Remedial sealant for homes and businesses in Whitchurch-on-Thames
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. Typical jobs include worktop sealant that has shrunk and split and smears and lumps from a botched reseal, across expansion joints, botched or over-sealed joints and shrunken worktop sealant.
Somewhere as small as Whitchurch-on-Thames, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
All our work comes with a one-year guarantee, wherever you are in Oxfordshire.

Surface by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Whitchurch-on-Thames: your questions answered
Do you work in hotels near Whitchurch-on-Thames?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you cover smaller places like Whitchurch-on-Thames?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does the work take?
Allow a few hours for most joints, depending on how much old sealant has to come out. You will know the timing when we quote.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is remedial work guaranteed?
Yes. You get our 12-month guarantee, and we’re fully insured.
Can you remove sealant that is been put over old sealant?
Yes. We remove every layer; new silicone does not bond to old silicone, which is why over-sealing fails.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the 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 it works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. In a small place like Whitchurch-on-Thames, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.

When to call us in Whitchurch-on-Thames
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
The problems people normally mention when they call include:
- Black mould underneath the bead
- Kitchen joints letting water behind the worktop
- Repeat leaks from the same joint
- Decorators’ caulk around a bath or shower
If you live in an older home near Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep movement joints clear of mortar and paint
- Get the cause of a repeat leak found before resealing
- Look for stains below bathrooms now and then
- Clean sealant with mild products only
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
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.
