How we handle remedial sealant in Seaford

Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you have wide, uneven beads that look worse than the old ones and dark patches showing through the sealant, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and mouldy bath & shower sealant alike.

Plenty of homes in a town like Seaford have had new bathrooms and kitchens over the years, some more than once. Sealant run over the top of an old bead is a common cause of leaks and mould, so we take every joint back to clean before anything new goes in.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods

Windows & doors

A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.

Mouldy bath & shower sealant

Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.

Do you need remedial sealant in Seaford?

Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.

These are the problems we’re asked about most:

  • Movement joints that have split or pulled away
  • Sealant peeling off a dusty or damp surface
  • Worktop sealant that has shrunk and split
  • Wide, uneven beads that look worse than the old ones

Letting a property close to Seaford station? Then a joint that keeps failing is best fixed properly while the property is empty.

Before you book anyone

  • What product goes in the joint
  • The length of the guarantee
  • Which colour the sealant will be
  • Who does the work, and how experienced they are

Choosing a sealant specialist

What we can’t put right

It helps to know what we can’t do:

  • A bath, tray or worktop that moves until it’s properly fixed
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • Water damage behind tiles that needs a tiler

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

Joints and surfaces we work on

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

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Find out why the sealant failed first
  • Look for stains below bathrooms now and then
  • Air the bathroom so the sealant can dry
  • Report a tray that rocks or a worktop that lifts

Where we have pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.

Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Why act early in Seaford

DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Seaford, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

  • Sanitary silicone with an anti-fungal additive in wet areas
  • 4.9 on Google from 180+ five-star reviews
  • White, clear, grey or coloured to suit, where the product allows
  • Full insurance on every job

Can you do several jobs on one visit?

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Remedial sealant around Seaford

Seaford is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

If you live in an older home near Church of St Thomas More, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Seaford Primary School, 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.
