Washroom sealing in Cobham
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Maintenance after handover
Keep the joints in good shape with a few simple steps:
- Mention any site permits or estates rules at quote stage
- Brief cleaning staff to treat joints gently
- Include joints in routine washroom inspections
- Make sure washroom ventilation is running
Keep extract fans working and vents clear. Constant damp lets mould take hold even on anti-mould grades, so get faulty extract looked at.
Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.
How we handle washroom sealing in Cobham
From one staff toilet in Cobham to washrooms across a whole estate, the route is the same: send details, get a fixed quote, we seal, guaranteed. Photos and a rough count of basins, urinals, showers and cubicles help us give a quick quote, or we can arrange a visit. If you have open joints at the base of cubicle panels and sealant laid over old silicone and now peeling, we can help, on vanity units and basins, accessible toilets and changing rooms and showers, trays and wet room floors alike. Whoever orders the work in Cobham, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Cobham, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Cobham
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Cobham are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We start by inspecting the fittings and joints and flagging problems sealant can’t solve.
- The phasing is agreed so there are always facilities open.
- The failed silicone is stripped and every face scraped clean of residue.
- We clean and dry every surface so the new sealant can grip.
- New sanitary silicone with anti-mould additives goes in and is tooled neat.
- You get a reopening time for every room, with signage left up until then.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification

Related advice
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, 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 our CSCS-carded applicators are used to working under those rules.
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Cobham can form part of a wider programme across Kent.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Cobham. Several sites can go on one quote, so there’s one set of paperwork to deal with.
How the quote is worked out
Before we quote, we look at:
- Induction, permit and paperwork requirements
- Any access equipment needed
- The total length or number of joints
- Working within restricted access windows
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- Any specification or named product
For a fixed quote, call the office on 01277 525 020 or email drawings and photos with the site address and an outline of the work. Our quote form is another easy route.
Washroom sealing around Cobham: how the place shapes the job
Cobham lies roughly 23 miles out from central London, within the office belt around the capital. Business park offices have washrooms in daily use by staff, so we phase work to keep some facilities open.
For a site such as Gravesham Community Hospital, which lies north-west of Cobham, sanitary joints in clinical areas need sound, cleanable sealant and a careful method. For a college such as North Kent College Gravesend Campus, 3 miles to the north of Cobham, half-term and summer give the windows for washroom work. At a university such as University for the Creative Arts - Rochester (4.9 miles east of Cobham), summer is the usual window for resealing residence bathrooms.
Cobham is about 3 miles south of Gravesend, in Kent. Across the DA12 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 931 places in Kent, large and small. There’s a separate page for London, roughly 23 miles from Cobham.

Questions we’re asked in Cobham
Is hospital work, at somewhere like Gravesham Community Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Cobham too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Can you clean the mould off instead of resealing?
Not for long. Mould grows into the sealant itself, so it comes back however often it’s cleaned. Replacement is the lasting fix.
How long before the toilets can reopen?
Each sealant has a cure time before it should get wet. We plan the phasing around that so facilities are never short.
Are you CHAS accredited?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How much does the work cost?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Vanity carcasses that have swollen
- Failed tanking beneath a wet-room floor or behind tiles
- Mould caused by poor ventilation, which will return until the extract is fixed
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
