About our remedial sealant in Downton
In Downton, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. We strip each one back and start from scratch. If you’re dealing with dark patches showing through the sealant and movement joints that have split or pulled away, we can help, whatever the surface.
In a village or hamlet like Downton, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Each job carries a 12-month guarantee, large or small.

Quotes for remedial sealant in Downton
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- Which sealant suits the joint
- Access and height
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Other services in Downton
Why act early in Downton
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Downton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why choose Mr Mastic in Downton
- White, clear, grey or coloured to suit, where the product allows
- An ARBOMaster approved applicator
- You choose the colour before work begins
- Quality sealants from Arbo and Everbuild
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Cracks in the fitting rather than the joint
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
What we seal
- Expansion joints
- Leaking tray & enclosure joints
- Failed movement joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
What the job involves on each surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. We rake that out where it can be removed and seal with a flexible product.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, which we’ll point out.
Downton homes and their sealant
Downton is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. 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.
Rented homes near New Milton station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as Church of All Saints, walls and floors in older homes can move, and sealant and grout show it first.

Downton questions
I let a flat near New Milton station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Will you come out to Downton?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long will it take to strip and reseal the joint?
A little longer than a standard reseal. Most jobs take a few hours.
How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Downton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

Advice
When to call us in Downton
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the top layer lifts and water and mould collect between the two.
The problems people normally mention when they call include:
- Sealant applied over old sealant that has lifted
- Movement joints that have split or pulled away
- Mould trapped under a layer of silicone
- Kitchen joints letting water behind the worktop
Schools such as Hordle CofE (VA) Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- When the joint can take water or movement
- How the joint is cleaned and prepared
- What product goes in the joint
- What happens if the job turns out different
