Remedial sealant for homes and businesses in Bagmore
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. Common call-outs are for sealant that came away because the surface wasn’t prepared and worktop sealant that has shrunk and split, on botched or over-sealed joints, shrunken worktop sealant and mouldy bath & shower sealant.
Homes around Bagmore are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Whatever the size of the job, it’s backed by our one-year guarantee in Bagmore and across Hampshire.

Signs you need remedial sealant in Bagmore
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Keep an eye out for any of the following:
- Torn expansion joints
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
- Smears and lumps from a botched reseal
For an older house near a landmark such as Church of St. Mary, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before you book
- When the joint can take water or movement
- What the quote includes, VAT included or not
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Have loose fittings fixed before resealing
- Always have old sealant cut out, not covered
- Act on a lifting corner right away
- Clean sealant with mild products only
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Common questions in Bagmore
Can you help a landlord with a rental near Alton station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Is Bagmore in your area for remedial sealant?
Yes, Bagmore is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
How do I get a quote for remedial sealant in Bagmore?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
How long does remedial resealing take?
That depends on how many layers there are and how many joints. We’ll tell you before work begins.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before work begins.
The process
Once we’re 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. Somewhere like Bagmore 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.
- 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.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

Advice
Why act early in Bagmore
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Around Bagmore, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Tiles that have come away from the wall
- Plumbing leaks behind walls or under trays
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
