About our coloured sealant in Hendon
Matching to anodised or powder-coated frames is a common request. The frame colour is checked against the sealant’s standard range. If the range has no close colour, a paintable sealant can sometimes be overpainted, where the specification allows. We work on powder-coated and anodised frames, cladding panels and natural stone and brick, and what we are called in for most is fit-outs with a sealant colour in the specification and joints that need to match a new RAL frame colour. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hendon is the same: the right product in a properly prepared joint.
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.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Keep harsh solvents away from visible joints
- Brief cleaners about newly sealed joints
- Check a trial length in real light
- Keep the colour details for future repairs
Expect some change in appearance over the years. That is normal for exposed sealant.
Use one product and colour reference across a building or brand. It keeps repairs and new sites consistent for whoever reseals next.
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photos, drawings or a visit to see the finishes.
- Colour options from the specified product’s range are shared with you.
- 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.
Before we start on site
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints

What else we do in Hendon
Questions we’re asked in Hendon
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method.
Will our hotel in Hendon need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.
Can weather delay the job?
Outside, 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.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you guarantee a perfect colour match?
No. We can’t promise an exact custom match. We will show you the closest colours in the specified product’s range so you can choose.
Quoting for work in Hendon
Each job is priced on its own details. The main factors are:
- Site requirements such as inductions and permits
- Access and working height
- Distance, for remote addresses
- Joint width, depth and condition
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
What to include in your enquiry
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Drawings or a marked-up plan, if available
- The type of building and who uses it
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email us.
Surface by surface
Hotel interiors
Phased work can be planned so areas stay in use. We plan around your occupancy with areas kept in use.
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, and you confirm the choice.
What Hendon’s businesses ask us to seal
Hendon has plenty of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading. Hendon has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Shop fits at places like Brent Cross Shopping Park (to the south of Hendon) leave counters, frontages and floor edges where the sealant colour is part of the finish. In a retail centre such as Brent Cross Shopping Centre, 0.5 miles to the south of Hendon, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. Shops and cafés around stations like Hendon station, 0.7 miles to the south-west of Hendon, trade from early, so work is timed around them.
Hendon is about 3 miles north-west of Hampstead, in Greater London.
