Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Common problems we fix in Hunton Bridge
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
Common reasons people contact us are:
- Kitchen joints letting water behind the worktop
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
Managing a site like St Paul's Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What affects the cost of remedial sealant
For a quick quote, just ask. What matters most is:
- Whether the work is at height
- Which sealant suits the joint
- The number and length of the joints
- How many areas need sealing
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
When you contact us, it’s useful to know:
- The type of property
- How many joints, rooms or windows are involved
- The address or postcode of the job
- If someone has resealed it before
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
When it is not the sealant
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

Remedial sealant in Hunton Bridge: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Kings Langley station? Then botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as Church of St Paul, older homes can move a little, which is hard on rigid grout and tired sealant.

Why it’s worth doing now in Hunton Bridge
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Around Hunton Bridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

- Sanitary silicone with an anti-fungal additive in wet areas

Questions from Hunton Bridge
Can you do remedial sealant in Hunton Bridge?
Yes, Hunton Bridge is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Kings Langley station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, 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.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How the job changes by surface
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
