How we handle remedial sealant in Newpound Common
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We are often asked to deal with floor or wall movement joints that have failed and leaks that keep coming back after resealing, across botched or over-sealed joints, leaking tray & enclosure joints and mouldy bath & shower sealant.
For a small place like Newpound Common, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
We stand behind the work with a one-year guarantee.

Aftercare tips
To keep the joints looking good and working properly:
- Always have old sealant cut out, not covered
- Run the fan after every shower
- Use a soft cloth, not a scourer, on silicone
- Act on a lifting corner straight away
Keep the room ventilated: run the fan during and after showers, or open a window.
Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
Why act early in Newpound Common
Another bead over the top will not fix a failed joint. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Older cottages and farmhouses around Newpound Common 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 size of the job, 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, so you know where you stand.

How we quote for remedial sealant
We do not publish a price list, because jobs vary so much. What we look at:
- The type of sealant required
- Mould in or behind the old joints
- How easy the joints are to reach
- The old material and how stubborn it is
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What to tell us for a quote
What to tell us when you ask for a quote:
- Whether it has been sealed before
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
When it isn’t the sealant
It helps to know what we can’t do:
- Plumbing leaks behind walls or under trays
- Movement from fittings that are not supported
- Cracks in the fitting rather than the joint
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
What the job involves on each surface
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, so the sealant grips the two sides only.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. Somewhere as small as Newpound Common, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- 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.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on

Advice
Towns and villages near Newpound Common
Also in Newpound Common
Bathrooms and kitchens in Newpound Common
Most of the South East has hard water, so limescale builds up 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 Wisborough Green Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. Rented homes near Billingshurst station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Homes close to The Parish Church of St Peter Ad Vincula include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What if resealing will not fix my leak?

Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
