About our washroom sealing in Caversham
Washroom joints need the right sealant, not whatever is to hand. Sanitary grades carry anti-mould additives, and neutral-cure types are used where acetoxy silicone could attack some metals, stone or mirror backings. Where food contact is possible, we use a hygienic, food-safe grade. The enquiries we see most involve panel joints letting water behind and stained sealant around pans and urinals, across urinals and WCs, vanity units and basins and showers, trays and wet room floors. For commercial sealant work in Caversham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Schools in towns like Caversham usually want washrooms and changing rooms done in the holidays, while offices and care homes need phased work. Let us know your opening times and any access limits, and we will work to them.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- The site’s rules and procedures
- Any access equipment needed
- Joint width, depth and condition
- Which sealant the job calls for
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- The site address and postcode
- Access details, including height
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or email the details over.
Why it’s worth doing now in Caversham
Bleaching black sealant may lighten it for a few days but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. Many buildings in towns like Caversham have been extended or altered, so joints between old and new are often the first to go. Resealing them early protects the building behind.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What the job involves on each surface
Changing rooms and gyms
Gym and leisure changing rooms see showers running most of the day, so mould is a constant battle. We use anti-mould sanitary silicone throughout.
Urinals and WC pans
We reseal around urinals and pans with a sanitary grade after the old bead and residue are removed.

What else we do in Caversham
What we are called out for in Caversham
Cubicle panels, IPS panels and vanity units flex when people lean on them or doors are slammed and trays shift slightly with each user. A bead that can’t cope with the movement splits along one edge.
Any of the following is a good reason to get the joints checked over:
- Panel joints letting water behind
- Shower tray joints that have opened up
- Users noticing mouldy joints
- Sealant laid over old silicone and now peeling
At a hospital like Royal Berkshire Hospital, 2 miles to the south of Caversham, patient and staff washrooms are best done in short phases agreed with the ward.

Office toilets in the commuter belt are in use from first arrivals to last departures, so we work a block of facilities at a time. A 2-mile radius around Caversham takes in plenty of hotels.

Questions we’re asked in Caversham
Can you work around term dates at a campus such as University of Reading?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do hotels near Caversham have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Is Caversham in your area?
Yes. Caversham is in our area and the rest of Reading. To discuss a job, speak to us on 01277 525 020 or email us.
Do you guarantee washroom sealing?
A 12-month guarantee covers the work. It applies to our workmanship, not to plumbing leaks or damp from poor ventilation.
How soon can a washroom be used after resealing?
Each sealant has a cure time before it should get wet. Phasing is planned with the cure time in mind so facilities are never short.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What sealant do you use in washrooms?
An anti-mould sanitary silicone in the majority of cases. Neutral-cure grades are used where acetoxy types could mark metals, stone or mirror backings.
