Pirton Remedial Sealant

We cover Pirton for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

  • Over-sealed joints coming away
  • Thick, messy sealant smeared over tiles
  • Kitchen joints letting water behind the worktop

Remedial sealant for Pirton homes and businesses

Surface by surface

Mouldy bath & shower sealant

Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated.

Windows & doors

Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.

About our remedial sealant in Pirton

A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. If you’re dealing with repeat leaks from the same joint and torn expansion joints, we can help, whatever the surface.

For a small place like Pirton, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.

Our work is backed for twelve months.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

What sealant work can’t fix

It helps to know what we cannot do too:

  • Sealant in an older building that needs testing for asbestos first
  • Plumbing leaks behind walls or under trays
  • A tray or worktop that needs refixing first

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

Surfaces we seal

  • Botched or over-sealed joints
  • Failed movement joints
  • Shrunken worktop sealant
  • Leaking tray & enclosure joints
  • Mouldy bath & shower sealant
  • Expansion joints

For landlords and businesses

For anyone letting property in or around Pirton, jobs at different addresses can go on one quote. Send us the addresses and the work at each.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

How it works

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on how many layers have to come out in most cases. Somewhere as small as Pirton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

How to prepare

  • Clear items away from the joints we’re working on
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can

How to get a quote

We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.

Advice

What remedial sealant looks like in Pirton

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you live in an older home near Church of St Mary (Church of England), timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Pirton School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Hitchin station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What affects the quote in Pirton

There’s no set price list. What we look at:

  • Access and height
  • How much old sealant there is and how hard it is to remove
  • The size of the job

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Pirton questions

Can you help a landlord with a rental near Hitchin station?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Is Pirton in your area for remedial sealant?

Yes. We work across London and the South East, and Pirton is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.

How long does the work take?

A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.

Can failed expansion joints be resealed?

Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.

Someone sealed over the old bead. Can you fix it?

Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages.

Where is Mr Mastic based?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Can old silicone be taken off without scratching the tiles?

Yes. We take our time over removal, especially on acrylic, enamel and uPVC.

How to look after the new joints

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

  • Have loose fittings fixed before resealing
  • Never seal over old silicone
  • Don’t wait for a small gap to become a leak
  • Look for stains below bathrooms now and then

Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.

Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
