Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water escaping beneath the floor rather than through a joint
- A room that stays damp because ventilation isn’t working
- A dripping waste or valve behind a panel
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.
Joints and surfaces we work on
- Vanity units and basins
- Kitchens and tea points
- Urinals and WCs
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- IPS panels and cubicles
How the job changes by surface
Basins and vanity tops
A failed joint along a vanity unit lets water into the carcass. Resealing early protects the unit.
Healthcare and care settings
Healthcare work is phased so wards, clinics or residents’ areas keep their facilities. Tell us what records you need and we’ll confirm with the quote.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Tell us about infection-control or permit rules before we quote
- Clear standing water from shower floors where possible
- Note failing joints building by building
- Make sure washroom ventilation is running
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
Common problems we fix in Blackness
Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.
If one of these sounds familiar, it’s time for a closer look:
- Resealing that didn’t last because the old bead stayed
- Failed sealant in a tea point or staff kitchen
- Open joints along basins and vanity units
- Discoloured joints around urinals and WC pans
Toilets at places like Hampden Park Retail Park, 1.8 miles to the south of Blackness, are cleaned constantly, so silicone needs to be sound and smooth.

Common questions from Blackness clients
Can you work in a care home near Blackness with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is Blackness off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
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.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, 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.
Washroom sealing around Blackness: what changes locally
With the shore within about 3 miles, Blackness counts as a coastal location, and coastal places often have hotels, guest houses and holiday accommodation with busy seasons. Washrooms used guest after guest wear their sanitary silicone faster, and the quieter months are the natural time to reseal. Blackness has two care or nursing homes no more than 2 miles away. In care settings, wet rooms, assisted bathrooms and en suites rely on clean, sound sealant. Each room is kept out of use only as long as the sealant needs.
For an occupier at a site such as Langsett Industrial Estate (0.6 miles south-east of Blackness), the canteen and welfare facilities need cleanable joints as much as any office. At a university such as University of Brighton Eastbourne Campus, 4.6 miles to the south of Blackness, summer is the usual window for resealing residence bathrooms.
