About our remedial sealant in Cold Christmas
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on shrunken worktop sealant, expansion joints and mouldy bath & shower sealant, and common reasons people get in touch are worktop sealant that has shrunk and split and floor or wall movement joints that have failed.
Around Cold Christmas, 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.
You get a one-year guarantee, the same in Cold Christmas as everywhere else we work.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a small place like Cold Christmas, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What we do, step by step
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out in most cases. In a small place like Cold Christmas, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- 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.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

Advice
Signs you need remedial sealant in Cold Christmas
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
The most common problems we see are:
- Repeat leaks from the same joint
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
- Kitchen joints letting water behind the worktop
For an older house near a landmark such as Parish Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before booking
- What the quote includes, VAT included or not
- What preparation is included
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
Cold Christmas homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Managing a site like Thundridge Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Ware station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What we can’t put right
To be straight with you, some problems need a different trade:
- Tiles that have come away from the wall
- Plumbing leaks behind walls or under trays

If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
Keeping the joints in good condition
Aftercare is simple:
- Look for stains below bathrooms now and then
- Deal with small splits early
- Never fill a movement joint with mortar or grout
- Always have old sealant cut out, not covered
Keep the room ventilated: 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.
