Remedial sealant in Jockey End

Remedial sealant in Jockey End

Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. If you are dealing with caulk or the wrong sealant used in a wet area and mould trapped under a layer of silicone, we can put it right, whatever the surface.

Around Jockey End, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.

There’s a 12-month guarantee on every job, whatever its size.

Why it’s worth doing now in Jockey End

DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Older cottages and farmhouses around Jockey End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

Jockey End: your questions answered

Do you work for landlords with property near Berkhamsted station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

Can you do remedial sealant in Jockey End?

Yes. Our work covers London and the South East, and Jockey End is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

Can I add another job to the visit?

Yes, we can. More than one area can be quoted together.

Can you take off two layers of silicone?

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

My shower still leaks after a reseal. Can you sort it?

Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.

What do you put in the joint?

Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.

Do you do commercial work?

Yes. We have worked for hotels, offices and other businesses and we’re fully insured.

Common problems we fix in Jockey End

Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.

Common reasons people contact us are:

  • Caulk or the wrong sealant used in a wet area
  • Movement joints that have split or pulled away
  • Wide, uneven beads that look worse than the old ones
  • Mould trapped under a layer of silicone

For site and facilities teams at buildings such as Gaddesden Row JMI School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Before booking anyone

  • The length of the guarantee
  • What happens if they find a problem under the old sealant
  • Which sealant they’ll use, and why
  • How the joint is cleaned and prepared

10 questions to ask before you book

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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

What the job involves on each surface

Worktops & kitchens

Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom.

Mouldy bath & shower sealant

Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Look for stains below bathrooms now and then
  • Air the bathroom so the sealant can dry
  • Check trays and worktops don’t move
  • Get the cause of a repeat leak found before resealing

If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.

Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.

When it is not the sealant

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

  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • Movement from fittings that are not supported
  • A tray or bath that is cracked

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

Where we work in Jockey End

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

The process

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Jockey End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you are told about anything else we found.

Before we arrive

  • Let us know about parking restrictions
  • Move anything stored near the joints
  • For indoor joints, keep the area dry beforehand if you can
