Washroom sealing in Dungeness

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Common problems we fix in Dungeness

Warmth, moisture and soap residue are exactly what mould needs, and sealant joints trap all three. Even anti-mould grades can be colonised over time where extraction is poor.

Any of the following is a good reason to get the joints checked over:

  • Sealant laid over old silicone and now peeling
  • Stained sealant around pans and urinals
  • Mould spotting along silicone joints
  • Failed sealant behind washroom basins

For buildings around Dungeness, washrooms can be done in phases so some facilities are always open.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Health and safety accreditation such as CHAS
  • What site paperwork they can supply
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

Washroom sealing for commercial buildings in Dungeness

Black spotting along a sealant bead is not a cleaning problem. The growth is inside the sealant, which is why it comes back however often it is treated. Only replacement gets rid of it for good. We work on IPS panels and cubicles, vanity units and basins and urinals and WCs, and the usual reasons a site gets in touch are gaps where vanity tops meet the wall and resealing that didn’t last because the old bead stayed. Whoever orders the work in Dungeness, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Dungeness, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Dungeness clients

Which documents can you supply for work in Dungeness?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Is a smaller place like Dungeness outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is old silicone taken out first?

We strip every bit of the failed bead and wipe away the residue first. It’s the difference between a joint that lasts and one that peels.

How long before the toilets can reopen?

Cure times vary by product and temperature. You’ll get a reopening time for each area before we leave it.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

How a job runs

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Dungeness are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We inspect each washroom and record the joints to be resealed.
  2. You get a fixed quote with the phasing plan.
  3. The whole of the old bead is removed.
  4. Joints are degreased and dried.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

What we need from you

  • Point out parking and an unloading spot
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints

  • Mould caused by poor ventilation, which will return until the extract is fixed
  • Swollen or delaminated boards behind panels or vanity tops

Surface by surface

Wet-room floors and floor-to-wall joints

Wet-room floors and the joints where flooring turns up the wall need to stay sound. Floor perimeters and sealant joints near drains are resealed.

Kitchens and tea points

Staff kitchens and tea points have joints at worktops, sinks and splashbacks. Sound joints keep those surfaces easy to clean.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • Respect the cure time before reopening each room
  • Avoid scourers and harsh descalers on silicone
  • Inspect washroom sealant regularly
  • Note failing joints building by building

We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used, and it helps if signs stay up until then.

Boards behind panels and vanity tops can swell when water gets past a failed joint. After that, those parts need replacing rather than resealing.

Sanitary sealant for Dungeness buildings

With the shore within about 1 mile, Dungeness counts as a coastal location, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. Dungeness lies roughly 61 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.

Washrooms near Dungeness get the old silicone stripped out and a fresh anti-mould bead on dry joints.
