About our washroom sealing in Hatherden
When mould has spotted a silicone joint, more cleaning won’t remove it. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. If you are dealing with panel joints letting water behind and mould spotting along silicone joints, we can help, on kitchens and tea points, accessible toilets and changing rooms and IPS panels and cubicles alike. Facilities teams, main contractors and managing agents in Hatherden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Rural businesses near smaller places such as Hatherden, from cafés to event venues, rely on washrooms and kitchens that stay clean. We plan the work around bookings and opening times.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Your questions answered
Must every washroom in our Hatherden building shut while you work?
Not all at once. We take one block of facilities at a time. We’ll tell you the curing time for the product before we start.
Is Hatherden too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What sealant do you use in washrooms?
An anti-mould sanitary silicone for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly.

What happens if it’s left?
A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. Around Hatherden, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Commercial washrooms in Hatherden
Hatherden lies roughly 63 miles out from central London. Washrooms in commuter-belt offices take constant weekday traffic, so we work a block of facilities at a time.
Where you are responsible for a hall attached to a building such as Christchurch, its kitchen and toilets need sealant that stays cleanable. For an occupier at a site such as Portway Industrial Estate, 2.6 miles south of Hatherden, the canteen and welfare facilities need cleanable joints as much as any office.

What we are called out for in Hatherden
Commercial cleaning is harder on sealant than everyday use. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
If one of these sounds familiar, it’s time for a closer look:
- Stained sealant around pans and urinals
- Sealant laid over old silicone and now peeling
- Washrooms that look worn because of the sealant
- Panel joints letting water behind
Pupil toilets at schools like Hatherden Church of England Primary School take heavy daily use, and the holidays give the window to reseal.

What sets the cost
We price every job individually. The main factors are:
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- The total length or number of joints
- Whether the work must be split into stages
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
Sending details for a quote
However big the job, these details speed things up:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- Your programme or deadline
- Any specification or named product
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
How the job changes by surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.
Urinals and WC pans
The joint between a pan and the floor is easy to overlook. We include them in the survey.
