Your questions about remedial sealant in Charlton
Do you work in hotels near Charlton?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Will you come out to Charlton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can you take off two layers of silicone?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
How we handle remedial sealant in Charlton
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. If you are dealing with over-sealed joints coming away and products that weren’t meant for the joint, we can put it right, on leaking tray & enclosure joints, mouldy bath & shower sealant and botched or over-sealed joints alike.
Around Charlton, you will mostly find houses and bungalows, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Big or small, you get the same one-year guarantee in Charlton and across Oxfordshire.

Common problems we fix in Charlton
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
These are the problems we’re asked about most:
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
- Products that weren’t meant for the joint
- Wide, uneven beads that look worse than the old ones
If you look after a building such as Charlton Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
Questions to ask before you book
- Is VAT in the price?
- What happens if the job turns out different
- Who turns up on the day
- Whether you can choose the colour
When something else is needed
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Movement from fittings that are not supported
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check ceilings under showers for marks
- Have loose fittings fixed before resealing
- Keep the room well ventilated
- Use a soft cloth, not a scourer, on silicone
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Do not keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.

How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In a smaller place like Charlton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Move anything stored near the joints

Advice
Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a smaller place like Charlton, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
