When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Older mastics that may need an asbestos check before removal
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Expansion joints
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Failed movement joints
How we handle remedial sealant in Graveley
A joint that keeps failing normally has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. If you have products that weren’t meant for the joint and a shower that leaks however often it’s resealed, we can help, whatever the surface.
In a village or hamlet like Graveley, 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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Where a wall is exposed, as many are in small places like Graveley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why Graveley customers choose us
- Neat joints and a tidy finish
- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas
- We never seal over old sealant
See our cost guide and our reviews.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. Somewhere as small as Graveley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in

Advice
Common questions in Graveley
Do you cover smaller places like Graveley?
Yes, Graveley is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do remedial sealant in Graveley?
Yes, Graveley is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Do you fix expansion and movement joints?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, then the joint is sealed properly.
What if resealing won’t fix my leak?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we won’t reseal for the sake of it.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
How long does the work take?
Allow a few hours, depending on how many layers have to come out. You’ll know the timing when we quote.

Bathrooms and kitchens in Graveley
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.
For site and facilities teams at buildings such as Graveley Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Stevenage station, a joint that keeps failing is best fixed properly while the property is empty.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Get the cause of a repeat leak found before resealing
- Air the bathroom so the sealant can dry
- Don’t add new sealant on top of old
- Keep an eye on the ceiling below the bathroom
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Early action keeps it to a sealant job.
Common problems we fix in Graveley
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
The most common problems we see are:
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Over-sealed joints coming away
- Decorators’ caulk around a bath or shower
If you live in an older home near Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
