Why act early in Cranmore
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Older cottages and farmhouses around Cranmore can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Remedial sealant in Cranmore
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. If you have caulk or the wrong sealant used in a wet area and a shower that leaks however often it’s resealed, we can help, whatever the surface.
In a village or hamlet like Cranmore, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Your job is guaranteed for a year, as with all our work.

Common problems we fix in Cranmore
Joints that move need sealant that can stretch. 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:
- Thick, messy sealant smeared over tiles
- Dark patches showing through the sealant
- A shower that leaks however often it’s resealed
- Decorators’ caulk around a bath or shower
For landlords with property near Lymington Pier station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Remedial sealant in Cranmore: local notes
Cranmore is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Managing a site like Shalfleet Church of England Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Cranmore: your questions answered
Can you do remedial sealant in Cranmore?
Yes, Cranmore is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
I let a flat near Lymington Pier station. Can you help?
Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
What if the leak isn’t the sealant?
You will hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, and we will not reseal for the sake of it.
Someone sealed over the old bead. Can you fix it?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Different surfaces, different methods
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and point out any existing damage.
What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Cranmore needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
