Washroom sealing for commercial buildings in Kennington
Not every silicone belongs in a washroom. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you are dealing with failed sealant in a tea point or staff kitchen and failed sealant behind washroom basins, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kennington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Jobs in a smaller place such as Kennington are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

FAQs: Kennington
Would you work within a site like Warneford Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Is Kennington off your patch?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes a few hours for one toilet block, with bigger buildings phased across a number of visits. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.
Aftercare for building managers
For the best life from the joints:
- Squeegee showers and trays after busy periods
- Note failing joints building by building
- Inspect washroom sealant regularly
- Report split joints at trays and basins early
We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used, and it helps if signs stay up until then.
Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Swollen or delaminated boards behind panels or vanity tops
- A dripping waste or valve behind a panel
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Kitchens and tea points
- Urinals and WCs
- IPS panels and cubicles
- Vanity units and basins
Signs you need washroom sealing in Kennington
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Clients normally get in touch after noticing one or more of the following:
- Sealant lifting along a tray edge
- Stained sealant around pans and urinals
- Users noticing mouldy joints
- Open joints at the base of cubicle panels
For an occupier at a site such as Sandford Lane Industrial Estate, which lies south-east of Kennington, the canteen and welfare facilities need cleanable joints as much as any office.
What to look for in a quote

Related advice
Leave it or put it right?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Small buildings around Kennington suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
