Remedial sealant in Lower Dicker, done properly
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on expansion joints, botched or over-sealed joints and failed movement joints, and common reasons people get in touch are repeat leaks from the same joint and floor or wall movement joints that have failed.
Being in a small place like Lower Dicker makes no difference to the job itself: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
Your job is guaranteed for a year, as with all our work.

Lower Dicker: your questions answered
Is Lower Dicker within the area you cover?
Yes, Lower Dicker is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Berwick (Sussex) station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
Can you strip sealant from an acrylic tray safely?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
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.
Do you have insurance?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Don’t point over movement joints
- Keep the room well ventilated
- Find out why the sealant failed first
- Keep an eye on the ceiling below the bathroom
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
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.
How the job changes by surface
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Remedial sealant around Lower Dicker
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Zoar Strict Baptist Chapel, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For landlords with property near Berwick (Sussex) station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Hellingly Community Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Why act early in Lower Dicker
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like Lower Dicker, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on how much there is to do. Somewhere as small as Lower Dicker, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
