When to call us in The Heath
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
People generally contact us when they notice one of these:
- Over-sealed joints coming away
- Beads that never stuck properly
- Dark patches showing through the sealant
- A shower that leaks however often it’s resealed
Managing a site like Breachwood Green Junior Mixed and Infant School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before you book
- What guarantee comes with the work
- Whether you can choose the colour
- When the joint can take water or movement
- Whether they seal over old material or remove it
Remedial sealant in The Heath, done properly
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Typical jobs include black mould underneath the bead and sealant that came away because the surface wasn’t prepared, on leaking tray & enclosure joints, expansion joints and mouldy bath & shower sealant.
For a small place like The Heath, 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.
Our work is backed for twelve months.

Quotes for remedial sealant in The Heath
We quote each job individually. This is what makes a difference:
- The size of the job
- Mould in or behind the old joints
- How many areas need sealing
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Helping us quote
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- Any previous sealing or DIY work
- What’s wrong with the joints now
- The address or postcode of the job
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work and send you a clear quote.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. In a small place like The Heath, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- 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.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in

Advice
The Heath homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Homes close to Church of St Mary include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Luton Airport Parkway station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Questions from The Heath
Can you do remedial sealant in The Heath?
Yes. Our work covers London and the South East, and The Heath is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Is The Heath within the area you cover?
Yes, The Heath 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.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
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 if resealing will not fix my leak?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we won’t reseal for the sake of it.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.

Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Older cottages and farmhouses around The Heath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
What you get with us
- We leave the area clean and tidy
- Anti-fungal sanitary silicone in wet areas
- ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
See our cost guide and our reviews.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we can’t put right
We won’t take on work that won’t last, so these are the limits:
- Plumbing leaks behind walls or under trays
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
