How the job changes by surface
Healthcare and care settings
We phase washroom sealing so care areas are never left without facilities. Tell us what records you need and we will confirm with the quote.
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm so sealant there works very hard. Anti-mould sanitary silicone is the standard choice.
How we handle washroom sealing in Gustard Wood
In a commercial washroom, sealant is normally the first thing to wear out. Basin tops, urinal backs, panel joints and shower trays put it under water, chemicals and daily cleaning, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. We work on accessible toilets and changing rooms, showers, trays and wet room floors and IPS panels and cubicles, and the usual reasons a site gets in touch are failed sealant in a tea point or staff kitchen and complaints from staff, guests or users about tired washrooms. For commercial sealant work in Gustard Wood, you deal with one contact from quote to sign-off, whether it’s one building or several.
Community buildings around smaller places like Gustard Wood have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Common problems we fix in Gustard Wood
Daily commercial cleaning wears sealant faster than people expect. Harsh products, abrasive pads and pressure washing break down a joint’s surface and edges, and dirt and mould then get a foothold.
Typical triggers for a call:
- Sealant lifting along a tray edge
- Panel joints letting water behind
- Gaps where vanity tops meet the wall
- Sealant laid over old silicone and now peeling
Staff changing rooms and patient toilets at places like Harpenden Memorial Hospital, 2.7 miles to the west of Gustard Wood, need cleanable, sound silicone.

- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?

FAQs: Gustard Wood
Do we have to close all our washrooms in Gustard Wood for resealing?
Rarely all at once: work is phased so some facilities are always available. Each area is handed back once the sealant has cured enough to use.
Is Gustard Wood too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
How do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
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 do washroom sealing in healthcare settings?
We work in clinics, hospitals and care homes. Any records you need are confirmed with the quote.
On site: what to expect
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Rural sites near Gustard Wood may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Every room is surveyed and the failed joints listed.
- You get a fixed quote with the phasing plan.
- Old sealant is removed completely and the faces cleaned.

Before we start on site
