Remedial sealant near Bromley

Remedial sealant for homes and businesses in Bromley

In Bromley, 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. We’re often asked to deal with floor or wall movement joints that have failed and decorators’ caulk around a bath or shower, across leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints.

For a small place like Bromley, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.

All our work comes with our 12-month guarantee, wherever you are in Hertfordshire.

How the visit works

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Bromley, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
  2. Each layer is cut out and the residue cleaned off.
  3. Mould is treated and the joint dried.
  4. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you’re told about anything else we found.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Tell us if parking is tricky
  • Clear the area around the work

When it is not the sealant

We’ll always be straight with you, so here’s what new sealant will not do:

  • Tiles that have come away from the wall
  • Sealant in an older building that needs testing for asbestos first
  • A cracked shower tray or bath (that needs repair or replacing)

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

What we seal

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

Work for landlords, hotels and businesses

We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Surface by surface

Windows & doors

Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.

Mouldy bath & shower sealant

Repeat mould normally points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.

Bromley: your questions answered

Is Bromley within the area you cover?

Yes. Bromley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Bishops Stortford station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

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

Yes. First we check whether the leak is the sealant at all, then strip and reseal the joints.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

What if the leak is not the sealant?

You will hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.

How long does the work take?

The number of joints and layers decides it. We will tell you before any work starts.

Will the old sealant be removed?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Can I add another job to the visit?

Of course. Doing several areas at once is normally more efficient.

Keeping the joints in good condition

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

  • Always have old sealant cut out, not covered
  • Never fill a movement joint with mortar or grout
  • Find out why the sealant failed first
  • Have loose fittings fixed before resealing

Watch the joint over the first few weeks, particularly where the original failure was caused by movement. If anything changes, just phone 0345 464 0079 or email us.

A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Remedial sealant in Bromley: local notes

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

In and around Bromley, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint. Letting a property close to Bishops Stortford station? Then a joint that keeps failing is best fixed properly while the property is empty.
