Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • A tray or worktop that needs refixing first
  • Water damage behind tiles that needs a tiler
  • A cracked shower tray or bath (that needs repair or replacing)

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

Joints and surfaces we work on

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

Remedial sealant in Seasalter, done properly

Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on expansion joints, shrunken worktop sealant and botched or over-sealed joints, and the jobs we see most are sealant that came away because the surface wasn’t prepared and decorators’ caulk around a bath or shower.

Around Seasalter, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.

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.

Do you need remedial sealant in Seasalter?

Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.

If you can see any of these, it’s time to have the joints looked at:

  • Torn expansion joints
  • Worktop sealant that has shrunk and split
  • A second bead peeling off the first
  • A shower that leaks however often it’s resealed

Schools such as Joy Lane Primary Foundation School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Questions from Seasalter

Do you cover smaller places like Seasalter?

Yes. Seasalter is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you do remedial sealant in Seasalter?

Yes, Seasalter is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

What if resealing will not fix my leak?

Then we explain what we have found. A plumber or fitter may be needed before any new sealant goes on.

Can you take off two layers of silicone?

Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.

Do you guarantee remedial jobs?

Yes, for 12 months. If we’ve pointed out another problem, getting it fixed helps the new joint last.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

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.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

Remedial sealant around Seasalter

Seasalter is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, 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, and it has to be cleaned off before new sealant goes in.

If you live in an older home near Seasalter Christian Centre, walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Whitstable station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

DIY sealant or a professional job?

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

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Why it’s worth doing now in Seasalter

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. It’s far less disruption than resealing the same joint again and again. Older cottages and farmhouses around Seasalter can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Why us?

  • We leave the area clean and tidy
  • ARBOMaster approved applicator

  • A choice of colours where the product allows

The process

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours, depending on how many layers have to come out from start to finish. Somewhere as small as Seasalter, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. All the old sealant comes out, including any layers underneath.
  3. We clean the joint, treat any mould and let it dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. We tool the joint and tell you about anything else that needs attention.

Getting ready for the visit

  • Move anything stored near the joints
  • Tell us about any previous sealing or DIY attempts
  • Mention any parking rules near the property

Aftercare tips

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

  • Don’t add new sealant on top of old
  • Air the bathroom so the sealant can dry
  • Keep movement joints clear of mortar and paint
  • Report a tray that rocks or a worktop that lifts

If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.

Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
