How we quote for remedial sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- How easy the joints are to reach
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Any previous sealing or DIY work
- Where the property is
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
About our remedial sealant in Wineham
Remedial jobs in Wineham usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We work on failed movement joints, expansion joints and botched or over-sealed joints, and common reasons people get in touch are floor or wall movement joints that have failed and over-sealed joints coming away.
Somewhere as small as Wineham, 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.
Every job is covered by our 12-month guarantee, wherever you are in West Sussex.

Your questions about remedial sealant in Wineham
Is Wineham in your area for remedial sealant?
Yes. We work across London and the South East, and Wineham is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Is remedial sealant in Wineham guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.
Where do you work from?
We work from Crawley. We cover Wineham and the rest of West Sussex.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Older mastics that may need an asbestos check before removal
- A cracked shower tray or bath (that needs repair or replacing)
- A leaking trap, valve or supply pipe
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
Wineham homes and their sealant
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.
Around Wineham, as everywhere, remedial sealant is only as good as the preparation behind it. Homes close to The Parish Church of St Peter include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many layers have to come out. Somewhere as small as Wineham, 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.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Tell us about any water getting in

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach 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. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why deal with it now?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In a small place like Wineham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Different surfaces, different methods
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
