Washroom sealing for commercial buildings in Long Crendon
Facilities managers, contractors and building owners have used us for washroom sealing for over 20 years. We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. There is public liability insurance behind every job. Every resealed washroom carries our 12-month guarantee. We work on showers, trays and wet room floors, kitchens and tea points and vanity units and basins, and the failures we’re asked to look at most are open joints at the base of cubicle panels and sealant laid over old silicone and now peeling. One point of contact handles commercial sealant work in Long Crendon from the first photographs to the final walk-round, whether it’s one building or several.
A place of Long Crendon’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. However small, each needs the old sealant removed completely and anti-mould sanitary silicone applied to clean, dry joints.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Long Crendon
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Water from plumbing, not from a joint
- Panel boards already damaged by water
- Leaks through tanking or membranes below the finishes
Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we will tell you honestly.
Surfaces we seal
- Showers, trays and wet room floors
- Accessible toilets and changing rooms
- Kitchens and tea points
- Urinals and WCs
- IPS panels and cubicles
- Vanity units and basins
Leave it or put it right?
Sealing on top of old silicone saves nothing. It doesn’t bond, so it peels and traps dirt behind it. Full removal and proper cleaning is what makes the new joint last. Small buildings around Long Crendon suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sanitary sealant for Long Crendon buildings
A 2-mile radius around Long Crendon takes in a number of hotels. Each has en suites, back-of-house toilets and kitchens with sealant that moulds and splits. Long Crendon is about 43 miles from central London, in a commuter belt where offices and business parks are common. Washrooms in commuter-belt offices take constant weekday traffic, and resealing in phases keeps facilities available.
Pupil toilets at schools like Long Crendon School take heavy daily use, and the holidays give the window to reseal. Clinical washrooms at sites like Thame Community Hospital, 2.4 miles south-east of Long Crendon, are scheduled with the ward so the room is out of use for as little time as possible. Units at estates like Crendon Industrial Estate, 0.9 miles south-east of Long Crendon, have welfare blocks whose showers and toilets see shift after shift.

Questions about Long Crendon
Is Long Crendon off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you take on work at healthcare sites like Thame Community Hospital?
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.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Is old silicone taken out first?
We always remove it. Fresh silicone can’t key to an old bead, so sealing over it soon peels.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes between a morning and a week or so, set by the number of rooms and the phasing you need. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Doing it in-house
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.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Different surfaces, different methods
Changing rooms and gyms
Changing rooms in gyms and leisure centres stay wet and warm, so mould is a constant battle. Anti-mould sanitary silicone is the standard choice.
IPS and cubicle panels
A panel that has already swollen won’t be fixed by sealant and we will point out any we see.
How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Long Crendon, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
