Commercial sealant around Alton

Alton has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

Community buildings like Church of St Lawrence are part of the picture too: any kitchen and washrooms need the same sealant care as any other building. For landlords with property near Alton station, several rental properties can be resealed on one programme. Schools such as Saint Lawrence Church of England Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Work for landlords, hotels and businesses

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

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes as long as the scope needs, from one welfare room to a full building and we leave things clean and tidy. For a job in Alton, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  1. The first visit is a look round the site to agree the scope.
  2. We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

How to prepare

  • Tell us about any water getting in
  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints

Different surfaces, different methods

Student & care accommodation

In care settings, we agree the order and timings with staff, with each bathroom handed back with its cure time.

Office washrooms & kitchens

Office washrooms and tea points are used all day, so we can work early or out of hours where that can be arranged. We reseal around basins, urinals, worktops and sinks.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

FAQs for Alton

Do you take on hotel work around Alton?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Do you cover Alton for commercial sealant?

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

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Do you work for landlords and letting agents?

Yes. Tell us the addresses and the rooms, and we will give you a clear price.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Does someone need to be in?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

How long do rooms need to be out of use?

Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.

When something else is needed

We will always be straight with you, so here’s what sealant can’t fix:

  • Water coming from plumbing rather than sealant
  • Cracked trays or baths rather than failed joints
  • Tiles coming off the wall

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.

What we seal

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

Why deal with it now?

Room by room, the work is quick: the job takes as long as the scope needs, from one welfare room to a full building. Each area is then left to cure for the time we give you, so the programme is planned around cure times. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Alton they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.

What it costs 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, so you know where you stand.

Why us?

  • Any old sealant cut out fully, not covered over
  • A choice of colours where the product allows
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Homes, businesses and hotels
