How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take 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 Cockfosters. It helps if you can point us to a visitor permit or a bay close to the door.
- We walk the site with you and agree the rooms, the order and the hours.
- Each area is protected and the old sealant cut out completely.
- The joints are degreased, treated and left to dry.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

How we handle commercial sealant in Cockfosters
In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, working around residents and staff routines. If you have too many rooms to reseal without closing the building and repeated reseals that don’t last, we can help, whatever the surface.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Cockfosters, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Big or small, it’s backed by our 12-month guarantee.

What happens if it’s left?
A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. In London conversions, one flat’s bathroom is often above another flat’s ceiling, 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What commercial sealant looks like in Cockfosters
Cockfosters has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Schools such as Trent CofE Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Christ Church are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

Cockfosters questions
Do you work for hotels and guest houses in Cockfosters?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
I let a flat near New Barnet station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you come to Cockfosters?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you provide RAMS?
Tell us what paperwork your site needs, such as method statements, risk assessments or insurance details, and we will confirm what we can provide when we quote.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
What affects the cost of commercial sealant
Every job gets its own quote. These are the things that affect it:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- How many rooms, windows or areas are involved
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it has been sealed before
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The address or postcode of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, call 0345 464 0079 or email us.
What we are called out for in Cockfosters
Shower trays and baths in busy buildings move more: different weights, constant use and daily cleaning. If a tray flexes, the sealant around it splits.
If you can see any of these, it’s time to have the joints looked at:
- Mouldy washroom sealant that staff and guests notice
- Split sealant where wet room floors meet walls
- Shower leaks reaching the floor below
- Sealant failing again soon after quick repairs
Cockfosters is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Honest limits
We’d rather tell you now than do work that will not last, so these are the limits:
- Water damage behind the tiles that needs a tiler or builder
- Poor ventilation that keeps bringing mould back
- Assessing what fire stopping a building needs
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
