What the job involves on each surface
Urinals and WC pans
Pan and urinal joints face constant cleaning and splashing. Once they discolour or split, they hold odours and make the room look neglected.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.

FAQs: Northney
Must a hotel around Northney close while you work?
In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Do you take on work at healthcare sites like Elmleigh Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Do you have public liability insurance?
Yes. We’re fully insured, including public liability cover.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email us. Include photos or drawings if you have them.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When can showers be used after new sealant?
Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.
What happens if old sealant might contain asbestos?
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. Removing asbestos is a job for asbestos specialists, not us.

What else we do in Northney
Do you need washroom sealing in Northney?
Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.
These are often picked up first by site or facilities staff:
- Washrooms that look worn because of the sealant
- Sealant lifting along a tray edge
- A new bead over an old one coming away
- Stained or open joints at kitchen sinks and worktops
Welfare facilities in units on estates such as Finchwood Farm Industrial Estate, 1 mile south of Northney, have showers, toilets and kitchens with sealant that works hard.
What your quote should include
- Will RAMS and insurance details be available?
- The named product and why it was chosen
- Whether old or failed sealant will be cut out, not overlaid
- Do they follow the manufacturer’s priming guidance?
Diagnose, treat, sign off
On arrival, 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 usually takes a morning or so for a small washroom, longer where showers and changing rooms are included. Smaller jobs around Northney can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- First, the phasing is agreed so facilities stay open.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Before we start on site

Related advice
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, 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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Sanitary sealant for Northney buildings
Northney sits close to the coast, within about 1 mile, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, which is why off-season resealing makes sense. Northney has a number of hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. Rooms are done in turn so most stay available.
Hotels such as Ropemaker Hotel (1.4 miles north of Northney) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Halls of residence and teaching buildings at universities such as University of Portsmouth - Langstone Campus, 4.1 miles south-west of Northney, are easiest to reseal during vacations.

Honest limits

- Hollow tiles or loose panels behind the joint
- Panel boards already damaged by water
- Condensation from failed extract fans
