Gundleton Remedial Sealant
Our applicators work in Gundleton on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Decorators’ caulk around a bath or shower
- Dark patches showing through the sealant
- Over-sealed joints coming away
How the visit works
We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, and we tell you how long to leave it before we go. Somewhere as small as Gundleton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

Advice
How we handle remedial sealant in Gundleton
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 email us, along with when it was last resealed. We work on mouldy bath & shower sealant, failed movement joints and expansion joints, and the jobs we see most are thick, messy sealant smeared over tiles and sealant applied over old sealant that has lifted.
Somewhere as small as Gundleton, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Big or small, you get the same 12-month guarantee.

Remedial sealant around Gundleton
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as Church of All Saints, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Questions from Gundleton
Do you cover Gundleton for remedial sealant?
Yes, Gundleton is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Do you cover smaller places like Gundleton?
Yes. Gundleton 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.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
What if the leak is not the sealant?
That’s why we look for the cause first. If we find the leak is elsewhere, we tell you before going further.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Looking after it afterwards
After the cure time, these simple habits help:
- Use a soft cloth, not a scourer, on silicone
- Check trays and worktops do not move
- Act on a lifting corner right away
- Ask why a joint failed before redoing it
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
What affects the quote in Gundleton
Jobs vary more than people expect. What affects the quote:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The amount of work
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Call for a quick quote and we will go through it with you.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Access, such as stairs, a lift or height
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.

Leave it or put it right?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Around Gundleton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- A tray or bath that is cracked
- Water damage behind tiles that needs a tiler
- Sealant in an older building that needs testing for asbestos first
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

When to call us in Gundleton
Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
People generally contact us after spotting one of these:
- Torn expansion joints
- Sealant applied over old sealant that has lifted
- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
Managing a site like Perins School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
