Why it’s worth doing now in Newgate Street
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead won’t last. Older cottages and farmhouses around Newgate Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes around two hours for one bath or shower, longer for a whole bathroom. Somewhere as small as Newgate Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, each joint is checked for movement and signs of water.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, usually around 24 hours.
How to prepare
- Move anything stored near the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area

Advice
Signs you need bathroom resealing in Newgate Street
Sealant laid on a damp, dusty or greasy joint never bonds properly. Traces of soap, bath oil and old sealant stop it gripping, so a rushed job can start to lift early.
Look out for any of the following:
- Gaps between the worktop and the wall
- Lumpy, uneven sealant from a DIY attempt
- Mouldy sealant that has gone black
- Leaking joints on a shower screen
Managing a site like Ponsbourne St Mary's Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What we can’t put right
It helps to know what we cannot do:
- Damage behind the tiles that needs a tiler
- Water coming from the plumbing rather than the joint
- A tray that rocks until it’s re-bedded
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you are 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.

What bathroom resealing looks like in Newgate Street
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.
If you let a flat or house near Cuffley station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. Homes close to Church of St Mary Ponsbourne include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Newgate Street questions
Do you work for landlords with property near Cuffley station?
Yes. We work for letting agents and landlords as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Newgate Street for bathroom resealing?
Yes. We work across London and the South East, and Newgate Street is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can new silicone go straight over the old?
No, and it’s one of the main reasons reseals fail. The old joint is stripped, cleaned and resealed from scratch.
Can you reseal around my kitchen sink and worktop?
Yes. We reseal worktop upstands, sinks and splashbacks, with a sealant suited to kitchens, colour-matched where it shows.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
How long does the new silicone need before I use the shower?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Keep water off it for around 24 hours, or as long as we advise for that product.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Are you insured?
Yes. Full insurance covers our work.
