How we handle remedial sealant in Sevenscore
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. We work on expansion joints, failed movement joints and leaking tray & enclosure joints, and people most often call us about torn expansion joints and sealant peeling off a dusty or damp surface.
For a small place like Sevenscore, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
We stand behind the work with a one-year guarantee.

Common problems we fix in Sevenscore
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Look out for these signs:
- Mould trapped under a layer of silicone
- Torn expansion joints
- Repeat leaks from the same joint
- Sealant peeling off a dusty or damp surface
If you live in an older home near St Mary, walls and floors in older homes can move, and sealant and grout show it first.

How we quote for remedial sealant
We quote each job individually. This is what makes a difference:
- When we can work, for business premises
- The number of rooms or windows
- The old material and how stubborn it is
- The size of the job
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- How many joints, rooms or windows are involved

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours, depending on how many layers have to come out, depending on the size of the job. Somewhere like Sevenscore needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises

Leave it or put it right?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours for a typical bath or shower, longer where several layers have been applied. It’s far less disruption than resealing the same joint again and again. Older cottages and farmhouses around Sevenscore can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Have loose fittings fixed before resealing
- Clean sealant with mild products only
- Never fill a movement joint with mortar or grout
- Run the fan after every shower
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Different surfaces, different methods
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
Remedial sealant around Sevenscore
Sevenscore is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Thanet Parkway station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
