Remedial sealant in Pinner

A joint that keeps letting you down needs more than another bead. It helps to have photos when you call 0345 464 0079 or email us, and say how long ago it was last done. We work on leaking tray & enclosure joints, expansion joints and mouldy bath & shower sealant, and common reasons people get in touch are gaps opening along the back of the worktop and sealant that came away because the surface wasn’t prepared.

In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Pinner are no different.

There’s a 12-month guarantee on every job, whatever its size.

Quotes for remedial sealant in Pinner

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint
  • Mould in or behind the old joints
  • The number of rooms or windows

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Where the property is
  • The rough size of the job
  • The type of property
  • A few photos by email, if you can

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you are ready, phone 0345 464 0079 or send us an email.

What the job involves on each surface

Movement & expansion joints

A sealant stuck to the back of the joint cannot stretch. Backing stops that, letting the sealant flex between the two faces.

Mouldy bath & shower sealant

Repeat mould normally points to a damp, poorly aired room. We’ll reseal and tell you if extraction looks to be the issue.

Signs you need remedial sealant in Pinner

Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

If you can see any of these, it’s time to have the joints looked at:

  • Sealant that came away because the surface wasn’t prepared
  • Worktop sealant that has shrunk and split
  • Floor or wall movement joints that have failed
  • Dark patches showing through the sealant

If you look after a building such as West Lodge Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Our hiring checklist

Bathrooms and kitchens in Pinner

London’s water is hard, which leaves limescale on sealant, grout and taps. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.

Rented homes near Hatch End station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you live in an older home near Christian Science Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

When it is not the sealant

To be straight with you, there are a few things sealant will not fix:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Tiles that have come away from the wall
  • A leaking trap, valve or supply pipe

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Where we work in Pinner

  • Botched or over-sealed joints
  • Failed movement joints
  • Mouldy bath & shower sealant

Leave it or put it right?

DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Pinner.

What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before any work starts.

Pinner: your questions answered

I let a flat near Hatch End station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Is parking a problem for a job in Pinner?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Where are you based?

Our base is Crawley. We work across South East England, London and Scotland.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

What sealant do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Do you take out the old sealant first?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

How long does remedial resealing take?

That depends on how many layers there are and how many joints. You will have a timescale before any work begins.

Can old silicone be taken off without scratching the tiles?

Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

How it works

When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Pinner. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. We clean the joint, treat any mould and let it dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. We tool the joint and tell you about anything else that needs attention.

Getting ready for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • On commercial sites, let us know about site rules
  • Let us know about earlier repairs to the joints
