Keeping Prestonville washrooms open while we work
Prestonville lies within about 1 mile of the sea, and seaside hospitality typically has a peak season that works washrooms hard. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. The 2 miles around Prestonville include five care or nursing homes. In a care setting, a mouldy or lifting joint in a wet room is a hygiene issue as much as a cosmetic one. Rooms are done a few at a time at times agreed with the home.
At a college such as Waterbear College Brighton, 0.9 miles south-east of Prestonville, washroom and kitchen sealant is best renewed in the holidays or in phases during term. Clinical washrooms at sites like The Montefiore Hospital (to the south-west of Prestonville) are scheduled with the ward so the room is out of use for as little time as possible. For a campus such as University of Brighton Moulesecoomb Campus, 1.5 miles to the east of Prestonville, showers in residences and washrooms in teaching blocks can be programmed around term dates.
Prestonville is about 1 mile west of Brighton, in Brighton and Hove. Any commercial site in Prestonville is covered, whether it’s a single job or part of a planned programme. Prestonville is one of 29 places in Brighton and Hove on our list for washrooms and wet areas.

How we handle washroom sealing in Prestonville
Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you’re dealing with failed sealant behind washroom basins and users noticing mouldy joints, we can put it right, whatever the surface. Searching for sealant specialists in Prestonville? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Pub and restaurant kitchens around smaller places like Prestonville work hard on their joints. Sealed joints at sinks, worktops and splashbacks help keep the kitchen cleanable.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Surface by surface
Kitchens and tea points
Kitchen joints need to be smooth and sealed so they can be cleaned properly. Food-safe sealants are used where food may touch the joint.
Basins and vanity tops
Natural stone tops can be marked by acetoxy silicone, so the product is chosen to suit.

On site: what to expect

- Every washroom is checked joint by joint, with loose panels, leaks or damp noted for the right trade.
- A phasing plan keeps part of the building’s facilities in use at all times.
- 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.
- Each room is handed back once the sealant has had its cure time.

When something else is needed
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Swollen or delaminated boards behind panels or vanity tops
- Leaks through tanking or membranes below the finishes
- Hollow tiles or loose panels behind the joint
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

- Note failing joints building by building
- Act on the first split you see at a shower tray
- Keep washrooms out of use until we say the sealant has cured

Questions about Prestonville
Will our hotel in Prestonville need to close for the work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Can work in a care setting near Prestonville go ahead while residents are there?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.
What guarantee comes with washroom resealing?
There is a 12-month guarantee on our workmanship, and we carry public liability insurance.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is it OK to put new silicone on top of the old?
The whole of the old bead is removed and the surfaces cleaned first. That’s what makes the new joint last.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
