How we handle remedial sealant in Great Dunmow
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are sealant applied over old sealant that has lifted and sealant peeling off a dusty or damp surface.
Even in a smaller place like Great Dunmow, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What affects the quote in Great Dunmow
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- How many rooms, windows or areas are involved
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- A few pictures by email, if you can
- How we’d reach the joints
- Whether it’s a home or a business
- Roughly how big the job is
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll come back to you with a quote.
Different surfaces, different methods
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is normally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Around Great Dunmow, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.

Aftercare tips
To keep the joints looking good and working properly:
- Have loose fittings fixed before resealing
- Find out why the sealant failed first
- Act on a lifting corner right away
- Keep an eye on the ceiling below the bathroom
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, phone 0345 464 0079 or send us an email.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
How it works
The work is kept neat and contained to the joints we’re treating. The job usually takes a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Great Dunmow, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area

Great Dunmow homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings. Great Dunmow 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.
For an older house near a landmark such as Parish Church of St Mary the Virgin, older homes can move a little, which is hard on rigid grout and tired sealant. If you look after a building such as Dunmow St Mary's Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Great Dunmow questions
Do you work in hotels near Great Dunmow?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
I let a flat near Stansted Airport station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. Most jobs take a few hours.
Do you cover Great Dunmow?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
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 if resealing will not fix my leak?
That’s why we look for the cause first. If the fault is elsewhere, you’ll know before any work is done.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
When to call us in Great Dunmow
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.
It’s worth asking for a quote if you see:
- A second bead peeling off the first
- Decorators’ caulk around a bath or shower
- Floor or wall movement joints that have failed
- Sealant peeling off a dusty or damp surface
If you let a flat or house near Stansted Airport station, a joint that keeps failing is best fixed properly while the property is empty.
What your quote should include
- How much experience the applicator has
- How the surfaces are prepared before sealing
- How long to leave it before use
- How the colour is chosen
