Remedial sealant in Stonor, done properly
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have decorators’ caulk around a bath or shower and floor or wall movement joints that have failed, we can put it right, on failed movement joints, shrunken worktop sealant and botched or over-sealed joints alike.
Around Stonor, it’s 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.
Whatever the size of the job, it’s backed by our one-year guarantee in Stonor and across Oxfordshire.

Landlord and commercial work in Stonor
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured.
Why act early in Stonor
Stripping out botched sealant adds time to a reseal, but not by much: the work 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 Stonor, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- How much there is to do
- The type of sealant required
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
What we need to know
Before you ask for a quote, have a think about:
- Where the property is
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and give you a clear price.
How the visit works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. In a small place like Stonor, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- 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
- Clear items away from the joints we’re working on
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts

Common problems we fix in Stonor
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. At that point it has to come out.
It’s worth asking for a quote if you see:
- A second bead peeling off the first
- Mould trapped under a layer of silicone
- Leaks that keep coming back after resealing
- Smears and lumps from a botched reseal
In and around Stonor, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How long the guarantee is
- How much experience the applicator has
- Whether all the old sealant comes out first
- Whether they’re fully insured
Remedial sealant around Stonor

Your questions about remedial sealant in Stonor
Is Stonor in your area for remedial sealant?

What does remedial sealant cost?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us with a short description of the job.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Tiles that have come away from the wall

- Leaks from a shower valve, waste or pipework (a plumber’s job)
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
