How we handle commercial sealant in Holloway
We fit the work around your building. Rooms can be done one at a time, floor by floor or in batches, and out-of-hours work or early starts can be arranged. If you have tired sealant in let properties and water marks on ceilings under bathrooms, we can put it right.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Holloway cannot close.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How the visit works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours per area, with larger sites planned over several visits. In Holloway, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents 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.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we are working on
- 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 explain how we’d tackle it. When it suits you, call 0345 464 0079 or email us.
Advice
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Common questions in Holloway
Do you work for landlords with property near Drayton Park station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do commercial sealant in Holloway?
Yes. We work across London and the South East, and Holloway is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
What do you put in the joint?
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.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Certifying fire stopping or building compliance
- Water coming from plumbing rather than sealant
- Poor ventilation that keeps bringing mould back
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.
What we seal
- Rental portfolios
- Retail & leisure sites
- Welfare facilities
- Office washrooms & kitchens
- Student & care accommodation
- Hotel bathrooms
What happens if it’s left?
First impressions are often made in the washroom. Mouldy silicone looks unhygienic, however hard housekeeping work, and scrubbing will not fix it. Replacing it does. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

What affects the cost of commercial sealant
For a quick quote, just ask. The main things that affect it are:
- How many rooms, windows or areas are involved
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
To make quoting easier, please include:
- Photos by email, if that is easy
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: tell us what needs doing and where. Photos by email help us understand the job, and we will come back to you with a quote.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Workplaces and buildings in Holloway
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
As a London address, Holloway can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Schools such as Grafton Primary School are buildings too, and sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. If you let a flat or house near Drayton Park station, sealant work can be quoted for a single flat or a whole portfolio.

How to look after the new joints
To keep the joints looking good and working properly:
- Schedule work around occupancy
- Check the joints during routine room inspections
- Encourage users to squeegee shower walls
- Keep a record of which rooms were resealed and when
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Water from a failed shower seal can travel: into ceilings below, walls next door and service voids. Dealing with the joint early stops that spread.
