About coloured sealant in Greater London

Colour-matched joints are often among the last items before handover. Adjacent finishes are masked and protected while we work, and we leave the area clean. A 12-month guarantee covers our workmanship. Site teams most often ask us about untidy coloured beads with ragged edges and coloured joints that have cracked with movement, across office fit-out finishes, natural stone and brick and shop-fit joinery and counters.

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 usually takes about the same time as any other sealant work, plus a little longer if a sample bead is agreed first, and our waste is bagged and taken away as we go.

We start with photos, drawings or a visit to see the finishes.
Colour options from the specified product’s range are shared with you.
The programme and access are agreed, including any phasing.
We prepare each joint, prime where needed and fit backing.
We seal in the approved colour and tool it smooth.

What you’ll pay

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Shops, offices and hotels in Greater London

In Greater London, much commercial sealant work follows refits in shops, offices and hotels in places such as London, City of Westminster and Marylebone. Visible joints call for a matched colour and a clean tooled finish.

All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in Greater London are planned with access, loading and parking in mind.

London: Refits at hotels like The Bridge Hotel (under half a mile west of London) bring joints at vanity tops, bars and reception desks that guests see every day. Units at places like Southernwood Retail Park (1.1 miles south-east of London) are refitted as brands change, and the joints have to suit each new scheme.

Why act early?

Across a chain of shops or hotels, consistency matters. Fixing the colour reference at the start keeps every site the same.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

Ask contractors to check the colour before resealing
Reseal whole runs rather than patching single joints
Keep harsh solvents away from visible joints
Protect fresh coloured sealant from dust and handling

Expect some change in appearance over the years. That is normal for exposed sealant.

Approve a sample where colour really matters. A sample in real light shows how it will look.

FAQs: Greater London

Can coloured sealant be used in washrooms and kitchens?

Yes. Sanitary silicones with anti-mould additives come in a range of colours too. We check the colour range of the sanitary product specified.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Do you work in Greater London?

Yes. Sites across Greater London are covered.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
