How we handle remedial sealant in Temple Dinsley
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out before the joint can be done properly. If you’re dealing with movement joints that have split or pulled away and mould trapped under a layer of silicone, we can put it right.
For a small place like Temple Dinsley, 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.
Big or small, you get the same one-year guarantee.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Use a soft cloth, not a scourer, on silicone
- Do not add new sealant on top of old
- Find out why the sealant failed first
- Look for stains below bathrooms now and then
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
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.
Remedial sealant around Temple Dinsley
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as Preston Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Church of St Martin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Temple Dinsley questions
Can you do remedial sealant in Temple Dinsley?
Yes. We work across London and the South East, and Temple Dinsley is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Can you help a landlord with a rental near Stevenage station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can you quote for more than one area?
Yes, we can. More than one area can be quoted together.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Where do you work from?
Mr Mastic is based in Crawley. We cover Temple Dinsley and the rest of Hertfordshire, along with the rest of our area.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a small place like Temple Dinsley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, 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.
What we do, step by step
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. Somewhere as small as Temple Dinsley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

Common problems we fix in Temple Dinsley
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Floor or wall movement joints that have failed
- Black mould underneath the bead
Rented homes near Stevenage station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

- Are they insured?
