Trusted remedial sealant in St Ibbs

Remedial sealant for homes and businesses in St Ibbs

Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we will tell you rather than reseal something that won’t fix it. If you’re dealing with smears and lumps from a botched reseal and mould trapped under a layer of silicone, we can put it right, on shrunken worktop sealant, leaking tray & enclosure joints and botched or over-sealed joints alike.

Somewhere as small as St Ibbs, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Never fill a movement joint with mortar or grout
  • Check trays and worktops do not move
  • Do not wait for a small gap to become a leak
  • Always have old sealant cut out, not covered

Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.

Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.

Honest limits

A few problems are outside what sealant work can do:

  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • Tiles that have come away from the wall
  • Cracks in the fitting rather than the joint

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Surfaces we seal

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

When to call us in St Ibbs

Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.

Signs it’s time to call us include:

  • Thick, messy sealant smeared over tiles
  • Sealant peeling off a dusty or damp surface
  • Products that weren’t meant for the joint
  • Floor or wall movement joints that have failed

In the older streets around Church of St Ippolyts (church of England), older homes can move a little, which is hard on rigid grout and tired sealant.

Before you book anyone

  • Who turns up on the day
  • What product goes in the joint

Our hiring checklist

St Ibbs: your questions answered

Is St Ibbs in your area for remedial sealant?

Yes, St Ibbs is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Do you cover smaller places like St Ibbs?

Yes, St Ibbs is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you reseal a split movement joint?

Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.

Can you remove sealant that is been put over old sealant?

Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.

Will you leave a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us and we’re fully insured.

Do you work for letting agents?

Yes, regularly. Several properties can go on one quote, and between tenancies is a good time for the work.

St Ibbs homes and their sealant

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.

For site and facilities teams at buildings such as St Ippolyts Church of England Aided Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Hitchin station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What happens if it’s left?

Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Where a wall is exposed, as many are in small places like St Ibbs, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Why book with us

  • We leave the area clean and tidy
  • Fully insured
  • Anti-fungal sanitary silicone in wet areas
  • Experience in homes, commercial sites and hotels

What we do, step by step

We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. The job generally takes a few hours, depending on how many layers have to come out. Somewhere as small as St Ibbs, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  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. You get the cure time and our view on why the joint failed.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in
  • Keep pets and children clear of the area while we work
