Is parking an issue for commercial sealant in Chalk Farm?
Parking in Chalk Farm, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How long will you be here?
As a guide, most jobs take a morning for a small washroom, and a planned programme for bigger sites. Bigger jobs take longer.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Do you take on large, multi-room jobs?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Commercial sealant in Chalk Farm, done properly
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, applied by ARBOMaster approved applicators. We are often asked to deal with washrooms that need sorting before an inspection and silicone laid over old silicone by a previous contractor, on student & care accommodation, welfare facilities and hotel bathrooms.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. In Chalk Farm, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Big or small, it’s backed by our 12-month guarantee.

Commercial sealant around Chalk Farm
Chalk Farm has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
For buildings such as St Silas Church, its kitchen and washroom sealant needs looking after like anywhere else. As a London address, Chalk Farm can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Chalk Farm is about 1 mile south-east of Hampstead, in Greater London. Wherever you are in the NW5 postcode area, our applicators can take on commercial sealant. Chalk Farm is one of 764 towns and villages in Greater London where we work for commercial sealant.

You’ll also find Holy Trinity and Saint Silas CofE Primary School (less than half a mile east) and North Bridge House School (0.5 miles south-east).

Why act early in Chalk Farm
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We will tell you if we find anything that needs another trade. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Chalk Farm, the repair is bigger than a sealant job.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

How the job changes by surface
Retail & leisure sites
Retail and leisure sites have washrooms, kitchens and changing areas with sealant to maintain. Work can be arranged outside opening hours where that is possible.
Student & care accommodation
Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured.
Signs you need commercial sealant in Chalk Farm
In an accessible wet room, water spreads across the floor every use, so floor-to-wall joints take standing water. Any split there can let water through quickly.
Common reasons people contact us are:
- Tired sealant in let properties
- Silicone laid over old silicone by a previous contractor
- Joints that need doing before an inspection or audit
- Water marks on ceilings under bathrooms
For site and facilities teams at buildings such as Haverstock School, washroom and kitchen sealant can be programmed around term times or opening hours.

The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It usually takes a few hours for a single washroom, longer for a whole building. In a London area like Chalk Farm, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- The first visit is a look round the site to agree the scope.
- We agree when we will work, with early or out-of-hours slots where they 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

What affects the quote in Chalk Farm
You will get a clear quote before work begins. It’s based on:
- Access and height

- The old material and how stubborn it is
- Any working-time requirements on site
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.
Helping us quote
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
