How we handle remedial sealant in Preston
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. Common call-outs are for decorators’ caulk around a bath or shower and floor or wall movement joints that have failed, across leaking tray & enclosure joints, botched or over-sealed joints and expansion joints.
For a small place like Preston, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
All our work comes with our one-year guarantee, wherever you are in Hertfordshire.

What we’re called out for in Preston
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. Then the only fix is removal and a new bead.
If you can see any of these, it’s time to have the joints looked at:
- Beads that never stuck properly
- Sealant applied over old sealant that has lifted
- Leaks that keep coming back after resealing
- Products that weren’t meant for the joint
Letting a property close to Hitchin station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Questions from Preston
Do you work for landlords with property near Hitchin station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you do remedial sealant in Preston?
Yes. We work across London and the South East, and Preston is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
What should I tell you?
Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee, and we’re fully insured.
Bathrooms and kitchens in Preston
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Preston Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to Church of St Martin include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. Somewhere as small as Preston, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

Other services in Preston
What we cannot put right
To be straight with you, there are a few things sealant won’t fix:
- Sealant in an older building that needs testing for asbestos first
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.
Joints and surfaces we work on
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints
Why it’s worth doing now in Preston
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Preston, older homes often have timber in their floors and frames, where water from a failed joint can cause rot 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.
What you get with us
- Over 20 years’ experience
- We agree the colour with you first
- Domestic, commercial and hotel work
- Sanitary silicone with an anti-fungal additive in wet areas

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Check trays and worktops do not move
- Clean sealant with mild products only
- Get the cause of a repeat leak found before resealing
- Deal with small splits early
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
