Remedial sealant for homes and businesses in Southerness
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you have worktop sealant that has shrunk and split and movement joints that have split or pulled away, we can put it right, whatever the surface.
In and around a place like Southerness, homes range from older stone-built properties to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
All of our work is guaranteed for twelve months, in Southerness and everywhere else we cover.

DIY sealant or a professional job?
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check ceilings under showers for marks
- Run the fan after every shower
- Have loose fittings fixed before resealing
- Don’t point over movement joints
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
What affects the cost of remedial sealant
The quote reflects the job in front of us. We take into account:
- The number and length of the joints
- The product the joint needs
- How many areas need sealing
- When we can work, for business premises
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- The type of property
- Where the job is, and your postcode
- Any access issues, like height or stairs
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work.
Remedial sealant around Southerness
Southerness is close to 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. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
For jobs in and around Southerness, choosing the right material for each joint is as important as a tidy finish.

Signs you need remedial sealant in Southerness
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
Keep an eye out for these signs:
- Sealant that came away because the surface wasn’t prepared
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
- A shower that leaks however often it’s resealed
Around Southerness, as everywhere, remedial sealant is only as good as the preparation behind it.

Southerness: your questions answered
Is Southerness within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is remedial sealant in Southerness guaranteed?
All our work, in Southerness and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you fix expansion and movement joints?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Someone sealed over the old bead. Can you fix it?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on how much there is to do. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Advice
How the job changes by surface
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
