Remedial sealant in Breachwood Green, done properly

Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. We work on botched or over-sealed joints, expansion joints and failed movement joints, and people most often call us about mould trapped under a layer of silicone and wide, uneven beads that look worse than the old ones.

Homes around Breachwood Green are mostly 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.

Big or small, you get the same 12-month guarantee.

Breachwood Green questions

Can you help a landlord with a rental near Luton Airport Parkway station?

Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Do you cover smaller places like Breachwood Green?

Yes, Breachwood Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

What if the leak isn’t the sealant?

We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we will not reseal for the sake of it.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.

Are you fully insured?

Yes. We are fully insured for every job we do.

Can you take off two layers of silicone?

Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Always have old sealant cut out, not covered
  • Deal with small splits early
  • Keep movement joints clear of mortar and paint
  • Ask why a joint failed before redoing it

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.

What affects the cost of remedial sealant

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Any working-time requirements on site
  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Whether it has been sealed before
  • The problem you’ve noticed
  • Where the property is
  • Pictures of the joints, sent by email

For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.

Signs you need remedial sealant in Breachwood Green

A lot of failed joints have been sealed over rather than replaced. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.

Keep an eye out for these signs:

  • A shower that leaks however often it’s resealed
  • Movement joints that have split or pulled away
  • Caulk or the wrong sealant used in a wet area
  • Sealant that came away because the surface wasn’t prepared

Managing a site like Breachwood Green Junior Mixed and Infant School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Choosing a sealant specialist

Remedial sealant around Breachwood Green

If you live in an older home near Church of St Mary, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Luton Airport Parkway station, botched sealant from a previous quick fix is easier to strip out between tenants.

Honest limits

In fairness, some problems need a different trade:

  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • A tray or worktop that needs refixing first
  • Failed tanking or loose tiles behind the sealant

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What we seal

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

How the job changes by surface

Mouldy bath & shower sealant

Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.

Movement & expansion joints

Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

The process

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Breachwood Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
  • Try not to wet indoor joints just before the visit
