Washroom sealing for Portsmouth sites

When to call us in Portsmouth
Washrooms are warm, damp and full of organic residue, and silicone joints hold onto all three. Even anti-mould grades can be colonised over time where extraction is poor.
Things that usually lead to an enquiry:
- Open joints along basins and vanity units
- A new bead over an old one coming away
- Mould spotting along silicone joints
- Split or peeling sealant at shower trays
At a university such as University of Portsmouth (1.1 miles south of Portsmouth), summer is the usual window for resealing residence bathrooms.
What your quote should include
- How they’ll work around occupants
- Whether primer will be used where the manufacturer specifies it
- Whether their applicators hold CSCS cards
- The terms of the workmanship guarantee
About our washroom sealing in Portsmouth
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and shower tray joints that have opened up, on showers, trays and wet room floors, IPS panels and cubicles and urinals and WCs. For commercial sealant work in Portsmouth, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a big town such as Portsmouth, public-facing washrooms in shopping centres and leisure buildings stay in use most of the day. Phased work keeps enough facilities open while the sealant is replaced.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the quote is worked out
We price every job individually. The things that drive the figure:
- Phasing around occupants
- Location, for remote and island sites
- The site’s rules and procedures
- Which sealant the job calls for
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
We can often quote from photographs and a few details. It helps to include:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
- The postcode of the building
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Busy facilities in and around Portsmouth
Portsmouth 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. Portsmouth is about 64 miles from central London, in a commuter belt where offices and business parks are common. Office washrooms on business parks see heavy weekday use, which is why the work is phased.
Hotels such as The Avenue Hotel (to the north of Portsmouth) have en suite bathrooms where tired silicone at the bath, tray and basin is replaced room by room. Staff changing rooms and patient toilets at places like St James Hospital, 1.6 miles to the south-east of Portsmouth, need cleanable, sound silicone.

How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For premises in central Portsmouth, deliveries and parking need a bit of planning, while out-of-town estates normally have yards and car parks. Let us know what’s there when you send details.
- We survey each room, count the joints and note anything behind them that needs another trade.
- We agree which rooms close and when, so users always have somewhere to go.
- We strip out the old bead and clean off the residue left behind.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- Rooms reopen after the product’s cure time, and we move to the next.
What we need from you
- Let building users know which areas are affected
- Point out any areas we must not close
- Tell us what induction or permit system the site runs

Advice
Common questions from Portsmouth clients
Can you work around term dates at a campus such as University of Portsmouth?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Will our hotel in Portsmouth need to close for the work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Do you need to remove the old sealant?
We always remove it. Fresh silicone can’t key to an old bead so a bead over the top fails quickly.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes a morning or so for a small washroom, longer where showers and changing rooms are included. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is it possible to just clean mouldy silicone?
Cleaning may lighten it, but the mould returns. We replace the sealant with an anti-mould sanitary grade and point out if ventilation is part of the problem.
Do you cover Portsmouth?
Yes. We cover Portsmouth, and the simplest way to start is to speak to us on 01277 525 020 or email us.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Hollow tiles or loose panels behind the joint
- A room that stays damp because ventilation isn’t working
- Vanity carcasses that have swollen
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we will tell you honestly.
What we seal
- Showers, trays and wet room floors
