Remedial sealant in Dean Court
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. Finding that cause comes before any new sealant. If you have mould trapped under a layer of silicone and a shower that leaks however often it’s resealed, we can help.
Around Dean Court, you’ll mostly find houses and bungalows, from older cottages to newer builds. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
There’s a 12-month guarantee on every job.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Dean Court, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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
- Let us know about earlier repairs to the joints
- Clear the area around the work

Advice
When to call us in Dean Court
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. Each fails in its own way.
Look out for these signs:
- Leaks that keep coming back after resealing
- A second bead peeling off the first
- Movement joints that have split or pulled away
- Mould trapped under a layer of silicone
For landlords with property near Oxford station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- Whether VAT is included
- How the colour is chosen
- How much experience the applicator has
- When the joint can take water or movement
Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Get the cause of a repeat leak found before resealing
- Air the bathroom so the sealant can dry
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.

How the job changes by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.
More services for Dean Court
What remedial sealant looks like in Dean Court
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
For site and facilities teams at buildings such as Matthew Arnold School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to St Andrew's include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
