Problem with your failed sealant joints in Founthill? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.

How we handle remedial sealant in Founthill
Some sealant jobs are not a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. If you are dealing with products that weren’t meant for the joint and dark patches showing through the sealant, we can put it right, on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints alike.
For a small place like Founthill, 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.
A 12-month guarantee comes as standard.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. It will not solve:
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe
- A tray or worktop that needs refixing first
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Leaking tray & enclosure joints
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
What the job involves on each surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, and we will tell you if we find it.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. For a village or hamlet like Founthill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- 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.
How to prepare
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
- Tell us if parking is tricky

What remedial sealant looks like in Founthill
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Homes close to The Parish Church of St Mary include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Uckfield station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Newick Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Why deal with it now?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Around Founthill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Founthill questions

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you have insurance?
Yes. Full insurance covers our work.
Can you remove sealant that’s been put over old sealant?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I do 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.
My shower still leaks after a reseal. Can you sort it?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, so we find that first.

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved.
How to look after the new joints
Looking after new joints is easy:
- Run the fan after every shower
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
- Act on a lifting corner straight away
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
