Felden Remedial Sealant
Remedial sealant across Felden and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Torn expansion joints
- A second bead peeling off the first
- A shower that leaks however often it’s resealed
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Remedial sealant for homes and businesses in Felden
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you call 0345 464 0079 or drop us an email, and say how long ago it was last done. Typical jobs include caulk or the wrong sealant used in a wet area and kitchen joints letting water behind the worktop, across botched or over-sealed joints, leaking tray & enclosure joints and shrunken worktop sealant.
Homes around Felden range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Movement from fittings that are not supported
- Water damage behind tiles that needs a tiler
- A leaking trap, valve or supply pipe
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Expansion joints
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t point over movement joints
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
- Use a soft cloth, not a scourer, on silicone
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
What affects the quote in Felden
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- When we can work, for business premises
- How many rooms, windows or areas are involved
- The size of the job
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- If someone has resealed it before
- The type of property
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. 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 easy to sort out between tenants. We can quote for more than one property at once.
Remedial sealant in Felden: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. Felden is part of Hemel Hempstead, one of the post-war new towns. With many homes dating from the post-war decades, plenty of bathrooms have been resealed or refitted more than once. Sealant laid over old sealant never bonds properly, so it all has to come out.
Letting a property close to Apsley station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Homes close to Church of St Mary include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Signs you need remedial sealant in Felden
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
These are the problems we are asked about most:
- Floor or wall movement joints that have failed
- Dark patches showing through the sealant
- Gaps opening along the back of the worktop
- Sealant peeling off a dusty or damp surface
Managing a site like Nash Mills Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Your questions about remedial sealant in Felden
Do you cover smaller places like Felden?
Yes. Felden is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Apsley station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Can you fix a reseal that hasn’t worked?
Yes. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Felden.
What if resealing will not fix my leak?
Then we explain what we’ve found. A plumber or fitter may be needed.

How the visit works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work usually takes a few hours for a typical bath or shower, longer where several layers have been applied. A visit to Felden is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
