How we handle remedial sealant in Newmarket
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. Typical jobs include smears and lumps from a botched reseal and a second bead peeling off the first, on leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant.
In and around a place like Newmarket, 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 our work is covered by our 12-month guarantee.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Deal with small splits early
- Do not add new sealant on top of old
- Don’t point over movement joints
- Keep bleach and abrasives off the bead
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, drop us a line at info@mrmastic.co.uk.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Questions from Newmarket
Is Newmarket in your area for remedial sealant?
Yes, Newmarket is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is Newmarket within the area you cover?
Yes. Newmarket is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Just mention lanes, gates or anything else about the route when you book.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you remove sealant that is been put over old sealant?
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.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What we are called out for in Newmarket
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
The most common problems we see are:
- Over-sealed joints coming away
- Mould trapped under a layer of silicone
- Movement joints that have split or pulled away
- Products that weren’t meant for the joint
For jobs in and around Newmarket, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- How long the guarantee is
- Whether the sealant suits the joint
- When the joint can take water or movement
- Which colour the sealant will be

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What the job involves on each surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, and we will tell you if we find it.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Remedial sealant around Newmarket
Newmarket is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Island jobs need planning around ferries and the weather, so give us as much notice as you can.
