Remedial sealant in Appspond
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. We work on mouldy bath & shower sealant, failed movement joints and leaking tray & enclosure joints, and people most often call us about sealant that came away because the surface wasn’t prepared and decorators’ caulk around a bath or shower.
For a small place like Appspond, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.

Yes, we’re fully insured.
Does remedial work come with a guarantee?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Can you fix a reseal that hasn’t worked?
Yes, normally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
What if resealing won’t fix my leak?
We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we won’t pretend it will.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
The process
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work usually takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Appspond, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.

Appspond homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Marlborough Science Academy, we reseal washrooms and kitchens in schools and businesses as well as homes.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Deal with small splits early
- Keep bleach and abrasives off the bead
- Look for stains below bathrooms now and then
- Report a tray that rocks or a worktop that lifts
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or send us an email.
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. Any of them means it’s time for remedial work.
Common problems we fix in Appspond
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
The most common problems we see are:
- Sealant peeling off a dusty or damp surface
- Sealant applied over old sealant that has lifted
- Movement joints that have split or pulled away
- Gaps opening along the back of the worktop
Rented homes near St Albans Abbey station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, 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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What the job involves on each surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
