About our commercial sealant in The Wrythe
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. If you have whole floors of tired en suites and failed floor-level joints in accessible wet rooms, we can put it right, on retail & leisure sites, welfare facilities and hotel bathrooms alike.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In The Wrythe, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Each job carries a 12-month guarantee, large or small.

The process
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to several days, depending on the number of rooms from start to finish. In The Wrythe, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
How to get a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Use mild cleaners on sealant, not bleach or abrasives
- Act on lifting sealant before it leaks
- Note the date each area was done
- Include the silicone on your room checklists
Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints.
It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, rather than closed at short notice.
What happens if it’s left?
First impressions are often made in the washroom. Black sealant makes a clean room look dirty, and scrubbing won’t fix it. Replacing it does. In a flat in The Wrythe, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Questions from The Wrythe
Can you help a landlord with a rental near Carshalton station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover The Wrythe for commercial sealant?
Yes. We work across London and the South East, and The Wrythe is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover The Wrythe, along with the rest of our area.
Can you take on a whole building?
Yes, we can. We work through big sites room by room or floor by floor, so only part of the building is affected at once.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
How long will you be here?
A typical job takes a morning for a small washroom, and a planned programme for bigger sites, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you guarantee commercial jobs?
Yes. Every job, domestic or commercial, carries our 12-month guarantee.
Different surfaces, different methods
Hotel bathrooms
We work through hotel rooms in agreed batches, so most rooms stay available. Housekeeping get a cure time for each room.
Student & care accommodation
In care settings, we agree the order and timings with staff, with each bathroom handed back with its cure time.
Do you need commercial sealant in The Wrythe?
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. A tray that is not fully supported soon tears its seal.
Most people get in touch after spotting one of these:
- Repeated reseals that don’t last
- Split sealant where wet room floors meet walls
- Mouldy washroom sealant that staff and guests notice
- Tired sealant in let properties
Community buildings like Bishop Andrewes Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.
What to look for in a quote
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- Is VAT in the price?
- Is the old sealant removed completely?
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Damaged sanitaryware that needs replacing
- Assessing what fire stopping a building needs
- Water coming from plumbing rather than sealant
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Commercial sealant around The Wrythe
London’s water is hard, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.
The Wrythe is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For site and facilities teams at buildings such as Victor Seymour Infants' School, washroom and kitchen sealant can be programmed around term times or opening hours.
