How we handle washroom sealing in Seven Dials
In a commercial washroom, sealant is typically the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. The fix is to remove it completely and reseal with sanitary silicone containing anti-mould additives. If you have failed sealant behind washroom basins and panel joints letting water behind, we can help, on IPS panels and cubicles, showers, trays and wet room floors and vanity units and basins alike. Searching for sealant specialists in Seven Dials? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Jobs in a smaller place such as Seven Dials are often one building: a school’s toilets, a café kitchen, a surgery’s washrooms. Photos of each area help us plan the visit and bring the right sealant.
A 12-month guarantee applies to all our work in Brighton and Hove. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we will come back to it.

Your questions answered
Does a hotel in Seven Dials need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Can you work around term dates at a campus such as University of Brighton Moulesecoomb Campus?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs usually get a visit.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- A room that stays damp because ventilation isn’t working
- Vanity carcasses that have swollen
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly.
Surfaces we seal
- Vanity units and basins
- Kitchens and tea points
- IPS panels and cubicles
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Urinals and WCs
Why deal with it now?
When a washroom looks worn, a refit isn’t the only answer. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Pricing washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Wet areas in Seven Dials’s workplaces
Seven Dials sits close to the coast, within about 1 mile, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Heavy seasonal use is hard on shower and basin sealant, and the quieter months are the natural time to reseal. The 2 miles around Seven Dials include five care or nursing homes. Care home wet rooms and en suites are used every day and cleaned hard, which tells on the silicone. We plan the work with the manager so residents are disturbed as little as possible.
Customer toilets in retail centres such as Churchill Square (to the south of Seven Dials) rarely close, so resealing is phased. At a hospital like The Montefiore Hospital (less than half a mile west of Seven Dials), patient and staff washrooms are best done in short phases agreed with the ward. On an industrial estate such as Centenary Industrial Estate (0.9 miles north-east of Seven Dials), staff toilets, showers and canteens are where sanitary sealant takes the most wear.

On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work. Work in places the size of Seven Dials is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- 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.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
Preparing the site
- Point out parking and an unloading spot
- Tell us which areas need to stay in use
- Let building users know which areas are affected
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
