Diagnose, treat, sign off

Washroom sealing in Great Gaddesden
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels so they get particular attention. If you’re dealing with users noticing mouldy joints and failed sealant in a tea point or staff kitchen, we can put it right. Looking for mastic applicators who cover Great Gaddesden? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
Smaller places such as Great Gaddesden still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Do you need washroom sealing in Great Gaddesden?
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They aren’t made for constant wetting and they discolour and fail early.
Any of the following is a good reason to get the joints checked over:
- Sealant laid over old silicone and now peeling
- Urinal joints that look unhygienic
- Failed sealant in a tea point or staff kitchen
- Open joints along basins and vanity units
For a hall at a building such as Church of St John the Baptist, resealing the kitchen and toilets can be fitted between bookings.
Before you book anyone
- How long is the guarantee, and what does it include?
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?

Why deal with it now?
Washrooms shape how visitors judge a building. Guests, clients, pupils and patients notice stained joints before they notice much else. Fresh sanitary silicone lifts a room with very little disruption. One visit to deal with every failing joint makes more sense than several trips to a place like Great Gaddesden, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

What the job involves on each surface
Basins and vanity tops
Water getting past a vanity top joint can swell the board beneath. Resealing early protects the unit.
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.
What sets the cost
To price the job, we consider:
- Site requirements such as inductions and permits
- Any access equipment needed
- How much existing material needs removing
- Distance, for remote addresses
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Call for a quote.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The type of building and who uses it
- Access details, including height
- Asbestos survey details if the building is older
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Questions about Great Gaddesden
Is Great Gaddesden too small for you to travel to?
No. Places such as Great Gaddesden are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Hemel Hempstead Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Can you reseal washrooms in healthcare buildings?
We do. We work to your estates and infection-control requirements and any site permits, and phase the work so areas keep facilities.
How long before the toilets can reopen?
The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
What guarantee comes with washroom resealing?
Our workmanship has a 12-month guarantee backed by public liability insurance.
