What we are called out for in Holwell

One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.

Most people get in touch when they notice one of these:

  • Mould trapped under a layer of silicone
  • Movement joints that have split or pulled away
  • Worktop sealant that has shrunk and split
  • Beads that never stuck properly

Rented homes near Hitchin station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

  • Whether you can choose the colour
  • How the joint is cleaned and prepared

10 questions to ask before booking

How to look after the new joints

After the cure time, these simple habits help:

  • Keep an eye on the ceiling below the bathroom
  • Keep the room well ventilated
  • Do not wait for a small gap to become a leak
  • Keep bleach and abrasives off the bead

Keep the room ventilated: use the extractor or open a window after showering.

Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

The process

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the amount of work. Somewhere as small as Holwell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at how the sealant has failed and check for movement or a leak path.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. We use the right backing and sealant for any joint that moves.
  5. We tool the joint and tell you about anything else that needs attention.

Before we arrive

  • Clear the area around the work
  • Tell us about any water getting in
  • Keep pets and children clear of the area while we work

Holwell homes and their sealant

Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.

Schools such as The Priory School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around Church of St Peter (C of E) at Corner with Holwell Road, walls and floors in older homes can move, and sealant and grout show it first.

Landlord and commercial work in Holwell

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Why deal with it now?

It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Older cottages and farmhouses around Holwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

What the job involves on each surface

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.

Worktops & kitchens

If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
