Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Commercial premises in Northfields
The 3 miles around Northfields take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal. London premises typically come with a building manager, booked loading and house rules for contractors. We fit into those systems and phase the work so the building keeps operating.
Occupiers with premises at both Phoenix Trading Estate and West Cross Industrial Park could have the sealant at each handled under one quote. Units at places like Kew Retail Park, 2.1 miles south-east of Northfields, are refitted as brands change, and the joints have to suit each new scheme.

Coloured sealant for commercial buildings in Northfields
In retail, hospitality and office fit-outs, joints are seen close up every day. A mismatched bead can make good joinery look unfinished. The aim is a colour from the product’s range that disappears into the surface. Site teams most often ask us about dirty, discoloured joints in public areas and a run of joints in mismatched shades, on hotel bathrooms and public areas, office fit-out finishes and shop-fit joinery and counters. A specialist sealant contractor works differently from a general builder: in Northfields, that means joint design, primers and backing rod as standard.
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, and where a brand finish matters, the sealant colour is agreed first.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Common questions from Northfields clients
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Phoenix Trading Estate, by Northfields?
Yes. Our area takes in Northfields and its surroundings, with estates and business parks such as Phoenix Trading Estate included. A few photographs and the unit address let us price the work.
What do you charge?
Each job is quoted on its own details. To get one, give us a call on 01277 525 020 or email drawings and photos with a description of the work.
Do you cover Northfields?
Yes. We cover Northfields, and you can ring 01277 525 020 or send photos by email to get started.
Does a coloured sealant perform differently from a standard one?
Colour is a choice within a product’s range, not a separate type of sealant. Preparation, backing and tooling are what make it last, whatever the colour.
Will the sealant be an exact match to our finish?
No. We can’t promise an exact custom match. Sealants come in a wide range of standard colours, and we will confirm the colours available for the specified product so you can choose.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Keeping the joints sound
A few simple habits keep the new joints working:
- Standardise colours across a portfolio
- Ask contractors to check the colour before resealing
- Agree the sealant colour early and write it into the specification
- Check a trial length in real light
Use gentle cleaning methods on coloured sealant. Harsh chemicals and scouring can change how the colour looks.
Put the sealant colour into the specification or finishes schedule. When colour is left to the last minute, it is often wrong; fixing it early prevents rework.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We confirm the joint type and the product it needs.
- Your RAL reference, sample or photo is checked against that product’s colours.
- The nearest colour is agreed, with a sample bead where needed.
- The existing bead comes out, then faces are cleaned and backed.
- We mask, seal and tool to a clean line.
- We remove the masking and walk the finished joints with you.
Before we start on site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Tell us which areas need to stay in use

What we’re called out for in Northfields
Colour-matched sealant is typically requested because a standard bead has spoiled the finish: white silicone against dark cladding, grey against timber or a yellowed bead on stone. Replacing it with a suitable colour restores the intended look.
It’s worth sending us details if you spot any of the following:
- Failed coloured sealant that has split or peeled
- Stained or mouldy coloured joints in washrooms
- Previous reseals that don’t match the original
- Fit-outs with a sealant colour in the specification
For premises near Brentford station (0.8 miles south of Northfields), footfall is part of the plan: work is phased so shops and offices keep trading.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their pre-qualification and accreditations
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
Surface by surface
Powder-coated and anodised frames
Window, door and shopfront frames in RAL colours often need a sealant to suit. We compare the reference with the specified product’s colour range.
Natural stone
Stone has variation, so the aim is a colour that sits naturally against it. A stone-compatible, neutral-cure sealant avoids staining in the closest available colour.
Leave it or put it right?
Matching new joints to the existing ones is easier when the whole run is done together. Small repairs at different times rarely match. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Why us?

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
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.
