What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- How much there is to do
- Which sealant suits the joint
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- How we’d reach the joints
- The address or postcode of the job
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
For a quote, call 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
Remedial sealant in Whitehall
A joint that keeps letting you down needs more than another bead. It helps to have photos when you ring 0345 464 0079 or drop us an email, and say how long ago it was last done. Typical jobs include mould trapped under a layer of silicone and wide, uneven beads that look worse than the old ones, across failed movement joints, botched or over-sealed joints and mouldy bath & shower sealant.
Somewhere as small as Whitehall, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All our work is covered by a one-year guarantee, wherever you are in West Sussex.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Aftercare tips
After the cure time, these simple habits help:
- Air the bathroom so the sealant can dry
- Ask why a joint failed before redoing it
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
Common questions in Whitehall
Will you come out to Whitehall?
Yes. Whitehall is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do remedial sealant in Whitehall?
Yes. Our work covers London and the South East, and Whitehall is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.

Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
What remedial sealant looks like in Whitehall
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near The Church of St Mary the Virgin, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Letting a property close to Billingshurst station? Then a joint that keeps failing is best fixed properly while the property is empty.

Landmarks near Whitehall
The nearest railway station is Billingshurst station, roughly 3.8 miles north-west. Green spaces nearby include Knepp Wildland.
Do you need remedial sealant in Whitehall?
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Any of these means the joints need attention:
- Gaps opening along the back of the worktop
- Sealant applied over old sealant that has lifted
- Mould trapped under a layer of silicone
- Decorators’ caulk around a bath or shower
If you look after a building such as Shipley CofE Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
What your quote should include
- The length of the guarantee
- Whether they’re fully insured
- How long to leave it before use
- What product goes in the joint
What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- A tray or bath that’s cracked
- A tray or worktop that needs refixing first
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Where we work in Whitehall
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
- Botched or over-sealed joints
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Whitehall, 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- Tell us about any water getting in
- Mention any parking rules near the property
- Mention if the joints have been sealed before
