Remedial sealant around Great Waltham
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For landlords with property near Beaulieu Park station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Chelmer Valley High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Remedial sealant for homes and businesses in Great Waltham
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you are dealing with over-sealed joints coming away and mould trapped under a layer of silicone, we can put it right.
For a small place like Great Waltham, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Questions from Great Waltham
Is Great Waltham in your area for remedial sealant?
Yes. Our work covers London and the South East, and Great Waltham is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.
Do you cover smaller places like Great Waltham?
Yes. Great Waltham 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.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Do you guarantee remedial jobs?
Yes. Remedial work carries the same 12-month guarantee as all our work.
How do I get a quote for remedial sealant in Great Waltham?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or send us an email with a short description of the job.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How it works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Great Waltham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
Why deal with it now?
Mould under a bead cannot be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. Older cottages and farmhouses around Great Waltham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

When to call us in Great Waltham
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
If you can see any of these, it’s time to have the joints looked at:
- Repeat leaks from the same joint
- Kitchen joints letting water behind the worktop
- Sealant applied over old sealant that has lifted
- Sealant that came away because the surface wasn’t prepared
For an older house near a landmark such as Church of SS Mary and Laurence, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before you book
- Who turns up on the day
- How long the guarantee is
- Whether you can choose the colour
- Whether the sealant suits the joint

- When we can work, for business premises
- Any mould that needs treating
- Access and height
- How much there is to do

What we need to know
When you contact us, these details help:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or drop us an email.
Honest limits
A few problems are outside what sealant work can do:
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
- Sealant in an older building that needs testing for asbestos first
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Where we work in Great Waltham
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
What the job involves on each surface
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
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 we reseal.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Check ceilings under showers for marks
- Always have old sealant cut out, not covered
- Do not wait for a small gap to become a leak
- Have loose fittings fixed before resealing
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
