About our commercial sealant in Upper Holloway
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. If you are dealing with water marks on ceilings under bathrooms and too many rooms to reseal without closing the building, we can help.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Upper Holloway, and room-by-room programmes can be planned where needed.
There’s a 12-month guarantee on every job, whatever its size.

What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per room, so whole buildings are phased. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Upper Holloway. It helps if you can point us to a visitor permit or a bay close to the door.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Rooms are handed back in order, each with its cure time.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Questions from Upper Holloway
Can you do commercial sealant in Upper Holloway?
Yes, Upper Holloway is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Upper Holloway station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
Can you reseal every bathroom in a hotel?
Yes. After a site walk, we agree the scope and sequence, and you get one clear quote.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Why act early in Upper Holloway
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and scrubbing will not fix it. Replacing it does. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
Why us?
- Experience in homes, commercial sites and hotels
- Sanitary silicone with an anti-fungal additive in wet areas
- We agree the colour with you first
- Every job guaranteed for a year
What we are called out for in Upper Holloway
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning all work at the joint. If a tray flexes, the sealant around it splits.
Signs it’s time to call us include:
- Split sealant where wet room floors meet walls
- Rental bathrooms that need resealing between tenants
- Shower leaks reaching the floor below
- Washroom sealant that looks dirty however often it’s cleaned
Community buildings like St Andrew's Whitehall Park are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the cost of commercial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- Whether there’s mould to deal with
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Helping us quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- If someone has resealed it before
- Where the job is, and your postcode
- Photos by email, if that’s easy
Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we will come back to you with a quote.
