Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Don’t force external sealing on a damp or frosty day
- Ask cleaners to use soft cloths around fresh sealant
- Share drawings and the specification as soon as possible
- Ask installers to correct oversized gaps first
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short, and avoids a rush.
About our construction mastic in Brent Cross
The specification and the programme set the job. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. The enquiries we see most involve sealant knocked or painted over by other trades and inconsistent sealant finishes from plot to plot, across window and door perimeters, sanitary and kitchen joints and cladding and panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Brent Cross it comes down to the same thing: the right product in a properly prepared joint.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Brent Cross must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
Every job we finish is backed by a 12-month workmanship guarantee, in Brent Cross as everywhere else we work. If our installation lets you down in that time, we return and fix it.

On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself usually taking a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Point out parking and an unloading spot
- Flag any permit to work we will need
- Agree which areas must stay open

Advice
What happens if it’s left?
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. In Brent Cross, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Why us?
- Public liability insurance in place
- Standard and matched colours in many product ranges

What else we do in Brent Cross
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- Induction, permit and paperwork requirements
- The size and state of each joint
- Phasing around occupants
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- The type of building and who uses it
- The asbestos register, for older buildings
- When you need the work done
- Photos of the joints, close up and from further back
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email drawings and photos.

Mastic packages on Brent Cross sites
Site traffic in Brent Cross falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. A 2-mile radius around Brent Cross takes in a good number of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Hotel extensions and refits, at places such as The Pillar Hotel, under half a mile to the north of Brent Cross, typically run between busy periods, so the sealing is squeezed into short windows. For a contractor working at a hospital such as BMI Hendon Hospital, which lies north of Brent Cross, perimeter and facade sealing is planned around patients and deliveries. For contractors on a campus like Middlesex University, 1.6 miles north-west of Brent Cross, facade and perimeter sealing has to fit around students and term dates.
Brent Cross is about 2 miles north-west of West Hampstead, in Greater London.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
