Common questions in Westcombe Park

Do you work for landlords with property near Westcombe Park station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is parking an issue for remedial sealant in Westcombe Park?

Parking in Westcombe Park, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

What if the leak is not the sealant?

We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we won’t pretend it will.

Can I do 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.

Where do you work from?

We’re based in Crawley, and we work across South East England, London and Scotland.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Which products do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.

How long should I leave it?

That depends on the sealant used, so follow the cure time we give you when we finish.

Remedial sealant in Westcombe Park

If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on expansion joints, failed movement joints and leaking tray & enclosure joints, and common reasons people get in touch are repeat leaks from the same joint and caulk or the wrong sealant used in a wet area.

London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Westcombe Park more than a cosmetic job.

We stand behind the work with a one-year guarantee.

Westcombe Park homes and their sealant

In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. There are hotels and other places to stay in and around Westcombe Park. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

Managing a site like Halstow Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to St George's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Letting a property close to Westcombe Park station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Westcombe Park is about 2 miles east of New Cross, in Greater London. Across the SE10 area, we can carry out remedial sealant at your property. Westcombe Park is one of 764 towns and villages in Greater London we cover for remedial sealant.

Quotes for remedial sealant in Westcombe Park

We do not publish a price list, because jobs vary so much. What we look at:

  • Any working-time requirements on site
  • How many areas need sealing
  • The product the joint needs
  • Any mould that needs treating

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • If someone has resealed it before
  • Whether it’s a home or a business
  • How we’d reach the joints
  • Photos by email, if that is easy

To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

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 fails, we can still redo it.

Why deal with it now?

Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. 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.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How the visit works

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours for most joints, depending on how much old sealant has to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Westcombe Park. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  3. We clean and degrease the joint and look for signs of movement or water.
  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.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any sign-in or site rules at work premises
  • Keep pets and children clear of the area while we work

How the job changes by surface

Over-sealed & botched joints

Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.

Leaking trays & enclosures

A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before any new sealant goes on.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Have loose fittings fixed before resealing
  • Deal with small splits early
  • Do not add new sealant on top of old
  • Keep the room well ventilated

Don’t let anyone seal over it later. New silicone doesn’t bond to old.

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

When something else is needed

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

  • A cracked shower tray or bath (that needs repair or replacing)
  • Water damage behind tiles that needs a tiler
  • Sealant in an older building that needs testing for asbestos first

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
