Common questions from Eastwood clients

Is Eastwood too far out for you?

Not at all. Eastwood is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

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

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Do you need to remove the old sealant?

We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

Do you need to see the site first?

That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs usually get a visit.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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.

What do you charge?

We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.

Can one quote cover more than one building?

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

Washroom sealing in Eastwood

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so there are always facilities in use. Tell us your site hours and access windows and we’ll plan around them. Site teams most often ask us about shower tray joints that have opened up and washrooms that look worn because of the sealant, across IPS panels and cubicles, vanity units and basins and kitchens and tea points. A specialist sealant contractor works differently from a general builder: on jobs in Eastwood, preparation and product choice get the time they need.

In and around places like Eastwood, hospitality kitchens and toilets see heavy use in busy spells. Smooth, sealed joints at worktops, sinks and wall cladding make cleaning easier, using a food-safe product near food preparation.

Work we carry out in Southend-on-Sea comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

What we can’t put right

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Swollen or delaminated boards behind panels or vanity tops
  • Condensation from failed extract fans
  • Water from plumbing, not from a joint

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

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

Leave it or put it right?

Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Small buildings around Eastwood suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

A quote for washrooms and wet areas depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Why appoint us

  • One phone line for London, the South East and Scotland
  • Clear, fixed quotes
  • Old sealant cut out, never sealed over
  • Products installed to the manufacturer’s instructions

Common problems we fix in Eastwood

Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.

Look out for the following:

  • Open joints at the base of cubicle panels
  • Complaints from staff, guests or users about tired washrooms
  • Sealant stained black around basins and showers
  • Stained sealant around pans and urinals

For an occupier at a site such as Laurence Industrial Estate, which lies east of Eastwood, the canteen and welfare facilities need cleanable joints as much as any office.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?
  • Proof of insurance
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Toilets, showers and kitchens around Eastwood

Eastwood is within about 3 miles of the coast, and coastal hotels, guest houses and holiday sites tend to fill up in the busy months. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. Eastwood has several hotels close by, all within 2 miles. Behind every hotel door there’s a bathroom whose sealant will need renewing sooner or later. The work can go floor by floor, agreed with housekeeping.

Halls of residence and teaching buildings at universities such as University of Essex, 3 miles to the south-east of Eastwood, are easiest to reseal during vacations. For a college such as South Essex College Stephenson Road Campus, which lies west of Eastwood, half-term and summer give the windows for washroom work.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. What matters most for a job in Eastwood is a clear list of what needs doing. A fixed quote follows.

  1. We survey each room, count the joints and note anything behind them that needs another trade.
  2. A phasing plan keeps part of the building’s facilities in use at all times.
  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. Each room is handed back once the sealant has had its cure time.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Point out any areas we must not close

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Maintenance after handover

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep washrooms out of use until we say the sealant has cured
  • Avoid scourers and harsh descalers on silicone
  • Keep extract fans working and vents clear
  • Share your site rules when you send details

Add washroom sealant to routine inspections. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and log what you find.

Water getting behind IPS panels and vanity units can swell the boards. Once that happens, a reseal won’t fix them.
