Advice
How we handle washroom sealing in Kentsboro
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself, which is why it comes back however often it is treated. Replacing the bead is the lasting treatment. If you’re dealing with mould spotting along silicone joints and shower tray joints that have opened up, we can put it right. Most enquiries from Kentsboro start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Smaller places such as Kentsboro still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Common problems we fix in Kentsboro
We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting, and they stain, crack or wash out.
Common reasons buildings call us in:
- Sealant stained black around basins and showers
- Shower tray joints that have opened up
- Failed joints along IPS and cubicle panels
- Failed sealant in a tea point or staff kitchen
In any commercial washroom in or near Kentsboro, mouldy sealant is cut out rather than cleaned, and anti-mould sanitary silicone goes on clean, dry joints.

Looking after the joints
After handover, these steps help:
- Note failing joints building by building
- Avoid scourers and harsh descalers on silicone
- Add sealant joints to planned maintenance checks
- Keep washrooms out of use until we say the sealant has cured
Mild cleaning products and non-abrasive cloths look after sanitary silicone best. Strong acids, solvents and scourers wear the surface and give mould a start.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Common questions from Kentsboro clients
Do we have to close all our washrooms in Kentsboro for resealing?
Not all at once. We take one block of facilities at a time. Each area is handed back once the sealant has cured enough to use.
Can you take on a job at a hospital such as Andover War Memorial Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is Kentsboro in your area?
Yes. Sites across Kentsboro are covered.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
