How we handle washroom sealing in Southwater
Washroom joints need the right sealant, not whatever is to hand. 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. We work on accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles, and the failures we’re asked to look at most are black mould inside silicone joints that cleaning can’t shift and a new bead over an old one coming away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Southwater, that means joint design, primers and backing rod as standard.
A place of Southwater’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Why it’s worth doing now in Southwater
Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and cleaners stop fighting a losing battle. Small buildings around Southwater suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What else we do in Southwater
FAQs: Southwater
Is Southwater off your patch?
No. Places such as Southwater are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Do we have to close all our washrooms in Southwater for resealing?
Not all at once. We take one block of facilities at a time. We will tell you the curing time for the product before we start.
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.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you work in hospitals, clinics and care homes?
Yes, healthcare and care settings are part of our work. Any records you need are confirmed with the quote before we start.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Note failing joints building by building
- Tell us about infection-control or permit rules before we quote
- Act on the first split you see at a shower tray
- Clear standing water from shower floors where possible
Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
Our process
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a job in Southwater, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Getting the site ready
- Let us know about inductions and permits
- Let building users know which areas are affected
- Point out any areas we must not close

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Sanitary sealant for Southwater buildings
Central London is about 34 miles from Southwater, within the office belt around the capital. Washrooms in commuter-belt offices take constant weekday traffic, so we phase work to keep some facilities open.
If you manage an office at a site such as Southwater Business Park, under half a mile to the south-west of Southwater, the washrooms and tea points can be done a floor at a time. Pupil toilets at schools like Southwater Infant Academy take heavy daily use, and the holidays give the window to reseal. Church halls and community buildings, such as those at Holy Innocents Church, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

When it isn’t the sealant
