When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Washroom sealing in Hambrook
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Give us your site hours and access windows and the phasing is planned around them. We work on urinals and WCs, kitchens and tea points and IPS panels and cubicles, and the failures we’re asked to look at most are stained or open joints at kitchen sinks and worktops and users noticing mouldy joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Hambrook, that means joint design, primers and backing rod as standard.
Halls and community buildings near places like Hambrook are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
A 12-month guarantee applies to all our work in West Sussex. Should something we installed fail, ring 01277 525 020 or email the details over and we will come back to it.

Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes half a day to a day per washroom, depending on the number of fittings. For a building around Hambrook, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- A bead of anti-mould sanitary silicone goes in and is tooled to a smooth, cleanable profile.
- Each room is handed back once the sealant has had its cure time.
Getting the site ready
- Flag any permit to work we’ll need
- Confirm the product named in the specification
- Let building users know which areas are affected

Advice
Busy facilities in and around Hambrook
Hambrook lies within about 2 miles of the sea, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. Hambrook has four care or nursing homes no more than 2 miles away. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Rooms are done a few at a time at times agreed with the home.
Clinical washrooms at sites like Havant War Memorial Hospital (to the west of Hambrook) are scheduled with the ward so the room is out of use for as little time as possible. Pupil toilets at schools like Chidham Parochial Primary School take heavy daily use, and the holidays give the window to reseal.

Local landmarks in Hambrook
Recent enquiries here include premises near Bourne Community College and the streets around them. Hambrook’s nearest station is Nutbourne station, about 0.6 miles south of the centre. Other landmarks nearby include Havant War Memorial Hospital (4.7 miles west) and Emsworth Museum (2.5 miles west). Not far away are Nutborne Marshes and Stoke Down.
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Clear standing water from shower floors where possible
- Don’t leave an open joint at a basin or tray
- Report faulty extraction promptly
- Photograph and log failed joints across the estate
Each room goes back into use only when the sealant has cured enough. You will be told when showers and basins can be used again and signage stays in place until that time.
Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Dealing with it while it’s just the sealant keeps it simple.

FAQs: Hambrook
Will you plan work around the academic year at somewhere like University of Chichester?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can work in a care setting near Hambrook go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Any site rules, from signing in to infection control, are agreed before we start.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Will cleaning remove black mould from sealant?
Usually not. The mould is inside the silicone so cleaning only lightens it for a while. Replacement is the lasting fix.
Do you need washroom sealing in Hambrook?
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting, and they stain, crack or wash out.
Common reasons buildings call us in:
- Sealant laid over old silicone and now peeling
- Failed joints along IPS and cubicle panels
- Failed sealant in a tea point or staff kitchen
- Urinal joints that look unhygienic
Where you are responsible for a hall attached to a building such as St Wilfrid's Church and Hall, its kitchen and toilets need sealant that stays cleanable.

Leave it or put it right?
Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. For buildings around smaller places like Hambrook, 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.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
