Commercial & hotel sealant in Dunn Street, Medway
Our applicators work in Dunn Street on sealant work for offices, hotels, washrooms and commercial buildings. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

Why act early in Dunn Street
Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we will say so. Where a wall is exposed, as many are in small places like Dunn Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

How we handle commercial sealant in Dunn Street
Office kitchens, staff washrooms and welfare facilities need to be usable every working day. We can plan the work for early mornings or out of hours to keep disruption down. You’re told when each area can be used again. We work on rental portfolios, student & care accommodation and hotel bathrooms, and common reasons people get in touch are worktop sealant that has shrunk and stained and large numbers of bathrooms needing the same work.
For a small place like Dunn Street, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
There’s a 12-month guarantee on every job.

Dunn Street questions
Do you cover smaller places like Dunn Street?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Rainham (Kent) station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Dunn Street, along with the rest of our area.
How long does the job take?
A typical job takes a few hours for a single washroom, longer for a whole building, including preparation and clearing up. We will confirm how long when we quote.
Can you work around guests in a hotel?
Yes, in most cases. We agree a batch of rooms for each visit, working around check-out and check-in where possible.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
What sealant work cannot fix
We will not take on work that won’t last, so here’s what sealant cannot put right:
- A shower tray, bath or basin that’s cracked or broken
- Poor ventilation that keeps bringing mould back
- Fire risk assessments or certification
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Workplaces and buildings in Dunn Street
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as Church of St Peter, any kitchen and washrooms need the same sealant care as any other building. Schools such as Swingate Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open. If you let a flat or house near Rainham (Kent) station, we can quote for one property or a whole portfolio of rentals.

The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours per room, so whole buildings are phased. Somewhere as small as Dunn Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with a site walk to agree the rooms and the timing.
- Every area is sheeted and the old silicone stripped out.
- The joints are degreased, treated and left to dry.
- We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
- Each room is checked and handed back with its cure time.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Advice
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Leave squeegees in busy showers
- Tell cleaning staff when each room can be used
- Log resealing so you know what’s due
- Use mild cleaners on sealant, not bleach or abrasives
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
