Remedial sealant in Coldwaltham
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. Typical jobs include caulk or the wrong sealant used in a wet area and gaps opening along the back of the worktop, across shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant.
Homes around Coldwaltham 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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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. Everything old must be removed first.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Cracks in the fitting rather than the joint
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints

How we quote for remedial sealant
You will get a clear quote before we start. It’s based on:
- Whether old sealant or filler has to be cut out
- Access and height
- How many rooms, windows or areas are involved
- How much there is to do
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Where the property is
- What’s wrong with the joints now
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Where a wall is exposed, as many are in small places like Coldwaltham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Signs you need remedial sealant in Coldwaltham
Sealant needs a clean, dry surface with no grease on it. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
Any of these means the joints need attention:
- Decorators’ caulk around a bath or shower
- Thick, messy sealant smeared over tiles
- A second bead peeling off the first
- Black mould underneath the bead
Rented homes near Pulborough station change hands often, and a joint that keeps failing is best fixed properly while the property is empty.

Common questions in Coldwaltham
Do you work for landlords with property near Pulborough station?
Yes. We work for landlords and agents as well as householders. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Do you cover Coldwaltham for remedial sealant?
Yes. We work across London and the South East, and Coldwaltham is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
What does remedial sealant cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Remedial sealant in Coldwaltham: local notes
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you look after a building such as St James' CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near The Parish Church of St Giles, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
