Washroom sealing for commercial buildings in Portsea
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. If you’re dealing with stained or open joints at kitchen sinks and worktops and washrooms that look worn because of the sealant, we can put it right. A specialist sealant contractor works differently from a general builder: in Portsea, that means joint design, primers and backing rod as standard.
Pub and restaurant kitchens around smaller places like Portsea work hard on their joints. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Why act early in Portsea
Open or mouldy joints are hard to keep hygienic which matters most in healthcare, food and education settings. Sound, smooth joints are much easier to keep clean. In a smaller place such as Portsea, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
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 you will have a fixed figure to work with.

Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- When you need the work done
- The postcode of the building
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It won’t put right:
- Failed tanking beneath a wet-room floor or behind tiles
- Panel boards already damaged by water
- Mould caused by poor ventilation, which will return until the extract is fixed
If you’re not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.
What we seal
- Vanity units and basins
- IPS panels and cubicles
- Urinals and WCs

- Showers, trays and wet room floors
- Kitchens and tea points

Commercial washrooms in Portsea
Portsea is within about 1 mile of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Heavy seasonal use is hard on shower and basin sealant, so resealing in the quieter months keeps rooms ready. The 2 miles around Portsea include eight care or nursing homes. Assisted bathrooms and wet rooms in care settings need sanitary sealant that stays cleanable. We plan the work with the manager so residents are disturbed as little as possible.
At a university such as University of Portsmouth - North Zone, which lies east of Portsea, summer is the usual window for resealing residence bathrooms. Customer toilets and staff facilities at retail sites such as Victory Retail Park, 1 mile to the north-east of Portsea, need sealant that stays clean under heavy use.

FAQs: Portsea
Is Portsea off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Gosport War Memorial Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Is it OK to put new silicone on top of the old?
We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.
Can you reseal washrooms in healthcare buildings?
We do. Your infection-control rules, estates requirements and permits are followed. The work is phased around patients or residents.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Building owners, agents and FMs in Portsea
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
What we’re called out for in Portsea
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges so grime sticks to the damaged surface.
If one of these sounds familiar, it’s time for a closer look:
- Failed sealant in a tea point or staff kitchen
- Users noticing mouldy joints
- A new bead over an old one coming away
- Shower tray joints that have opened up
Toilets at colleges like St Vincent College, 1.3 miles west of Portsea, take heavy use from students and staff alike.
