Four Marks Remedial Sealant
Problem with your failed sealant joints in Four Marks? We remove the old material, prepare the joints and seal them properly.
- Gaps opening along the back of the worktop
- Repeat leaks from the same joint
- Movement joints that have split or pulled away
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
How we handle remedial sealant in Four Marks
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. We work on failed movement joints, botched or over-sealed joints and expansion joints, and the jobs we see most are sealant peeling off a dusty or damp surface and over-sealed joints coming away.
In and around Four Marks, older properties sit alongside newer ones. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
All of our work is guaranteed for twelve months, in Four Marks and everywhere else we cover.

Different surfaces, different methods
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed colour-matched to the worktop.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. Both are checked before any new sealant goes on.
Landlord and commercial work in Four Marks
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Deal with small splits early
- Report a tray that rocks or a worktop that lifts
- Get the cause of a repeat leak found before resealing
- Clean sealant with mild products only
Keep the room ventilated: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a smaller place like Four Marks, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- 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
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Advice
Bathrooms and kitchens in Four Marks
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Alton station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Church of the Good Shepherd, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Four Marks Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.
