How the job changes by surface
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. We use anti-mould sanitary silicone throughout.
IPS and cubicle panels
Panel systems meet walls, floors and vanity tops at sealed joints. They stop water reaching the panel boards.

A 2-mile radius around Round Bush takes in several hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.

Why it’s worth doing now in Round Bush
Cleaning mouldy sealant only masks it, but the mould is rooted in the silicone and comes back. A full reseal deals with it and your cleaning team stops chasing it. Around Round Bush, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Would you work within a site like Spire Bushey Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

It depends on the product. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

Yes. We follow the specification, along with the manufacturer’s installation guidance.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is there a guarantee on the work?

Can you reseal washrooms in healthcare buildings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote before we start.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- The size and state of each joint
- Whether old sealant has to be cut out first
- Which sealant the job calls for
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Your programme or deadline
- What the building is and how it’s used
- A wide shot and a close-up of the area
- How the joints are reached, and at what height
