Your questions answered
Do you take on work at healthcare sites like The Chiltern Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What sealant do you use in washrooms?
Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Why it’s worth doing now in Great Missenden
A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right while bigger works are planned. Around Great Missenden, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Great Missenden may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

Advice
Commercial washrooms in Great Missenden
Great Missenden lies roughly 30 miles out from central London. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.
Staff changing rooms and patient toilets at places like The Chiltern Hospital, 1.1 miles to the south-east of Great Missenden, need cleanable, sound silicone. Student showers at universities like Buckinghamshire New University (to the south-east of Great Missenden) see more use than most, and their silicone shows it.
Great Missenden is about 4 miles west of Chesham, in Buckinghamshire. Across the HP16 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Buckinghamshire coverage takes in 308 places, large and small. We also cover Reading, some 21 miles away.
If you need washroom sealing in HP16, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Different surfaces, different methods
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. We remove the old bead and lay a fresh one of sanitary silicone.
Changing rooms and gyms
We phase work so not every changing area is closed at once. Phasing follows your site hours and access windows.
Do you need washroom sealing in Great Missenden?
Commercial cleaning is harder on sealant than everyday use. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.
Typical triggers for a call:
- Open joints at the base of cubicle panels
- Split or peeling sealant at shower trays
- Urinal joints that look unhygienic
- Sealant laid over old silicone and now peeling
Schools such as Great Missenden CofE Combined School have toilets, changing rooms and kitchens that are best resealed in the holidays.
