How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. For a village or hamlet like Newgate Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.

Remedial sealant in Newgate Street
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and remedial work carries our one-year guarantee. Typical jobs include caulk or the wrong sealant used in a wet area and wide, uneven beads that look worse than the old ones, across expansion joints, mouldy bath & shower sealant and botched or over-sealed joints.
In a village or hamlet like Newgate Street, 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.
You get a 12-month guarantee, the same in Newgate Street as everywhere else we work.

What the job involves on each surface
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, then reseal neatly.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.
Remedial sealant around Newgate Street
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Rented homes near Cuffley station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Church of St Mary Ponsbourne, older homes can move a little, which is hard on rigid grout and tired sealant.

Newgate Street: your questions answered
Is Newgate Street within the area you cover?
Yes, Newgate Street is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Cuffley station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
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.
Landlords, agents and businesses in Newgate Street
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- A bath, tray or worktop that moves until it’s properly fixed
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
Do you need remedial sealant in Newgate Street?
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
Most people get in touch after spotting something like this:
- Thick, messy sealant smeared over tiles
- Over-sealed joints coming away
- Worktop sealant that has shrunk and split
- Decorators’ caulk around a bath or shower
Schools such as Ponsbourne St Mary's Church of England Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Leave it or put it right?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. Older cottages and farmhouses around Newgate Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Don’t wait for a small gap to become a leak
- Run the fan after every shower
- Don’t point over movement joints
- Have loose fittings fixed before resealing
Give the new sealant its full cure time: generally around 24 hours, or as long as we advise.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
