Twitton: questions and answers

Do hotels near Twitton have to close for sealant work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Is hospital work, at somewhere like Sevenoaks Hospital, something you do?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Is old silicone taken out first?

We always remove it. New silicone won’t stick to the old, so sealing over it soon peels.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Washroom sealing in Twitton, done properly

In a busy washroom, the sealant typically gives up long before the tiles or fittings. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about open joints at the base of cubicle panels and discoloured joints around urinals and WC pans, on showers, trays and wet room floors, urinals and WCs and accessible toilets and changing rooms. Facilities teams, main contractors and managing agents in Twitton tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Farm shops, cafés and venues in converted rural buildings around places like Twitton have busy toilets and kitchens. We plan the work around bookings and opening times.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Tell us about infection-control or permit rules before we quote
  • Include joints in routine washroom inspections
  • Report faulty extraction promptly
  • Leave signs up until the cure time is over

If a joint we sealed fails within 12 months, tell us and we’ll look at it. Beyond that, regular checks keep small problems small.

Small numbers of failed joints are quick to phase in. Left until every washroom is affected, it becomes a bigger programme with more phasing to plan.

When to call us in Twitton

We often find acrylic caulk or general-purpose sealant in joints that should have sanitary silicone. They aren’t made for constant wetting and they discolour and fail early.

These are often picked up first by site or facilities staff:

  • Gaps where vanity tops meet the wall
  • Kitchen worktop joints that can’t be kept clean
  • Sealant lifting along a tray edge
  • Black mould inside silicone joints that cleaning can’t shift

Pupil toilets at schools like Otford Primary School take heavy daily use, and the holidays give the window to reseal.

Questions to ask before you book

  • How joint depth will be controlled
  • How they handle RAMS and site documents
  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long

Leave it or put it right?

Waiting for a holiday closure can leave failing joints in place for a long time. With phasing, the work can go ahead while most facilities stay open. Older rural buildings around Twitton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Why us?

  • CSCS-carded applicators
  • Colour agreed before work starts
  • Over 20 years of commercial sealing

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes half a day to a day per washroom, depending on the number of fittings, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Twitton are usually planned as a single visit, so we ask for photos and rough sizes first. 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. Each joint is cleaned and left dry.
  5. New anti-mould sealant goes in and is tooled neat.
  6. Each area is handed back when ready.

Getting the site ready

  • Have the specification and drawings to hand
  • Arrange parking or a loading space
