Washroom sealing near Burstow

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Burstow are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. The phasing is agreed so there are always facilities open.
  3. Failed silicone is removed completely and the surfaces cleaned of every trace.
  4. We clean and dry every surface so the new sealant can grip.
  5. We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
  6. Rooms reopen after the product’s cure time, and we move to the next.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we will be in
  • Move anything stored against the joints

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Washroom sealing in Burstow

Not every silicone belongs in a washroom. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you are dealing with shower tray joints that have opened up and users noticing mouldy joints, we can help, whatever the surface. Most enquiries from Burstow start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Community buildings around smaller places like Burstow have kitchens and toilets used by many people. Fresh anti-mould sanitary silicone at sinks, worktops and toilets keeps them cleanable.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Share your site rules when you send details
  • Don’t leave an open joint at a basin or tray
  • Brief cleaning staff to treat joints gently
  • Squeegee showers and trays after busy periods

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

Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.

Why it’s worth doing now in Burstow

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Converted and older buildings near places like Burstow tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Why us?

  • Health and safety: CHAS accredited
  • One number for every site we cover
  • Colours chosen to suit frames, cladding or finishes where possible
  • A range of standard colours, depending on the product

Cost factors for washrooms and wet areas

Each job is priced on its own details. The things that drive the figure:

  • Whether the work must be split into stages
  • How accessible the joints are
  • How much there is to seal
  • Removal of failed or old sealant

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send details through our quote form.

Questions we’re asked in Burstow

Does a hotel in Burstow need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Is Burstow too small for you to travel to?

No. Places such as Burstow are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

What sealant do you use in washrooms?

It depends on the joint. Most washroom joints take sanitary silicone while kitchens may need a food-safe grade.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can washrooms stay open while you work?

Only the area we’re working in is closed. Each room reopens after the sealant’s cure time, then we move on.

What if there’s asbestos in the old mastic?

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 work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

What we are called out for in Burstow

Low-level joints get hit by mop buckets, cleaning trolleys and feet, especially at floor edges and around urinals and WC pans.

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

  • Open joints along basins and vanity units
  • Sealant stained black around basins and showers
  • Complaints from staff, guests or users about tired washrooms
  • Shower tray joints that have opened up

Where you’re responsible for a hall attached to a building such as Church of St Bartholomew, its kitchen and toilets need sealant that stays cleanable.
