About our washroom sealing in Cold Harbour
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. Gaps in those places let water get under the floor or behind panels so they get particular attention. If you’re dealing with users noticing mouldy joints and mould spotting along silicone joints, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Cold Harbour is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Cold Harbour, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould usually can’t be cleaned, so it is cut out and replaced.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to call us in Cold Harbour
Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.
Most enquiries start with one or more of the following:
- Mould spotting along silicone joints
- Complaints from staff, guests or users about tired washrooms
- Failed sealant in a tea point or staff kitchen
- Resealing that didn’t last because the old bead stayed
Where you are responsible for a hall attached to a building such as Church of St Lawrence, its kitchen and toilets need sealant that stays cleanable.
Questions to ask before you book
- How they handle RAMS and site documents
- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it
- Will failed sealant be removed rather than covered?
Why act early in Cold Harbour
Leaving the job until a shutdown often means living with it for months. With phasing, the work can go ahead while most facilities stay open. Older rural buildings around Cold Harbour move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Questions about Cold Harbour
Could you schedule work at a campus like Canterbury Christ Church University for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Must every washroom in our Cold Harbour building shut while you work?
Usually only some of them, for a short time. We work in phases so other facilities stay open. We will tell you the curing time for the product before we start.
Do you use special sealant for toilets and showers?
An anti-mould sanitary silicone in most cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. We plan the phasing around that so there are always rooms open.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
Keeping the joints sound
To get the most from the new sealant:
- Include joints in routine washroom inspections
- Make sure washroom ventilation is running
- Keep a record of which washrooms need attention
- Keep washrooms out of use until we say the sealant has cured
Keep extract fans working and vents clear. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
Boards behind panels and vanity tops can swell when water gets past a failed joint. Once that happens, a reseal won’t fix them.
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water escaping beneath the floor rather than through a joint
- Fittings that move too much to hold a bead
- Condensation from failed extract fans
If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Site staff or a sealant specialist?
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
