Washroom sealing in Gladsmuir
For clinics, hospitals and care homes, sealed joints matter for infection control as much as appearance. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Any records you need are confirmed with the quote. Site teams most often ask us about black mould inside silicone joints that cleaning can’t shift and a new bead over an old one coming away, across showers, trays and wet room floors, accessible toilets and changing rooms and kitchens and tea points. Searching for sealant specialists in Gladsmuir? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places such as Gladsmuir, washrooms and kitchens are found in hotels, pubs, schools, care homes and halls. Black sealant usually can’t be cleaned, so it is removed and replaced with anti-mould sanitary silicone.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Aftercare for building managers
For the best life from the joints:
- Clear standing water from shower floors where possible
- Clean sealant with gentle products and a soft cloth
- Share your site rules when you send details
- Keep a record of which washrooms need attention
Squeegeeing showers and trays after heavy use helps. Joints that sit wet for hours fail sooner.
Water getting behind IPS panels and vanity units can swell the boards. After that, those parts need replacing rather than resealing.
Signs you need washroom sealing in Gladsmuir
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting, and they stain, crack or wash out.
Clients typically get in touch after noticing one or more of the following:
- Sealant laid over old silicone and now peeling
- Users noticing mouldy joints
- Failed sealant behind washroom basins
- Failed joints along IPS and cubicle panels
For a hall at a building such as Gladsmuir Parish Church, resealing the kitchen and toilets can be fitted between bookings.
Before you book anyone
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
- Whether their applicators hold CSCS cards
- How joint depth will be controlled
Leave it or put it right?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and your cleaning team stops chasing it. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Your questions answered
Will the toilets in our Gladsmuir building be out of use?
Usually only some of them, for a short time. We work in phases so other facilities stay open. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Is a hospital such as East Lothian Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long before the toilets can reopen?
Cure times vary by product and temperature. Each room gets its own reopening time from us before we leave it.
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 check the ventilation isn’t the cause.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Does weather matter for sealant work?
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.
Quoting for work in Gladsmuir

The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sanitary sealant for Gladsmuir buildings
Gladsmuir sits close to the coast, within about 3 miles, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, so we plan the work for quieter weeks where possible. Gladsmuir is in the east of Scotland, which is drier than the west. Even so, a washroom that doesn’t dry out between uses will see mould get into its sealant.
At a hospital like East Lothian Community Hospital, 2.6 miles east of Gladsmuir, patient and staff washrooms are best done in short phases agreed with the ward. Welfare facilities in units on estates such as Macmerry Industrial Estate, 1.2 miles west of Gladsmuir, have showers, toilets and kitchens with sealant that works hard.

Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
