What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Water from plumbing, not from a joint
- Loose panels, vanity units or tiles, which need fixing first
- Water escaping beneath the floor rather than through a joint

About our washroom sealing in Walkern
Black spotting along a sealant bead is not a cleaning problem. The mould has rooted into the silicone itself so it returns whatever the cleaning regime. Replacing the bead is the lasting treatment. The enquiries we see most involve a new bead over an old one coming away and urinal joints that look unhygienic, on kitchens and tea points, showers, trays and wet room floors and IPS panels and cubicles. Looking for mastic applicators who cover Walkern? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Smaller places such as Walkern still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Mould gets into sealant in any washroom that doesn’t dry out, and once it’s in, the sealant is replaced.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Your questions answered
Is a smaller place like Walkern outside your area?
No. Places such as Walkern are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on work at healthcare sites like Lister Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How do we ask for a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Toilets, showers and kitchens around Walkern
Central London is about 29 miles from Walkern, within the office belt around the capital. 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.
Office washrooms on sites such as Astonbury Farm & Business Park, 2.7 miles to the south of Walkern, are in use all working day, so resealing is phased to keep some open. Church halls and community buildings, such as those at Parish Church of St Mary the Virgin, have kitchens and toilets used by many groups, and their sanitary sealant works hard.

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a morning or so for a small washroom, longer where showers and changing rooms are included, and our waste is bagged and taken away as we go. Rural sites near Walkern may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We agree which washrooms close and when.
- Leaks, loose panels or damp are pointed out first.
- Failed sealant and residue are stripped out.
- The right sanitary or food-safe sealant is applied.
- We confirm reopening times for each washroom.
Preparing the site
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
Ask for a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

When to call us in Walkern
Sometimes the sealant fails because something behind it is moving or wet: loose fixings, a dripping trap or damp in the wall. We check for that first and say if it needs a plumber or another trade.
Clients usually get in touch after noticing something like this:
- Discoloured joints around urinals and WC pans
- Panel joints letting water behind
- Resealing that didn’t last because the old bead stayed
- Mould spotting along silicone joints
Pupil toilets at schools like Walkern Primary School take heavy daily use, and the holidays give the window to reseal.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Leave it or put it right?
Open or mouldy joints are hard to keep hygienic, and in kitchens, clinics and schools that is a real concern. A smooth, sealed joint can be cleaned properly. Around Walkern, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
