About our remedial sealant in Burn's Green

If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. Common call-outs are for floor or wall movement joints that have failed and repeat leaks from the same joint, on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints.

Homes around Burn's Green are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.

You get a 12-month guarantee, the same in Burn's Green as everywhere else we work.

What happens on the day

You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. In a small place like Burn's Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We protect the surfaces around the joint.
  2. The botched or failed sealant is cut away completely.
  3. The joint is degreased and checked for movement and leaks.
  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

  • Clear the area around the work
  • Keep pets and children clear of the area while we work
  • Mention any parking rules near the property

Looking after it afterwards

After the cure time, these simple habits help:

  • Deal with small splits early
  • Report a tray that rocks or a worktop that lifts
  • Never seal over old silicone
  • Ask why a joint failed before redoing it

Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or drop us an email.

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

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The product the joint needs
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • The amount of work

Combining jobs into one visit normally makes better use of the time than several visits. We will give you a clear price for the lot.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • If someone has resealed it before
  • Any access issues, like height or stairs
  • Whether it’s a home or a business
  • Pictures of the joints, sent by email

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work before giving you a price.

Remedial sealant in Burn's Green: local notes

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.

For landlords with property near Watton-At-Stone station, a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Parish Church of St Peter, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do you need remedial sealant in Burn's Green?

Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.

Signs it’s time to call us include:

  • Smears and lumps from a botched reseal
  • Sealant applied over old sealant that has lifted
  • Repeat leaks from the same joint
  • Beads that never stuck properly

Managing a site like Benington Church of England Primary School? Then 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.

Choosing a sealant specialist

Why it’s worth doing now in Burn's Green

Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around Burn's Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Why Burn's Green clients choose us

  • We are fully insured
  • Tidy, careful work
  • Arbo and Everbuild products
  • A sealant colour to suit the surroundings
