Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Coloured sealant in St John's Wood, done properly
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. Most enquiries involve old colour-matched joints lifting at the edges and shop fits that need consistent sealant colours across sites, on hotel bathrooms and public areas, cladding panels and powder-coated and anodised frames. Most enquiries from St John's Wood start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the colour-matched joints are resealed in sections so tenants are disturbed as little as possible.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Avoid piecemeal repairs on coloured joints
- Record the product and colour reference on the building file
- Avoid abrasive pads on coloured sealant
- Standardise colours across a portfolio
Give the sealant its full cure time before cleaning or handling the area. Fresh coloured beads show fingerprints and dust more easily.
Include coloured joints in a planned maintenance cycle. Replacing them on a schedule keeps finishes looking right across the building.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. All of Greater London is in the ULEZ, and kerbside space in St John's Wood can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos or drawings show us the finishes and joints.
- We send the closest colours from the product’s range.
- Tell us your site hours and access windows and we’ll plan around them.
- We prepare each joint, prime where needed and fit backing.
- The agreed colour is installed and tooled neatly.
What we need from you
- Explain the parking and delivery arrangements
- Tell staff and tenants when we will be in
- Clear stock, furniture or equipment away from the joints

Your questions answered
Can you work at a site such as The Quadrant Business Centre, by St John's Wood?
Yes. Our area takes in St John's Wood and its surroundings, with estates and business parks such as The Quadrant Business Centre included. A few photos and the unit address let us price the work.
Does a hotel in St John's Wood need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.
Does the colour affect how the joint performs?
Performance comes from the sealant type and the installation. The joint gets the product it needs, in a colour from that product’s range, installed in exactly the same way.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What do you charge?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Different surfaces, different methods
Paintable sealants
Some joints are better sealed with a paintable product and decorated. That only works where the joint and specification allow it, as paint can crack on a moving joint.
Brick and masonry
Movement joints in brickwork are long and visible. The right colour keeps them discreet without affecting the joint’s performance.
Signs you need coloured sealant in St John's Wood
Sometimes the wrong colour went in at the start. The joint may work perfectly but look out of place, and a client or designer asks for it to be redone.
Look out for the following:
- A run of joints in mismatched shades
- Colour changes after a rebrand or refit
- Dirty, discoloured joints in public areas
- Shop fits that need consistent sealant colours across sites
In a retail centre such as O2 Centre, which lies north of St John's Wood, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.
