Washroom sealing for Test Valley sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
What sealant work can’t fix
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- A dripping waste or valve behind a panel
- Failed tanking beneath a wet-room floor or behind tiles
- Hollow tiles or loose panels behind the joint
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Joints and surfaces we work on
- Urinals and WCs
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Showers, trays and wet room floors
- Vanity units and basins
Washroom sealing for commercial buildings in Test Valley
Whether it’s a single toilet block in Test Valley or a programme across several buildings, we work the same way: details first, then a fixed quote, then the work, then the 12-month guarantee. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote and a site visit is an option. The enquiries we see most involve washrooms that look worn because of the sealant and urinal joints that look unhygienic, on urinals and WCs, showers, trays and wet room floors and vanity units and basins. Whoever orders the work in Test Valley, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Test Valley, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Questions about Test Valley
Is a smaller place like Test Valley outside your area?
No. Places such as Test Valley are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Will the toilets in our Test Valley building be out of use?
Rarely all at once: work is phased so some facilities are always available. We will tell you the curing time for the product before we start.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
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 photos, while larger or less clear jobs get a site visit first.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Test Valley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We inspect each washroom and record the joints to be resealed.

Related advice
Leave it or put it right?
When a washroom looks worn, a refit isn’t the only answer. If the finishes are in good order, replacing the sealant may do much of what’s needed while bigger works are planned. Older rural buildings around Test Valley move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
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 requirements come into it too.

What else we do in Test Valley
Aftercare for building managers
For the best life from the joints:
- Brief cleaning staff to treat joints gently
- Clear standing water from shower floors where possible
- Keep extract fans working and vents clear
- Report split joints at trays and basins early
Add washroom sealant to routine inspections. Look for black spotting, cracks, peeling edges and gaps at the busiest fittings and photograph anything new.
Mouldy sealant only gets harder to ignore and users notice. Dealing with it while it’s just the sealant keeps it simple.
When to call us in Test Valley
Much of the failed sealant we remove was applied over old silicone or residue. New silicone won’t grip the old, so it soon lets go.
If one of these sounds familiar, it’s time for a closer look:
- Complaints from staff, guests or users about tired washrooms
- Split or peeling sealant at shower trays
- Mould spotting along silicone joints
- Stained or open joints at kitchen sinks and worktops
Where you are responsible for a hall attached to a building such as Church of St James, its kitchen and toilets need sealant that stays cleanable.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Proof of insurance
- How the existing material will be dealt with
- Will RAMS and insurance details be available?
