Colt's Hill Remedial Sealant
We cover Colt's Hill for removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Sealant applied over old sealant that has lifted
- Beads that never stuck properly
- Torn expansion joints
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Remedial sealant for homes and businesses in Colt's Hill
A joint that keeps letting you down needs more than another bead. Send photos when you phone 0345 464 0079 or email us. Common call-outs are for sealant applied over old sealant that has lifted and sealant that came away because the surface wasn’t prepared, across botched or over-sealed joints, mouldy bath & shower sealant and shrunken worktop sealant.
In a village or hamlet like Colt's Hill, 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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Remedial sealant around Colt's Hill
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Homes close to Five Oak Green Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Paddock Wood station, botched sealant from a previous quick fix is easier to strip out between tenants.

For landlords and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. For a village or hamlet like Colt's Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or send us an email with the details and send photos if you have them.
Advice
Looking after it afterwards
So the new joints stay in good condition:
- Keep movement joints clear of mortar and paint
- Do not wait for a small gap to become a leak
- Always have old sealant cut out, not covered
- Check trays and worktops don’t move
Do not let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Common questions in Colt's Hill
Is Colt's Hill within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Paddock Wood station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. Where we’ve flagged another fault, it needs fixing for the joint to last.
Where is Mr Mastic based?
We work from Crawley. We cover Colt's Hill and the rest of Kent, along with the rest of our area.
Can you fix a reseal that hasn’t worked?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
How long does the work take?
A little longer than a standard reseal. For most joints, it’s a few hours.
What we’re called out for in Colt's Hill
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Common reasons people contact us are:
- Floor or wall movement joints that have failed
- Kitchen joints letting water behind the worktop
- Repeat leaks from the same joint
- Over-sealed joints coming away
For site and facilities teams at buildings such as Capel 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 happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Where a wall is exposed, as many are in small places like Colt's Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
