Aftercare tips

To keep the joints looking good and working properly:

  • Give housekeeping the cure time for every room
  • Act on lifting sealant before it leaks
  • Plan resealing around quiet periods
  • Use mild cleaners on sealant, not bleach or abrasives

Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.

Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, instead of turning into a leak that closes the room.

What the job involves on each surface

Rental portfolios

Good sealant prevents leaks that cause bigger repairs.

Student & care accommodation

Vacant rooms make resealing quick and simple.

FAQs for Wallington

Do you work in hotels near Wallington?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Is parking a problem for a job in Wallington?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

What information do you need?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Do you guarantee your work?

Yes. Each job is guaranteed for twelve months, large or small.

Can you seal over the old sealant?

No. We remove every bit of old sealant first, so the new sealant bonds properly.

How long does the job take?

As a guide, most jobs take as long as the scope needs, from one welfare room to a full building. Bigger jobs take longer, and we’ll tell you how long to expect.

When can guests or staff use the shower again?

Most areas can be used after around 24 hours. We give a cure time for each area.

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of rooms in most cases. In Wallington, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before we start.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Rooms are handed back in order, each with its cure time.

Getting ready for the visit

  • Mention any parking rules near the property
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Advice

Signs you need commercial sealant in Wallington

Plenty of commercial bathrooms have no window at all, so if the fan is weak, steam lingers and the sealant stays damp. Mould then takes hold in the silicone.

The most common problems we see are:

  • Leaking joints in shower rooms and changing areas
  • Large numbers of bathrooms needing the same work
  • Silicone laid over old silicone by a previous contractor
  • Failed joints in office kitchens and tea points

If you look after a church, hall or community building such as Church of the Holy Trinity, its kitchen and washroom sealant needs looking after like anywhere else.

Choosing a sealant specialist

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Poor ventilation that keeps bringing mould back
  • Water damage behind the tiles that needs a tiler or builder
  • Damaged sanitaryware that needs replacing

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Surfaces we seal

  • Rental portfolios
  • Office washrooms & kitchens
  • Hotel bathrooms
  • Student & care accommodation
  • Retail & leisure sites
  • Welfare facilities

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
