About our coloured sealant in City of London
Shop fits, hotels and offices are where colour-matched sealant earns its place. A mismatched bead can make good joinery look unfinished. We pick a colour from the product’s range that sits with the finish. Most enquiries involve poorly tooled joints on visible finishes and previous reseals that don’t match the original, across powder-coated and anodised frames, natural stone and brick and hotel bathrooms and public areas. One point of contact handles commercial sealant work in City of London from the first photographs to the final walk-round, for single jobs and planned programmes alike.
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. 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. Should something we installed fail, phone 01277 525 020 or use the quote form and we will come back to it.

Cost factors for colour-matched joints
Each job is priced on its own details. The things that drive the figure:
- How accessible the joints are
- Whether the work must be split into stages
- How much there is to seal
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- The product your specification calls for
- Photos of the joints, close up and from further back
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What we are called out for in City of London
Joints repaired piecemeal often end up in several shades. Different products and batches used over the years leave a patchwork along a shopfront. Resealing a whole run in one agreed colour tidies it up.
Look out for the following:
- Colour changes after a rebrand or refit
- Previous reseals that don’t match the original
- Stained or mouldy coloured joints in washrooms
- White or grey sealant that clashes with the finish
Premises within reach of London Cannon Street station, under half a mile to the south of City of London, often have busy frontages where joints are seen by everyone passing.
Before you book anyone
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
- What site paperwork they can supply
- Do they follow the manufacturer’s priming guidance?
Working on commercial sites near City of London
City of London has three care or nursing homes no more than 2 miles away. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. Less than 3 miles from City of London there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it.
Shopping centres and retail parks such as Brunswick Centre, 1.5 miles to the north-west of City of London, see a steady turnover of shop fits, each leaving joints where colour and finish matter. A hotel such as Clayton Hotel London Wall, less than half a mile north-east of City of London, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
City of London is about 1 mile north of London, in City of London. Anywhere in EC4V, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 7 places in City of London, large and small.
If you need coloured sealant in EC4V, EC1A, EC2M and EC2Y, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

City of London sits on or close to the A1 and A3, useful when we plan access and materials. Nearby places we also cover include Barbican Estate (1 mile north), Bishopsgate (1 mile east), Finsbury (1 mile north), Aldgate (1 mile east) and St Luke's (1 mile north).

Questions we are asked in City of London
Do hotels near City of London have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can we approve the colour on site?
Yes. Tell us who approves colour and we’ll plan the sample into the programme.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you use coloured sanitary silicone?
Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified.
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep the colour details for future repairs
- Look at the cured colour before the full run
- Avoid abrasive pads on coloured sealant
- Plan full-run reseals on visible elevations
Expect some change in appearance over the years. Some fading is part of normal ageing outdoors, and resealing restores the look when the time comes.
Use one product and colour reference across a building or brand. Consistency makes future work simpler.
When something else is needed
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Repairing damaged frames or cladding
- Colour variation across natural stone or brick that no single shade can match
- Exact bespoke colour matches beyond the product’s range
Not sure which it is? You can speak to us on 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
