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
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Note failing joints building by building
- Avoid scourers and harsh descalers on silicone
- Act on the first split you see at a shower tray
- Share your site rules when you send details
Ventilation is half the battle. Constant damp lets mould take hold even on anti-mould grades so report fans that aren’t working to your building services team.
A split joint at a shower tray can leak for a long time before anyone sees it. At that stage, boards or ceilings may need repair so failed joints are worth acting on quickly.
How we handle washroom sealing in Newchurch
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. There is public liability insurance behind every job. Our workmanship is guaranteed for 12 months. The enquiries we see most involve black mould inside silicone joints that cleaning can’t shift and open joints along basins and vanity units, across vanity units and basins, accessible toilets and changing rooms and showers, trays and wet room floors. One point of contact handles commercial sealant work in Newchurch from the first photographs to the final walk-round, whether it’s one building or several.
Community buildings around smaller places like Newchurch have kitchens and toilets used by many people. Resealing sinks, worktops and WCs with anti-mould silicone keeps them clean and watertight.
Every job we finish is backed by a 12-month workmanship guarantee, in Newchurch as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
What we are called out for in Newchurch
Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.
Common reasons buildings call us in:
- Sealant lifting along a tray edge
- Washrooms that look worn because of the sealant
- Resealing that didn’t last because the old bead stayed
- Sealant stained black around basins and showers
Office washrooms on sites such as Langbridge Business Centre (to the north-west of Newchurch) are in use all working day, so resealing is phased to keep some open.
Questions to ask before you book
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- What site paperwork they can supply
Sanitary sealant for Newchurch buildings
Newchurch sits close to the coast, within about 3 miles, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Showers and en suites in constant use are where silicone moulds and splits first, so we plan the work for quieter weeks where possible.
For a hall at a building such as All Saints' Church, resealing the kitchen and toilets can be fitted between bookings. Schools such as Newchurch Primary School have toilets, changing rooms and kitchens that are best resealed in the holidays.

How a job runs
We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Newchurch may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- 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.
- Failed silicone is removed completely and the surfaces cleaned of every trace.
- Each joint is degreased and left dry, because silicone won’t bond to damp or soapy surfaces.
- We lay a sanitary silicone bead and tool it smooth so it is easy to clean.
- You get a reopening time for every room, with signage left up until then.
Preparing the site
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached
- Share your working hours and any access restrictions
Getting a fixed quote
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
Advice
Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
- A dripping waste or valve behind a panel
If you’re not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
Surfaces we seal
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Kitchens and tea points
- Urinals and WCs
- Vanity units and basins
- IPS panels and cubicles
What happens if it’s left?
A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. That can lead to swollen boards, marked ceilings below and lingering smells, and fixing that takes far more work than resealing. Around Newchurch, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
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.

FAQs: Newchurch
Can you work on a hospital site such as Arthur Webster Memorial Hospital for Children?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is a smaller place like Newchurch outside your area?
Not at all. Newchurch is within our area. 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.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
What if there’s asbestos in the old mastic?
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. We don’t remove asbestos-containing materials.
