About our remedial sealant in Charlton
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. We are often asked to deal with leaks that keep coming back after resealing and sealant applied over old sealant that has lifted, across failed movement joints, leaking tray & enclosure joints and expansion joints.
For a small place like Charlton, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
Each job carries a 12-month guarantee, large or small.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A tray or worktop that needs refixing first
- Tiles that have come away from the wall
- A leaking trap, valve or supply pipe
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Why it’s worth doing now in Charlton
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Charlton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

Do you need remedial sealant in Charlton?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
The most common problems we see are:
- Beads that never stuck properly
- Leaks that keep coming back after resealing
- Torn expansion joints
- Gaps opening along the back of the worktop
Schools such as Singleton CofE Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- Whether they’re fully insured
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
- What happens if they find a problem under the old sealant
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours, depending on how many layers have to come out. Somewhere like Charlton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions

Aftercare tips
So the new joints stay in good condition:
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- Air the bathroom so the sealant can dry
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: follow the cure time we give you.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
Charlton homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. There are hotels and other places to stay in and around Charlton. 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 The Parish Church of the Blessed Virgin Mary, older homes can move a little, which is hard on rigid grout and tired sealant.

Questions from Charlton
Is Charlton within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and guest houses in Charlton?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
My shower still leaks after a reseal. Can you sort it?
Yes. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Can you reseal a split movement joint?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Can old silicone be taken off without scratching the tiles?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that is already there.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
