Remedial sealant for homes and businesses in Witney
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. If you’re dealing with caulk or the wrong sealant used in a wet area and worktop sealant that has shrunk and split, we can help, on shrunken worktop sealant, expansion joints and botched or over-sealed joints alike.
Homes around Witney have been extended and refitted over the decades, some more than once. A common problem is new sealant laid over old, which never bonds properly, so we take every joint back to clean before anything new goes in.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from Witney
Is Witney in your area for remedial sealant?
Yes. We work across London and the South East, and Witney is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.
Can you help a landlord with a rental near Finstock station?

Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How long will it take to strip and reseal the joint?
Allow a few hours for most joints, depending on how much old sealant has to come out. We will give you a timescale when we quote.
My shower still leaks after a reseal. Can you sort it?
Yes. We will take all the sealant out, look for why it failed and reseal it properly.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
What happens if the problem is the tray or the plumbing?

Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Why act early in Witney
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out. In a family home in Witney, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
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 play a part, and we’ll explain the quote if you ask.
What you get with us
- Anti-fungal silicone where joints get wet
- Fully insured
- A 12-month guarantee on all work
- Trusted Arbo and Everbuild sealants

Remedial sealant in Witney: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Witney has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as Witney Congregational Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as Tower Hill Community Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Finstock station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and letting agents in Witney can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Never seal over old silicone
- Keep the room well ventilated
- Find out why the sealant failed first
- Clean sealant with mild products only
Clean gently: no scraping, scouring pads or harsh chemicals.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
