About our washroom sealing in Three Ashes
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. Only replacement gets rid of it for good. Site teams most often ask us about kitchen worktop joints that can’t be kept clean and black mould inside silicone joints that cleaning can’t shift, on accessible toilets and changing rooms, urinals and WCs and kitchens and tea points. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Three Ashes, that means joint design, primers and backing rod as standard.
In and around smaller places like Three Ashes, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Different surfaces, different methods
IPS and cubicle panels
Swollen or delaminated boards need replacing and we’ll point out any we see.
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors so the edges are checked carefully.
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Three Ashes can be grouped with others nearby. A fixed quote is given before anything starts.

Building owners, agents and FMs in Three Ashes
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Leave it or put it right?
Water gets behind panels and under floors through a failed joint. That can lead to swollen boards, marked ceilings below and lingering smells which costs more to fix than a reseal. Converted and older buildings near places like Three Ashes tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Clear standing water from shower floors where possible
- Report split joints at trays and basins early
- Mention any site permits or estates rules at quote stage
- Note failing joints building by building
Ask your cleaning team to use gentle products and soft cloths on sealant. Strong acids, solvents and scourers wear the surface and give mould a start.
Mouldy sealant only gets harder to ignore, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

Three Ashes: questions and answers
Will the toilets in our Three Ashes building be out of use?
Normally only some of them, for a short time. We work in phases so other facilities stay open. Each area is handed back once the sealant has cured enough to use.
Is Three Ashes too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Doing it in-house
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
