How to look after the new joints

A little care helps the new joints last. Our advice:

  • Use mild cleaners on sealant, not bleach or abrasives
  • Act on lifting sealant before it leaks
  • Put a squeegee in each shower
  • Book larger programmes for quieter times of year

Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix, and if anything looks wrong, just phone 0345 464 0079 or send us an email.

In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.

Commercial sealant in Slough Green

Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you are dealing with washroom sealant that looks dirty however often it’s cleaned and water marks on ceilings under bathrooms, we can help.

If you have holiday lets, a converted barn used for business or a community building near Slough Green, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Our work is backed for twelve months, in Slough Green and everywhere else we cover.

Leave it or put it right?

Refitting a washroom is a big, disruptive project. When the fittings are sound, renewing the sealant brings it back with far less upheaval. We will tell you if we find anything that needs another trade. Older cottages and farmhouses around Slough Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

What you get with us

  • Anti-fungal sanitary silicone in wet areas
  • 20+ years of sealant experience
  • A 12-month guarantee on all work
  • An ARBOMaster approved applicator

Slough Green questions

Do you cover Slough Green for commercial sealant?

Yes, Slough Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.

Will you come out to Slough Green?

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours per room, so whole buildings are phased. Somewhere like Slough Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start with a site walk to agree the rooms and the timing.
  2. Every area is sheeted and the old silicone stripped out.
  3. We clean the joints, treat any mould and let them dry.
  4. New sealant suited to each area is applied and tooled.
  5. We check every room and give its cure time for housekeeping.

Preparing for the visit

  • Clear the area around the work
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Rental portfolios

Between tenancies is a good time to reseal, ready for the next tenant.

Welfare facilities

Shower rooms in welfare blocks get heavy use and need sound joints. Anti-fungal sanitary silicone is used throughout, including accessible wet rooms.

What affects the quote in Slough Green

Jobs vary more than people expect. The main factors:

  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • Any mould that needs treating

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Asking for a quote

Before you ask for a quote, have a think about:

  • The type of property
  • The problem you’ve noticed
  • Whether it has been sealed before
  • A few photos by email, if you can

Honest limits

A few problems are outside what sealant work can do:

  • Fire risk assessments or certification
  • Poor ventilation that keeps bringing mould back
  • Failed tanking or loose tiles behind the sealant

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
