About our washroom sealing in Holtsmere End
In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning and mould that roots into it can’t be cleaned away. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. We work on showers, trays and wet room floors, IPS panels and cubicles and kitchens and tea points, and what we are called in for most is black mould inside silicone joints that cleaning can’t shift and sealant laid over old silicone and now peeling. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Holtsmere End, that means joint design, primers and backing rod as standard.
Smaller places such as Holtsmere End still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Your questions answered
Is hospital work, at somewhere like Hemel Hempstead Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will you plan work around the academic year at somewhere like West Herts College?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How many days will you need on site?
That varies with the scale of the job, though a typical visit typically takes half a day to a day per washroom, depending on the number of fittings. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you phase washroom resealing?
We phase it so users always have somewhere to go. We work through the building a room or section at a time. Tell us your site hours and access windows and we’ll plan around them.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work in hospitals, clinics and care homes?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a morning or so for a small washroom, longer where showers and changing rooms are included.

Advice
Keeping the joints sound
Once the work is signed off, these steps help:
- Leave signs up until the cure time is over
- Share your site rules when you send details
- Clean sealant with gentle products and a soft cloth
- Include joints in routine washroom inspections
Ventilation is half the battle. A room that stays damp will grow mould on almost anything, so get faulty extract looked at.
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 failed joints are worth acting on quickly.
Surface by surface
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant and we look at them as one job.
Why it’s worth doing now in Holtsmere End
Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. Sound, smooth joints are much easier to keep clean. For buildings around smaller places like Holtsmere End, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Hollow tiles or loose panels behind the joint
- Failed tanking beneath a wet-room floor or behind tiles
- A room that stays damp because ventilation isn’t working
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we will tell you honestly.
