Questions about Dungate

Is a smaller place like Dungate outside your area?

Not at all. Dungate is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you plan work around the academic year at somewhere like Canterbury Christ Church University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact.

What sealant do you use in washrooms?

It depends on the joint. Washrooms and showers take anti-mould sanitary silicone, and food areas take a hygienic, food-safe sealant where food contact is possible.

Do you need washroom sealing in Dungate?

A lot of failed washroom sealant was laid over an old bead or a dirty surface. New silicone won’t grip the old, so it soon lets go.

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

  • Users noticing mouldy joints
  • Mould spotting along silicone joints
  • A new bead over an old one coming away
  • Stained or open joints at kitchen sinks and worktops

Church halls and community buildings, such as those at Church of St Catherine, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?

Our contractor checklist

What sets the cost

A fixed quote reflects the actual work. It allows for:

  • Site requirements such as inductions and permits
  • Whether old sealant has to be cut out first
  • Whether the work must be split into stages
  • Any access equipment needed

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What we need to price the job

However big the job, these details speed things up:

  • Any specification or named product
  • When you need the work done
  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Why deal with it now?

Washrooms shape how visitors judge a building. Visitors notice black sealant even when the room is otherwise spotless. Resealing is a modest task with a very visible payoff. One visit to deal with every failing joint makes more sense than several trips to a place like Dungate. Send photos of each area and we will quote for the lot.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why us?

  • CHAS accredited contractor
  • RAL and finish matching where the product range allows
  • Coloured sealants to suit the setting, where available
  • One phone line for London, the South East and Scotland

Take a look at what affects the cost and how we’re accredited.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For work around Dungate, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Every room is surveyed and the failed joints listed.
  2. The fixed quote sets out the rooms, the products and the phasing.
  3. The whole of the old bead is removed.
  4. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Rooms reopen after the cure time.

Preparing the site

  • Share your working hours and any access restrictions
  • Flag any permit to work we will need
  • Make sure the joints can be reached

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Fittings that move too much to hold a bead
  • Failed tanking beneath a wet-room floor or behind tiles
  • Panel boards already damaged by water

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

Surfaces we seal

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

Different surfaces, different methods

Kitchens and tea points

We plan kitchen sealing around when the kitchen is in use. Tell us your site hours and access windows and we’ll plan around them.

Healthcare and care settings

Clinics, hospitals and care homes need joints that can be kept clean. Your infection-control and estates rules are followed and any permits the site uses.
