How we handle remedial sealant in Downley
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. Common call-outs are for leaks that keep coming back after resealing and decorators’ caulk around a bath or shower, on shrunken worktop sealant, failed movement joints and leaking tray & enclosure joints.
Somewhere as small as Downley, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Downley: your questions answered
Will you come out to Downley?
Yes, Downley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Downley in your area for remedial sealant?
Yes, Downley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or email us.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Landlords, agents and businesses in Downley
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Common problems we fix in Downley
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that is too stiff or too thin.
Any of these means the joints need attention:
- Decorators’ caulk around a bath or shower
- A shower that leaks however often it’s resealed
- Worktop sealant that has shrunk and split
- A second bead peeling off the first
Homes close to St. James the Great include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
Questions to ask before booking
- Whether they seal over old material or remove it
- How hidden problems are handled
- Whether VAT is included
- Whether you can choose the colour
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Remedial sealant in Downley: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a building such as The Downley School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to High Wycombe station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

When it isn’t the sealant
We won’t take on work that will not last, so these are the limits:
- Movement from fittings that are not supported
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
What the job involves on each surface
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom before resealing.
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We’ll tell you what we find.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. In a small place like Downley, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
