How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Donnington needs a little journey planning: 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.
- 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.
- 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.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property

Remedial sealant for homes and businesses in Donnington
A joint that keeps failing normally has a reason. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. If you have smears and lumps from a botched reseal and over-sealed joints coming away, we can put it right, on leaking tray & enclosure joints, failed movement joints and shrunken worktop sealant alike.
Around Donnington, it’s houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What else we do in Donnington
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Bathrooms and kitchens in Donnington
Donnington is within about 3 miles of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, which leaves limescale 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 Parish Church of St George, walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Chichester station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask why a joint failed before redoing it
- Never fill a movement joint with mortar or grout
- Have loose fittings fixed before resealing
- Don’t add new sealant on top of old
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
When to call us in Donnington
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
It’s worth asking for a quote if you see:
- Sealant peeling off a dusty or damp surface
- Movement joints that have split or pulled away
- Worktop sealant that has shrunk and split
- Over-sealed joints coming away
If you look after a building such as Chichester High School For Girls, 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 to look for in a quote
- Whether they’re fully insured
- How much experience the applicator has
- Is the old sealant removed completely?
- Whether the sealant suits the joint
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant can’t fix:
- Plumbing leaks behind walls or under trays
- A cracked shower tray or bath (that needs repair or replacing)
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
