Different surfaces, different methods

Worktops & kitchens

If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, which we’ll point out.

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.

How we handle remedial sealant in High Cross

Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. If you are dealing with thick, messy sealant smeared over tiles and beads that never stuck properly, we can put it right, on botched or over-sealed joints, expansion joints and shrunken worktop sealant alike.

Somewhere as small as High Cross, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

Our work is backed for twelve months, in High Cross and everywhere else we cover.

High Cross homes and their sealant

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

Managing a site like Froxfield Church of England Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you let a flat or house near Petersfield station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Common questions in High Cross

Will you come out to High Cross?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you cover High Cross for remedial sealant?

Yes, High Cross is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.

How long will it take to strip and reseal the joint?

That depends on how many layers there are and how many joints. You will have a timescale before any work begins.

Is it messy?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

Can old silicone be taken off without scratching the tiles?

Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.

What sealant do you use?

Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. Our applicators cover High Cross.

What happens if the problem is the tray or the plumbing?

In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter.

What affects the quote in High Cross

For a quick quote, just ask. The main things that affect it are:

  • Any working-time requirements on site
  • The size of the job
  • How easy the joints are to reach
  • The product the joint needs

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • The address or postcode of the job
  • Any access issues, like height or stairs
  • How many joints, rooms or windows are involved
  • A few photos by email, if you can

We quote each job on its own, so start by telling us what you need. Simply call 0345 464 0079 or email us and describe the job, and photos are welcome.

Leave it or put it right?

Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a small place like High Cross, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why us?

  • 20+ years of sealant experience
  • 180+ five-star Google reviews
  • An ARBOMaster approved applicator
  • Anti-fungal silicone where joints get wet

What happens on the day

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like High Cross, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at how the sealant has failed and check for movement or a leak path.
  2. We strip the joint completely, removing any layers below.
  3. Next, any mould is treated and the joint dried.
  4. Moving joints get backing and a flexible sealant to suit.
  5. The new joint is tooled neatly and we explain anything else we found.

Preparing for the visit

  • Mention any tricky access
  • Let us know about parking restrictions
  • Tell us about any water getting in

Advice

For landlords and businesses

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

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Signs you need remedial sealant in High Cross

Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.

Common reasons people contact us include:

  • Black mould underneath the bead
  • A shower that leaks however often it’s resealed
  • A second bead peeling off the first
  • Kitchen joints letting water behind the worktop

For an older house near a landmark such as Church of St Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

  • Whether they seal over old material or remove it
  • How the colour is chosen
  • The length of the guarantee

Our hiring checklist

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Get the cause of a repeat leak found before resealing
  • Do not wait for a small gap to become a leak
  • Keep an eye on the ceiling below the bathroom
  • Always have old sealant cut out, not covered

Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just call 0345 464 0079 or email us.

Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
