About our washroom sealing in Highstreet
In healthcare and care settings, sealing is part of keeping surfaces cleanable. Your estates and infection-control requirements, and any permits the site uses, shape how we work. Tell us what records you need and we’ll confirm with the quote. Site teams most often ask us about gaps where vanity tops meet the wall and open joints at the base of cubicle panels, on kitchens and tea points, vanity units and basins and IPS panels and cubicles. Searching for sealant specialists in Highstreet? We’ve been sealing commercial buildings since 2005.
Smaller places such as Highstreet still have commercial washrooms and kitchens: in halls, pubs, schools, care homes and farm-based businesses. Sealant that has gone black with mould typically can’t be cleaned, so it is cut out and replaced.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Surface by surface
Urinals and WC pans
Pan and urinal joints face constant cleaning and splashing. Stained or split joints here trap smells and make the room look neglected.
Kitchens and tea points
Worktop, sink and splashback joints in tea points take water and food. Sealed joints leave no gaps for food and dirt.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Don’t leave an open joint at a basin or tray
- Keep extract fans working and vents clear
- Include joints in routine washroom inspections
- Photograph and log failed joints across the estate
Where possible, have shower floors and trays squeegeed after busy periods. Standing water on a joint all day shortens its life.
Mouldy sealant only gets harder to ignore, and complaints follow. Replacing it early keeps the job to a reseal.
Your questions answered
Do hotels near Highstreet have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. The plan is built around your bookings.
Could you schedule work at a campus like University of Kent for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Which silicone is right for commercial washrooms?
Sanitary silicone with anti-mould additives for most washroom joints. We use neutral-cure versions on stone, some metals and near mirrors.
Why it’s worth doing now in Highstreet
Cleaning mouldy sealant only masks it but the growth is inside the bead and returns. A full reseal deals with it and cleaners stop fighting a losing battle. Around Highstreet, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
Why appoint us
- 12 months’ guarantee on every job
- One number for every site we cover
- Old sealant cut out, never sealed over
- A Constructionline member, so easy to vet

What we are called out for in Highstreet
Daily commercial cleaning wears sealant faster than people expect. Strong chemicals, scourers and jet washing roughen, discolour or lift a bead, and dirt and mould then get a foothold.
If one of these sounds familiar, it’s time for a closer look:
- Urinal joints that look unhygienic
- Black mould inside silicone joints that cleaning can’t shift
- Gaps where vanity tops meet the wall
- A new bead over an old one coming away
At a university such as University of Kent, 3.9 miles south-east of Highstreet, summer is the usual window for resealing residence bathrooms.
Questions to ask before you book
- What level of public liability insurance do they hold?
- How the joint faces will be prepared and primed
- Will CSCS-carded applicators be on site?
- Their pre-qualification and accreditations
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Water escaping beneath the floor rather than through a joint
- Leaking pipes, traps, wastes or cisterns, which need a plumber
- Panel boards already damaged by water
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Wet areas in Highstreet’s workplaces
Highstreet is within about 2 miles of the coast, and places by the sea often rely on visitors, so their hotels and holiday lets see heavy seasonal use. Bathrooms turned round daily in the busy months need sound, cleanable joints, which is why off-season resealing makes sense. A 2-mile radius around Highstreet takes in several hotels. Hotel en suites take daily use, and tired silicone at trays and basins is one of the first things guests notice.
For a hotel such as The Crescent Turner Hotel (1.3 miles north-east of Highstreet), resealing en suites a few rooms at a time keeps the rest available. Office toilets at parks like Waterham Business Park, under half a mile west of Highstreet, take steady weekday use, and mouldy silicone soon shows.
