Washroom sealing in St Mary Bourne
In a commercial washroom, sealant is normally the first thing to wear out. Around basins, urinals, cubicles, IPS panels and shower trays it takes water, soap, cleaning chemicals and knocks every day, and once mould grows into it, it can’t be scrubbed out. We strip it out and lay new anti-mould sanitary silicone. Site teams most often ask us about resealing that didn’t last because the old bead stayed and discoloured joints around urinals and WC pans, across accessible toilets and changing rooms, urinals and WCs and IPS panels and cubicles. Whether you call it commercial sealant work, mastic application or joint sealing, the work in St Mary Bourne is the same: the right product in a properly prepared joint.
Smaller places such as St Mary Bourne still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?
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. One visit to deal with every failing joint makes more sense than several trips to a place like St Mary Bourne, rather than one at a time. Photos of every joint help us quote for the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Toilets, showers and kitchens around St Mary Bourne
St Mary Bourne lies roughly 59 miles out from central London, in a commuter belt where offices and business parks are common. Office toilets in the commuter belt are in use from first arrivals to last departures, which is why the work is phased.
At a school such as St Mary Bourne Primary School, changing rooms and kitchens need cleanable joints as much as the toilets. Halls linked to places like Church of St Peter host groups all week, which is hard on kitchen and toilet sealant.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Loose panels, vanity units or tiles, which need fixing first
- Panel boards already damaged by water
- Leaks through tanking or membranes below the finishes
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
What we seal
- Vanity units and basins
- Kitchens and tea points
- Accessible toilets and changing rooms
- IPS panels and cubicles
- Urinals and WCs
- Showers, trays and wet room floors
What we’re called out for in St Mary Bourne
Low-level joints get hit by mop buckets, cleaning trolleys and feet at skirting lines, urinal bases and around pans.
Site and facilities staff are often the first to spot these:
- A new bead over an old one coming away
- Failed sealant in a tea point or staff kitchen
- Users noticing mouldy joints
- Stained sealant around pans and urinals
Healthcare washrooms on sites such as Andover War Memorial Hospital (4.9 miles south-west of St Mary Bourne) are resealed area by area, under the site’s own infection-control rules.
Comparing quotes
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?
- Which product they’ll use, and why it suits the joint
- How joint depth will be controlled
General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: 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.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Distance, for remote addresses
- Whether old sealant has to be cut out first
- The total length or number of joints
- The product specified
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- Whether an asbestos survey exists
- What the building is and how it’s used
- When you need the work done
- Anything awkward about access or site hours

Common questions from St Mary Bourne clients
Is St Mary Bourne too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you take on work at healthcare sites like Andover War Memorial 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.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How do you deal with asbestos in old sealant?
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.
Is there a guarantee on the work?
A 12-month guarantee covers the work. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
