Remedial sealant in Horn Hill, done properly

A joint that keeps letting you down needs more than another bead. It helps to have pictures when you call 0345 464 0079 or send us an email. If you have floor or wall movement joints that have failed and repeat leaks from the same joint, we can put it right, on expansion joints, botched or over-sealed joints and mouldy bath & shower sealant alike.

In a village or hamlet like Horn Hill, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

Big or small, it’s backed by our 12-month guarantee.

Why act early in Horn Hill

Remedial work takes longer than a straight reseal, but not by much: it 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 Horn Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Landlords and agents in Horn Hill can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

What affects the cost of remedial sealant

We do not publish a price list, because jobs vary so much. The quote depends on:

  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • Any working-time requirements on site

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we need to know

You don’t need to know the technical terms. It helps if you can tell us:

  • The rough size of the job
  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel
  • Any previous sealing or DIY work

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.

Bathrooms and kitchens in Horn Hill

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

Schools such as Maple Cross Junior Mixed Infant and Nursery School are buildings too, and 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. For an older house near a landmark such as St Paul's, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Chorleywood station, botched sealant from a previous quick fix is easier to strip out between tenants.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

When it isn’t the sealant

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

  • A cracked shower tray or bath (that needs repair or replacing)
  • Older mastics that may need an asbestos check before removal
  • Movement from fittings that are not supported

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Where we work in Horn Hill

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

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Use a soft cloth, not a scourer, on silicone
  • Never fill a movement joint with mortar or grout
  • Act on a lifting corner straight away
  • Check ceilings under showers for marks

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. Each one is worth getting looked at.

The process

There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. Somewhere as small as Horn Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Old beads and residue are removed down to clean surfaces.
  3. Mould is treated and the joint dried.
  4. The right product goes in, with backing where the joint moves.
  5. We finish neatly and point out anything that needs another trade.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us if parking is tricky

Related advice

Horn Hill: your questions answered

Is Horn Hill within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

I let a flat near Chorleywood station. Can you help?

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

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can I choose the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

What sealant do you use?

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

Can you take off two layers of silicone?

Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.

How long will it take to strip and reseal the joint?

That depends on how many layers there are and how many joints. We’ll tell you before work begins.
