Remedial sealant in St John's, done properly
Some sealant jobs are not a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. Common call-outs are for movement joints that have split or pulled away and kitchen joints letting water behind the worktop, on expansion joints, failed movement joints and leaking tray & enclosure joints.
In and around St John's, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Each job carries a 12-month guarantee, large or small.

What affects the quote in St John's
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site
- The size of the job
- The old material and how stubborn it is
- Mould in or behind the old joints
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- A few pictures by email, if you can
- Where the property is
- The problem you’ve noticed
If you are in St John's and need remedial sealant, call 0345 464 0079 or email us. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.
What we’re called out for in St John's
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
If you can see any of these, it’s time to have the joints looked at:
- Kitchen joints letting water behind the worktop
- Black mould underneath the bead
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
If you look after a building such as The Winston Churchill School A Specialist Sports College, 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.
What your quote should include
- How long to leave it before use
- Are they insured?
- What guarantee comes with the work
- Which sealant they’ll use, and why
Remedial sealant in St John's: local notes
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.
For landlords with property near Woking station, 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 St John's Church, walls and floors in older homes can move, and sealant and grout show it first.
St John's is about 1 mile west of Woking, in Surrey. Whether you are in the middle of St John's or further out, we cover remedial sealant for every kind of property. St John's is one of 395 places in Surrey where we work for remedial sealant. We also work in Reading, around 19 miles away.

Aftercare tips
A little care helps the new joints last. We recommend:
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
- Check trays and worktops don’t move
- Never seal over old silicone
Give the new sealant its full cure time: follow the cure time we give you.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
When something else is needed
It helps to know what we cannot do too:
- Older mastics that may need an asbestos check before removal
- Plumbing leaks behind walls or under trays
- A tray or worktop that needs refixing first
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Where we work in St John's
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Failed movement joints
- Expansion joints
Why act early in St John's
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. In a smaller place like St John's, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. In a smaller place like St John's, 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
