About our washroom sealing in Portsmouth Point
Our washroom work covers offices, hotels, schools and colleges, leisure centres and gyms, clinics and care homes, along with staff kitchens and tea points. Product and method follow how hard each area is used and cleaned. If you are dealing with gaps where vanity tops meet the wall and sealant lifting along a tray edge, we can put it right, on accessible toilets and changing rooms, vanity units and basins and showers, trays and wet room floors alike. Looking for mastic applicators who cover Portsmouth Point? We’ve been sealing commercial buildings since 2005.
A place of Portsmouth Point’s size will typically have a few buildings with commercial washrooms: a school, a surgery, a pub or café, perhaps a care home. They don’t need a big crew, but they do need old sealant fully cut out before anti-mould silicone goes on.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Don’t leave trays and floors sitting wet
- Report split joints at trays and basins early
- Inspect washroom sealant regularly
- Report faulty extraction promptly
Include sealant joints in your planned maintenance checks. Check for mould spots, splits, lifting edges and open joints at trays, basins and urinals and photograph anything new.
Leaks through tray and wet-floor joints can go unseen until a ceiling marks below. At that stage, boards or ceilings may need repair, so reseal when you first spot a split.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Work in places the size of Portsmouth Point is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- Every room is surveyed and the failed joints listed.
- The fixed quote sets out the rooms, the products and the phasing.
- Old sealant is removed completely and the faces cleaned.
- Joints are degreased and dried.
- New anti-mould sealant goes in and is tooled neat.
- Each area is handed back when ready.
Getting the site ready
- Agree which areas must stay open
- For older buildings, check the asbestos register before work
- Arrange parking or a loading space

Related advice
Leave it or put it right?
Waiting for a holiday closure can leave failing joints in place for a long time. Phasing lets it happen now, with facilities kept in use. For buildings in places like Portsmouth Point, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
A quote for washrooms and wet areas depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What else we do in Portsmouth Point
What the job involves on each surface
Wet-room floors and floor-to-wall joints
Floor edges in wet areas are where water most often escapes. Floor perimeters and sealant joints near drains are resealed.
Showers and trays
If a tray moves too much or is cracked, it needs attention first and we flag that beforehand.
Questions we are asked in Portsmouth Point
Do hotels near Portsmouth Point have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.
Is a smaller place like Portsmouth Point outside your area?
Not at all. Portsmouth Point 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.
Do you work in hospitals, clinics and care homes?
Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can you clean the mould off instead of resealing?
Cleaning may lighten it, but the mould returns. New anti-mould sanitary silicone is the treatment and check the ventilation isn’t the cause.
Is there a guarantee on the work?
Every job carries our 12-month guarantee. It covers our workmanship rather than damage, leaks from plumbing or ventilation problems.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Vanity carcasses that have swollen
- Loose panels, vanity units or tiles, which need fixing first
- Mould caused by poor ventilation, which will return until the extract is fixed
If in doubt, phone 01277 525 020 or email drawings and photos and we’ll say what we think.
