How we handle washroom sealing in Hinxworth
Closing all the facilities in a building isn’t an option. We phase the work one washroom, one bank of cubicles or one changing room at a time, so there are always facilities in use. Tell us your site hours and access windows and we will plan around them. If you’re dealing with sealant stained black around basins and showers and split or peeling sealant at shower trays, we can help. Searching for sealant specialists in Hinxworth? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Halls and community buildings near places like Hinxworth are used by different groups through the week, and their toilets and kitchens show it. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

General trades versus a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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.
Your questions answered
Do we have to close all our washrooms in Hinxworth for resealing?
Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Do you take on work at healthcare sites like Fairfield Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can you clean the mould off instead of resealing?
Usually not. Mould grows into the sealant itself so cleaning only lightens it for a while. Replacing the bead is the lasting answer.
Do you do washroom sealing in healthcare settings?
Yes. We work to your estates and infection-control requirements and any site permits. The work is phased around patients or residents.
Do you need to remove the old sealant?
The failed bead is always removed. New silicone won’t stick to the old, so sealing over it soon peels.
When can showers be used after new sealant?
That varies with the sealant and the room temperature. You will get a reopening time for each area, and signs stay up until then.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
What happens if it’s left?
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. Replacement deals with the cause in the joint and cleaners stop fighting a losing battle. For buildings around smaller places like Hinxworth, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Advice
Surface by surface
IPS and cubicle panels
A panel that has already swollen won’t be fixed by sealant and we’ll point out any we see.
Kitchens and tea points
In commercial kitchens, smooth, cleanable joints help keep the kitchen hygienic. Where food contact is possible, we use a hygienic, food-safe sealant.
