Washroom sealing for commercial buildings in St Katherines
We reseal washrooms and wet areas in offices, hotels, schools, universities, gyms, healthcare buildings and care homes, plus the kitchens and tea points that go with them. Product and method follow how hard each area is used and cleaned. We work on kitchens and tea points, showers, trays and wet room floors and urinals and WCs, and what we are called in for most is open joints at the base of cubicle panels and complaints from staff, guests or users about tired washrooms. Whoever orders the work in St Katherines, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Hospitality around smaller Scottish places like St Katherines tends to be seasonal, so washroom work is often best planned for quieter months.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Questions we are asked in St Katherines
Is a smaller place like St Katherines outside your area?
No. Places such as St Katherines are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Good photos up front let us bring everything on the first visit.
Will all the washrooms in our St Katherines building be closed at once?
Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Will cleaning remove black mould from sealant?
Usually not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacement is the lasting fix.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Why it’s worth doing now in St Katherines
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. Exposed buildings in Scotland take a lot of weather, and for a smaller place like St Katherines, a repair visit takes planning, so it’s better to act early.
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Condensation from failed extract fans
- Loose panels, vanity units or tiles, which need fixing first
- Failed tanking beneath a wet-room floor or behind tiles
If you’re not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.
What we seal

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Where we can, we combine work around St Katherines with other jobs nearby. Let us know if your dates have any give.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Old sealant is stripped and the faces prepared.
- The right sanitary or food-safe sealant is applied.
- We give you a reopening time for every room.
Before we start on site
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Share the asbestos register for older buildings

Maintenance after handover
After handover, a little attention goes a long way:
- Report faulty extraction promptly
- Don’t leave an open joint at a basin or tray
- Inspect washroom sealant regularly
- Clear standing water from shower floors where possible
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
Mould in a joint spreads along the bead and into nearby grout, and complaints follow. Replacing it early keeps the job to a reseal.
Do you need washroom sealing in St Katherines?
Warmth, moisture and soap residue are exactly what mould needs, and silicone joints hold onto all three. Anti-mould additives help, but in a poorly ventilated room mould can still take hold eventually.
Most enquiries start with one or more of the following:
- Sealant lifting along a tray edge
- Resealing that didn’t last because the old bead stayed
- Washrooms that look worn because of the sealant
- Failed sealant in a tea point or staff kitchen
Healthcare washrooms on sites such as House Of Daviot Hospital (to the south-west of St Katherines) are resealed area by area, under the site’s own infection-control rules.
What to look for in a quote
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will CSCS-carded applicators be on site?
- The named product and why it was chosen
- What site paperwork they can supply
