When it is not the sealant

To be straight with you, there are a few things sealant will not fix:

  • Cracked trays or baths rather than failed joints
  • Leaking pipework, valves or wastes (a plumber’s job)
  • Fire risk assessments or certification

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

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

How we handle commercial sealant in Gibraltar

Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. Rooms are resealed in batches, so only a few are out of use at once. Typical jobs include leaking joints in shower rooms and changing areas and too many rooms to reseal without closing the building, on welfare facilities, rental portfolios and retail & leisure sites.

For holiday lets, converted business premises or a community building near Gibraltar, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Each job carries a 12-month guarantee, whatever its size.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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 does not work out, we can still put it right.

Landlord and commercial work in Gibraltar

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Workplaces and buildings in Gibraltar

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

For landlords with property near Haddenham & Thame Parkway station, sealant work can be quoted for a single flat or a whole portfolio. For buildings such as Church of Saints Peter and Paul, its kitchen and washroom sealant needs looking after like anywhere else.

How the visit works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours per area, with larger sites planned over several visits. Somewhere as small as Gibraltar, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. We let your team know the cure time for every area.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive

What affects the quote in Gibraltar

The price is agreed before any work begins. It’s based on:

  • The type of sealant required
  • Any working-time requirements on site
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What we need to know

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

  • Where the property is
  • Any access issues, like height or stairs
  • The rough size of the job
  • What’s wrong with the joints now

We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.

Common questions in Gibraltar

Will you come out to Gibraltar?

Yes, Gibraltar is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you do commercial sealant in Gibraltar?

Yes. Our work covers London and the South East, and Gibraltar is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

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 will say how long yours will take.

Does commercial work come with a guarantee?

Yes. Every job, domestic or commercial, carries our 12-month guarantee.

Do you provide RAMS?

Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we’ll confirm what we can provide when we quote.

Is it messy?

No. We protect the surfaces around the joints, and we tidy up before we go.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Log resealing so you know what’s due
  • Use mild cleaners on sealant, not bleach or abrasives
  • Keep extractor fans working and serviced
  • Plan resealing around quiet periods

Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and mould comes back faster without it.

Rooms out of use cost a hotel or landlord money. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.

What happens if it’s left?

Sealant work is quick by the room: it takes a few hours per room, so whole buildings are phased. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Older cottages and farmhouses around Gibraltar can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
