About our commercial sealant contractors in Chalk Farm
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you’re dealing with leaks that seem to come through a sealant line and untidy joints in a reception, shop floor or lobby, we can help, on movement joints in walls and floors, washrooms and tea points and floor and threshold joints alike. A single leaking joint is often how a building in Chalk Farm first comes to us: we look at the rest while we’re there and tell you what we find.
We price commercial jobs in Chalk Farm from photos, drawings or a site visit, and the scope is set out in writing.
In London, most commercial sealant work happens in buildings that stay open: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Shops, offices and hotels in and around Chalk Farm
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We work within them, one zone at a time. At least three named trading, business or retail sites lie within about 3 miles of Chalk Farm. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.
For a shop at a centre such as O2 Centre, 1.3 miles west of Chalk Farm, tidy joints at counters and displays matter as much as the fixtures. For premises near Kentish Town West station, under half a mile north-east of Chalk Farm, footfall is part of the plan: work is phased so shops and offices keep trading.
Chalk Farm is about 1 mile south-east of Hampstead, in Greater London. We cover commercial sites throughout Chalk Farm. Chalk Farm is one of 764 places we cover in Greater London.
We cover the NW5, NW1 and NW3 postcode districts. If your site is on Eton Road, Oval Road and Regal Lane or close by, we can quote for sealant joints.

Cost factors for sealant joints
We price every job individually. The main factors are:
- How accessible the joints are
- Distance, for remote addresses
- How much there is to seal
- Backing rod, priming and other preparation
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Sending details for a quote
However big the job, the same details help:
- Your programme or deadline
- Photos of the joints, close up and from further back
- The postcode of the building
- The type of building and who uses it
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

How the job changes by surface
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing.
What happens if it’s left?
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, which is where the lasting value is. Failed sealant in a building in Chalk Farm can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When to call us in Chalk Farm
Every sealant joint is a maintenance item. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once, which is why regular inspection pays.
What tends to prompt an enquiry:
- Earlier reseals applied straight onto the failed bead
- Water staining near frames, panels or ceilings
- Smeared sealant across finishes from a rushed job
- External beads that have gone brittle and cracked
In hotels such as Camden Lock Hotel, under half a mile north-west of Chalk Farm, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
What your quote should include
- Will failed sealant be removed rather than covered?
- The terms of the workmanship guarantee
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Chalk Farm: questions and answers
Do you cover business parks and estates near Chalk Farm, such as Regis Road Business Park?
Yes. We cover Chalk Farm and the area around it, including industrial estates, business parks and retail parks such as Regis Road Business Park. Photos and a short description are enough for a first look.
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Will the building have to shut during the work?
Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.
Can you supply RAMS and insurance details?
Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What guarantee do you give on resealing?
Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. All of Greater London is in the ULEZ, and kerbside space in Chalk Farm can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, details come to us: photos, drawings or a schedule of the areas.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Send your site hours and access windows
- Have the specification and drawings to hand
