Washroom sealing in Ellesborough

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant so it returns whatever the cleaning regime. Only replacement gets rid of it for good. We work on vanity units and basins, accessible toilets and changing rooms and kitchens and tea points, and the usual reasons a site gets in touch are users noticing mouldy joints and black mould inside silicone joints that cleaning can’t shift. Searching for sealant specialists in Ellesborough? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Community buildings around smaller places like Ellesborough have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Your questions answered

Is a smaller place like Ellesborough outside your area?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can work at a site such as University Campus Aylesbury Vale fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What will the job cost?

There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Does the weather affect the 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. Inside work is seldom held up.

Which silicone is right for commercial washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone while kitchens may need a food-safe grade.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Ellesborough can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. Old sealant is removed completely and the faces cleaned.
  4. Each joint is cleaned and left dry.
  5. A sanitary silicone bead is laid and given a smooth tooled finish.
  6. Rooms reopen after the cure time.

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows
  • Flag any permit to work we will need

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • A dripping waste or valve behind a panel
  • Vanity carcasses that have swollen
  • Fittings that move too much to hold a bead

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

Surfaces we seal

  • IPS panels and cubicles
  • Kitchens and tea points
  • Vanity units and basins
  • Accessible toilets and changing rooms
  • Showers, trays and wet room floors
  • Urinals and WCs

Surface by surface

Healthcare and care settings

In healthcare, sealed joints are part of infection control. Your infection-control and estates rules are followed and any permits the site uses.

Basins and vanity tops

Vanity tops and basins are splashed all day, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.
