How we handle remedial sealant in Thurnham
In Thurnham, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and expansion joints, and the jobs we see most are dark patches showing through the sealant and over-sealed joints coming away.
Homes around Thurnham are mostly 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 as standard.

Questions from Thurnham
Do you work for landlords with property near Bearsted station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is Thurnham within the area you cover?
Yes. Thurnham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you fix a reseal that hasn’t worked?
Yes. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where do you work from?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Remedial sealant around Thurnham
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Rented homes near Bearsted station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Valley Park School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to St Mary the Virgin Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Quotes for remedial sealant in Thurnham
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- How many areas need sealing
- When we can work, for business premises
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- Where the property is
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on how many layers have to come out. For a village or hamlet like Thurnham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

What we can’t put right
In fairness, there are a few things sealant won’t fix:
- Plumbing leaks behind walls or under trays
- Cracks in the fitting rather than the joint
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
Why it’s worth doing now in Thurnham
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Around Thurnham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
