How we handle remedial sealant in Wallington
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. Typical jobs include leaks that keep coming back after resealing and dark patches showing through the sealant, on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints.
In a village or hamlet like Wallington, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Whatever the size of the job, it’s backed by our one-year guarantee.

Bathrooms and kitchens in Wallington
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.
Rented homes near Ashwell & Morden station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Wallington questions
I let a flat near Ashwell & Morden station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Wallington?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What does remedial sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Do you offer different sealant colours?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before work begins.
Can failed expansion joints be resealed?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What happens if it’s left?
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out, and the joint treated and dried before resealing. Where a wall is exposed, as many are in small places like Wallington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

How it works
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In a small place like Wallington, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Looking after it afterwards
Looking after new joints is easy:
- Clean sealant with mild products only
- Deal with small splits early
- Get the cause of a repeat leak found before resealing
- Don’t point over movement joints
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
When it is not the sealant
Before booking, it’s worth knowing the limits:
- A bath, tray or worktop that moves until it’s properly fixed
- A leaking trap, valve or supply pipe
- Failed tanking or loose tiles behind the sealant
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Botched or over-sealed joints
- Failed movement joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
Do you need remedial sealant in Wallington?
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
The problems people generally mention when they call are:
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
- Floor or wall movement joints that have failed
- Wide, uneven beads that look worse than the old ones
For an older house near a landmark such as Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before you book
- Who does the work, and how experienced they are

- How the surfaces are prepared before sealing
