What affects the quote in Beckenham

Your quote is based on your job. We take into account:

  • How easy the joints are to reach
  • The size of the job
  • The old material and how stubborn it is
  • Any working-time requirements on site

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

When you contact us, these details help:

  • The address or postcode of the job
  • If someone has resealed it before
  • The type of property
  • Any access issues, like height or stairs

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

How we handle remedial sealant in Beckenham

Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have wide, uneven beads that look worse than the old ones and caulk or the wrong sealant used in a wet area, we can put it right, whatever the surface.

Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Beckenham more than a cosmetic job.

A one-year guarantee comes as standard, so you are covered after we have gone.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Have loose fittings fixed before resealing
  • Use a soft cloth, not a scourer, on silicone
  • Check ceilings under showers for marks
  • Don’t point over movement joints

Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or send us an email.

Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.

Beckenham 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. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Homes close to Christ Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Beckenham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

For landlords and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What the job involves on each surface

Mouldy bath & shower sealant

Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.

Over-sealed & botched joints

Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.

Should I try it myself first?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What happens on the day

The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. In a London area like Beckenham, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  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.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Try not to wet indoor joints just before the visit
  • Plan for the work area to be out of bounds to pets and children

What we’re called out for in Beckenham

All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. At that point it has to come out.

Common reasons people contact us are:

  • Decorators’ caulk around a bath or shower
  • Mould trapped under a layer of silicone
  • Smears and lumps from a botched reseal
  • Sealant that came away because the surface wasn’t prepared

For landlords with property near Beckenham Junction station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Before you book anyone

  • Whether they seal over old material or remove it
  • What the cure time is
  • Whether you can choose the colour
  • How the surfaces are prepared before sealing

Our hiring checklist

Questions from Beckenham

I live in a flat in Beckenham. Can a failed seal leak into the flat below?

It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.

Do you work for landlords with property near Beckenham Junction station?

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

My shower still leaks after a reseal. Can you sort it?

Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.

Will the old sealant be removed?

Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

Can failed expansion joints be resealed?

Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.

When is the sealant fully cured?

It depends on the product and the temperature. We tell you how long to leave it before we go.

Which products do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
