What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many layers have to come out from start to finish. Somewhere as small as Shelvin, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Advice
About our remedial sealant in Shelvin
The wrong product in the wrong joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. If you are dealing with smears and lumps from a botched reseal and caulk or the wrong sealant used in a wet area, we can help, on mouldy bath & shower sealant, leaking tray & enclosure joints and shrunken worktop sealant alike.
Homes around Shelvin are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Shelvin
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. Where a wall is exposed, as many are in small places like Shelvin, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Common questions in Shelvin
Can you help a landlord with a rental near Shepherds Well station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Shelvin?
Yes, Shelvin 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.
What does remedial sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Can you do several jobs on one visit?
Of course. Doing several areas at once is normally more efficient.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Shelvin homes and their sealant
Shelvin has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
In the older streets around Church of St Martin, walls and floors in older homes can move, and sealant and grout show it first. If you let a flat or house near Shepherds Well station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. We rake that out where it can be removed and seal with a flexible product.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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.
