Remedial sealant in Holbury

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How we handle remedial sealant in Holbury

Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you’re dealing with over-sealed joints coming away and decorators’ caulk around a bath or shower, we can help.

In and around Holbury, older properties sit alongside newer ones. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.

Whatever the size of the job, it’s backed by our 12-month guarantee in Holbury and across Hampshire.

Surface by surface

Worktops & kitchens

Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed.

Over-sealed & botched joints

A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.

Holbury: your questions answered

Do you work in hotels near Holbury?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

What if the leak isn’t the sealant?

We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

Can you strip sealant from an acrylic tray safely?

Yes. We take our time over removal, especially on acrylic, enamel and uPVC.

Can failed expansion joints be resealed?

Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Report a tray that rocks or a worktop that lifts
  • Ask why a joint failed before redoing it
  • Deal with small splits early
  • Keep an eye on the ceiling below the bathroom

Where we’ve pointed out another fault, have it put right, or the new joint may fail again.

Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.

When something else is needed

We will not take on work that will not last, so these are the limits:

  • A tray or worktop that needs refixing first
  • A leaking trap, valve or supply pipe
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

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

Joints and surfaces we work on

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

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What happens if it’s left?

A failed seal rarely means a new bathroom. When the fittings are sound, stripping and resealing the joints is often enough. Where something else has failed, you will hear it from us. Homes in smaller places like Holbury can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.

What we do, step by step

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Holbury, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  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. New sealant goes in once the joint is dry, and is tooled smooth.
  5. We give you the cure time and explain what caused the failure.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any water getting in
  • Keep pets and children clear of the area while we work
