How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed colour-matched to the worktop.
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Remedial sealant in Uckfield, done properly
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. If you’re dealing with over-sealed joints coming away and repeat leaks from the same joint, we can help, on shrunken worktop sealant, failed movement joints and expansion joints alike.
Uckfield mixes older houses with estates built more recently, so bathrooms range from long-standing suites to recent refits. Either way, the sealant and grout are generally the first things to fail.
Every job comes with our one-year guarantee.

Bathrooms and kitchens in Uckfield
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings. Uckfield has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as St Saviour, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Uckfield station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

Uckfield: your questions answered
Can you do remedial sealant in Uckfield?
Yes, Uckfield is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Can you remove old sealant without damaging the bath?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Where do you work from?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, so we find that first.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. A visit in Uckfield needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
How to get a quote
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, and we’ll take it from there.
Advice
Signs you need remedial sealant in Uckfield
One of the commonest remedial jobs is sealant on top of sealant. Silicone doesn’t bond to silicone, so the new layer peels, and damp and mould settle between them.
If you can see any of these, it’s time to have the joints looked at:
- Black mould underneath the bead
- Kitchen joints letting water behind the worktop
- Decorators’ caulk around a bath or shower
- Sealant applied over old sealant that has lifted
Schools such as St Philip's Catholic Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

What we can’t put right
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Water damage behind tiles that needs a tiler
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
