About our remedial sealant in Woollensbrook
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. Only then can new sealant bond. If you are dealing with repeat leaks from the same joint and thick, messy sealant smeared over tiles, we can help, whatever the surface.
Homes around Woollensbrook are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Woollensbrook
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
The problems people generally mention when they call include:
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
- Torn expansion joints
- Sealant peeling off a dusty or damp surface
For an older house near a landmark such as Church of St Catherine & St Paul, walls and floors in older homes can move, and sealant and grout show it first.

- Who turns up on the day
- How the surfaces are prepared before sealing

Honest limits
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:
- Sealant in an older building that needs testing for asbestos first
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Shrunken worktop sealant
- Botched or over-sealed joints
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
Remedial sealant in Woollensbrook: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Rented homes near Rye House station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. If you look after a building such as Westfield Community Primary School, 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.

Leave it or put it right?
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Woollensbrook, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Surface by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What affects the quote in Woollensbrook
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- The old material and how stubborn it is
- The type of sealant required
- The number of rooms or windows
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- How many joints, rooms or windows are involved
- How we’d reach the joints
- Where the property is
Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Woollensbrook, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
