Trusted remedial sealant in Southfields

Remedial sealant for homes and businesses in Southfields

Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and the jobs we see most are a second bead peeling off the first and products that weren’t meant for the joint.

Around Southfields, it’s houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.

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

What happens on the day

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. For a village or hamlet like Southfields, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. We finish neatly and point out anything that needs another trade.

Advice

What affects the quote in Southfields

The price is agreed before any work begins. It takes into account:

  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises
  • Access and height
  • How many areas need sealing

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • The type of property
  • How many joints, rooms or windows are involved
  • If someone has resealed it before
  • Where the job is, and your postcode

To get a quote, phone 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before we start.

For landlords and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Remedial sealant in Southfields: local notes

Southfields is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For site and facilities teams at buildings such as Orsett Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near St Giles & All Saints Church, older homes can move a little, which is hard on rigid grout and tired sealant.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Get the cause of a repeat leak found before resealing
  • Never seal over old silicone
  • Report a tray that rocks or a worktop that lifts
  • Never fill a movement joint with mortar or grout

If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.

Warning signs: 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.

What the job involves on each surface

Mouldy bath & shower sealant

Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.

Movement & expansion joints

Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.

What sealant work can’t fix

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

  • Failed tanking or loose tiles behind the sealant
  • Leaks from a shower valve, waste or pipework (a plumber’s job)
  • Movement from fittings that are not supported

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

Where is Mr Mastic based?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you fix expansion and movement joints?

Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.

How long before the joint can be used?

Different products cure at different speeds, so follow the cure time we give you.

Do you work for letting agents?

Yes, we do. We work in homes, commercial premises and hotels.

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

A little longer than a standard reseal. For most joints, it’s a few hours.

Which products do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.

Signs you need remedial sealant in Southfields

Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.

Any of these means the joints need attention:

  • Black mould underneath the bead
  • Caulk or the wrong sealant used in a wet area
  • A shower that leaks however often it’s resealed
  • Sealant applied over old sealant that has lifted

If you let a flat or house near Stanford-Le-Hope station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
