How the job changes by surface

Over-sealed & botched joints

A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.

How we handle remedial sealant in Trowley Bottom

Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We work on shrunken worktop sealant, leaking tray & enclosure joints and failed movement joints, and common reasons people get in touch are repeat leaks from the same joint and dark patches showing through the sealant.

Around Trowley Bottom, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Questions from Trowley Bottom

Is Trowley Bottom within the area you cover?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do remedial sealant in Trowley Bottom?

Yes. We work across London and the South East, and Trowley Bottom is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do you do commercial work?

Yes, regularly. We can plan bigger jobs in stages.

Do you work for landlords and businesses?

Yes. Domestic, commercial and hotel work are all part of what we do.

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Is remedial work guaranteed?

Yes. Remedial work carries the same 12-month guarantee as all our work.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.

What affects the quote in Trowley Bottom

You will get a clear quote before work begins. It takes into account:

  • How many rooms, windows or areas are involved
  • The size of the job
  • The product the joint needs
  • Any mould that needs treating

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Asking for a quote

What to tell us when you ask for a quote:

  • Access, such as stairs, a lift or height
  • What’s wrong with the joints now
  • The address or postcode of the job
  • If someone has resealed it before

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

Leave it or put it right?

A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you will hear it from us. Around Trowley Bottom, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What you get with us

  • A sealant colour to suit the surroundings
  • Neat joints and a tidy finish
  • Every job guaranteed for a year
  • Anti-fungal silicone where joints get wet

When something else is needed

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • A tray or worktop that needs refixing first
  • A cracked shower tray or bath (that needs repair or replacing)
  • Plumbing leaks behind walls or under trays

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

What we seal

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

What we do, step by step

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours, depending on how many layers have to come out for a typical job. For a village or hamlet like Trowley Bottom, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. We strip the joint completely, removing any layers below.
  3. Next, any mould is treated and the joint dried.
  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.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any parking rules near the property
  • Mention if the joints have been sealed before

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Trowley Bottom homes and their sealant

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

When to call us in Trowley Bottom

Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.

The most common problems we see are:

  • Sealant applied over old sealant that has lifted
  • A shower that leaks however often it’s resealed
  • Mould trapped under a layer of silicone
  • Torn expansion joints

Homes close to Church of St Leonard include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
