How we handle remedial sealant in Preston

Remedial jobs in Preston generally fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. Typical jobs include repeat leaks from the same joint and worktop sealant that has shrunk and split, across shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints.

In a village or hamlet like Preston, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we do, step by step

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. In a small place like Preston, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we find out how and where the joint has failed.
  2. Every layer of old sealant is cut and cleaned out.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. The new joint is tooled neatly and we explain anything else we found.

Advice

When it is not the sealant

New sealant can’t fix everything, and we will tell you before work begins. Sealant will not put right:

  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
  • A cracked shower tray or bath (that needs repair or replacing)
  • A bath, tray or worktop that moves until it’s properly fixed

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Joints and surfaces we work on

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

Preston questions

Will you come out to Preston?

Yes, Preston is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

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

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Can you strip sealant from an acrylic tray safely?

Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.

Where do you work from?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

What does remedial sealant cost?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email with a short description of the job.

What information do you need?

A short description and the location. If we need more, we will ask.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. Our tips:

  • Deal with small splits early
  • Use a soft cloth, not a scourer, on silicone
  • Do not point over movement joints
  • Keep an eye on the ceiling below the bathroom

Keep the room ventilated: run the fan during and after showers, or open a window.

Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.

Landlords, agents and businesses in Preston

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

We also work for property managers and facilities teams in Preston and across Kent. We can quote a run of properties together, and we’re fully insured for the work.

What affects the quote in Preston

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether the work is at height
  • Whether there’s mould to deal with
  • The type of sealant required
  • The size of the job

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Helping us quote

Before you ask for a quote, have a think about:

  • Where the job is, and your postcode
  • If someone has resealed it before
  • How many joints, rooms or windows are involved
  • A few photos by email, if you can

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

DIY sealant or a professional job?

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 do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Remedial sealant in Preston: local notes

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

Managing a site like Preston Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Mildred include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

When to call us in Preston

Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.

Keep an eye out for these signs:

  • Worktop sealant that has shrunk and split
  • Leaks that keep coming back after resealing
  • Floor or wall movement joints that have failed
  • Thick, messy sealant smeared over tiles

Letting a property close to Adisham station? Then a joint that keeps failing is best fixed properly while the property is empty.
