Why it’s worth doing now in California
A tired washroom says a lot about how a building is run. Visitors notice black sealant even when the room is otherwise spotless. Fresh sanitary silicone lifts a room with very little disruption. One visit to deal with every failing joint makes more sense than several trips to a place like California, rather than one at a time. Photos of every joint help us quote for the whole job.
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.

About our washroom sealing in California
Washroom joints need the right sealant, not whatever is to hand. Sanitary silicone contains additives that resist mould, and neutral-cure versions avoid the damage acetoxy types can do to some metals, stone and mirror backings. In food areas, hygienic or food-safe sealants are used where food contact is possible. If you have users noticing mouldy joints and gaps where vanity tops meet the wall, we can put it right. For commercial sealant work in California, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Farm shops, cafés and venues in converted rural buildings around places like California have busy toilets and kitchens. We plan the work around bookings and opening times.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Questions about California
Do we have to close all our washrooms in California for resealing?
Rarely all at once: work is phased so some facilities are always available. Sanitary silicone needs time to cure before the area is used, and we will tell you how long for the product used.
Do you take on work at healthcare sites like Wokingham Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Is California in your area?
Yes. Sites across California are covered, with one number for every area we cover.
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 there are always rooms open.
Do you phase washroom resealing?
The work is phased so users always have somewhere to go. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around California, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We agree which washrooms close and when.
- Anything behind the joints that needs another trade is flagged.
- Failed sealant and residue are stripped out.
- We reseal with the grade suited to each area.
- We give you a reopening time for every room.
Before we start on site
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected

Honest limits
Some faults sit outside our scope, and we say so rather than covering them up:
- Mould caused by poor ventilation, which will return until the extract is fixed
- Hollow tiles or loose panels behind the joint
- Failed tanking beneath a wet-room floor or behind tiles
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Joints and surfaces we work on
- Vanity units and basins
- Showers, trays and wet room floors
- Urinals and WCs
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
Different surfaces, different methods
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms, so their perimeter joints get close attention.
Changing rooms and gyms
Showers, floor edges and vanity units in changing rooms all need sound sealant, and we survey them together.
What we are called out for in California
Decorators’ caulk and general sealants sometimes end up where sanitary silicone belongs. They don’t stand up to constant water and they discolour and fail early.
Site and facilities staff are often the first to spot these:
- Sealant lifting along a tray edge
- Open joints along basins and vanity units
- Discoloured joints around urinals and WC pans
- Black mould inside silicone joints that cleaning can’t shift
Where you are responsible for a hall attached to a building such as Church of St James, its kitchen and toilets need sealant that stays cleanable.
