Looking after it afterwards

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

  • Use a soft cloth, not a scourer, on silicone
  • Keep movement joints clear of mortar and paint
  • Get the cause of a repeat leak found before resealing
  • Check ceilings under showers for marks

Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.

Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.

Remedial sealant in Blackboys

Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. We work on botched or over-sealed joints, shrunken worktop sealant and mouldy bath & shower sealant, and the jobs we see most are sealant that came away because the surface wasn’t prepared and sealant applied over old sealant that has lifted.

Around Blackboys, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How it works

We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours, depending on how many layers have to come out. In a small place like Blackboys, 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. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

Why it’s worth doing now in Blackboys

Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Around Blackboys, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

How much does remedial sealant cost in Blackboys?

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 you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What we can’t put right

A few problems are outside what sealant work can do:

  • Movement from fittings that aren’t supported
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Different surfaces, different methods

Worktops & kitchens

Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom.

Mouldy bath & shower sealant

Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
