Remedial sealant & repairs in Marsh Gibbon, Oxfordshire
Our applicators work in Marsh Gibbon on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps opening along the back of the worktop
- Products that weren’t meant for the joint
- Sealant applied over old sealant that has lifted
Why deal with it now?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In a small place like Marsh Gibbon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
Why us?
- Tidy, careful work
- Any old sealant cut out fully, not covered over
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme

Remedial sealant in Marsh Gibbon
A joint that keeps letting you down needs more than another bead. Send photos when you call 0345 464 0079 or drop us an email, and say how long ago it was last done. If you have decorators’ caulk around a bath or shower and floor or wall movement joints that have failed, we can help, on shrunken worktop sealant, failed movement joints and mouldy bath & shower sealant alike.
Homes around Marsh Gibbon are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
Our work is backed for twelve months.

Quotes for remedial sealant in Marsh Gibbon
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- The size of the job
- Access and height
- Mould in or behind the old joints
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- The rough size of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.

Different surfaces, different methods
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, in a colour that suits the frame.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like Marsh Gibbon needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Marsh Gibbon questions
Do you work for landlords with property near Bicester North station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Do you cover Marsh Gibbon for remedial sealant?
Yes. We work across London and the South East, and Marsh Gibbon is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear price.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What happens if the problem is the tray or the plumbing?
In that case, we tell you what we have found. A plumber or fitter may be needed before any new sealant goes on.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, especially on acrylic, enamel and uPVC.
Can I do it myself?
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. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Marsh Gibbon homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Managing a site like Marsh Gibbon CofE Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.

When to call us in Marsh Gibbon
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Any of these means the joints need attention:
- Worktop sealant that has shrunk and split
- Torn expansion joints
- Beads that never stuck properly
- Dark patches showing through the sealant
If you let a flat or house near Bicester North station, a joint that keeps failing is best fixed properly while the property is empty.
