Crawley questions

Do older homes in Crawley need their sealant replacing?

Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant will not bond to it.

Can you help a landlord with a rental near Crawley station?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.

What should I tell you?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned.

Is it worth trying 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.

Will it make a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Will there be a smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Someone sealed over the old bead. Can you fix it?

Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.

Remedial sealant for homes and businesses in Crawley

In Crawley, as anywhere, remedial jobs tend to look alike: 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. If you’re dealing with over-sealed joints coming away and mould trapped under a layer of silicone, we can put it right.

Crawley is big enough to have housing from every era, from period houses to modern flats and estates. Whatever the age of the home, sealant and grout in bathrooms and kitchens wear out in the end.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

What affects the cost of remedial sealant

There’s no set price list. What we look at:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • Any working-time requirements on site
  • Whether there’s mould to deal with

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.

Asking for a quote

You do not need to know the technical terms. Just tell us:

  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any access issues, like height or stairs
  • Pictures of the joints, sent by email

We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

How the visit works

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. Commercial jobs in Crawley can be planned out of hours where a building can’t close, while home visits are arranged within our normal working hours, Monday to Saturday.

  1. Surrounding tiles, trays and frames are protected first.
  2. The botched or failed sealant is cut away completely.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work
  • Clear the area around the work

Advice

Signs you need remedial sealant in Crawley

One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.

People usually contact us when they notice something like this:

  • Torn expansion joints
  • Dark patches showing through the sealant
  • Thick, messy sealant smeared over tiles
  • Sealant applied over old sealant that has lifted

Rented homes near Crawley station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

What to look for in a quote

  • Are they insured?
  • What preparation is included
  • Whether VAT is included
  • Which colour the sealant will be

Choosing a sealant specialist

What we cannot put right

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

  • Failed tanking or loose tiles behind the sealant
  • Sealant in an older building that needs testing for asbestos first
  • Cracks in the fitting rather than the joint

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

Where we work in Crawley

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

Remedial sealant in Crawley: local notes

Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Crawley was built as one of England’s post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. New sealant won’t stick to old, so the old layers have to come out first.

Schools such as Three Bridges Junior School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Friary Church of St Francis and St Anthony include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Keep movement joints clear of mortar and paint
  • Deal with small splits early
  • Keep bleach and abrasives off the bead
  • Report a tray that rocks or a worktop that lifts

Clean gently: no scraping, scouring pads or harsh chemicals.

Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
