Coloured sealant for commercial buildings in Canonbury
Architects, designers and brand teams often specify the sealant colour as carefully as the finishes around it. Most sealant types are made in a broad range of standard colours, so we check what the specified product is made in at quote stage. An exact bespoke match can’t always be promised, so we talk you through the nearest colours. If you are dealing with discoloured joints on a visible elevation and untidy coloured beads with ragged edges, we can put it right, whatever the surface. Searching for sealant specialists in Canonbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In London, most commercial sealant work happens in buildings that stay open: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Materials with mixed tones that defy a single match
- Paintable products in joints they aren’t suited to
- Preventing all fading from sunlight and weathering

Common problems we fix in Canonbury
When frames are recoated or a space is rebranded, the old joints may no longer suit. New cladding colours, repainted frames or a refreshed shop fit all prompt colour changes, and the joints need to match.
Clients typically get in touch after noticing one or more of the following:
- White or grey sealant that clashes with the finish
- Old sealant that has yellowed, darkened or faded
- Untidy coloured beads with ragged edges
- Patch repairs in several different colours
Units at places like Brunswick Centre, 2.1 miles to the south-west of Canonbury, are refitted as brands change, and the joints have to suit each new scheme.
Questions to ask before you book
- Who will actually carry out the work
- How they’ll work around occupants
- Their approach to joint depth and backing
- Their pre-qualification and accreditations
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and we clear our waste as we work. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The sealant type is chosen for the joint first, then the colour.
- Colour references, samples or photographs of the finish are checked against the product’s range.
- Where colour is critical, a sample bead can be agreed in a discreet spot.
- We take out the existing bead, clean the joints and fit backing.
- The coloured sealant is applied and tooled with clean, masked edges.
Getting the site ready
- Send your site hours and access windows
- Have the specification and drawings to hand
- Flag any permit to work we’ll need

Advice
How the job changes by surface
Shop-fit and joinery finishes
Counters, display units and wall linings are seen close up. Clean masking and neat tooling matter as much as colour.
Cladding panels
Multi-coloured cladding needs a joint colour that works across it. A neutral tone from the range often works best and we can trial it first.
Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Work for main contractors and building owners
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.
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
