Commercial & hotel sealant in Northwood, Isle of Wight
Commercial sealant for Northwood, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

- Failed floor-level joints in accessible wet rooms
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
How we handle commercial sealant in Northwood
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. If you have mouldy washroom sealant that staff and guests notice and failed joints in office kitchens and tea points, we can put it right, whatever the surface.
For a small place like Northwood, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Surface by surface
Rental portfolios
Good sealant prevents leaks that cause bigger repairs.
Student & care accommodation
Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Note the date each area was done
- Include the silicone on your room checklists
- Put a squeegee in each shower
- Act on lifting sealant before it leaks
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints.
A room that can’t be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
Questions from Northwood
Do you work for hotels and guest houses in Northwood?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Is Northwood in your area for commercial sealant?
Yes, Northwood is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is out-of-hours working possible?
Often, yes. Let us know when the building is quietest, and we’ll see what can be arranged.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or drop us an email.
What we cannot put right
We will always be straight with you, so here’s what new sealant won’t do:
- Cracked trays or baths rather than failed joints
- Faulty shower valves and leaking traps
- Poor ventilation that keeps bringing mould back
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

- Hotel bathrooms

Commercial sealant in Northwood: local notes
If you run a hotel, guest house or holiday let in a coastal place like Northwood, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you look after a church, hall or community building such as All Saints' Church, halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as Northwood Primary School, washroom and kitchen sealant can be programmed around term times or opening hours.

Why deal with it now?
Fixing rooms one complaint at a time is the slow way. A planned programme deals with every room in order, keeping disruption down and costs clear. Around Northwood, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
