About our washroom sealing in Blewbury
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. If you’re dealing with users noticing mouldy joints and resealing that didn’t last because the old bead stayed, we can put it right, on accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles alike. For commercial sealant work in Blewbury, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Rural businesses near smaller places such as Blewbury, from cafés to event venues, rely on washrooms and kitchens that stay clean. Tell us your opening times and quiet periods and we will plan around them.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes half a day to a day per washroom, depending on the number of fittings, and we clear our waste as we work.

- We inspect each washroom and record the joints to be resealed.
- The fixed quote sets out the rooms, the products and the phasing.
- The whole of the old bead is removed.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Avoid scourers and harsh descalers on silicone
- Share your site rules when you send details
- Add sealant joints to planned maintenance checks
- Don’t leave an open joint at a basin or tray
Where possible, have shower floors and trays squeegeed after busy periods. Joints that sit wet for hours fail sooner.
A few failed joints can be resealed with hardly any disruption. Left, it tends to become a building-wide job and more closures to manage.
How the job changes by surface
Wet-room floors and floor-to-wall joints
Changing rooms and accessible showers often have wet floors, so their perimeter joints get close attention.
Basins and vanity tops
Stone and some composite tops need a neutral-cure sealant, so the product is chosen to suit.
Why deal with it now?
Running fresh silicone along a failed bead hides the problem briefly. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Around Blewbury, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Questions about Blewbury
Is hospital work, at somewhere like Didcot Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do we have to close all our washrooms in Blewbury for resealing?
Not all at once. We take one block of facilities at a time. Sanitary silicone needs time to cure before the area is used, and we’ll tell you how long for the product used.
Is Blewbury in your area?
Yes. Blewbury is in our area. For a quote, speak to us on 01277 525 020 or email drawings and photos.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you phase washroom resealing?
Only the area we’re working in is closed. Rooms go back into use once the sealant has cured, then we move on.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
