grout for a HDB bathroom floor?
Cementitious grout is standard and sufficient for most HDB bathrooms. It is cheaper and easier to repair if damaged. Epoxy grout is more expensive but highly stain-resistant and durable. Choose epoxy if you have dark tiles or high foot traffic where cement grout might stain. For average use, cementitious grout with a sealer is cost-effective.
Do I need to vacate my home for tile regrouting?
You do not need to vacate, but you should clear the immediate work area. Regrouting generates dust and noise, so it is best to keep other rooms closed off. If the work involves extensive hacking or waterproofing, the space may be unusable for a few days. Coordinate with the contractor on timeline and access requirements.
How long after regrouting can I shower or mop?
Cementitious grout typically needs 24 to 48 hours to set, but a full cure can take up to 7 days. Avoid getting the area wet for the first 24 hours. Mopping should wait until the grout is fully cured to prevent washing out the material. Follow the specific instructions provided by your contractor.
What is the difference between grout sealing and regrouting?
Regrouting involves removing old, damaged grout and replacing it with new material. This is a repair job. Grout sealing is a protective treatment applied to new or old grout to repel stains and moisture. Sealing is maintenance, not repair. You can seal old grout to extend its life, but it will not fix cracked or missing grout.
